BundleWatch

BundleWatch checks file sizes, ensuring bundled browser assets don't jump in file size.
Sharp increases in BundleWatch can signal that something is wrong - adding a package that bloats the slug, a wrong import, or forgetting to minify.

Inspired by Siddharth Kshetrapal bundlesize

Getting Started:

Install the BundleWatch package:

• NPM: npm install bundlewatch --save-dev
• Yarn: yarn add bundlewatch --dev

Add some basic configuration to your package.json

{
    "name": "my package name",
    "version": "0.0.1",
    "bundlewatch" : {
        "files": [
            {
                "path": "myfolder/*.js",
                "maxSize": "100kB"
            }
        ]
    }
}

Usage:

• NPM: npm run bundlewatch
• Yarn: yarn run bundlewatch

This will give you command line output. If you want BundleWatch to report build status on your pull requests, see below.

Adding Build Status:

BundleWatch can report its status on your GitHub Pull Requests.

CI Auth Variables Needed by BundleWatch:

• BUNDLEWATCH_GITHUB_TOKEN

You will need to give BundleWatch access to your GitHub Statuses, which can be done by heading to: https://service.bundlewatch.io/setup-github

This will give you your BUNDLEWATCH_GITHUB_TOKEN. You will need to set this as an environment variable in CI.

CI Variables Needed by BundleWatch:

The most efficient way to get this running is to ensure that some environment variables are available for BundleWatch to find.

• CI_REPO_OWNER github.com/facebook/react
• CI_REPO_NAME github.com/facebook/react
• CI_COMMIT_SHA
• CI_BRANCH

If you're using, Travis, CircleCI, Wrecker or Drone these should all work out of the box.

Have a look at the source code to see which variables are automatically found: https://github.com/bundlewatch/bundlewatch/blob/master/src/app/config/getCIVars.js

Viewing the results breakdown

After setting up the above you will have BuildStatus on your Pull Requests. Clicking the details link on the reported status will show you a results file breakdown.

I use bundlesize, why should I switch to BundleWatch?

• Bundlesize has entered maintenance mode and pull requests are left hanging, so we wanted to reboot the community through creating BundleWatch
• New BundleWatch service with infrastructure as code
• Launched bundlewatch.io documentation website
• Enough test coverage to support CD
• Node API Support
• Lower barrier to contributing (automated testing and publishing), build a trusted community of contributors to have continuous improvement

Additional Features:

• Config validation to stop users from guessing why BundleWatch won't work
• Support for config file path
• Better results breakdown page
• Better comparisons between branches, support branches other than master
• Support for your own server for storing data
• New and improved CI behaviour
• Show history of BundleWatchs over time (coming soon)
