Basic Web Development Environment Setup

Windows Subsystem for Linux (WSL) and Ubuntu


Basic Web Development Environment Setup

Windows Subsystem for Linux (WSL) and Ubuntu

Test if you have Ubuntu installed by typing "Ubuntu" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads **"Ubuntu 20.04 LTS"** with "App" under it, then you have it installed. ``` 1. In the application search box in the bottom bar, type "PowerShell" to find the application named "Windows PowerShell" 2. Right-click on "Windows PowerShell" and choose "Run as administrator" from the popup menu 3. In the blue PowerShell window, type the following: `Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux` 4. Restart your computer 5. In the application search box in the bottom bar, type "Store" to find the application named "Microsoft Store" 6. Click "Microsoft Store" 7. Click the "Search" button in the upper-right corner of the window 8. Type in "Ubuntu" 9. Click "Run Linux on Windows (Get the apps)" 10. Click the orange tile labeled **"Ubuntu"** Note that there are 3 versions in the Microsoft Store… you want the one just entitled 'Ubuntu' 11. Click "Install" 12. After it downloads, click "Launch" 13. If you get the option, pin the application to the task bar. Otherwise, right-click on the orange Ubuntu icon in the task bar and choose "Pin to taskbar" 14. When prompted to "Enter new UNIX username", type your first name with no spaces 15. When prompted, enter and retype a password for this UNIX user (it can be the same as your Windows password) 16. Confirm your installation by typing the command `whoami 'as in who-am-i'`followed by Enter at the prompt (it should print your first name) 17. You need to update your packages, so type `sudo apt update` (if prompted for your password, enter it) 18. You need to upgrade your packages, so type `sudo apt upgrade` (if prompted for your password, enter it) ``` ### Git

Git comes with Ubuntu, so there's nothing to install. However, you should configure it using the following instructions.

Open an Ubuntu terminal if you don't have one open already.

  1. You need to configure Git, so type git config --global user.name "Your Name" with replacing "Your Name" with your real name.

  2. You need to configure Git, so type git config --global user.email [email protected] with replacing "[email protected]" with your real email.

Note: if you want git to remember your login credentials type:

git config --global credential.helper store

Google Chrome

Test if you have Chrome installed by typing "Chrome" in the search box in the bottom app bar that reads "Type here to search". If you see a search result that reads "Chrome" with "App" under it, then you have it installed. Otherwise, follow these instructions to install Google Chrome.

Node.js

Test if you have Node.js installed by opening an Ubuntu terminal and typing node --version. If it reports "Command 'node' not found", then you need to follow these directions.

  1. In the Ubuntu terminal, type sudo apt update and press Enter

  2. In the Ubuntu terminal, type sudo apt install build-essential and press Enter

  3. In the Ubuntu terminal, type curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash and press Enter

  4. In the Ubuntu terminal, type . ./.bashrc and press Enter

  5. In the Ubuntu terminal, type nvm install --lts and press Enter

  6. Confirm that node is installed by typing node --version and seeing it print something that is not "Command not found"!

Unzip

You will often have to download a zip file and unzip it. It is easier to do this from the command line. So we need to install a linux unzip utility.

In the Ubuntu terminal type: sudo apt install unzip and press Enter

Mocha.js

Test if you have Mocha.js installed by opening an Ubuntu terminal and typing which mocha. If it prints a path, then you're good. Otherwise, if it prints nothing, install Mocha.js by typing npm install -g mocha.

Python 3

Ubuntu does not come with Python 3. Install it using the command sudo apt install python3. Test it by typing python3 --version and seeing it print a number.

Note about WSL

As of the time of writing of this document, WSL has an issue renaming or deleting files if Visual Studio Code is open. So before doing any linux commands which manipulate files, make sure you close Visual Studio Code before running those commands in the Ubuntu terminal.

20. Remove duplicate lines from a text file

Description

Notes: //...syntax of uniq...// $uniq [OPTION] [INPUT[OUTPUT]] The syntax of this is quite easy to understand. Here, INPUT refers to the input file in which repeated lines need to be filtered out and if INPUT isn't specified then uniq reads from the standard input. OUTPUT refers to the output file in which you can store the filtered output generated by uniq command and as in case of INPUT if OUTPUT isn't specified then uniq writes to the standard output.

