@putout/eslint

Wrapper that simplifies ESLint API and makes it compatible with 🐊Putout.

Install

npm i @putout/eslint

API

ESLint begins his work as a formatter when 🐊Putout done his transformations. That's why it used a lot in different parts of application, for testing purpose and using API in a simplest possible way. You can access it with:

import eslint from '@putout/eslint';

To use it simply write:

const [source, places] = await eslint({
    name: 'hello.js',
    code: `const t = 'hi'\n`,
    fix: false,
});

Isn't it looks similar to 🐊Putout way? It definitely is! But... It has a couple differences you should remember:

• ☝️ 🐊Putout returns object with code and places properties.
• ☝️ ESLint has a name property that is used to calculate configuration file.

And you can even override any of ESLint ⚙️ options with help of config property:

const [source, places] = await eslint({
    name: 'hello.js',
    code: `const t = 'hi'\n`,
    fix: false,
    config: {
        extends: [
            'plugin:putout/recommended',
        ],
    },
});

If you want to apply 🐊Putout transformations using putout/putout ESLint rule, enable 🐊Putout with the same called flag lowercased:

const [source, places] = await eslint({
    name: 'hello.js',
    code: `const t = 'hi'\n`,
    fix: true,
    putout: true,
    config: {
        extends: [
            'plugin:putout/recommended',
        ],
    },
});

It is disabled by default, because ESLint always runs after 🐊Putout transformations, so there is no need to traverse tree again.
