# 自定义webp-server-go
|
||
|
||
1. 如果文件非图片类型, 302重定向到源文件
|
||
2. 改进对比逻辑, 不仅仅依靠etag
|
||
主要修改：
|
||
增加了文件大小和最后修改时间的检查。
|
||
保留了原有的 ETag 对比逻辑。
|
||
使用多重条件判断文件是否需要更新。
|
||
主要好处：
|
||
|
||
提高了文件变更检测的准确性：
|
||
|
||
不仅依赖 ETag，还考虑了文件大小和修改时间。
|
||
能够捕获一些 ETag 未能反映的变化。
|
||
保持了效率：
|
||
|
||
优先使用缓存的 ETag，减少不必要的网络请求。
|
||
只有在确实需要时才进行文件下载。
|
||
增强了适应性：
|
||
|
||
即使某些信息（如 ETag）不可用，也能依靠其他指标进行判断。
|
||
改进了日志记录：
|
||
|
||
提供更详细的信息，说明为什么文件需要更新。
|
||
总的来说，这些修改在保持原有功能的基础上，提高了文件更新检测的准确性和鲁棒性，同时保持了系统的效率。
|
||
3. 低于100KB的文件不处理
|
||
4. 优化日志可读性
|
||
5. 内存优化:
|
||
* 控制并发
|
||
* 流式处理大文件
|
||
* 使用流式JSON编码器
|
||
* 内存使用监控
|
||
6. 根目录设置打招呼
|
||
7. 移除`IMG_PATH`的配置方式, 只保留`IMG_MAP`.
|
||
8. 当前缀与`IMG_MAP`不匹配时, 直接返回错误

|
||
|
||
This is a Server based on Golang, which allows you to serve WebP images on the fly.
|
||
|
||
Currently supported image format: JPEG, PNG, BMP, GIF, SVG, HEIC, NEF, WEBP
|
||
|
||
> e.g When you visit `https://your.website/pics/tsuki.jpg`，it will serve as `image/webp`/`image/avif` format without changing the URL.
|
||
>
|
||
> GIF image will not be converted to AVIF format because the converted AVIF image is not animated.
|
||
|
||
## Usage with Docker(recommended)
|
||
|
||
We strongly recommend using Docker to run WebP Server Go because running it directly with the binary may encounter issues with `glibc` and some dependency libraries, which can be quite tricky to resolve.
|
||
|
||
Make sure you've got Docker and `docker-compose` installed, create a directory and create `docker-compose.yml` file inside it like this:
|
||
|
||
```yml
|
||
|
||
services:
|
||
webp:
|
||
image: woodchen/webp-server-go
|
||
restart: always
|
||
volumes:
|
||
- ./path/to/pics:/opt/pics
|
||
- ./exhaust:/opt/exhaust
|
||
- ./metadata:/opt/metadata
|
||
ports:
|
||
- 127.0.0.1:3333:3333
|
||
```
|
||
|
||
Suppose your website and image has the following pattern.
|
||
|
||
| Image Path | Website Path |
|
||
| ------------------------------------- | ------------------------------------ |
|
||
| `/var/www/img.webp.sh/path/tsuki.jpg` | `https://img.webp.sh/path/tsuki.jpg` |
|
||
|
||
Then
|
||
|
||
* `./path/to/pics` should be changed to `/var/www/img.webp.sh`
|
||
* `./exhaust` is cache folder for output images, by default it will be in `exhaust` directory alongside with `docker-compose.yml` file, if you'd like to keep cached images in another folder, you can change `./exhaust` to `/some/other/path/to/exhaust`
|
||
* `./metadata` is cache folder for images' metadata, by default it will be in `metadata` directory alongside with `docker-compose.yml` file
|
||
|
||
Start the container using:
|
||
|
||
```
|
||
docker-compose up -d
|
||
```
|
||
|
||
Now the server should be running on `127.0.0.1:3333`, visiting `http://127.0.0.1:3333/path/tsuki.jpg` will see the optimized version of `/var/www/img.webp.sh/path/tsuki.jpg`, you can now add reverse proxy to make it public, for example, let Nginx to `proxy_pass http://127.0.0.1:3333/;`, and your WebP Server is on-the-fly!
