🏋️‍♂️ εἵλως (eilos)

The hard working, opinionated build toolset for javascript applications, with pluggable opinions

eilos makes it easy to use and maintain the lifecycle operations of your node project while keeping the amount of dependencies and configuration you need to a minimum.

It is heavily inspired by aegir, but is focused more on the versatility of the "opinitions" rather than forcing a specific paradigm to the user.

Usage

Right after you have configured your node module, do the following:

1. Add eilos to your dependencies:

yarn add -D eilos

2. Add an eilos preset you like to your dependencies:

yarn add -D eilos-preset-typescript

3. Use eilos for every life-cycle script on your project:

{
  "scripts": {
    "build": "eilos build",
    "dev": "eilos dev",
    "test": "eilos test",
    "lint": "eilos lint",
  }
}

Configuration

eilos aims to minimise the amount of configuration required by assuming some deafults.

The base package has no configuration options. They are all provided by the preset you are using.

For example, when using the eilos-preset-typescript preset:

• The default entry point is src/index.ts
• The default static files directory is static/
• The default build directory is build/

You can override these defaults by providing a .eilos.js configuration file:

/** @typedef { import('eilos-preset-typescript').UserConfig } UserConfig */

/**
 * @type {UserConfig}
 */
module.exports = {
  // Define the entry point
  entry: "src/index.js",
  // Define thestatic files
  staticSrcDir: "static",

  // Manually override specific configuration options for the packages used
  // by the profile (refer to the profile documentation)

  webpack: {
    // Webbpack options
  },
  typescript: {
    // Typescript compiler options
  },
  jest: {
    // Jest options
  },
  prettier: {
    // Prettier options
  }
}
