About Emerge

Emerge offers a suite of products to help optimize app size, performance and quality. This plugin provides a set of actions to interact with the Emerge API.

Usage

To get started, first obtain an API token for your organization. The API Token is used to authenticate with the Emerge API in each call. Our actions will automatically pick up the API key if configured as an EMERGE_API_TOKEN environment variable.

Size Analysis

platform :ios do
  lane :app_size do
    # Make a signed release build via gym() and other tools
    # and then call our `emerge()` action to upload the artifact to our API
    emerge()
  end
end

For a full list of available parameters run fastlane action emerge.

Snapshot Testing

platform :ios do
  lane :snapshot_testing do
    # Call our `emerge_snapshot()` action with the respective scheme for
    # us to build. We will generate a build with the recommended settings
    # and upload to our API.
    emerge_snapshot(scheme: 'Hacker News')
  end
end

For a full list of available parameters run fastlane action emerge_snapshot.

Git Configuration

For build comparisons to work, Emerge needs the appropriate Git sha and base_sha values set on each build. Emerge will automatically compare a build at sha against the build we find matching the base_sha for a given application id. We also recommend setting pr_number, branch, and repo_name for the best experience.

For example:

• sha: pr-branch-commit-1
• base_sha: main-branch-commit-1
• pr_number: 42
• branch: my-awesome-feature
• repo_name: EmergeTools/hackernews

Will compare the size difference of your pull request changes.

This plugin will automatically configure Git values for you assuming certain Github workflow triggers:

on:
  # Produce base builds with a 'sha' when commits are pushed to the main branch
  push:
    branches: [main]

  # Produce branch comparison builds with `sha` and `base_sha` when commits are pushed
  # to open pull requests
  pull_request:
    branches: [main]

  ...

If this doesn't cover your use-case, manually set the sha and base_sha values when calling the Emerge plugin.
