First of all to start, we need to install Deno and this task is very easy for any operating system. See more at DenoLand.

\n


\nAfter Installation you can use the command Line tools to navigate around with deno. Run deno help to get more information\\

\n
$ deno --help\n
\n

This entry point can be a JavaScript (.js) file or TypeScript (.ts) file. But the great news is the possibility to use a URL that points to an app entry point.

\n

Deno’s website provides us with some great examples, like these.

\n
$ deno run https://deno.land/std/examples/welcome.ts\nDownload https://deno.land/std/examples/welcome.ts\nCompile https://deno.land/std/examples/welcome.ts\nWelcome to Deno 🦕\n
\n

You can also run a program using a file

\n
import { welcome } from 'https://github.com/jaquiel/deno-features/raw/master/std/welcome.ts'\n\nwelcome()\n
\n

Now getting back to what we intended to do in the begining i.e to make a deno server. Now that you know te basics of handling deno the task becomes really simple.

\n
    \n
  1. First Make a File named server.js
    2. \n
  2. \n

    Now import serve and websockets from denoland

    \n
    import { serve } from \"https://deno.land/std/http/server.ts\";\n
    \n
    3. \n
  3. \n

    Now setup the server using the code

    \n
    import { serve } from \"https://deno.land/std/http/server.ts\";\nconst server = serve({ port: 8000 });\nconsole.log(\"http://localhost:8000/\");\nfor await (const req of server) {\nreq.respond({ body: \"Hello World\\n\" });\n}\n
    \n
    4. \n
  4. \n

    After that run the server file using the following command

    \n
    deno run --allow-net --allow-read server.js\n
    \n

    So why the long way to run a file in deno when compared to node. In Deno's documentation it is clearly defined that deno is a secure runtime for JavaScript and TypeScript. To access to security-sensitive areas or functions, you must use permissions on the command line. Thus we need to specify the --allow-net and --allow-read flags to run a deno program in your system.

    \n
    5. \n
\n

You can find the basic documentaion regarding this on Deno Http

\n

Now that you know the basics of deno we can now move to making a basic chat app using Deno but lets save that for the next time.
