How to find or pick a suitable Chrome/Chromium revision number?

Question

I couldn't figure out a nice way to determine a suitable revision number to use with Puppeteer Sharp.

What I did was use the version lookup feature on the "OmahaProxy - Google Chrome" site. I looked-up the version of Chrome I'm running on my computer. [That seems like a reasonable starting point.] I assumed (guessed) that the "Branch Base Position" shown in the version info was a revision number.

I then opened the Chromium continuous builds archive and looked for a build for the revision around the revision number I found from the "OmahaProxy" site.

Is there a better way to find or pick a suitable revision number?

Answer 1

Puppeteer is always bundled with a specific revision of a specific version. I usually check the release information on Github where the expected Chromium version and revision is specified. For example:

v1.17.0

Big Changes

• Chromium 76.0.3803.0 (r662092)

Then to download the right one,

1. Go to Chromium browser snapshots

2. Choose the directory of your platform (e.g., Linux_x64)

3. Copy the revision number into the "Filter:" field without the "r" (e.g., 662092)

4. Download the .zip file you need.

Additional info

1. The URL template below can be just plugged in with the right information:

   https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=<platform>/<revision>/

   For example: https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Linux_x64/662092/

2. The most common issue on Linux is missing dependencies, and the Puppeteer "Troubleshooting" document specifies all the Linux dependencies. (See apt instructions for Ubuntu.)

3. curl needs -L when downloading on the console. See Stackoverflow thread.

4. When one is using puppeteer-core,

   you will then need to call puppeteer.connect(\[options\]) or puppeteer.launch(\[options\]) with an explicit executablePath option.

Puppeteer requires number which correspond Chromium browser build snapshot number. You can get the latest snapshot number here:

or you can view all available snapshots here:
