Comment utiliser : PWA Manifest Generator
- Enter the app name, a short name for the home screen (12 characters or fewer), a description and the start URL.
- Choose the display mode — standalone for an app-like window — and the theme and background colors used for the title bar and splash screen.
- Set where your icons live (192 and 512 px, plus a maskable one) and keep the offline service worker on, with the caching strategy that fits your site.
- Download the ZIP, put the files in your site root, add the
<head>tags and check Chrome DevTools → Application → Manifest.
What makes a site installable
- Served over HTTPS.
- A web app manifest with
nameorshort_name,start_url, adisplaymode other thanbrowser, and icons of at least 192 px and 512 px. - A linked manifest in the page’s
<head>. Chrome no longer requires a service worker to install, but you need one to work offline.
The service worker’s caching strategies
| Strategy | How it answers | Best for |
|---|---|---|
| Network first | Tries the network, falls back to the cache when offline | Pages (always used for HTML here) |
| Stale-while-revalidate | Answers from the cache instantly, updates the cache in the background | CSS, JS, images that change now and then |
| Cache first | Uses the cache and only goes to the network when missing | Files with a hash or version in the name |
Bump the cache version when you deploy, so the new service worker clears old caches on activation. When nothing is cached and the network is down, visitors see offline.html.
