🤏 Codely's ESLint + Prettier configuration

Opinionated linting configuration considering modern TypeScript best practices and providing consistency to your import statements. Valid for your JavaScript or TypeScript projects 🤟

Take a look, play and have fun with this. Stars are welcome 😊

👀 How to use

1. Install the dependency.

npm install --save-dev eslint-config-codely

2. Add it to your eslint.config.js:

import eslintConfigCodely from "eslint-config-codely";

export default [
    // If you're using js
    ...eslintConfigCodely.js,
    // Or if you're using ts. The ts config includes the js one, so you don't need to include it manually.
    ...eslintConfigCodely.ts,
    {
        // Your config here
    }
]

Also, you can use the full config, which includes the js, ts and very opinionated Codely configs.

import eslintConfigCodely from "eslint-config-codely";

export default [
    ...eslintConfigCodely.full,
    {
        // Your config here
    }
]

We have a course setting. This is the same as the full config, but with a narrower width due to the zoom used in videos:

import eslintConfigCodely from "eslint-config-codely";

export default [
    ...eslintConfigCodely.course,
    {
        // Your config here
    }
]

ℹ️ Please note that some of the rules enabled by default require that you have strict: true in your tsconfig.json.
