👀 How to use

1. Install the dependency

2. Add it to your .eslintrc.js file:

   {
     extends: [ "eslint-config-codely" ]
   }
   

3. If you are using TypeScript, extend the TypeScript configuration instead, and point to your tsconfig.json in parserOptions:

   {
     extends: [ "eslint-config-codely/typescript" ],
     overrides: [
       {
         files: ["*.ts", "*.tsx"],
         parserOptions: {
           project: ["./tsconfig.json"],
         },
       },
     ]
   }
   

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