Check if version is valid

$ semver [1.2.3]

$ semver -i major [1.2.3]

$ semver -i minor [1.2.3]

$ semver -i patch [1.2.3]

$ semver -r "[>=1.0.0 <2.0.0]" [1.5.0]

$ semver --coerce [v1.2]

$ semver [1.2.3] [1.0.0] [2.0.0]

semver [-i increment] [-r range] [options] version

semver validates and manipulates semantic version strings. It follows semver.org specification.
Version incrementing bumps major, minor, or patch. Prerelease versions add suffix.
Range matching tests version satisfaction. NPM-style ranges supported.
Coercion handles non-standard versions. Converts 1.2 to 1.2.0.
Sorting orders versions correctly. Higher versions sort later.

-i, --increment TYPE

Increment version.

Test against range.

Coerce to valid version.

Loose parsing.

Less than range.

Greater than range.

major - 1.2.3 -> 2.0.0
minor - 1.2.3 -> 1.3.0
patch - 1.2.3 -> 1.2.4
premajor - 1.2.3 -> 2.0.0-0
preminor - 1.2.3 -> 1.3.0-0
prepatch - 1.2.3 -> 1.2.4-0
prerelease - 1.2.3 -> 1.2.4-0

Node.js package. Strict mode may reject valid-looking versions. Range syntax can be complex.

semver is the Node.js implementation of semantic versioning. It's used by npm for package version resolution.
