The problem

Creating new tradeshift npm libraries requires a lot of boilerplate configuration, and is prone to errors. Configurations will often diverge or never be updated.

This solution

This is a CLI that abstracts away all configuration for 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:

npm install --save-dev tradeshift-scripts

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

Usage

This is a CLI and exposes a bin called tradeshift-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 tradeshift-scripts.

To use the after-success hooks and automatic semantic release, you need to set up your build env with GH_TOKEN and NPM_TOKEN.

If you want to automatically publish coverage reports to codecov, add a CODECOV_TOKEN.

Overriding Config

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

Or, for babel, a .babelrc with:

{"presets": ["tradeshift-scripts/babel"]}

Or, for jest:

const { jest: jestConfig } = require('tradeshift-scripts/config');
module.exports = Object.assign(jestConfig, {
	// your overrides here
});

Note: tradeshift-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.

Inspiration

This is inspired by react-scripts.
