ESLint configuration if installed.
"importSorter" section in package.json
import-sorter.json (File name is configurable)
Prettier configuration if installed
.editorconfig
VS Code "editor" and "files" settings
VS Code "tsImportSorter" settings

Here are all configs in package.json under "importSorter" section and their default values:

{
  "importSorter": {
    // When to auto format imports/exports. Valid values are 'off' or 'onSave'.
    "autoFormat": "onSave",

    // Whether to format exports as well.
    "formatExports": true,

    // Disable formatting for files matching regular expressions.
    "exclude": ["node_modules"],

    // Sort import declarations by paths or first names. Valid values are 'paths' or 'names'.
    "sortImportsBy": "paths",

    // Grouping rules for path patterns for imports. {} is the fall-back group.
    "groupRules": ["^react(-dom)?$", "^@angular/", "^vue$", {}, "^[@]", "^[.]"],

    "sortRules": {
      // Sorting rule for import paths. Valid values are 'none' or string array.

import-sorter.json has all configs above. Example:

{
  "maxLineLength": 100,
  "quoteMark": "double",
  "tabSize": 4,
  "insertFinalNewline": false
}

ESLint Compatibility

If installed, ESLint and plugins rules will be detected and consulted, so that the result code will comply to the lint rules.

Currently supported rules are:

If there are conflicts between user config and ESLint rules, the ESLint rules will win to avoid any lint errors.

For more info about how the conflicts are resolved, please check the ESLint Compatibility wiki.

Ignore files or declarations

There are a few ways to exclude files from inspection:

Add path patterns to exclude or excludeGlob in user or workspace settings in VSCode.

"tsImportSorter.configuration.exclude": ["regexPattern"],
"tsImportSorter.configuration.excludeGlob": ["globPattern"],

Add path patterns to package.json or import-sorter.json.
- All path patterns are merged together instead of overwritten.
- Use forward-slash (/) as path separator no matter in MacOS, *nix or Windows.
Add the following comment at the beginning of the source file and keep at least one empty line from the next declaration:

// ts-import-sorter: disable

[Other code]

/* ts-import-sorter: disable */

[Other code]

Note:

Excluded paths and file disable-comments are ignored if the formatting is triggered manually, i.e. from Command Palette, editor context menu or shortcut.

To exclude a specific import or export declaration from formatting, please add the following as its leading or trailing comments:

// ts-import-sorter: disable
import Excluded from 'import/sorter';

export { Excluded } from 'import/sorter'; /* ts-import-sorter: disable */

To disable formatting for all exports, just set "formatExports": false in the config.

Maximum names per line

Whether to wrap an import declaration is decided by maxBindingNamesPerLine and maxDefaultAndBindingNamesPerLine, as well as maxLineLength.

Whether to wrap an export declaration is decided by maxExportNamesPerLine, as well as maxLineLength.

`maxBindingNamesPerLine`

For a declaration importing only binding names, this value determines how many names are allowed before wrapping.

For example, if you set:

"maxBindingNamesPerLine": 2,

then

import { A } from 'a';    // No wrap as there is 1 name
import { B, C } from 'b'; // No wrap as there are 2 names

import {
  D,
  E,
  F,
} from 'c';   // Wrapped as there are more than 2 names

`maxDefaultAndBindingNamesPerLine`

For a declaration importing default and binding names, this value determines how many names are allowed before wrapping.

For example, if you set:

"maxDefaultAndBindingNamesPerLine": 2,

then

import A from 'a';        // No wrap as there is 1 name
import B, { C } from 'b'; // No wrap as there are 2 names
import D, {
  E,
  F,
} from 'c'; // Wrapped as there are more than 2 names

`maxExportNamesPerLine`

For export {} or export {} from 'x' declarations, this value determines how many names are allowed before wrapping.

For example, if you set:

"maxExportNamesPerLine": 2,

then

export { A };             // No wrap as there is 1 name
export { B, C } from 'b'; // No wrap as there are 2 names
export {
  D,
  E,
  F,
} from 'c'; // Wrapped as there are more than 2 names

`maxNamesPerWrappedLine`

If an import/export declaration is wrapped, this value decides how many names there are per line.

For example, if you set:

"maxNamesPerWrappedLine": 2,

then

import {
  A, B,
  C, D,
  E,
} from 'a'; // There are 2 names at most per wrapped line

export {
  A, B,
  C, D,
  E,
}; // There are 2 names at most per wrapped line

Grouping Rules

JS/TS Import/Export Sorter can put imports into different groups separated by empty lines (configurable), based on the rules defined in groupRules.

A grouping rule defines:

Types of imports to apply.
Path pattern to match.
How to sort imports, by paths or first names, inside the group.
Sorting Rules for paths and names within the group.
Sub-groups to further adjust the order.

Notes:

There are NO blank lines between sub-groups.
Use emptyLinesBetweenGroups to change empty lines between groups.
A group can have its own sortImportsBy regardless of the global option, and sub groups will respect it.

For example, "groupRules": ["^react$", {}, "^[.]"] defines 3 groups (and their order):

"^react$": matches any named imports from exact path "react".
{}: is the fall-back group, i.e. any imports that don't match any other groups will fall into this group.
"^[.]": matches any named imports from paths starting with ".".

The following is an example of the results:

import React from 'react';

import { TextDocument } from 'vscode';

import MyInput from './MyInput';

Notes:

By default, script imports are in the first group if you don't explicitly define rules for them.
Script imports will NOT be sorted within a (sub) group, though sub groups may change their order.
Exports will NOT be grouped. Grouping Rules are only for imports.

For a complete guide, please refer to the Wiki.

Sorting Rules

You can customize sorting rules for all imports and exports, or imports within a group, on:

How to compare import paths;
How to compare imported/exported names;

Note:

Exports will NOT be sorted based on paths. Only names within an export are sorted.
Script imports will NOT be sorted.

You can decide:

Whether to compare letters case-sensitively or -insensitively;
The rank among lower-case letters, upper-case letters and '_';

Here is an example:

"sortRules": {
  "paths": ["_", "aA"],
  "names": ["_", "aA"]
}

The above ["_", "aA"] means:

Strings are compared case-insensitively, and lower-case goes first in case of a tie.
[, \, ], ^, _ and `(backtick) are in front of letters ([a-zA-Z]).

A sorted array might be ['_', 'a', 'A', 'b', 'B'].

You can also disable sorting by specifying "none" in sortRules, e.g.:

"sortRules": {
  "paths": "none",
  "names": "none"
}

If you set paths to "none", import declarations will not be sorted.

If you set names to "none", names will not be sorted within an import or export declaration.

Note:

Setting paths or names to null doesn't disable sorting but uses the fall-back sorting rules, i.e. `["AZ", "", "az"]`._

For more details and how to construct your own rules, please read the Wiki.

Unused Imports Removal

By default all unused imports are removed. In some cases you might want to keep the import even if it's unused. For example to keep import tw from 'twin.macro' you can do the following:

"keepUnused": ["twin.macro"]

This is equivalent to a more verbose version:

"keepUnused": [{ "path": "twin.macro" }]

Another example is import styled, { css } from 'styled-components' and if you want to keep css import while styled is removed if unused, you can achieve that with the following configuration:

"keepUnused": [
  { "path": "styled-components", "names": ["css"] }
]

Both path and names are converted to regular expressions so you can get really wild here.

Note:

You DON'T need to add React (React) and h (Stencil) to keepUnused as they are handled already.
By default, "keepUnused" array is empty, i.e. DON'T keep any unused imports.
To keep ALL unused imports you can simply set:

"keepUnused": [".*"]
