eslint-plugin-prefer-arrow-functions
Advanced tools
An ESLint Plugin to Lint and auto-fix plain Functions into Arrow Functions, in all cases where conversion would result in the same behaviour (Arrow Functions do not support
this,arguments, ornew.targetfor example).
npm install --save-dev eslint eslint-plugin-prefer-arrow-functions
Try it yourself at ASTExplorer.net by pasting code snippets in the top left panel, the results will appear in the bottom right panel.
Add the plugin to the plugins section and the rule to the rules section in
your .eslintrc. The default values for options are listed in this example.
{
"plugins": ["prefer-arrow-functions"],
"rules": {
"prefer-arrow-functions/prefer-arrow-functions": [
"warn",
{
"classPropertiesAllowed": false,
"disallowPrototype": false,
"returnStyle": "unchanged",
"singleReturnOnly": false
}
]
}
}
classPropertiesAllowedWhen true, functions defined as
class instance fields
will be converted to arrow functions when doing so would not alter or break
their behaviour.
disallowPrototypeWhen true, functions assigned to a prototype will be converted to arrow
functions when doing so would not alter or break their behaviour.
returnStyle"implicit", arrow functions such as x => { return x; } will be
converted to x => x."explicit", arrow functions such as x => x will be converted to
x => { return x; }."unchanged" or not set, arrow functions will be left as they were.singleReturnOnlyWhen true, only function declarations which only contain a return
statement will be converted. Functions containing block statements will be
ignored.
This option works well in conjunction with ESLint's built-in arrow-body-style set to
as-needed.
