chrome-versions

Self updating repository to store Google Chrome release and version info as JSON.

Windows	macOS	Linux	Android

TL;DR

Use a CDN to fetch the data as needed, examples:

• Latest chrome stable version info for all platforms:
  • https://cdn.jsdelivr.net/gh/berstend/chrome-versions/data/stable/all/version/latest.json
• Last 15 chrome stable versions for all platforms:
  • https://cdn.jsdelivr.net/gh/berstend/chrome-versions/data/stable/all/version/list.json
• Latest chrome stable version for windows:
  • https://cdn.jsdelivr.net/gh/berstend/chrome-versions/data/stable/windows/version/latest.json
• Extended release info for the last chrome stable windows release:
  • https://cdn.jsdelivr.net/gh/berstend/chrome-versions/data/stable/windows/info/latest.json

Data

The ./data directory contains the JSON files:

• The data is split by the two main release channels (dev and stable)
• The data is split by the platform (windows, mac, linux, android)
• In addition combined version info for all platforms is provided under all

Info

• Contains the full release info, either as latest.json or list.json

Version

• Contains brief version info, either as latest.json or list.json

Trigger your own Github workflow on new chrome versions

Unfortunately Github Actions has no broadcasting feature and this repo can only dispatch to manually defined repos.

As a workaround you can add a new workflow that will poll the JSON file relevant to you recurringly (using a cron trigger), hash the data and use Github's built-in caching feature to understand if a change happened and your other workflow should be triggered.

Note:

• The workflow below is very quick and checking if new versions are available takes only a few seconds
• Githubs removes cache entries not accessed in 7 days, which is not a problem given this workflow runs more often
• The first time the workflow is triggered it has not cached the hash of the chrome versions yet and will trigger the target workflow

Prerequisites:

• Your target workflow needs a workflow_call trigger:

on:
  workflow_call:

Poll for changes using cron

Save the below workflow as .github/workflows/check-chrome-versions.yml in you repo:

name: "[cron] Check chrome versions"

on:
  workflow_dispatch:
  schedule:
    - cron: "0 * * * *" # https://crontab.guru/every-1-hour

jobs:
  check-versions:
    runs-on: ubuntu-latest
    outputs:
      cache-hit: ${{ steps.cache.outputs.cache-hit }}
    env:
      # You can use any JSON file here
      CHROME_VERSION_URL: "https://cdn.jsdelivr.net/gh/berstend/chrome-versions/data/stable/all/version/latest.json"

    steps:
      - name: Get hash of chrome versions
        id: get-versions
        run: |
          json=$(curl -s ${{ env.CHROME_VERSION_URL }})
          echo json: ${json}
          hash=$(echo -n $json | md5sum)
          echo hash: ${hash}
          echo "::set-output name=hash::$hash"
        shell: bash

      - name: Setup cache based on hash
        id: cache
        uses: actions/cache@v3
        with:
          path: ~/cache-chrome-version # no-op
          key: chrome-${{ steps.get-versions.outputs.hash }}

      - name: "Cache hit: Exit"
        if: steps.cache.outputs.cache-hit == 'true'
        run: echo "cache hit, no new chrome versions"

  trigger-workflow:
    if: needs.check-versions.outputs.cache-hit != 'true'
    needs: check-versions
    uses: ./.github/workflows/build.yml # Change this to your target workflow

Change ./.github/workflows/build.yml to whatever workflow you want to trigger on new chrome versions.

Troubleshooting:

• Permission errors: Workflows inherit their permissions from the parent, if you set special permissions in your target workflow you need to define them in the above one as well
• "(...) doing so would exceed the limit on called workflow depth of 2" error: Github unfortunately doesn't allow reusable workflows to call reusable workflows
