Automated lint tools can help developers save time and keep everybody on the same page. When everybody on your team follows the same rules, you don’t have to waste time discussing code style issues. These tools can catch a lot of syntax and type errors.

Combining ESLint with Prettier is a nice way to perform both automated syntax scans on your code and reformatting. This will ensure that consistent rules are being followed for indentation, spacing, semicolons, etc.

Let’s set up these technologies to use them in a Next.js project that uses TypeScript. If you are starting a new project, you can read my article about how to set up Next.js with TypeScript.

ESLint

Let’s start by adding the core ESLint linting library, the parser to lint TypeScript code, a TypeScript-specific plug-in, and a React-specific plug-in to our project.
