Bump 🍑

Automate new releases for node.js projects on the command line.

A new release is defined as:

1. An incremental increase to the version property in the package.json and package-lock.json files.
2. A commit of the two json files with a descriptive message about the reason for the version bump.
3. The optional creation of a tag with a descriptive message.

Install

npm install --global @bzelip/bump

This will install bump globally so that it can be run from the command line.

Use

There are two main commands:

1. bump <strategy> <message>
2. bump undo

bump

Bump your version based on a strategy, and include a description of the reason for the bump in the generated commit message.

bump <strategy> <message>

• major

• minor

• patch

Example

Input

# current version 0.4.0

bump minor "create custom slider"

Output

🍑: Successfully minor bumped version to 0.5.0 with the commit message:

"package*: v0.5.0 Bump minor for create custom slider 🎉"

Note bump does not push, it only commits locally.

undo

Undo a bump.

bump undo

This command is an alias for running:

git reset HEAD~

git checkout -- package*

Note Be sure to only use bump undo immediately after bump <strategy> <message> to have the desired action.

Assumptions

• your project is git tracked
• you are following Semantic Versioning
• your current working directory includes both package.json and package-lock.json files

TODO

• [ ] add the create tag with message option
• [ ] add tests

My release protocol

My current release protocol includes:

• git
• a Semantic Versioning approach
• a changelog.md
• once a feature branch's work is finalized and documented in changelog.md:
  1. open package.json, bump the version accordingly
  2. open package-lock.json, bump the version accordingly
  3. commit with message of the form package*: v${version} ${strategy} bump for ${message} 🎉
  4. TODO: create new tag with command of the form: tag v${version} -m ${message}
  5. push to remote, and start the PR process (do this manually after bump.js)
  6. push new tag to remote (do this manually after bump.js)
