Skip to main content

Server Application

You can write server-side applications with FigLang, FigCli has a command called server That will listen to the address and port you specified, each time a request arrives the CLI will run the script and pass the HTTP request content to the main function.

Server command​

Here is an example usage of the server command:

fig server ./test.fig --addr localhost:8080

Example server-side code​

Here is an example source code of using the server feature in FigCli, It's just like an ordinary Fig program but the main function will get one parameter, Which will contain the content of the HTTP request as char[] or a string.

test.fig:

import server;

export fn main (req: char[]): char[] {
    let headers = "Content-Type: text/html
Connection: Closed";

    let res = new_response("200", "OK", headers, "<h1>Hello World</h1>");

    return res;
}

The main function must return the HTTP response as a char[] or string. The return will be your app's response to the request.
