Nebula (HTTP Server)

This is a http server program which can be used with another program that requires a (simple) server implementation.

Feel free to give any feedback.

How to use:-

Main.java file can be referred for example.

Step 1 (Optional): Create an object of ServerProperties class. All the properties are optional. The KeyStoreFileName and KeyStorePassword are required for HTTPS server.

ServerProperties serverProperties = new ServerProperties();
serverProperties.setPort(8080);
serverProperties.setHost("127.0.0.1");
serverProperties.setKeyStoreFileName("/path/to/file.jks");
serverProperties.setKeyStorePassword("password");
serverProperties.setServerTimeoutInMillis(10000);
serverProperties.setServerName("Test Server");
serverProperties.setRootDirectory("");
serverProperties.setLogFileName("log_file.txt");
serverProperties.setLogDateFormat("[HH:mm:ss]");

Step 2: To start the server, create an instance of the HttpServer or HttpsServer class and assign it to Server class. Optionally, the serverProperties can be passed.

Server httpServer = new HttpServer();
Server httpServer = new HttpServer(serverProperties);
Server httpsServer = new HttpsServer();
Server httpsServer = new HttpsServer(serverProperties);

Step 3: Add the controllers to the server.

// create response object with 404 not found error and default response body
httpServer.addController("GET", "/index.html", request -> new Response(404));

// create response object with 200 status code and "This is index page" as the response body
httpServer.addController("GET", "/index.html", request -> {
    // process the request
    return new Response().setBody("This is index page");
});

Step 4: Call the start() method to start the server.

httpServer.start();

Step 5: Call the stop() method to stop the server.

httpServer.stop();
