Prettier for Firebase rules

Formatter for Firebase Realtime Database Rules

Usage

Install this package:

npm install --save-dev prettier prettier-plugin-firebase

Then add this line to your prettier.config.js:

  plugins: ["prettier-plugin-firebase-database"],

Finally, run prettier:

prettier --write firebase-database.rules

By default, this plugin would try to parse all files with the extension .rules as Firebase Realtime Database Rules. You can customize this behavior though configuration overwrites in your prettier.config.js or equivalent:

/**
 * @see https://prettier.io/docs/en/configuration.html
 * @type {import("prettier").Config}
 */
const config = {
  plugins: ['prettier-plugin-firebase-database'],
  overrides: [
    {
      files: '*.rules',
      options: {
        parser: 'prettier-plugin-firebase-database',
      },
    },
  ],
};

export default config;
