Report automation

Build Status

This is a POC of a report automation suite using AWS cloud

Introduction

This repo contains the automation stack for the automatic reports review. Is a project build with a mono repository approach. This project was created with the goal of automatic take reports from the automation and store into a DB (accessed by Grafana).

Project overview

The stack of this project is built on top of AWS. The IaC used is the AWS-CDK (https://docs.aws.amazon.com/cdk/api/v2/).

How it works

Once that an automation suite is completed the reports (usually in JSON) is uploaded into an S3 Bucket. Once that the file is uploaded one of the lambdas that are listening on the S3 take the report and formats it. The formatted report is sent to an SQS that trigger another lambda, that will insert datas into the DB.

Project setup

  • npm install
  • npm run build

Available commands

  • npm run lint
  • npm run format
  • npm run test

Project structure

The project is a mono-repository with two workspaces: packages and services

Packages

Inside packages we have shared lib and the cdk project. You can find the configuration of tsconfig and eslint for example.

Usage of tsconfig

There is a project under packages/tsconfig.json where you can find different available ts configuration (with the name *.json). You can import these configuration into every project adding this dependencies:

 "@packages/tsconfig": "*",

and then you can add a tsconfig file into the project with this format

{
  "extends": "@packages/tsconfig/base.json",
  "compilerOptions": {
    "outDir": ".dist",
    "rootDir": "./",
    "baseUrl": "src"
  },
  "include": ["./src", "./test"]
}

Usage of eslint

As for tsconfig you can import the eslint lib into any project as a dependency

 "@packages/eslint-config-custom": "*",

and then use in the project by adding the following eslintrc.json file

{
  "root": true,
  // This tells ESLint to load the config from the package `eslint-config-custom`
  "extends": ["@packages/eslint-config-custom/ts"]
}

Deploy

The deploy of the application is provided by the AWS CDK. The CDK is used to deploy the lambdas on AWS. You can find the files of cdk under the folder packages/aws-cdk/. The entrypoint of the cdk is the file bin/aws-cdk.ts. Before deploying an application you have to setup an account on AWS and export the access keys. Then you have to setu your environment by runnning (you need to install the aws-cli before this)

aws configure
cd packages/aws-cdk
npx cdk bootstrap
npx cdk synth

After this you can back to the root of the project and you can create a .env file

touch .env

After this you have to fill out your .env with the env variables that you can find in the file .env.sample After this you're ready for deploy.

. ./load_dotenv.sh ## only in local
npm run deploy

Test and Coverage

The coverage of the project is provided by nyc. For getting the coverage run these commands (the build command is not mandatory but in most cases it prevent cache issues :) )

npm run build
npm run coverage

You'll see the results of coverage under the folder coverage/ by opening the file index.html
