@typescript-eslint/explicit-function-return-type error detected in JS file
Run ESLint with eslint-config-love on a file like the following.
/**
* @param {string} username - user name
* @returns {void}
*/
const sayHello = (username) => {
console.log(`Hello, ${username}`)
}
const myName = 'Alice'
sayHello(myName)
Then, the following error is then detected.
5:29 error Missing return type on function @typescript-eslint/explicit-function-return-type
This is an odd behavior since JavaScript does not allow for return types.
Solution
Perhaps this rule should be enabled for TS files only.
{
"rules": {
// disable the rule for all files
"@typescript-eslint/explicit-function-return-type": "off",
},
"overrides": [
{
// enable the rule specifically for TypeScript files
"files": ["*.ts", "*.mts", "*.cts", "*.tsx"],
"rules": {
"@typescript-eslint/explicit-function-return-type": "error",
},
},
],
}
cf. https://typescript-eslint.io/rules/explicit-function-return-type/#configuring-in-a-mixed-jsts-codebase
Or should eslint-config-love be configured on the user side to apply only to TS files?
