What is Semantic Versioning?
Semantic Versioning uses the format major.minor.patch:
- MAJOR version for incompatible API changes
- MINOR version for added backward-compatible functionality
- PATCH version for backward-compatible bug fixes
How npm Uses Semantic Versioning
In package.json, dependency ranges control allowed updates:
- Patch-level:
"~1.2.3"or"1.2.x"→ versions≥1.2.3 <1.3.0 - Minor-level:
"^1.2.3"or"1.x"→ versions<2.0.0 - Major-level:
"*"or"x"→ any version
