Ensure comprehensive dependency management in package.json files by following these practices:
Evaluate necessity: Before adding dependencies, check if native Node.js APIs provide the functionality. For example, use fs.mkdtemp(path.join(os.tmpdir(), 'prefix')) instead of adding a temporary file library.
Choose appropriate dependency types: Carefully classify dependencies as dependencies, devDependencies, or peerDependencies based on their usage. When uncertain about peer dependencies in monorepos, start with devDependencies and adjust as needed.
Use consistent versioning: Establish a clear strategy for version specifications - either pin exact versions ("esbuild": "0.25.0") or use ranges ("esbuild": "^0.25.0") consistently across the project.
Update all related files: When modifying package.json, ensure package-lock.json is also updated and included in commits.
Example of proper dependency evaluation:
// Instead of adding a dependency like 'tmp'
"dependencies": {
"tmp": "^0.2.3"
}
// Use native Node.js APIs
fs.mkdtemp(path.join(os.tmpdir(), 'myapp-'));
This approach reduces dependency bloat, minimizes security vulnerabilities, and maintains cleaner, more maintainable projects.
