[QUESTION] includePrerelease usage

[bz888]

Hey, just wondering how do you use the prerelease tag in validRange e.g. const validated = valid('1.2.0-19', { includePrerelease: true})

With my understanding of includePrerelease this would result to null. However, currently it returns 1.2.0-19 Is there perhaps another more suited method I should be looking at?

Thank you in advance~

Why would that be invalid? It's a range of one.

[bz888]

Is there a build-in method that checks for the -19 part ? If there is a -19 returns invalid

[bz888]

Sorry, I mistyped. I was meant to say includePrerelease: false

[ljharb]

A range won’t implicitly include prereleases when that option is set to false, but that is an exact version. This behavior seems correct to me.

[bz888]

Is there perhaps another way to identify an prerelease using semver ?

[ljharb]

Are you looking for the prerelease function?

[bz888]

Something similar I guess. But mainly looking for if i can accomplish these conditions with one function: 1.2.0-20 or ^1.2.0-20 fail (any version that supports pre release would fail) >=1.2.20 pass * pass 1.2.0 pass

or would I have to layer a bunch of semver functions together to accomplish this ?

[ljharb]

prerelease(version) === null tells you exactly that.

Oh ! thank you so much!
