Description

CLI toolbox for common scripts for JavaScript / TypeScript projects. Inspired by "Tools without config" and kcd-scripts

Synopsis

  1. Create a project:
    • npm init my-project
    • If TypeScript: add types into package.json such as:
      • { "types": "lib/index" }
  2. Install:
    • npm install --save-dev moe-scripts
  3. Use scripts:
    • npm run build -- --watch
    • npm run build:doc
    • npm run validate
    • npm run commit
    • npm run release
    • ... etc.

Beware

Build yours using script-helper.

Instead of using this toolbox directly, consider creating yours using script-helper. This library is an example usage for script-helper and not meant for general use.

If it fits you, fork it, because it may change from version to version according to needs of author.

Problem

There are lots of configuration and boilerplate to start and maintain a JavaScript project. It is very tiresome to update libraries and configurations within multiple projects. See "Tools without config"

Solution

This toolkit is provided as an npm module and every configuration for linting, testing, building and more are initialized with a single command and updated simply updating a single npm package.

Configuration

This toolkit exposes a bin called moe-scripts. All scripts are stored in lib/scripts and all configurations are stored either in lib/config or in root of the library.

Toolkit decide whether a project is a TypeScript project or JavaScript project by looking types entry in package.json.

moe-scripts init is automatically executed after package install and creates configuration files and entries in package.json if they do not exist. See init script below.

All scripts can be further refined used arguments related to used tool within that script. It is mostly avoided to provide extra besides original ones of the tool parameters if really not necessary.

Overriding Configuration

Most of the configuration can be extended by native extend mechanism of the related library. Those which cannot be extended such as .gitignore or can be extended but behaves according to location of extended file such as tsconfig.json are used with symbolic links pointing to a file in this toolkit.

All of the configuration can be overridden.

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.

ESLint

Create an .eslintrc with the contents of:

{"extends": "./node_modules/moe-scripts/eslint.js"}

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

TSLint

It is extendible via:

{ "extends": "moe-scripts/tslint.json" }

Note: tslint.json is not a symbolic link in source root. There is no safe place to link it, because lib is not always available in source and src is not available in npm package.

Babel

Or, for babel, a .babelrc with:

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

Jest

const {jest: jestConfig} = require('moe-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',
  },
})

Inspiration

This toolkit is based on and very heavily inspired by kcd-scripts. I'm also grateful for his Tools without config article. I created this as a fork and a separate toolkit instead of contributing it, because he mentioned that, like me, kcd-scripts are a personal project and specific to his needs. (Like this one is specific to my needs).

API

Modules

build

Build project using TypeScript, Babel or rollup based on project type.

TypeScript

  • Copies js and d.ts files from src to lib using rsync, because tsc does not allow --allowJs and --declaration parameters at the same time.
  • Cleans target directory before build.

Babel

  • If no --ignore parameter presents, ignores by default: tests, mocks, test_supplements, test_helpers, *.(test|spec).(js|ts|jsx|tsx)
commit

Starts commitizen interactive CLI to commit staged files adhering conventional-changelog using cz-conventional-changelog plugin.

contributors

WIP

doc

Generates documentation.

  • Creates or updates README.md file from README.hbs handlebars template file and JSDoc comments in source files.
  • Generates table of contents.
  • If no --configure parameter is present and no configuration file is available, uses builtin configuration provided by this library.
  • If no --files parameter given, uses all files recursively in src directory.
  • If no --template parameter given, uses README.hbs` in project root.
format

Formats project using prettier.

  • If no config provided (--config, prettier.config.js or prettierrc in package.json) uses builtin configuration provided by this library.
  • If no --ignore-path parameter provided or no .prettierignore file is present uses builtin ignore file provided by this library.
info

  • If project has no ESLint configuration (.eslintrc.js or eslintConfig in package.json etc.) or no --config is given, uses builtin configuration provided by this library.
  • If no --ignore-path argument is given uses .gitignore.
  • Uses --cache by default. (Can be disabled by --no-cache).
precommit

Script to be executed automatically just before commit. Utilizes lint-staged

This script is defined in .huskyrc.js as required. It is used by husky and contains lint-staged config.

  • If no config provided (--config, lint-staged.config.js or lint-staged in package.json) uses builtin configuration provided by this library.
  • Builds README.md and adds it to git
  • Executes lint-staged.
    • format (If not opted out) and add to git
    • lint
    • test (executes test related to changed files)
  • If opted in, executes validation script.
reset

test

Test project using Jest

  • Sets BABEL_ENV and NODE_ENV to test.
  • If not in CI, precommit stage, or following arguments are not present --no-watch, --coverage, --updateSnapshot or --watchAll, watches changes.
  • If no config provided (--config, jest.config.js etc.) uses builtin configuration provided by this library.
