Jak porovnat requirements.txt a package.json

Dependency management je kritická část software development. Změny v requirements.txt nebo package.json mohou způsobit breaking changes security vulnerabilities nebo dependency conflicts.

Proč porovnávat dependency files

Version upgrades sledujte které libraries byly updated. Security patches identifikujte vulnerable dependencies. Dependency bloat detekujte unnecessary packages. Conflicts najděte incompatible version requirements. Audit trail dokumentujte proč dependencies byly přidány nebo odstraněny.

Requirements.txt pro Python

Plain text file s package names a versions. pip freeze generuje aktuální installed dependencies. Virtual environments izolují dependencies mezi projekty. Pinned versions exact version nebo version ranges. Transitive dependencies ne vždy explicitně listed.

Package.json pro JavaScript

JSON formát s dependencies devDependencies peerDependencies. npm install nebo yarn install podle lock file. Semantic versioning caret tilde ranges. Scripts section pro build test deploy commands. Nested dependencies v node_modules folder.

Porovnávání version changes

Major version bumps X.0.0 mohou obsahovat breaking changes. Minor version bumps 0.X.0 nové features backward compatible. Patch version bumps 0.0.X bug fixes. Lockfile changes package-lock.json nebo poetry.lock. Diff mezi dependency trees complete hierarchy.

Security vulnerability detection

npm audit nebo pip-audit pro scanning vulnerabilities. Dependabot nebo Renovate bot pro automated updates. Security advisories GitHub Security Alerts. CVE databases pro known vulnerabilities. Regular updates keep dependencies current.

Dependency conflicts

Multiple packages requiring different versions téhož dependency. Resolution strategies použijte compatible version ranges. Peer dependency warnings when versions don't match. Lock file conflicts při merge v Git. Testing po resolution changes.

Best practices

Pin critical dependencies pro stability. Use lock files pro reproducible builds. Regularly update dependencies security patches. Audit new dependencies před přidáním. Document why každá dependency je needed. Remove unused dependencies cleanup.

Tools pro dependency diff

pip-compile pro Python dependency resolution. npm list nebo yarn why pro dependency tree. Diff tools pro textové porovnání. Online services jako Libraries.io pro tracking updates. CI/CD integration automated checks v pipeline.

Efektivní dependency management minimalizuje security risks bugs a build failures across development lifecycle.
