JarCastingwebp-server-java
This is a Server based on Java, which allows you to serve WebP images on the fly.
And you can easily integrate into your project.
e.g When you visit
https://a.com/1.jpg，it will serve asimage/webpwithout changing the URL.For Safari and Opera users, the original image will be used.
Modified from n0vad3v/webp_server
-
Add a simple feature that you can config more image directory
-
And you can easily integrate into your Java project.
Integrate into your project
You need newer version than 0.3
1.Import this package by gradle or maven
if you use gradle
add to build.gralde
implementation 'moe.keshane:webp-server-java:{version}'
if you use maven
add to pom.xml
<dependency>
<groupId>moe.keshane</groupId>
<artifactId>webp-server-java</artifactId>
<version>{version}</version>
</dependency>
2. Initializing webp-server-java
To initial a server you need to create a WebpServerConfig object.
Two params of WebpServerConfig are Map<String,String> imgMap,List<String> allowedTypes.
imaMap is a map of request uri and image file path like
Map<String,String> imgMap = new HashMap<>();
map.put("/i","/home/ubuntu/pic");
map.put("/img","/home/ubuntu/pic2");
map.put("/","/home/ubuntu/pic1");
allowedTypes is a list of allowed image extension name like
List<String> allowedTypes = Arrays.asList("jpg","png","jpeg","webp");
and initial the server
WebpServerConfig webpConfig = new WebpServerConfig(imgMap,allowedTypes);
WebpServer server = WebpServer.init(webpConfig);
3. Get webp file or origin file
Server would return a webp image file if is not safari or origin image file if is safari.
The param is HttpServletRequest object.
File file = server.request(request);
Run as server
Create a 'config.json' file
If you are serving images at https://example.com/pics/tsuki.jpg and your files are at /var/www/image/pics/tsuki.jpg, then imgMap shall be {"/pics":"/var/www/image/pics/tsuki.jpg"}.
1. Download or build the jar package
Download the webp-server from release page.
2. config file
Create a config.json
{
"host": "127.0.0.1",
"port": 3333,
"imgMap": {
"/i": "/home/ubuntu/pic",
"/img": "/home/ubuntu/pic2",
"/": "/home/pic1"
},
"allowedTypes": ["jpg","png","jpeg","webp"]
}
You must provide a config file to run this server
3. Run
Run this Jar package like
java -jar webp-server-java.jar /path/to/your/config.json
screen or tmux
Use screen or tmux to avoid being terminated. Let's take screen for example
screen -S webp
java -jar webp-server-java.jar /path/to/your/config.json
(Use Ctrl-A-D to detach the screen with webp-server running.)
4. Nginx proxy_pass
Let Nginx to proxy_pass http://localhost:3333/;, and your webp-server is on-the-fly
WordPress example
location ^~ /wp-content/uploads/ {
proxy_pass http://127.0.0.1:3333;
}
Build your own Jar package
Install jdk8 and clone the repo
then
./gradlew build
./gradlew bootJar
