semver Comparator
Compare two semantic versions and interpret version range notation.
Category: Dev Tools
When to use?
Use it to check the version difference before/after a package update, or to quickly see whether a version falls in a ^ range.
How to use
- Enter the two versions to compare.
- Enter the range expression.
- Check the comparison and inclusion.
Input Explanation
Enter semantic versions like x.y.z and a ^x.y.z range.
Calculation Basis
It separates major, minor, and patch numbers to compare in order, and a caret range checks whether a version is at or above the base within the same major.
Usage Examples
- Decide package updates - Check whether an update version falls in the current range.
- Compare version sizes - Compare which version is newer in major·minor·patch order.
- Check dependency ranges - Check whether a version is in a ^ range to judge compatibility.
Examples
- 1.4.2 vs 1.5.0 → 1.5.0 is larger
- Check whether 1.5.0 is in the ^1.2.3 range
Cautions
- Generated output is for reference; test carefully before production use.
- It focuses on basic comparison and simple caret (^) range checks.
FAQ
Are all npm range syntaxes supported?
The UI focuses on basic comparison and simple caret (^) range checks.
In what order are versions compared?
Major first, then minor, then patch when equal.
How far does the caret (^) range allow?
^1.2.3 allows 1.2.3 or higher within the same major (1.x.x); a higher major is out of range.
Which is larger, 1.0.0 or 1.0.0-beta?
By semver, a release is larger than a prerelease, so 1.0.0 is newer than 1.0.0-beta.
