eslint-plugin-sort-imports-requires
An ESLint plugin to sort both import and require declarations in a unified manner.
Status
Motivation
ESLint's sort-imports
only works for import
statements. However, require
statements are still being widely used. We needed to validate import
and require
statements in a similar way throughout our codebase and we couldn't find an OSS package that would address this need with the features we require.
This plugin is a drop-in replacement to sort-imports
with a few extra features:
- Provides autofix for potentially unsafe situations (see
unsafeAutofix
). - Allows sorting by aliases. (see
useAliases
). - Allows restoring the old ESLint behavior where
multiple
type corresponds to all named imports, regardless of how many are imported (see useOldSingleMemberSyntax
).
Installation
You'll first need to install ESLint:
npm install eslint --save-dev
Next, install eslint-plugin-sort-imports-requires
:
npm install eslint-plugin-sort-imports-requires --save-dev
Usage
Add sort-imports-requires
to the plugins section of your ESLint configuration file and configure its rules. Here's an example:
import sortImportRequires from 'eslint-plugin-sort-imports-requires';
export default [
{
plugins: {
'sort-imports-requires': sortImportRequires
},
rules: {
'sort-imports-requires/sort-imports': ['error', { unsafeAutofix: true }],
'sort-imports-requires/sort-requires': ['error', { unsafeAutofix: true }]
}
}
];
Supported Rules
sort-imports
and sort-requires
These are the only supported rules and can be configured independently. Both have exactly the same options as ESLint's sort-imports
rule, with a few more options:
unsafeAutofix
(default: false
)useAliases
(default: true
)useOldSingleMemberSyntax
(default: false
)
unsafeAutofix
Whether to autofix potentially unsafe scenarios automatically when the --fix
flag is used when calling eslint
.
The current scenarios considered unsafe are:
- Sorting import / require declarations because they can have side-effects, therefore the order in which they are executed might matter. That's the reason why the built-in ESLint
sort-imports
rule does not autofix. - Sorting dynamic keys with potential side-effects, e.g.:
const { [foo()]: bar } = require('bar')
. In this scenario, the order in which keys are declared might matter.
Enable this option at your own discretion.
useAliases
Whether to use aliases when sorting.
Consider the following import:
import { foo as bar } from 'some-module';
If useAliases
is enabled, bar
is used when sorting. If it was disabled, foo
would have been used instead.
useOldSingleMemberSyntax
Whether to restore the old ESLint behavior where multiple
type corresponds to all named imports (regardless of how many are imported), while the single
type corresponds only to default imports.
