Caching the asset discovery browser in CI

Learn how to cache the Percy CLI asset discovery browser in CI

This feature currently applies only when you use the Percy SDK on Percy Web projects.

Percy’s CLI (@percy/cli) downloads a specific browser (that we have tested & trust) for asset discovery. A Chromium browser is required for asset discovery. Normally this browser is installed once asset discovery is started.

You can automatically download this browser during the dependency install step (and cache those dependencies) by setting the following env var:

$ export PERCY_POSTINSTALL_BROWSER=true
