npm-snapshot

A little script to help with prerelease npm modules.

Usage

You must use npm-snapshot in a folder with a package.json.

npm-snapshot 245

The argument to this utility is a unique, monotonically increasing number (say, a build number from Travis or Shippable) that will be appended to the prerelease portion of the existing version. If there is no current prerelease portion of the version, the string 'SNAPSHOT' will be used. Any existing prerelease portion will be preserved, up to the first '.'.

For example, given the version "1.2.4", calling

npm-snapshot 245

will change the package.json to be "1.2.4-SNAPSHOT.245".

Additionally, the prerelease prefix is emitted on standard out. This is useful as a tag when publishing. For example:

BUILD_TAG = $(npm-snapshot $BUILD_NUMBER)
npm publish --tag BUILD_TAG

Install

npm install -g npm-snapshot
