Introduction
ESLint Plugin Command is a special kind of ESLint plugin, that by default, does nothing. Instead of checking for code quality, it serves as a micro-codemod tool triggers by special comments on-demand, resuse the infrastructure of ESLint.
For example, one of the built-in commands, /// to-function
allows you to convert a single arrow function expression to a function declaration.
/// to-function
const foo = async <T>(msg: T): void => {
console.log(msg)
}
Will be transformed to this when you hit save with your editor or run eslint . --fix
. After executing the command, the comment will also be removed along with the transformation:
async function foo<T>(msg: T): void {
console.log(msg)
}
One more example that /// to-promis-all
converts a sequence of await
expressions to await Promise.all()
:
/// to-promise-all
const foo = await bar().then
const { get } = await import('lodash-es')
Will be transformed to:
const [
foo,
{ get },
] = await Promise.all([
bar(),
import('lodash-es'),
] as const)
