Prettier Plugin: Sort imports

A prettier plugin that sorts import statements by either their length or alphabetically.

Example:

Installation

npm install --save-dev prettier-plugin-sort-imports

Usage

The plugin will be loaded by Prettier automatically. No configuration needed. It will sort by import statement length by default.

Add to Prettier Config

1. Create a file named prettier.config.js in your project's root directory.
2. Add the following contents:

module.exports = {
	// For prettier 3
	sortingMethod: 'lineLength',
	plugins: ['./node_modules/prettier-plugin-sort-imports/dist/index.js'],
};

module.exports = {
	// For prettier 2
	sortingMethod: 'lineLength',
	pluginSearchDirs: ['./node_modules'],
	plugins: ['./node_modules/prettier-plugin-sort-imports/dist/index.2.js'],
};

Known issues

When using with certain other plugins

When combined with other prettier plugins that also modify the way JS/TS are formatted (such as prettier-plugin-tailwindcss) some issues may occur. See this issue for more details and the fix.

Options:

• sortingMethod: 'alphabetical' | 'lineLength' (default) - What to sort the individual lines by. alphabetical sorts by the import path and lineLength sorts by the length of the import. Note that alphabetical sorting looks at the whole import path, so imports starting with ../ are ranked lower.
• stripNewlines: true | false (default). Determines whether newlines between blocks of imports are stripped. If the only thing between two blocks is whitespace or comments, the whitespace will be stripped and the blocks are sorted as one big one. The comment sticks to whichever import it was above initially.
• importTypeOrder: ('NPMPackages' | 'localImportsValue' | 'localImportsType' | 'localImports' | 'all')[]. An array that determines the order in which different import types are sorted. The default is ['all'], which does no sorting of different import types. Import type are sorted according to the order in which they appear in this array. Note that, other than the 'all' type, you can not specify an imcomplete array. See different types for which other types they can be combined with. Explanations of different types:
  • 'NPMPackages': All NPM packges that are listed in your package.json fall into this category. If you have multiple package.json files you can specify them using the packageJSONFiles option. Can only be used with one of the other local import types (either 'localImportsValue', 'localImportsType' or 'localImports')
  • 'localImportsValue': All local imports that are declared with a value import foo from './foo' falls into this category. Can only be used if NPMPackages is also specified and if localImportsType is also specified.
  • 'localImportsType': All local imports that are imported as a type. import type foo from './foo' falls into this category. Only available in typecript. Can only be used if NPMPackages is also specified and if localImportsValue is also specified.
  • 'localImports': All local imports that are declared with a value or a type. import foo from './foo' and import type foo from './foo' both fall into this category. Can only be used if NPMPackages is also specified.
  • 'all': All imports fall into this category.
• packageJSONFiles: string[]. Set to ['package.json'] by default. Lists the package.json files to be used for the 'NPMPackages' import type. Note that if you specified ['all'] for the importTypeOrder option (or specified none at all), this is not used.
• newlineBetweenTypes: boolean. Set to false by default. Determines whether a newline should be inserted between different import types.

Files containing the string // sort-imports-ignore are skipped. You can also ignore sections by using // sort-imports-begin-ignore and // sort-imports-end-ignore.
