Building a Workflow to Optimize Changed SVG Files
A GitHub Actions workflow triggered on pull requests can detect which SVG files changed, run SVGO against just those files, and either fail the check if unoptimized SVGs are detected or automatically commit the optimized versions back to the pull request branch, keeping icon file size consistent without relying on every contributor remembering to optimize manually.
- Workflow detects and processes only the SVG files changed in a pull request
- Can fail the check on unoptimized files or auto-commit optimized versions
- Keeps icon file size consistent without relying on manual contributor discipline
Adding Validation Alongside Optimization
Beyond just running SVGO, the same workflow can validate that new SVG files include appropriate accessibility attributes, don't exceed a maximum file size, and parse correctly, catching common SVG quality issues automatically during code review rather than after the icon has already shipped to production.
- Can validate accessibility attributes and enforce a maximum file size
- Catches common SVG quality issues automatically during code review
- Prevents problematic icon files from reaching production undetected
Frequently Asked Questions
Will an automated workflow slow down every pull request significantly?
Scoping the workflow to run only when SVG files actually changed, using a path filter in the workflow trigger, keeps it fast and avoids adding unnecessary time to pull requests that don't touch any SVG files.
Can the workflow automatically commit optimized files back to the PR?
Yes, using a bot commit step with appropriate repository permissions, the workflow can push optimized SVG files directly back to the contributor's pull request branch automatically.
