How to Match Semantic Version Numbers with Regex
When working with software versions like 1.0.2 or 3.45.12-SNAPSHOT, it's common to use regular expressions (regex) to validate or extract these patterns. This Snipp shows you a simple and effective way to match such version numbers using regex.
What We Want to Match:
1.0.23.32.343.45.12-SNAPSHOT
These are typical semantic version numbers and may optionally include a suffix like -SNAPSHOT.
The Regex:
^\d+\.\d+\.\d+(?:-SNAPSHOT)?$How It Works:
^— Start of the string\d+— One or more digits (major, minor, patch)\.— Dots separating version parts(?:-SNAPSHOT)?— Optional suffix (non-capturing group)$— End of the string
Matches:
- ✔️
1.0.2 - ✔️
3.32.34 - ✔️
3.45.12-SNAPSHOT
Not Matched:
- ❌
1.0 - ❌
3.2.4-RELEASE - ❌
a.b.c
This pattern is useful when validating software version inputs in forms, logs, or build scripts.
