|
|
# 1. We run webpack in a production like mode and enable the BundleAnalyzerPlugin
|
|
# 2. The Plugin builds a index.html for human consumption _and_ a stats.json
|
|
# 3. This script creates a smaller analysis.json from the gargantuan stats.json
|
|
# 4. In Merge Requests:
|
|
# - compare that smaller to analysis.json to the one from the base commit on master
|
|
# - report the comparison results via danger
|
|
|
