node-release-utils

Tools for incrementing versions and tagging node.js projects in Git.

Simple scripts for incrementing the version of your project, automatically tagging, and releasing.

Releasing can be to the global npm repo or to an S3 bucket (which is useful for deploying closed-source npm modules)

Installation

Add to your project using npm. E.g.

npm install node-release-utils

However it's better to add the project as a dev-dependency in your package.json. See the examples for more information.

Examples

Using release-utils in a publishable npm project

npm is a great tool for publishing a project. You just run npm publish and your package is available on the web. Npm will stop you releasing multiple packages with the same version (although it is possible to force it to overwrite an existing release).

This is all excellent, but using npm publish requires you to increment your version numbers. It also doesn't force you to create an scm-tag for every release.

If you're using npm and git, then release-utils can help. Just add the project as a dev-dependency and call the npm-release script. This script will do the following:

• Create an scm tag
• Increment the version in package.json
• Checkout the tag, package, and publish the module (it delegates to npm publish)
• Push the tag to an upstream repo (e.g. GitHub)

The configuration is minimal. In package.json add the dependency and a new script definition:

    "devDependencies": {
        "release-utils": ">= 0.0.1"
    }
    ...
    "scripts": {
        "build-release": "node node_modules/release-utils/npm-release.js",
    }

Then to do a release, run:

npm run-script build-release

Using release-utils in a private project

Maybe your project is secret and you don't want to deploy it to the global npm repo? Npm has some great features to build a tarball of your code, but again (see above), you'll want to automate the tagging and incrementing of your software's version. The release-utils project has support for uploading your *.tgz package to an Amazon S3 bucket.

A release will do the following:

• Create an scm tag
• Increment the version in package.json
• Checkout the tag, package, and build a package (it delegates to npm pack)
• Upload the new package to S3
• Push the tag to an upstream repo (e.g. GitHub)

To configure an S3 release, add the release-utils project as a dev dependency and reference the s3-release script in your package.json. E.g.

    "devDependencies": {
        "release-utils": ">= 0.0.1"
    }
    ...
    "scripts": {
        "build-release": "node node_modules/release-utils/s3-release.js MYBUCKET",
    }

You'll need your AWS credentials in the following environment variables:

AWS_ACCESS_KEY
AWS_SECRET_ACCESS_KEY

Then, to do a release, run:

npm run-script build-release
