CLI toolbox for common scripts for my our projects

The problem

I We do a bunch of open source and want to make it easier to maintain so many projects.

This solution

This is a CLI that abstracts away all configuration for my our open source projects for linting, testing, building, and more.

Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's devDependencies:

yarn add -D @hover/javascript

Usage

This is a CLI and exposes a bin called hover-scripts. You'll find all available scripts in src/scripts.

This project actually dogfoods itself. If you look in the package.json, you'll find scripts with node src {scriptName}. This serves as an example of some of the things you can do with hover-scripts.

Overriding Config

Unlike react-scripts, hover-scripts allows you to specify your own configuration for things and have that plug directly into the way things work with hover-scripts. There are various ways that it works, but basically if you want to have your own config for something, just add the configuration and hover-scripts will use that instead of it's own internal config. In addition, hover-scripts exposes its configuration so you can use it and override only the parts of the config you need to.

This can be a very helpful way to make editor integration work for tools like ESLint which require project-based ESLint configuration to be present to work.

So, if we were to do this for ESLint, you could create an .eslintrc with the contents of:

{"extends": "./node_modules/@hover/javascript/eslint.js"}

Or, for babel, a .babelrc with:

{"presets": ["@hover/javascript/babel"]}

Or, for jest:

const { jest: jestConfig } = require('@hover/javascript/jest');
module.exports = Object.assign(jestConfig, {
  // your overrides here

  // for test written in Typescript, add:
  transform: {
    '\\.(ts|tsx)$': '<rootDir>/node_modules/ts-jest/preprocessor.js',
  },
});

Note: hover-scripts intentionally does not merge things for you when you start configuring things to make it less magical and more straightforward. Extending can take place on your terms. I Kent think[s] this is actually a great way to do this.

For the record, so do I (Jamie)
