How to use this package?

This package can be used at multiple levels, from low to high:

High Level API

• The scripts from src/scripts can be directly used as an npm script field.

Mid Level API

• The Webpack config files can be used to quickly setup some build/dev scripts by importing createConfig or createDevConfig from src/configs.
• Some useful utility functions include createEnvironmentHash that can be used in other packages in different scenarios.

Low Level API

• If you want to write a custom Webpack config:
  • To handle different file types while using Webpack you can look in src/configs/loaders/*.
  • Some modules provide utilties that can be used in packages for build or non-build related purposes:
    1. choosePort - This helps you find a free port given a default port.
    2. src/utils/consoleHelpers.ts - Provides helper functions such as clearConsole.

Scripts

• The dev-atri-app is used to start Atri's development server.

• The create-atri-app is used to create a new Atri project.

Add environment variables to client side code

All the environment variables that needs to be embedded in the application (client side) must start with ATRI_APP_. Some environment variables are available to client side by default such as NODE_ENV.

You can also use .env file or .env.${MODE}.local files to specify environment variables (again, variables that start with ATRI_APP_ will only be available on client side).

Working details

The src/utils/extractParams.ts has a function with the same name that helps extract the required information for a build process from different sources such as environment variables, command line arguments and build.config.js. All the scripts from src/bin call extractParams() to extract these necessary information.

Generate index.html

Geneartes index.html when generateIndexHtml is set to true.

Notes