Now, let's understand the use of this with the help of an example. Suppose you have a text file named kt.txt which contains repeated lines that needs to be omitted. This can simply be done with uniq.

code
sudo apt install uniq
uniq -u input.txt output.txt

21. Remove lines containing string

Description

Notes:

Notes:

code
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch assets/_index.html' HEAD

27. OVERWRITE LOCAL CHANGES

Description

Important: If you have any local changes, they will be lost. With or without --hard option, any local commits that haven't been pushed will be lost.[*] If you have any files that are not tracked by Git (e.g. uploaded user content), these files will not be affected.

Notes: First, run a fetch to update all origin/ refs to latest:

code
git fetch --all
## Backup your current branch:

git branch backup-master
## Then, you have two options:

git reset --hard origin/master
## OR If you are on some other branch:

git reset --hard origin/<branch_name>
## Explanation:
## git fetch downloads the latest from remote without trying to merge or rebase anything.

## Then the git reset resets the master branch to what you just fetched. The --hard option changes all the files in your working tree to match the files in origin/master
git fetch --all
git reset --hard origin/master

28. Remove Submodules

Description: To remove a submodule you need to

Notes:

Delete the relevant section from the .gitmodules file. Stage the .gitmodules changes git add .gitmodules Delete the relevant section from .git/config. Run git rm --cached path_to_submodule (no trailing slash). Run rm -rf .git/modules/path_to_submodule (no trailing slash). Commit git commit -m "Removed submodule " Delete the now untracked submodule files rm -rf path_to_submodule

## FUNCTIONS


## The function refers to passed arguments by position (as if they were positional parameters), that is, $1, $2, and so forth.
## $@ is equal to "$1" "$2"... "$N", where N is the number of positional parameters. $# holds the number of positional parameters.

function functname() {
  shell commands
}

unset -f functname  # deletes a function definition
declare -f          # displays all defined functions in your login session


## FLOW CONTROLS


statement1 && statement2  # and operator
statement1 || statement2  # or operator

-a                        # and operator inside a test conditional expression
-o                        # or operator inside a test conditional expression

## STRINGS

str1 == str2               # str1 matches str2
str1 != str2               # str1 does not match str2

## COMMAND-LINE PROCESSING CYCLE


## The default order for command lookup is functions, followed by built-ins, with scripts and executables last.
## There are three built-ins that you can use to override this order: `command`, `builtin` and `enable`.

command  # removes alias and function lookup. Only built-ins and commands found in the search path are executed
builtin  # looks up only built-in commands, ignoring functions and commands found in PATH
enable   # enables and disables shell built-ins

eval     # takes arguments and run them through the command-line processing steps all over again


## INPUT/OUTPUT REDIRECTORS


cmd1|cmd2  # pipe; takes standard output of cmd1 as standard input to cmd2
< file     # takes standard input from file
> file     # directs standard output to file
>> file    # directs standard output to file; append to file if it already exists
>|file     # forces standard output to file even if noclobber is set
n>|file    # forces output to file from file descriptor n even if noclobber is set
<> file    # uses file as both standard input and standard output
n<>file    # uses file as both input and output for file descriptor n
n>file     # directs file descriptor n to file
n<file     # takes file descriptor n from file
n>>file    # directs file description n to file; append to file if it already exists
n>&        # duplicates standard output to file descriptor n
n<&        # duplicates standard input from file descriptor n
n>&m       # file descriptor n is made to be a copy of the output file descriptor
n<&m       # file descriptor n is made to be a copy of the input file descriptor
&>file     # directs standard output and standard error to file
<&-      # closes the standard input
>&-      # closes the standard output
n>&-     # closes the ouput from file descriptor n
n<&-     # closes the input from file descripor n

|tee <file># output command to both terminal and a file (-a to append to file)


## PROCESS HANDLING


## To suspend a job, type CTRL+Z while it is running. You can also suspend a job with CTRL+Y.
## This is slightly different from CTRL+Z in that the process is only stopped when it attempts to read input from terminal.
## Of course, to interrupt a job, type CTRL+C.

