Set up ESLint for best practices

ESLint is a linter for JavaScript and TypeScript that enforces best practices, extending beyond type checking to catch potential bugs such as unused parameters or unawaited promises. The guide focuses on setting up ESLint for serverless functions, particularly with Convex, highlighting the importance of awaiting promises in server functions to ensure code execution. It discusses configuration options, such as using npm init @eslint/config to create a custom setup or adopting established best practices like Airbnb’s eslint-config-airbnb. Special attention is given to enforcing import rules to encourage the use of custom functions over raw server functions to maintain security and consistency, with tools like no-restricted-imports helping to manage imports effectively. The post also covers the integration of plugins like @typescript-eslint and eslint-plugin-react for enhanced functionality and rule enforcement, demonstrating how ESLint configurations can improve code quality and security in a React/Vite project using Convex.
