Question 1

How to set up WebP detection on Nginx with this script?

Accepted Answer

Download the nginx.conf file from the project, run Nginx with that config using 'nginx -c /path-to/webp-detect/nginx.conf', and ensure WebP image files are pre-generated in the same directory as originals. The server will automatically serve WebP to supported browsers.

Question 2

WebP detect vs using a CDN like Cloudflare for image optimization – what's better?

Accepted Answer

WebP detect is a server-side solution for control over your infrastructure, while CDNs like Cloudflare offer managed optimization with less setup. Choose WebP detect if you need custom server configurations and avoid third-party dependencies; opt for a CDN for ease and scalability.

Question 3

Does WebP detect work with HTTP/2 or modern protocols?

Accepted Answer

Yes, since it relies on standard HTTP Accept headers and server configurations, it's compatible with HTTP/2 and other protocols. However, ensure your server setup supports these protocols without conflicts.

Question 4

What if my images are stored in a database, not on disk?

Accepted Answer

WebP detect won't work out-of-the-box; it requires WebP files on the filesystem. You'd need to modify the backend to generate and serve WebP dynamically or use a caching layer to store converted files.

Question 5

How to pre-generate WebP files for thousands of existing images?

Accepted Answer

Use tools like 'cwebp' from Google's WebP utilities or batch conversion scripts. Integrate this into your build process or use a separate service, as WebP detect doesn't handle conversion itself.

Question 6

Is WebP detection compatible with CDN caching and Vary headers?

Accepted Answer

Yes, it appends 'Vary: Accept' to responses, which is crucial for CDNs to cache different versions per browser. However, some CDNs might ignore or mishandle Vary headers, so test with your specific setup.