myCommand &  # runs job in the background and prompts back the shell

jobs         # lists all jobs (use with -l to see associated PID)

fg           # brings a background job into the foreground
fg %+        # brings most recently invoked background job
fg %-      # brings second most recently invoked background job
fg %N        # brings job number N
fg %string   # brings job whose command begins with string
fg %?string  # brings job whose command contains string

kill -l               # returns a list of all signals on the system, by name and number
kill PID              # terminates process with specified PID
kill -s SIGKILL 4500  # sends a signal to force or terminate the process
kill -15 913          # Ending PID 913 process with signal 15 (TERM)
kill %1               # Where %1 is the number of job as read from 'jobs' command.

ps           # prints a line of information about the current running login shell and any processes running under it
ps -a        # selects all processes with a tty except session leaders

trap cmd sig1 sig2  # executes a command when a signal is received by the script
trap "" sig1 sig2   # ignores that signals
trap - sig1 sig2    # resets the action taken when the signal is received to the default

disown <PID|JID>    # removes the process from the list of jobs

wait                # waits until all background jobs have finished
sleep <number>      # wait # of seconds before continuing

pv                  # display progress bar for data handling commands. often used with pipe like |pv
yes                 # give yes response everytime an input is requested from script/process


## TIPS & TRICKS


## set an alias
cd; nano .bash_profile
> alias gentlenode='ssh [email protected] -p 3404'  # add your alias in .bash_profile

## to quickly go to a specific directory
cd; nano .bashrc
> shopt -s cdable_vars
> export websites="/Users/mac/Documents/websites"

source .bashrc
cd $websites


## DEBUGGING SHELL PROGRAMS


bash -n scriptname  # don't run commands; check for syntax errors only
set -o noexec       # alternative (set option in script)

bash -v scriptname  # echo commands before running them
set -o verbose      # alternative (set option in script)

bash -x scriptname  # echo commands after command-line processing
set -o xtrace       # alternative (set option in script)

trap 'echo $varname' EXIT  # useful when you want to print out the values of variables at the point that your script exits

function errtrap {
  es=$?
  echo "ERROR line $1: Command exited with status $es."
}

trap 'errtrap $LINENO' ERR  # is run whenever a command in the surrounding script or function exits with non-zero status

function dbgtrap {
  echo "badvar is $badvar"
}

trap dbgtrap DEBUG  # causes the trap code to be executed before every statement in a function or script
## ...section of code in which the problem occurs...
trap - DEBUG  # turn off the DEBUG trap

function returntrap {
  echo "A return occurred"
}

trap returntrap RETURN  # is executed each time a shell function or a script executed with the . or source commands finishes executing

↞↠ Getting Started With GatsbyJS ↞↠ #

🚀 Quick start

  1. Create a Gatsby site.

    Use the Gatsby CLI to create a new site, specifying the default starter.

   # create a new Gatsby site using the default starter
   gatsby new my-default-starter https://github.com/gatsbyjs/gatsby-starter-default
  1. Start developing.

    Navigate into your new site's directory and start it up.

   cd my-default-starter/
   gatsby develop
  1. Open the source code and start editing!

    Your site is now running at http://localhost:8000!

    Note: You'll also see a second link:http://localhost:8000/___graphql. This is a tool you can use to experiment with querying your data. Learn more about using this tool in the Gatsby tutorial.

    Open the my-default-starter directory in your code editor of choice and edit src/pages/index.js. Save your changes and the browser will update in real time!

🧐 What's inside?

A quick look at the top-level files and directories you'll see in a Gatsby project.

.
├── node_modules
├── src
├── .gitignore
├── .prettierrc
├── gatsby-browser.js
├── gatsby-config.js
├── gatsby-node.js
├── gatsby-ssr.js
├── LICENSE
├── package-lock.json
├── package.json
└── README.md
  1. /node_modules: This directory contains all of the modules of code that your project depends on (npm packages) are automatically installed.

  2. /src: This directory will contain all of the code related to what you will see on the front-end of your site (what you see in the browser) such as your site header or a page template. src is a convention for "source code".

