Understanding semver versioning for your nodejs packages

Semver is the standard way of updating the versions of your package in nodejs. After reading through the original article, I decided to put together a quick visual summary of it. Since its just a summary, it won't cover all of the topics, but its enough help you quickly wrap your head around it. The diagram below shows the different parts of a semver version number. parts of semver

When creating a package

PATCH Version Number
  • Starts from 1
  • Increments by 1 when you fix bugs but dont introduce new features.
MINOR Version Number
  • Starts from 0.
  • Indicates a backward compatible new feature.
  • An increment resets the patch number to 0 on each increment.
MAJOR Version Number
  • Starts from 0
  • Incremented only when a backwards incompatible feature is introduced.
  • An increments resets both - Minor and Patch version numbers to 0.
