How to use deno in production

Question

I tried Deno (https://deno.land/) in local pc and some of its examples and we have to run the server before executing the APIs in the local environment.

I need to host it in the server so that I can call that API when we request, but i don't know how to do it.

I have the experience in hosting PHP,.NET in production mode i haven't used Nodejs yet so i don't know that process.

Answer 1

You can use the cloud provider of your preference, AWS, DigitalOcean, Azure... and install deno and then you can use pm2 using interpreter flag to automatically restart if the server crashes and/or start the server on boot.

The easiest way is to create an ecosystem.config.js

module.exports = {
  apps: [
    {
      name: "app",
      script: "./deno.js",
      interpreter: "deno",
      interpreterArgs: "run --allow-net --allow-read",
    },
  ],
};

And use interpreterArgs to pass arguments that you need to pass to deno.

Now all you need to do is:

pm2 start

Now your server will be available on whatever port you setup your server. You can use Nginx as a reverse proxy if you want too.

You can also use any process manager of your preference

Answer 2

You can just use:

pm2 start index.ts --interpreter="deno" --interpreter-args="run --allow-net"