  3. .gitignore: This file tells git which files it should not track / not maintain a version history for.

  4. .prettierrc: This is a configuration file for Prettier. Prettier is a tool to help keep the formatting of your code consistent.

  5. gatsby-browser.js: This file is where Gatsby expects to find any usage of the Gatsby browser APIs (if any). These allow customization/extension of default Gatsby settings affecting the browser.

  6. gatsby-config.js: This is the main configuration file for a Gatsby site. This is where you can specify information about your site (metadata) like the site title and description, which Gatsby plugins you'd like to include, etc. (Check out the config docs for more detail).

  7. gatsby-node.js: This file is where Gatsby expects to find any usage of the Gatsby Node APIs (if any). These allow customization/extension of default Gatsby settings affecting pieces of the site build process.

  8. gatsby-ssr.js: This file is where Gatsby expects to find any usage of the Gatsby server-side rendering APIs (if any). These allow customization of default Gatsby settings affecting server-side rendering.

  9. LICENSE: This Gatsby starter is licensed under the 0BSD license. This means that you can see this file as a placeholder and replace it with your own license.

  10. package-lock.json (See package.json below, first). This is an automatically generated file based on the exact versions of your npm dependencies that were installed for your project. (You won't change this file directly).

  11. package.json: A manifest file for Node.js projects, which includes things like metadata (the project's name, author, etc). This manifest is how npm knows which packages to install for your project.

  12. README.md: A text file containing useful reference information about your project.

🎓 Learning Gatsby

Looking for more guidance? Full documentation for Gatsby lives on the website. Here are some places to start:

  • **For most developers, we recommend starting with our in-depth tutorial for creating a site with Gatsby**.** It starts with zero assumptions about your level of ability and walks through every step of the process.
  • **To dive straight into code samples, head to our documentation**.** In particular, check out the Guides, API Reference, and Advanced Tutorials sections in the sidebar.

Gatsby With Netlify CMS

This tutorial will use gatsby-personal-starter-blog, a Gatsby starter based on the official gatsby-starter-blog. The differences are that gatsby-personal-starter-blog is configured to run the blog on a subdirectory, /blog, and comes pre-installed with Netlify CMS for content editing. It also adds VS Code highlighting for code blocks.

Prerequisites

Set up a Netlify CMS-managed Gatsby site in 5 steps

Step 1

Open your Terminal and run the following command from the Gatsby CLI to create a new Gatsby site using gatsby-personal-starter-blog.

gatsby new [your-project-name] https://github.com/thomaswangio/gatsby-personal-starter-blog

Step 2

Once the Gatsby site is finished installing all the packages and dependencies, you can now go into the directory and run the site locally.

cd [your-project-name]
gatsby develop

Now you can go to http://localhost:8000 to see your new site, but what's extra cool is that Netlify CMS is pre-installed and you can access it at http://localhost:8000/admin

A CMS, or content management system, is useful because you can add content like blog posts from a dashboard on your site, instead of having to add posts manually with Markdown. However, you'll likely want to be able to access the CMS from a deployed website, not just locally. For that, you'll need to deploy to Netlify through GitHub, set up continuous deployment, and do a few configurations. You'll go over this in Step-5.

Step 3

Open the project in your code editor and open static/admin/config.yml. Replace your-username/your-repo-name with your GitHub username and project name. This step is important for managing and deploying the Netlify CMS interface.

backend:
-  name: test-repo

+  name: github
+  repo: your-username/your-repo-name

Customizing your site

Head into gatsby-config.js and you can edit your siteMetadata, add a Google Analytics tracking ID, and your app icon/favicon. Test out the edits for the deployed build by quitting the development server and running gatsby build && gatsby serve.

You'll likely also want to edit the README.md and package.json files to include your own project details.

Step 4

Open github.com and create a new repository, with the same name as your project. Push your new Gatsby site's code to GitHub using the following Terminal commands:

git init
git add .
git commit -m "initial commit"
git remote add origin https://github.com/[your-username]/[your-repo-name].git
git push -u origin master

Then, open app.netlify.com and add a "New site from Git". Choose your newly created repo and click on "Deploy site" with the default deployment settings.

