Diffing Against Branches Other Than Master

By default, after following the Using Bundlewatch guide, Bundlewatch will diff your bundles against the master branch.

If you want to diff against another branch (e.g. develop), set the following CI environment variable:

• CI_BRANCH_BASE

If you're using Travis or Drone, this is usually set automatically.

Info

See which CI variables are automatically detected in the getCIVars.js source code.

To diff against multiple branches (e.g. develop, staging), add the trackBranches option to your Bundlewatch config in package.json:

{
  "bundlewatch": {
    "files": [
      {
        "path": "myfolder/*.js",
        "maxSize": "100kB"
      }
    ],
    "ci": {
      "trackBranches": ["master", "develop", "staging"]
    }
  }
}

For more configuration options, see the Configuration Reference.
