babel-plugin-git-log-1

Babel plugin for inlining values from the last git commit.

Handy for embedding the relevant data from git into deployed web apps.

If you add

let git = require('babel-plugin-git-log-1')

the plugin transforms the line to:

let git = {
    ref: 'master',
    dirty: false,
    log: {
        hash: '0603a72934b829f7490447b8d241bb9278e9c05d',
        commiter: {
            name: 'Alexander Gromnitsky',
            email: 'alexander.gromnitsky@gmail.com',
            date: '2018-03-31T14:21:12+03:00'
        },
        subject: 'init',
        body: 'just a test'
    }
};

Setup

$ npm i babel-plugin-git-log-1

Use it via the cli:

babel --plugins babel-plugin-git-log-1 foo.js

By default, the plugin does its transformations only in the scope of modules, so this won't work:

function hello() {
    let git = require('babel-plugin-git-log-1)
}

To do the transformations everywhere, pass inner_scope option to the plugin via .babelrc:

{
    "plugins": [
        ["babel-plugin-git-log-1", {
            "inner_scope": true
        }]
    ]
}

By default, the plugin operates on HEAD. To use another commit object, use ref option.

Bugs

• Tested only w/ babel-cli 6.26.0 on Fedora 27.
• The plugin invokes git to grab the data, which is lame. The Right Way is to use nodegit (that uses libgit2), but I've seen people who scream when they see a native addon dependency, besides that a mere npm i nodegit yields 89MB node_modules dir.
