NPM Expert Q&A
How can I resolve npm version conflicts efficiently?
NPM Expert advises on identifying the conflicting packages using `npm list`, understanding the semantic versioning constraints causing the issue, and then updating your `package.json` to resolve conflicts either by adjusting version ranges or using `npm install <package>@<version>` to explicitly set versions.
What's the best way to manage global vs local npm packages?
Manage global packages (tools and utilities used across projects) using `npm install -g <package>` and local packages (project-specific dependencies) with `npm install <package>`. NPM Expert can guide you on when to use global installations and how to handle local dependencies effectively.
Can NPM Expert help optimize my project's package.json for production?
Yes, it offers advice on structuring your `package.json` for production, including defining precise dependencies, using `npm prune --production` to remove development-only packages, and leveraging `npm ci` for faster, more reliable builds.
How does NPM Expert assist with npm audit and security fixes?
It provides detailed steps on using `npm audit` to identify vulnerabilities, understanding the audit report, and applying recommended fixes or updates with `npm audit fix` to enhance project security.
What are the tips for effective npm package version management?
NPM Expert recommends using semantic versioning to manage package updates, understanding the `^`, `~`, and `>` version prefixes to control version ranges, and the importance of lock files (`package-lock.json` or `npm-shrinkwrap.json`) in ensuring consistent installations across environments.
