Functions

• Router System
• Get Args & Form Data
• Response System (redirect,abort)
• Memory System (useful cache)
• Session (realized in memory sys)
• Event (trigger and timer)
• Hot-Loading (automatic restart after editing the file)

Try it

You just need import the file from github (or gitee)

import { Denly } from "https://deno.land/x/denly@V0.24/mod.ts";

let app = new Denly({
  hostname: "127.0.0.1",
  port: 808,
  options: {
    debug: true,
  },
});

app.route.get("/", () => {
  return "Hello Denly!";
});

app.run();

It's easy to use, you don't need to download other file, just import the package from online.

Hot-loading [unstable]

if you want the server automatic restart after the file edited, then you can use hot-loading.

deno run --allow-run https://deno.land/x/denly@V0.24/debug.ts ./mod.ts

URL parameters

You can define a URL parameter based on a regular expression.

app.route.regex("letter", /^[a-zA-Z]+$/g);
app.route.get("/user/:letter",(name: string) => {
    return `Hello ${name}`;
});

The framework is equipped with the following regular expressions by default:

• letter [ a-z A-Z ]
• number [ 0-9 ]
• email [ valid email ]
• phone [ phone number (for Chinese) ]
• date [ valid date ]

Error fallback

You can send different error status codes and customize how you handle them.

app.route.fallback(404, () => {
    return {
        header: new Headers(), // A headers object
        body: new TextEncoder().encode("<h1>404 Not Found</h1>"),
    };
});

// trigger it
app.route.get("/error/404",() => {
    return app.response.abort(404);
});

Output file

You can simply return a file.

app.route.get("/image",() => {
    // Auto-updates headers based on the suffix.
    return app.response.file("./background.jpg"); 
});

The file function have second parameter can set Content-Type.

Static route

app.route.resource("/static", "./public");

You can bind a static routes by passing the path to the local folder and the public alias to the resource function.

File upload

const file = app.request.file("file");
Deno.writeFileSync(_tempdir + "/runtime/upload/" + file.name, new Uint8Array(await file.arrayBuffer()));

You can use Request.file to upload file.
