This is a mono-repo. It contains several packages, all controlled from a top level packages.json.
Each project has its own package.json file containing package specific configuration, however don't run yarn install from a package project; instead run it from the top level.
If you run yarn install from a package then you may well get an unhelpful error like this:
Error: ENOENT: no such file or directory, symlink '…\fozzie-components\packages\…' -> '…\fozzie-components\node_modules\@justeat\…'
If this happens, delete all the node_modules folders throughout and then run yarn install from the root directory again.
In some rare cases modules specified in the components own package.json file can sometimes fail to resolve / install correctly. This can lead to errors like:
Example error: The following module could not be found, please run yarn add @moduleName to install it.
There's two solutions you could try from the root of the project which may fix this:
- yarn cache clean
- yarn build
Turborepo is an intelligent build system optimized for JavaScript and TypeScript codebases. We use Turborepo to facilitate the execution of all our build scripts within the PIE monorepo.
In order to speed up local development / CI workflows, we use Turborepo's remote caching functionality to publish build artifacts to AWS S3. This ensures that only modified packages have their build tasks executed.
In order to take advantage of this functionality, you must set the TURBO_TOKEN environment variable on your local machine. Please reach out to the design system team for the value of this token.
Once enabled you'll see 'Remote caching enabled' when executing a packages node task.
It is recommended to run the following tasks at the root of the monorepo to ensure tasks are executed for the required components:
build
test
lint
For other test tasks you can execute in a number of ways:
# Run Component tests for all components
# Note: Ensure Storybook is not running when running the following commands
cd ./fozzie-components
yarn storybook:build
yarn storybook:serve-static
yarn test-component:chromeOR
# Run Component tests for individual f-* package
# Note: Ensure Storybook is not running when running the following commands
cd ./fozzie-components
yarn storybook:build
yarn storybook:serve-static
# And in another window
yarn test-component:chrome --filter=@justeat/f-user-messageWe have created several optional mixin helpers in Fozzie. Here's an example of how to use it:
Note: Importing the optional mixin and using @include in the common.scss file of your component doesn't work if you have module enabled on your SFC.
<style lang="scss" module>
@include pageBanner();
</style>You can add reusable styles to the common.scss file. This can be useful for components that use sub-components and may wish to share mixins, functions and variables.
Every component comes with a vue.config.js file that makes the common.scss file available under the namespace common like so:
`@use "../assets/scss/common.scss";`
To access anything from the common file, simply prefix the value like so:
// Fake values used for demonstration
.someClass {
color: common.$fontColor;
line-height: common.line-height();
@include common.truncate();
}
You could remove the need for namespacing by using something like @use "../assets/scss/common.scss" as * however utilising the namespace makes it much easier to understand where a value is coming from.
To run storybook first you must run the following at the the top level
yarn build to build the require packages for storybook to run.
Then run yarn storybook:serve to start storybook, which will open on localhost:8080.
Alternatively, you can run yarn build:changed and yarn storybook:serve-changed to just view the component you're working on, as well as any of it's dependencies / dependants.
If you wish to view a single component in Storybook during development, you can do this by opening the components *.stories.js file in your IDE and running the Storybook - Run Currently Open Story File task which can be found in the debug tab on the left. (This only works with VS Code).
This is particuarly useful as it prevents a bug where Storybook pulls in other components stylesheets (See here).
We use Husky to manage our git hooks.
When you make a commit, the following scripts will run as part of our pre-commit hook.
If you wish to skip this Husky hook, simply add the --no-verify argument when making your commit.
For example: git commit -m "Refactor f-button" --no-verify .
