Prettier Plugin: Organize Imports for Astro

A plugin that makes Prettier organize your imports (i. e. sorts, combines and removes unused ones) in Astro files using the organizeImports feature of the TypeScript language service API.

Demo

Installation

npm install -D prettier prettier-plugin-astro-organize-imports

Recommended configuration

// .prettierrc
{
  "plugins": ["prettier-plugin-astro-organize-imports"],
  "overrides": [
    {
      "files": "*.astro",
      "options": {
        "parser": "astro"
      }
    }
  ]
}

Usage

After following the steps in the 'Installation' section, the plugin will function when you run the Prettier formatting command.

Files containing the substring // organize-imports-ignore or // tslint:disable:ordered-imports will be skipped and won't be processed by this plugin.

The plugin provides an option named astroOrganizeImportsMode that lets you choose the mode of formatting. The available options are:

All: This is the default option. It removes unused imports, coalesces imports from the same module, and sorts imports.
SortAndCombine: This option coalesces imports from the same module and sorts imports.
RemoveUnused: This option removes the unused imports.

You can specify the mode in your Prettier configuration file as follows:

// .prettierrc
{
  // ..
  "astroOrganizeImportsMode": "All" // or "SortAndCombine" or "RemoveUnused"
}

Remember to replace "All" with "SortAndCombine" or "RemoveUnused" depending on your preferences.

Compatibility with other Prettier plugins

This plugin uses Prettier APIs that can only be used by one plugin at a time, making it incompatible with other Prettier plugins implemented the same way. To solve this we've added explicit per-plugin workarounds that enable compatibility with the following Prettier plugins:

prettier-plugin-astro
prettier-plugin-tailwindcss

One limitation with this approach is that prettier-plugin-astro-organize-imports must be loaded last. You can do this by listing each of your Prettier plugins in the plugins array:

// .prettierrc
{
  // ..
  "plugins": [
    "prettier-plugin-astro",
    "prettier-plugin-tailwindcss",
    "prettier-plugin-astro-organize-imports" // MUST come last
  ],
  "overrides": [
    {
      "files": "*.astro",
      "options": {
        "parser": "astro"
      }
    }
  ]
}
