bappo-scripts 🛠📦

CLI toolbox for common scripts for Bappo projects

---

The problem

We need to set up linting, testing, building for every project (platform and customer projects). It's tedious to set up a new project and hard to keep the tooling up-to-date.

This solution

This is a CLI that abstracts away all configuration for linting, testing, building, and more.

Installation

Requires node version >= 10.18

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

yarn add --dev @bappo/scripts

Usage

This is a CLI and exposes a bin called bappo-scripts. I don't really plan on documenting or testing it super duper well because it's really specific to my needs. 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 bappo-scripts.

Overriding Config

Unlike react-scripts, bappo-scripts allows you to specify your own configuration for things and have that plug directly into the way things work with bappo-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 bappo-scripts will use that instead of it's own internal config. In addition, bappo-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/@bappo/scripts/eslint.js"}

Note: for now, you'll have to include an .eslintignore in your project until this eslint issue is resolved.

Or, for babel, a .babelrc with:

{"presets": ["@bappo/scripts/babel"]}

Or, for jest:

const { jest: jestConfig } = require('@bappo/scripts/config');
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: bappo-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 think this is actually a great way to do this.