Note: if you don't see the correct repo listed, you may need to install or reconfigure the Netlify app on GitHub.

Netlify Dashboard for Creating a new site

Step 5

To make sure that Netlify CMS has access to your GitHub repo, you need to set up an OAuth application on GitHub. The instructions for that are here: Netlify's Using an Authorization Provider.

For the "Homepage URL" – you can use your Netlify subdomain, [name-of-your-site].netlify.com, or you can use a custom domain. To customize the subdomain, look for the "Edit site name" field under "Domain Management" for your project on the Netlify app. To connect your Netlify site to your custom domain instead, see Netlify’s instructions on custom domains.

Once you've configured an authentication provider then you'll be able to use Netlify CMS at your deployed site to add new posts.

Netlify and GitHub Authorization

Copy the credentials of your new app listed on GitHub OAuth Apps and install a new auth provider on Netlify using them.

Setting up access control

Benefits of Netlify CMS, GitHub, and Netlify Workflow

Congrats! Now that Netlify CMS is successfully configured to your project, every time you add a new post, the content will be stored in your repository and versioned on GitHub because Netlify CMS is Git-based. Also, thanks to Netlify's Continuous Deployment, a new version will be deployed every time you add or edit a post.

You can learn more about Netlify CMS and how to configure it further in the Netlify CMS documentation

Inside a Gatsby project, you may see some or all of the following folders and files:

/|
-- /.cache
|-- /plugins
|-- /public
|-- /src    
|-- /api    
|-- /pages    
|-- /templates    
|-- html.js
|-- /static
|-- gatsby-config.js
|-- gatsby-node.js
|-- gatsby-ssr.js
|-- gatsby-browser.js

Folders

  • /.cache Automatically generated. This folder is an internal cache created automatically by Gatsby. The files inside this folder are not meant for modification. Should be added to the .gitignore file if not added already.

  • /plugins This folder hosts any project-specific ("local") plugins that aren't published as an npm package. Check out the plugin docs for more detail.

  • /public Automatically generated. The output of the build process will be exposed inside this folder. Should be added to the .gitignore file if not added already.

  • /src This directory will contain all of the code related to what you will see on the frontend of your site (what you see in the browser), like your site header, or a page template. "src" is a convention for "source code".

    • /api JavaScript and TypeScript files under src/api become functions automatically with paths based on their file name. Check out the functions guide for more detail.
    • /pages Components under src/pages become pages automatically with paths based on their file name. Check out the pages recipes for more detail.
    • /templates Contains templates for programmatically creating pages. Check out the templates docs for more detail.
    • html.js For custom configuration of default .cache/default_html.js. Check out the custom HTML docs for more detail.
  • /static If you put a file into the static folder, it will not be processed by webpack. Instead it will be copied into the public folder untouched. Check out the assets docs for more detail.

Files

  • gatsby-browser.js: This file is where Gatsby expects to find any usage of the Gatsby browser APIs (if any). These allow customization/extension of default Gatsby settings affecting the browser.
  • gatsby-config.js: This is the main configuration file for a Gatsby site. This is where you can specify information about your site (metadata) like the site title and description, which Gatsby plugins you'd like to include, etc. Check out the config docs for more detail.
  • gatsby-node.js: This file is where Gatsby expects to find any usage of the Gatsby node APIs (if any). These allow customization/extension of default Gatsby settings affecting pieces of the site build process.
  • gatsby-ssr.js: This file is where Gatsby expects to find any usage of the Gatsby server-side rendering APIs (if any). These allow customization of default Gatsby settings affecting server-side rendering.

Misc Misc

The file/folder structure described above reflects Gatsby-specific files and folders. Since Gatsby sites are also React apps, it's common to use standard React code organization patterns such as folders like /components and /utils inside /src. The React docs have more information on a typical React app folder structure.

In this guide, you'll learn Gatsby's approach to layouts, how to create and use layout components, and how to prevent layout components from unmounting.

