What is @trivago/prettier-plugin-sort-imports?

@trivago/prettier-plugin-sort-imports is a Prettier plugin that automatically sorts your import statements in a consistent and customizable manner. It helps maintain a clean and organized codebase by ensuring that import statements are ordered according to specified rules.

What are @trivago/prettier-plugin-sort-imports's main functionalities?

Sort imports alphabetically

This feature sorts the import statements alphabetically by module name.

import React from 'react';
import { useState } from 'react';
import { render } from 'react-dom';

Group imports by type

This feature groups import statements by their type, such as external libraries, internal modules, and styles.

import React from 'react';
import { useState } from 'react';
import { render } from 'react-dom';
import './styles.css';
import utils from './utils';

Customizable sorting order

This feature allows you to define a custom sorting order for your import statements, such as placing React imports at the top, followed by other external libraries, and then internal modules.

import React from 'react';
import { useState } from 'react';
import { render } from 'react-dom';
import utils from './utils';
import './styles.css';

eslint-plugin-import

eslint-plugin-import is an ESLint plugin that helps validate proper imports and enforce import order. It provides a wide range of rules for managing import statements, including sorting them. Unlike @trivago/prettier-plugin-sort-imports, which is a Prettier plugin, eslint-plugin-import is used with ESLint.

import-sort

import-sort is a tool and library for sorting ES6 imports. It can be used as a standalone tool or integrated with various editors and build tools. It offers customizable sorting configurations similar to @trivago/prettier-plugin-sort-imports but is not tied to Prettier.

prettier-plugin-organize-imports

prettier-plugin-organize-imports is a Prettier plugin that uses the TypeScript language service to organize imports. It automatically removes unused imports and sorts the remaining ones. It is similar to @trivago/prettier-plugin-sort-imports but focuses on TypeScript projects.

Usage

Add an order in prettier config file.

module.exports = {
  "printWidth": 80,
  "tabWidth": 4,
  "trailingComma": "all",
  "singleQuote": true,
  "semi": true,
  "importOrder": ["^@core/(.*)$", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],
  "importOrderSeparation": true,
  "importOrderSortSpecifiers": true
}

APIs

importOrder

type: Array<string>

A collection of Regular expressions in string format.

"importOrder": ["^@core/(.*)$", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],

Default behavior: The plugin moves the third party imports to the top which are not part of the importOrder list. To move the third party imports at desired place, you can use <THIRD_PARTY_MODULES> to assign third party imports to the appropriate position:

"importOrder": ["^@core/(.*)$", "<THIRD_PARTY_MODULES>", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],

importOrderSeparation

type: boolean

default value: false

A boolean value to enable or disable the new line separation between sorted import declarations group. The separation takes place according to the importOrder.

"importOrderSeparation": true,

importOrderSortSpecifiers

type: boolean

default value: false

A boolean value to enable or disable sorting of the specifiers in an import declarations.

importOrderGroupNamespaceSpecifiers

type: boolean

default value: false

A boolean value to enable or disable sorting the namespace specifiers to the top of the import group.

importOrderCaseInsensitive

type: boolean

default value: false

A boolean value to enable case-insensitivity in the sorting algorithm used to order imports within each match group.

For example, when false (or not specified):

import ExampleView from './ExampleView';
import ExamplesList from './ExamplesList';

compared with "importOrderCaseInsensitive": true:

import ExamplesList from './ExamplesList';
import ExampleView from './ExampleView';

importOrderParserPlugins

type: Array<string>

default value: ["typescript", "jsx"]

Previously known as experimentalBabelParserPluginsList.

A collection of plugins for babel parser. The plugin passes this list to babel parser, so it can understand the syntaxes used in the file being formatted. The plugin uses prettier itself to figure out the parser it needs to use but if that fails, you can use this field to enforce the usage of the plugins' babel parser needs.

To pass the plugins to babel parser:

  "importOrderParserPlugins" : ["classProperties", "decorators-legacy"]

To pass the options to the babel parser plugins: Since prettier options are limited to string, you can pass plugins with options as a JSON string of the plugin array: "[\"plugin-name\", { \"pluginOption\": true }]".

  "importOrderParserPlugins" : ["classProperties", "[\"decorators\", { \"decoratorsBeforeExport\": true }]"]

To disable default plugins for babel parser, pass an empty array:

importOrderParserPlugins: []

How does import sort work ?

The plugin extracts the imports which are defined in importOrder. These imports are considered as local imports. The imports which are not part of the importOrder is considered as third party imports.

After, the plugin sorts the local imports and third party imports using natural sort algorithm.

In the end, the plugin returns final imports with third party imports on top and local imports at the end.

The third party imports position (it's top by default) can be overridden using the <THIRD_PARTY_MODULES> special word in the importOrder.
