This package[1] is a replacement for the old phantomjs-integration[2] which is practically EOL. It is basically used to render PNGs of panels that triggered an alert in Grafana. This package internally uses `puppeteer`[3] to control a headless Chromium instance. Even though puppeteer recommends to use a fixed revision of `chromium`, I checked that our default `pkgs.chromium` works fine as well. Also, I don't think it's a good idea to use outdated browser versions[4]. I used the latest revision from `master` on purpose since compiling the code with `tsc` from `v2.0` didn't work and I couldn't figure out why.

# Notes for the upgrade:
|
|
# * Download the tarball of the new version to use.
|
|
# * Remove the `resolutions`-section from upstream `package.json`
|
|
# as this breaks with `yarn2nix`.
|
|
# * Regenerate `yarn.lock` and `yarn2nix`.
|
|
# * Replace new `package.json`, `yarn.nix`, `yarn.lock` here.
|
|
# * Update `version`+`hash` and rebuild.
