SemVer satisfies

semver-satisfies · version 1.0.0 · Versions & config · free, no key needed

Test whether a strict version satisfies a semver range.

Use when you need to: semver satisfies · version satisfies range · semver range test.

Supported

• semver satisfies
• version satisfies range
• semver range test

Not supported

• loose
• git urls
• npm tags
• latest

Behavior

• version must be a strict SemVer as above.
• range is a string passed to semver.satisfies(version, range, { includePrerelease: include_prerelease === true, loose: false }).
• Supported range syntax is what semver 7.8.5 accepts in non-loose mode: comparators, hyphen ranges, X-ranges, tilde, caret, ||.
• If the range is empty or semver.invalid as a range, reject. Do not throw raw package errors; map to invalid_input.
• include_prerelease defaults false. Unknown fields rejected.

Input

• version (string, required): min length 1; max length 256
• range (string, required): min length 1; max length 512
• include_prerelease (boolean, optional)

Output

• satisfies (boolean, required)

Limits

• max version length: 256
• max range length: 512

Example

Request input:

{
  "version": "1.2.3",
  "range": "^1.0.0"
}

Response:

{
  "result": {
    "satisfies": true
  }
}
