🚀 Declarative-first programming

Create, manage and scale applications and tools easily without having to think about everything.

const { shift } = std;

function getRandomInt(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

let myValue = getRandomInt(1, 3);

shift(myValue)
  .option(1 || 2, () => console.log("Cool"))
  .option(3, () => console.log("Too much!"));

⚡ .NET based environment

Portable, fast and powerful applications with all the features offered by the .NET environment via functions or interop.

const system = xrequire("dotnet:System");
const consoleWriteLine = system.getType("Console").getMethod("WriteLine", 0);

consoleWriteLine.invoke(["Hello world from .NET!", null]);

//Output: Hello world from .NET!

🧤 Hands on development

Create a complete application in few lines with zero dependency.

⚡ Melon:

const app = http.app();

app.get("/", () => "Hello world");
app.run();

//App running in http://localhost:80

⛔ Node.js:

const http = require("http");

const server = http.createServer(async (req, res) => {
    if (req.url === "/" && req.method === "GET") {
        res.writeHead(200, { "Content-Type": "application/json" });
        res.end("Hello world");
    }
}

server.listen(80, () => {
    console.log(`server started on port: ${80}`);
});

⛔ Deno:

const listener = Deno.listen({ port: 80 });
console.log("http://localhost:80/");

for await (const conn of listener) {
  serve(conn);
}

async function serve(conn: Deno.Conn) {
  for await (const { respondWith } of Deno.serveHttp(conn)) {
    respondWith(new Response("Hello world"));
  }
}
