Fast, minimalist web framework for Deno ported from ExpressJS


Fast, minimalist web framework for Deno ported from ExpressJS.

Getting Started

import { opine } from "";

const app = opine();

app.use((req, res) => {
  res.send("Hello World");



This is a Deno module available to import direct from this repo and via the Deno Registry.

Before importing, download and install Deno.

You can then import Opine straight into your project:

import { opine } from "";

Opine is also available on, a package registry for Deno on the Blockchain.

import { opine } from "";


  • Robust routing
  • Focus on high performance
  • Large selection of HTTP helpers including support for downloading / sending files, etags, Content-Disposition, cookies, JSONP etc.
  • Support for static serving of assets
  • View system supporting template engines
  • Content negotiation
  • Compatible with SuperDeno for easy server testing
  • Supports HTTP proxy middleware with opine-http-proxy

And more to come as we achieve feature parity with ExpressJS.



The Express philosophy is to provide small, robust tooling for HTTP servers, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs.

Opine will aim to achieve these same great goals, focussing first on developing robust tooling and features before moving onto accelerating performance and becoming super lightweight.

As time passes, Opine’s goals may naturally diverge from ExpressJS and this will be reflected here.


To run the examples, you have two choices:

  1. Run the example using Deno directly from GitHub, for example:

    deno run --allow-net --allow-read
  2. Clone the Opine repo locally:

    git clone git:// --depth 1
    cd opine

    Then run the example you want:

    deno run --allow-net --allow-read ./examples/hello-world/index.ts

All the examples contain example commands in their READMEs to help get you started for either of the above methods.
