tiny

提供图片的转换处理以及文本的压缩，有HTTP与GRPC的调用方式，建议配合tiny-site使用。

png PNG的优化处理使用pngquant
jpeg JEPG的优化处理使用mozjpeg
avif AVIF的优化处理使用cavif
图片输出支持webp, jpeg, png, avif
数据压缩输出支持brotli, gzip, snappy, lz4, zstd

编译proto

需要先安装protoc-gen-gofast：

go get -d github.com/gogo/protobuf/protoc-gen-gofast

make protoc

启动

docker run -d --restart=always \
  -p 7001:7001 \
  -p 7002:7002 \
  --name=tiny \
  vicanso/tiny

其中7001提供HTTP服务，7002提供GRPC服务，默认http body限制为1MB，如果需要调整，可通过ENV来调整，如TINY_BODY_PARSER_LIMIT=10MB

示例

以brotli方式压缩文件（需要注意，只有HTTPS或者以IP形式打开，chrome才支持br）：

curl 'http://127.0.0.1:7001/texts/optim?output=br&quality=11&url=https://cdn.staticfile.org/jquery/3.4.1/jquery.min.js'

以POST的形式指定文本压缩：

curl -XPOST -H 'Content-Type:application/json' -d '{
	"data": "strings.........",
	"output": "gzip"
}' 'http://127.0.0.1:7001/texts/optim'

将png转换为webp:

curl 'http://127.0.0.1:7001/images/optim?output=webp&quality=80&url=https://www.baidu.com/img/bd_logo1.png'

以POST的形式指定图片转换：

curl -XPOST -H 'Content-Type:application/json' -d '{

客户端

tiny客户端主要用于图片预处理，可以将指定目录下的所有图片压缩优化，参数如下：

Usage of tiny:
  -filter string
    	filter regexp for image (default ".(png|jpg|jpeg)$")
  -jpeg int
    	the quality of jpeg, it should be >= 0 and <= 100 (default 80)
  -png int
    	the quality of png, it should be >= 0 and <= 100 (default 90)
  -server string
    	grpc server address (default "tiny.aslant.site:7002")
  -source string
    	search path (default ".")
  -target string
    	optim target path, new image will save to this path
  -webp int
    	the quality of webp, it should be >= 0 and <= 100

平时常用中，建议启动自己的tiny server，将-server参数指定为该服务，避免网络传输带来的压缩延迟。使用默认参数将/Downloads目录下的图片压缩优化并保存至/tmp/images中：

tiny -source=/Downloads -target=/tmp/images
