THIS PROJECT IS UNDER DEVELOPMENT, DON'T USE IT ON PRODUCTION ENVIRONMENT.

After the n0vad3v/webp_server, I decide to rewrite the whole program with Go, as there will be no more npm installs or docker-composes.

This is a Server based on Go and a precompiled cwebp(libwebp-1.1.0-rc2-linux-x86-64), which allows you to serve WebP images on the fly, it will convert jpg,jpeg,png files by default, this can be customized by editing the config.js..

e.g When you visit https://a.com/1.jpg，it will serve as image/webp without changing the URL.

For Safari and Opera users, the original image will be used.

Compare to n0vad3v/webp_server

Size

• webp_server with node_modules: 43M
• webp_server_go single binary: 9.5M

Performance

It's basically between ExpressJS and Fiber, much faster than the http package of course.

Convenience

• webp_server: Clone -> npm install -> run with pm2
• webp_server_go: Download -> Run

Usage

Regarding the IMG_PATH section in config.json, if you are serving images at https://example.com/pics/tsuki.jpg and your files are at /var/www/image/pics/tsuki.jpg, then IMG_PATH shall be /var/www/image.

1. Edit the config.json to face your need, default convert quality is 80%.
2. Run the binary like this: ./webp_server, use screen or tmux to hold it currently.
3. Let Nginx to proxy_pass http://localhost:3333/;

TODO

• This version doesn't support header-based-output, which means Safari users will not see the converted webp images, this should be fixed in later releases.
• Multi platform support.
