@currents/commit-info

Collects Git commit info from git CLI

Install

Requires Node version 6 or above.

npm install --save @currents-dev/commit-info

Use

const {commitInfo} = require('@currents-dev/commit-info')
// default folder is current working directory
commitInfo(folder)
  .then(info => {
    // info object will have properties
    // branch
    // message
    // email
    // author
    // sha
    // timestamp (in seconds since epoch)
    // remote
  })

Notes:

• Code assumes there is .git folder and uses Git commands to get each property, like git show -s --pretty=%B, see src/git-api.js. Note: there is fallback to environment variables.
• Resolves with Bluebird promise.
• Only uses Git commands, see src/git-api.js
• If a command fails, returns null for each property
• If you need to debug, run with DEBUG=commit-info environment variable.

Fallback environment variables

If getting the commit information using git fails for some reason, you can provide the commit information by setting the environment variables. This module will look at the following environment variables as a fallback

branch: COMMIT_INFO_BRANCH
message: COMMIT_INFO_MESSAGE
email: COMMIT_INFO_EMAIL
author: COMMIT_INFO_AUTHOR
sha: COMMIT_INFO_SHA
timestamp: COMMIT_INFO_TIMESTAMP
remote: COMMIT_INFO_REMOTE

For Docker containers

When running your application inside a Docker container, you should set these environment variables using -e syntax.

$ docker run \
  -e COMMIT_INFO_BRANCH=develop \
  -e COMMIT_INFO_SHA=e5d9eb66474bc0b681da9240aa5a457fe17bc8f3 \
  <container name>

See docker-example for a full example.

Individual methods

In addition to commitInfo this module also exposes individual promise-returning methods getBranch, getMessage, getEmail, getAuthor, getSha, getTimestamp, getRemoteOrigin. These methods do NOT use fallback environment variables.

For example

const {getAuthor} = require('@currents/commit-info')
getAuthor('path/to/repo')
  .then(name => ...)

getBranch

Resolves with the current git branch name or null.

const {getBranch} = require('@currents/commit-info')
getBranch()
  .then(branch => ...)

• If this is detached commit (reporting HEAD), returns null
