The site.webmanifest needs a mandatory start_url

[andrecasal]

As per MDN docs, the site.webmanifest requires a start_url so the website becomes installable.

I suggest adding "start_url": "http://localhost:3000", so users can test app installation during development.

What if we move the site.webmanifest to be a resource route so the start_url can be dynamic based on the domain? That way people don't have to worry about keeping it up-to-date and it'll work for preview deploys and staging etc.

Great idea! 👍

Actually, looking at this it appears a relative URL would suffice. Maybe we can set it to ./?

Let me try that out... It works 💪
