NPM Auto Version

This script is used to automatically generate new NPM versions based on Git tags when publishing.

Usage

Recommended contents of your package.json:

{
    "version": "1.0.0",
    "scripts": {
        "prepublish": "npm-auto-version",
        "postpublish": "git push origin --tags"
    }
}

This will (under the hood) do the following when you run npm publish:

• Get the MAJOR.MINOR version from your package.json version field (call them M and N respectively)
• Get the list of git tags that match M.N.*
• Use semver to generate the next appropriate patch value M.N.P
• Update the package.json version field with M.N.P
• Generate a new git tag in the NPM syntax: vM.N.P
• Publish the package to NPM (via npm publish)
• Push the tags to your git origin

Requirements

This script requires:

• Node 0.12+
• Git client and grep installed in $PATH
• Shell that supports pipe |
