❓ Frequently Asked Questions
How do I install an npm package? ▾
Run npm install package-name in your project directory. Add --save-dev for development-only dependencies. Use yarn add or pnpm add for those package managers.
What is the difference between dependencies and devDependencies? ▾
dependencies are required at runtime (express, react). devDependencies are only needed during development (jest, eslint, typescript). Use --save-dev for dev packages.
How do I check for outdated packages? ▾
Run npm outdated in your project directory to see all outdated packages with current, wanted and latest versions. Then run npm update to update within semver constraints.
