Boost Your Next.js Workflow: Understanding npm run lint vs npm run build

Source: Dev.to

Introduction

Understanding the nuances of your tools can make a world of difference in a Next.js project. Two essential commands you’ll use frequently are npm run lint and npm run build.

npm run lint

npm run lint acts as your code’s best friend, ensuring everything is tidy and error‑free. It:

• Catches stylistic issues and potential bugs early.
• Enforces consistency across the codebase.
• Helps maintain overall code quality.

Running lint regularly prevents small problems from turning into larger headaches later in development.

npm run build

npm run build is the “dress rehearsal” for your application. It:

• Compiles your code for production.
• Checks for type errors (especially important when using TypeScript).
• Optimizes assets and bundles for optimal performance.

The build step ensures that the app runs smoothly for end users and that any runtime issues are caught before deployment.

Why Run Both Commands?

Running both lint and build provides a comprehensive safety net:

• Lint catches syntax, style, and potential logical errors early in the development cycle.
• Build validates that the compiled output works correctly and is optimized for production.

Together, they help you create a robust, maintainable, and high‑performance application.

Conclusion

Incorporating npm run lint and npm run build into your workflow is a best practice for any Next.js project. By doing so, you reduce bugs, improve code quality, and ensure your app performs at its best when it reaches users. Happy coding!
