lh-metrics-analysis

Tools to analyze trends in HTTP Archive's Lighthouse data.

This is not an officially supported Google product.

Setup

yarn
Enable BigQuery and set up a Google Cloud service account
Download a service account key
set GOOGLE_APPLICATION_CREDENTIALS to the key file's path for it to be used automatically

Testing

To be able to run the tests:

create a test_lh_extract dataset in your BigQuery project
make the service account from above at least a BigQuery Job User
give the service account BigQuery Data Editor access to just (or at least) the test_lh_extract dataset
consider limiting the BigQuery quota to the test account, just in case, though this may require creating a separate Cloud project used only for testing.

Service accounts should be given the minimum permissions needed. For more about the service account roles, see the BigQuery predefined roles docs.
