If your GitHub Page is a project site, then the site will be deployed to a subfolder:
But on Netlify, the site will be deployed to the root:
Initially, I thought I needed to add a redirect or rewrite rule on Netlify.
But it turns out the solution is simpler than expected.
Instead of storing the site URL in
"homepage", I was able to store it in the environment variable
Both steps can be done by running the commands:
sed -i '' '/"homepage"/d' package.json echo PUBLIC_URL=/project/ >> .env
Now when you build for GitHub Pages, everything should still work as expected.
When you build for Netlify, you’ll need to set the environment variable
"" for it to work.
