**THIS PROJECT IS UNDER DEVELOPMENT, DON'T USE IT ON PRODUCTION ENVIRONMENT.** After the [n0vad3v/webp_server](https://github.com/n0vad3v/webp_server), I decide to rewrite the whole program with Go, as there will be no more `npm install`s or `docker-compose`s. This is a Server based on Golang, 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.json`.. > 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](https://github.com/n0vad3v/webp_server) ### Size * `webp_server` with `node_modules`: 43M * `webp-server(go)` single binary: 15M ### Performance It's basically between `ExpressJS` and `Fiber`, much faster than the `http` package of course. ### Convenience * `webp_server`: Clone the repo -> `npm install` -> run with `pm2` * `webp-server(go)`: Download a single binary -> 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. Download the `webp-server` from [release](https://github.com/n0vad3v/webp_server_go/releases) page. 2. Create a `config.json` like [this](https://github.com/n0vad3v/webp_server_go/blob/master/config.json) to face your need, default convert quality is 80%. 3. Run the binary like this: `./webp-server --config /path/to/config.json`, use `screen` or `tmux` to hold it currently.(Will add systemd later) 4. Let Nginx to `proxy_pass http://localhost:3333/;` ## TODO - [x] 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. - [ ] A better way to supervise the program. - [ ] Get rid of render-blocking effect on first render. ## Build Install golang, enable go module, clone the repo, and then... ```shell script go build webp-server.go ``` **Due to the limitations of webp module, you can't cross compile this tool.**