|
||
|
||
## Custom config
|
||
|
||
If you'd like to use a customized `config.json`, you can follow the steps in [Configuration | WebP Server Documentation](https://docs.webp.sh/usage/configuration/) to genereate one, and mount it into the container's `/etc/config.json`, example `docker-compose.yml` as follows:
|
||
|
||
```yml
|
||
version: '3'
|
||
|
||
services:
|
||
webp:
|
||
image: webpsh/webp-server-go
|
||
# image: ghcr.io/webp-sh/webp_server_go
|
||
restart: always
|
||
volumes:
|
||
- ./path/to/pics:/opt/pics
|
||
- ./path/to/exhaust:/opt/exhaust
|
||
- ./path/to/metadata:/opt/metadata
|
||
- ./config.json:/etc/config.json
|
||
ports:
|
||
- 127.0.0.1:3333:3333
|
||
```
|
||
|
||
You can refer to [Configuration | WebP Server Documentation](https://docs.webp.sh/usage/configuration/) for more info, such as custom config, AVIF support etc.
|
||
|
||
## Advanced Usage
|
||
|
||
If you'd like to use with binary, please consult to [Use with Binary(Advanced) | WebP Server Documentation](https://docs.webp.sh/usage/usage-with-binary/)
|
||
|
||
> spoiler alert: you may encounter issues with `glibc` and some dependency libraries.
|
||
|
||
For `supervisor` or detailed Nginx configuration, please read our documentation at [https://docs.webp.sh/](https://docs.webp.sh/)
|
||
|
||
## WebP Cloud Services
|
||
|
||
We are currently building a new service called [WebP Cloud Services](https://webp.se/), it now has three parts:
|
||
|
||
* [Public Service](https://public.webp.se)
|
||
* GitHub Avatar/Gravater reverse proxy with WebP optimization, for example, change `https://www.gravatar.com/avatar/09eba3a443a7ea91cf818f6b27607d66` to `https://gravatar.webp.se/avatar/09eba3a443a7ea91cf818f6b27607d66` for rendering will get a smaller version of gravater, making your website faster
|
||
* Totally free service and currently has a large number of users, this includes, but is not limited to [CNX Software](https://www.cnx-software.com/), [Indienova](https://indienova.com/en)
|
||
* [WebP Cloud](https://docs.webp.se/webp-cloud/)
|
||
* No need to install WebP Server Go yourself, especially suitable for static websites.
|
||
* Image Conversion: WebP Cloud converts images to WebP/AVIF format, reducing size while maintaining quality for faster website loading.
|
||
* Example 1: Original image URL (https://yyets.dmesg.app/api/user/avatar/BennyThink) becomes compressed URL (https://vz4w427.webp.ee/api/user/avatar/Benny).
|
||
* Example 2: Original image URL (https://yyets.dmesg.app/api/user/avatar/BennyThink) becomes a thumbnail image using URL (https://vz4w427.webp.ee/api/user/avatar/BennyThink?width=200).
|
||
* Caching: WebP Cloud automatically caches served images, reducing traffic and bandwidth load on the origin server.
|
||
* [Fly](https://webp.se/fly/)
|
||
* We call this service Fly, with the aim of providing a public and free service that users can experience without registering on WebP Cloud.
|
||
As this is a public service, some limitations compared to WebP Cloud are imposed:
|
||
|
||
- Fly supports a maximum original image size of 8MB, while WebP Cloud supports up to 80MB.
|
||
- Fly cache time is 1 day, while WebP Cloud has unlimited time (can be manually cleared at any time).
|
||
- It does not support parameters like `blur`, `sharpen` for image processing.
|
||
- And that’s it.
|
||
|
||
For detailed information, please visit [WebP Cloud Services Website](https://webp.se/) or [WebP Cloud Services Docs](https://docs.webp.se/).
