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';

Other packages similar to @trivago/prettier-plugin-sort-imports

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.

module.exports = {
  "printWidth": 80,
  "tabWidth": 4,
  "trailingComma": "all",
  "singleQuote": true,
  "jsxBracketSameLine": true,
  "semi": true,

  "importOrderSeparation": true,
  "importOrderCaseInsensitive": true,
}

APIs

importOrder

A collection of:

• Regular expressions in string format. The plugin uses new RegExp to evaluate regular expression. E.g. node.source.value.match(new RegExp(val)) Here, val is the string provided in import order.
• Special words (optional):
  • <THIRD_PARTY_MODULES> - marks the position between RegExps, where the not matched imports will be placed. By default, it's the top position (above all the groups in importOrder).

importOrderCaseInsensitive

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';

importOrderSeparation

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

importOrderSortSpecifiers

A boolean value to enable or disable sorting of the imports module declarations. It is disabled by default

importOrderParserPlugins

A collection of parser names 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 needs.

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

module.exports = {
  "printWidth": 80,
  "tabWidth": 4,
  "trailingComma": "all",
  "singleQuote": true,
  "jsxBracketSameLine": true,
  "semi": true,
  "importOrder": ["^@core/(.*)$", "^@server/(.*)$", "^@ui/(.*)$", "^[./]"],
  "importOrderSeparation": true,
  "importOrderCaseInsensitive": true,
  "importOrderParserPlugins" : ["jsx", "typescript", "[\"decorators\", { \"decoratorsBeforeExport\": true }]"]
}

How does import sort work ?

The plugin extracts the imports which are defined in importOrder. These imports are local imports. The imports which are not part of the importOrder is considered as 3rd party imports.

After, the plugin sorts the local imports and 3rd party imports using

natural sort algorithm.

In the end, the plugin returns final imports with 3rd party imports on top and local imports at the end.

The 3rd party imports position (it's top by default) can be overrided using the <THIRD_PARTY_MODULES> special word.

FAQ / Troubleshooting

Q. How can I add the RegEx imports in the importOrder list ?

You can define the RegEx in the importOrder. For example if you want to sort the following imports:

import React from 'react';
import classnames from 'classnames';
import z from '@server/z';
import a from '@server/a';
import s from './';
import p from '@ui/p';
import q from '@ui/q';

then the importOrder would be ["^@ui/(.*)$","^@server/(.*)$", '^[./]']. Now, the final output would be as follows:

import classnames from 'classnames';
import React from 'react';
import p from '@ui/p';
import q from '@ui/q';
import a from '@server/a';
import z from '@server/z';
import s from './';

Q. How can I move react and classnames to place between my RegEx imports without hardcoding?

You can define the <THIRD_PARTY_MODULES> special word in the importOrder. For example above, the importOrder would be like ["^@ui/(.*)$", "^@server/(.*)$", "<THIRD_PARTY_MODULES>", '^[./]']. Now, the final output would be as follows:

import p from '@ui/p';
import q from '@ui/q';
import a from '@server/a';
import z from '@server/z';
import classnames from 'classnames';
import React from 'react';
import s from './';

Q. How can I run examples in this project ?

There is a examples directory. The examples file can be formatted by using npm run example command.

npm run example examples/example.tsx

Q. How to use the plugin with *.d.ts files ?

The plugin automatically ignores the *.d.ts files. We encourage you to declare the *.d.ts files in .prettierignore. Read more here.

Q. How does the plugin handle the first comment in the file.

The plugin keeps the first comment as it is in the file. The plugin also removes the new lines in between first comment and the first import. input:

// comment

import a from 'a'

output:

// comment
import a from 'a'

Q. I'm getting error about experimental syntax.

If you are using some experimental syntax and the plugin has trouble parsing your files, you might getting errors similar to this:

SyntaxError: This experimental syntax requires enabling one of the following parser plugin(s): ...

To solve this issue, you can use the new option importOrderParserPlugins in your .prettierrc and pass an array of plugin names to be used.