Gatsby's approach to layouts

Gatsby does not, by default, automatically apply layouts to pages (there are, however, ways to do so which will be covered in a later section). Instead, Gatsby follows React's compositional model of importing and using components. This makes it possible to create multiple levels of layouts, e.g. a global header and footer, and then on some pages, a sidebar menu. It also makes it possible to pass data between layout and page components.

What are layout components?

Layout components are for sections of your site that you want to share across multiple pages. For example, Gatsby sites will commonly have a layout component with a shared header and footer. Other common things to add to layouts are a sidebar and/or navigation menu. On this page for example, the header at the top is part of gatsbyjs.com's layout component.

How to create layout components

It is recommended to create your layout components alongside the rest of your components (e.g. into src/components/).

Here is an example of a very basic layout component at src/components/layout.js:

import React from "react"export default function Layout({ children }) {  return (    <div style={{ margin: `0 auto`, maxWidth: 650, padding: `0 1rem` }}>       {children}    </div>   )}

How to import and add layout components to pages

If you want to apply a layout to a page, you will need to include the Layout component and wrap your page in it. For example, here is how you would apply your layout to the front page:

import React from "react"import Layout from "../components/layout"export default function Home() {  return (    <Layout>       <h1> I'm in a layout!</h1>     </Layout>   );}

Repeat for every page and template that needs this layout.

How to prevent layout components from unmounting

As mentioned earlier, Gatsby does not, by default, automatically wrap pages in a layout component. The "top level" component is the page itself. As a result, when the "top level" component changes between pages, React will re-render all children. This means that shared components like navigations will unmount and remount. This will break CSS transitions or React state within those shared components.

If you need to set a wrapper component around page components that won't get unmounted on page changes, use the wrapPageElement browser API and the SSR equivalent.

Alternatively, you can prevent your layout component from unmounting by using gatsby-plugin-layout, which implements the wrapPageElement APIs for you.

Adding Markdown Pages | Gatsby

Excerpt

Gatsby can use Markdown files to create pages in your site. You add plugins to read and understand folders with Markdown files and from them…


Gatsby can use Markdown files to create pages in your site. You add plugins to read and understand folders with Markdown files and from them create pages automatically.

Here are the steps Gatsby follows for making this happen.

  1. Read files into Gatsby from the filesystem
  2. Transform Markdown to HTML and frontmatter to data
  3. Add a Markdown file
  4. Create a Collection Route component for the Markdown files

Read files into Gatsby from the filesystem

Use the plugin gatsby-source-filesystem to read files.

Install

npm install gatsby-source-filesystem

Add PluginAdd plugin

Open gatsby-config.js to add the gatsby-source-filesystem plugin. The path option is how you set the directory to search for files.

module.exports = {  siteMetadata: {
    title: "My Gatsby Site",  },  
plugins: [    { 
     resolve: `gatsby-source-filesystem`,      
options: {
        name: `markdown-pages`,      
  path: `${__dirname}/src/markdown-pages`,      
},  
  },  
],}

Completing the above step means that you've "sourced" the Markdown files from the filesystem. You can now "transform" the Markdown to HTML and the YAML frontmatter to JSON.

Transform Markdown to HTML and frontmatter to data using gatsby-transformer-remark

You'll use the plugin gatsby-transformer-remark to recognize files which are Markdown and read their content. The plugin will convert the frontmatter metadata part of your Markdown files as frontmatter and the content part as HTML.

Install transformer plugin

npm install gatsby-transformer-remark

Configure plugin

Add this to gatsby-config.js after the previously added gatsby-source-filesystem.

module.exports = {  siteMetadata: {
    title: "My Gatsby Site",  },  
plugins: [    { 
     resolve: `gatsby-source-filesystem`,      
options: {
        name: `markdown-pages`,      
  path: `${__dirname}/src/markdown-pages`,      
},  
  },  
  `gatsby-transformer-remark`,  ],
}

Add a Markdown file

Create a folder in the /src directory of your Gatsby application called markdown-pages. Now create a Markdown file inside it with the name post-1.md.

