git-describeify

git-describeify

This browserify transform calls git-describe with the provided arguments on the working directory or any other directory and parses the output to individual components. On build/transform time the git-describe information will be injected so that it can be used in, for example, browser served applications which have no access to the local file system.

Installation

Available from npm:

$ npm i git-describeify

Tests are not included in the npm package — clone the git repository to run tests.

Usage

git-describeify uses the node git-describe module. During transform, require('git-describeify') is replaced with the git-describe object.

Browserify transform

Make sure to enable the transform in Browserify by either specifying it in the terminal

$ browserify -t git-describeify

or by putting it in the package.json.

{
  "browserify": {
    "transform": [
      "git-describeify"
    ]
  }
}

Require syntax

//       Require the module        the arguments passed to git-describe
require('git-describeify', argument1, argument2, argument3, ...);

// For example
const gitInfo = require('git-describeify');

// Transforms into:
const gitInfo = {
    dirty: false,
    hash: 'g3c9c15b',
    distance: 6,
    tag: 'v2.1.0-beta',
    semver: SemVer, // SemVer instance, see https://github.com/npm/node-semver
    suffix: '6-g3c9c15b',
    raw: 'v2.1.0-beta-6-g3c9c15b',
    semverString: '2.1.0-beta+6.g3c9c15b'
}

More examples

// Target working directory
const gitInfo = require('git-describeify');

// Target the directory of the calling script
// Recommended when you want to target the repo your app resides in
const gitInfo = require('git-describeify', __dirname);

// With options (see https://www.npmjs.com/package/git-describe)
const gitInfo = require('git-describeify', __dirname, {
    longSemver: true,
    dirtySemver: false
});

// Another example: working directory, use 16 character commit hash abbreviation
const gitInfo = require('git-describeify', {
    customArguments: ['--abbrev=16']
});

Example output

{
    dirty: false,
    hash: 'g3c9c15b',

    suffix: '6-g3c9c15b',
    raw: 'v2.1.0-beta-6-g3c9c15b',
