    This package provides a collection of reasonable default prettier, eslint files for fast-paced JS development. This is especially useful when you need to unify coding style across multiple projects & teams.


    Make sure you have the following VSCode extensions installed:

    • ESLint
    • Prettier

    Option 1: Auto-install

    In your project folder, run:

    ([ ! -e package.json ] && npm init -y); npm i -D @byteflowjs/rcpack && npx rcpack create

    This will generate the following files in your project (overwrite existing ones):

    ├── .eslintrc.js --------> Customize rules here
    ├── .prettierrc.js ------> Customize formats here
    ├── .eslintignore
    ├── .prettierignore
    ├── .vscode
    │   └── settings.json

    Now, VSCode will format your code on save + show lint issues on the bottom bar. You may need to reload VSCode for the extensions to apply these configs.

    Note, lint issues are shown for all currently opened tabs only. To lint ALL files in the project, in editor:

    • Hit cmd+p
    • Type >run task
    • Choose eslint: lint whole folder

    If for some reason, you want to delete these files...

    npx rcpack delete

    Option 2: Manual install

    Install the package as a dev dependency.

    npm i -D @byteflowjs/rcpack

    In your .eslintrc.js file, write:

    module.exports = {
      extends: [require.resolve('@byteflowjs/rcpack/eslint')],
      rules: {
        // Your rules here

    In your .prettierrc.js file, write:

    const prettier = require('@byteflowjs/rcpack/prettier');
    module.exports = {
      // Your rules here

    To achieve format on-save in VSCode. In root directory, create a .vscode folder. Inside, create a settings.json file. Write:

      "editor.defaultFormatter": "esbenp.prettier-vscode",
      "editor.formatOnSave": true,
      "editor.formatOnPaste": false,
      "eslint.lintTask.enable": true

    We need to reload VSCode to so ESLint and Prettier extensions take effect. cmd+shift+p and type reload window.

    Now, on file save, VSCode will automatically format your code and lint errors.

    Format & lint pre-commit

    In examples/package.json, check devDependencies and script section to see an example of how to format code & lint out the errors prior to pushing your code to repository.