Frontmatter for metadata in Markdown files

When you create a Markdown file, you can include a set of key/value pairs that can be used to provide additional data relevant to specific pages in the GraphQL data layer. This data is called "frontmatter" and is denoted by the triple dashes at the start and end of the block. This block will be parsed by gatsby-transformer-remark as YAML. You can then query the data through the GraphQL API from your React components.

src/markdown-pages/post-1.md

---slug: "/blog/my-first-post"date: "2019-05-04"title: "My first blog post"---

What is important in this step is the key pair slug. The value that is assigned to the key slug is used in order to navigate to your post.

Create a Collection Route for the Markdown files

Create src/pages/{MarkdownRemark.frontmatter__slug}.js and add the following code:

src/pages/{MarkdownRemark.frontmatter__slug}.js

import React from "react"
import { graphql } from "gatsby"export default function Template({  data, }) {  const { markdownRemark } = data   const { frontmatter, html } = markdownRemark  return (    <div className="blog-post-container">       <div className="blog-post">         <h1> {frontmatter.title}</h1>         <h2> {frontmatter.date}</h2>         <div          className="blog-post-content"          dangerouslySetInnerHTML={{ __html: html }}        />       </div>     </div>   )}export const pageQuery = graphql`  query($id: String!) {    markdownRemark(id: {
 eq: $id }) {      html      frontmatter {        date(formatString: "MMMM DD, YYYY")        slug        title      }    }  }`

Two things are important in the file above:

  1. A GraphQL query is made in the second half of the file to get the Markdown data. Gatsby has automagically given you all the Markdown metadata and HTML in this query's result.

    Note: To learn more about GraphQL, consider this excellent resource

  2. The result of the query is injected by Gatsby into the component as the data prop. props.data.markdownRemark is the property that has all the details of the Markdown file.

Next you could create a page component at src/pages/blog/index.js to serve as a listing page for all your blog posts.

This should get you started on some basic Markdown functionality in your Gatsby site. You can further customize the frontmatter and the component file to get desired effects!

For more information, have a look in the working example using-markdown-pages. You can find it in the Gatsby examples section.

Overview

The _.get() method in Lodash retrieves the object’s value at a specific path.

If the value is not present at the object’s specific path, it will be resolved as undefined. This method will return the default value if specified in such a case.

Syntax

_.get(object, path, defaultValue)

Parameters

This method accepts the following parameters:

  • object: The object in which the given path will be queried.
  • path: The path used to retrieve the value from the object.
  • defaultValue: The default value that will be returned for resolved values that are undefined.

Return value

This method will return the value at the specified path if found. Otherwise, it will return the default value if specified.

Example

Let’s look at an example of the _.get() method in the code snippet below:

Explanation

In the HTML tab:

  • Line 5: We import the lodash script.

In the JavaScript tab:

  • Lines 2 to 15: We create an object to perform a query.

  • Line 18: We define a variable collegeYopPath to get the value.

  • Lines 19: We use the _.get() method and pass the object, collegeYopPath, and a default value as parameters.

  • Line 22: We define a variable falsyPath to get the value.

  • Lines 23: We use the _.get() method and pass the object, falsyPath and a default value as parameters.

Output

  • The _.get() method at line 19 contains a valid path, and therefore the expression is resolved, and 2021 is printed on the console.
  • The _.get() method at Line 23 contains an invalid path, and therefore the expression is resolved as undefined.

Overview

The _.get() method in Lodash retrieves the object’s value at a specific path.

If the value is not present at the object’s specific path, it will be resolved as undefined. This method will return the default value if specified in such a case.

Syntax

_.get(object, path, defaultValue)

Parameters

This method accepts the following parameters:

  • object: The object in which the given path will be queried.
  • path: The path used to retrieve the value from the object.
  • defaultValue: The default value that will be returned for resolved values that are undefined.

Return value

This method will return the value at the specified path if found. Otherwise, it will return the default value if specified.

Example

Let’s look at an example of the _.get() method in the code snippet below:

In the HTML tab:

  • Line 5: We import the lodash script.

In the JavaScript tab:

  • Lines 23: We use the _.get() method and pass the object, falsyPath and a default value as parameters.

Output

  • The _.get() method at line 19 contains a valid path, and therefore the expression is resolved, and 2021 is printed on the console.
  • The _.get() method at Line 23 contains an invalid path, and therefore the expression is resolved as undefined.
