Including git commit hash and date in webpack build

Question

I\'m using react/es6/webpack. I want to show the date of the build and git hash somewhere in my app. What\'s the best approach?

Answer 1

You can use webpack's DefinePlugin:

// get git info from command line
let commitHash = require('child_process')
  .execSync('git rev-parse --short HEAD')
  .toString();

...
plugins: [
    new webpack.DefinePlugin({
      __COMMIT_HASH__: JSON.stringify(commitHash),
    })
  ]
...

Then you can use it in your app with __COMMIT_HASH__
