presetter

Sharing configurations for building tools across projects is painful. How many time you've copied configs for babel, eslint, vitest, typescript or the life cycle scripts in package.json? How many dev dependencies you have to install before you can kick start a project?

What's more, what if you want to update configs for all projects? 🤦‍♂️

Presetter is a utility for setting up building tools for your project from a template. This means with just only two dev packages, namely this package and your favorite template preset, all essential development packages, such as typescript, eslint and vitest, together with their configuration files provided by the preset, are automatically setup for you upon the project's initialization.

Quick Start

FULL DOCUMENTATION IS AVAILABLE HERE

1. Bootstrap your project with a preset (e.g. presetter-preset-esm)

npx presetter use 

That's. One command and you're set.

2. Develop and run life cycle scripts provided by the preset

At this point, all development packages specified in the preset are installed, and now you can try to run some example life cycle scripts (e.g. run prepare) provided by the template.

Usage

Presetter is shipped with a command line interface, which has 4 commands

⚙ presetter: your preset configurator

Commands:
  presetter use   adopt the specified preset to the project
  presetter bootstrap     apply the specified preset to the project
  presetter run           run a template script
  presetter unset         remove all artifacts created by the preset

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]

Adopting a Preset

Note: No matter which situation you're in below, you don't need to bootstrap the preset as it's done automatically.

To a Fresh Project

To adopt a preset to an empty project, simple run presetter use on your project root. By running this command, it will

• create a .presetterrc file under the root, detailing the preset setting,
• add a presetter bootstrap command to the prepublish life cycle script in your package.json, and
• bootstrap the preset at the end of the process.

To an Existing Project

To adopt a preset to an existing project with all the development and life cycle script setup, follow the steps below:

1. Check if there's anything you want to keep your own version (e.g. eslintrc) instead of the one provided by the preset
2. Remove any unnecessary dev dependencies, .config files or life cycle scripts
3. Make sure presetter bootstrap will be executed in the post installation life cycle.
4. Add your preset via presetter use

Bootstrapping Everything Provided by the Preset

A preset is merely a collection of configuration files and dependency declarations, they have to be installed to the adopting project and it's what presetter bootstrap for.

You would have to run presetter bootstrap manually

• after running npm install and presetter bootstrap isn't set up in the prepublish life cycle, or
• you installed a new packages via npm.

Running a Life Cycle Script

You can combine you local life cycle script definition with the template provided by the preset.

Simple run npx presetter run or an equivalent short cut npx run , or if you prefer to run the script in the conventional way, you can set life cycle scripts in package.json to something like

{
  "scripts": {
    "build": "run build",
    "coverage": "run coverage",
    "lint": "run lint",
    "prepare": "run prepare",
    "prepublishOnly": "run prepublishOnly",
    "release": "run release --",
    "test": "run test --",
    "watch": "run watch"
  }
}

When you run the command, presetter will combine the scripts, place them into a temporary package.json and run the task via npm run as usual.

PROTIPS: Install presetter globally via npm install -g presetter and you can ignore the need to call npx all the time.

Customization

Presetter support customization in two ways.

Preset Customization

If your preset support customization, you can supply the customization parameter via the config field in .presetterrc. e.g. For presetter-preset-esm, you can adding an expression to .gitignore with the following in .presetterrc:

{
  "preset": "presetter-preset-esm",
  "config": {
    "gitignore": ["
