Rule to require parenthesis in arrow function body expressions.
npm install eslint-plugin-arrow-body-parensRule to require parenthesis in arrow function body expressions.
You'll first need to install ESLint:
``
$ npm i eslint --save-dev
Next, install eslint-plugin-arrow-body-parens:
`
$ npm install eslint-plugin-arrow-body-parens --save-dev
Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-arrow-body-parens globally.
Add arrow-body-parens to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:
`json`
{
"plugins": [
"arrow-body-parens"
]
}
Then configure the rules you want to use under the rules section.
`json``
{
"rules": {
"arrow-body-parens/parens": [ "error" ]
}
}
* parens - ensure arrow expression bodies are wrapped in parenthesis and that the opening parenthesis starts on the same line as the arrow.
