Deno is JavaScript for the serverless era.
HTTP server
Examples using the HTTP server from the built in Deno standard library.
https://deno.com/deploy/docs/examples
import { serve } from "https://deno.land/std@0.155.0/http/server.ts";
JSX
Preact
This can be extended to render from JSX by including Preact and preact-render-to-string.
https://deno.com/deploy/docs/examples#ssr-jsx-preact
Note that some examples use a .jsx or .tsx file extension, so Deno Deploy knows to interpret a given file as JSX/TSX.
Nano JSX
Another option is to use Nano JSX as shown in this example:
https://deno.com/deploy/docs/using-jsx
Nano SSR
Website in a single file
https://deno.com/blog/a-whole-website-in-a-single-js-file
https://deno.com/blog/a-whole-website-in-a-single-js-file-continued
This example uses nanossr, which is a tiny server-side renderer that uses Nano JSX with twind under the hood for styling.
ESM modules
A fast, global content delivery network for NPM packages with ES Module format.
Deno 1.30 now has built-in Node modules.
node: URLs are supported as an alternative means to load Node.js builtin modules. This URL scheme allows for builtin modules to be referenced by valid absolute URL strings.
import { readFileSync } from "node:fs";
Installation
Add to PATH by editing .bashrc and add the two lines as mentioned when the installation finishes.
vi .bashrc
Check the verion
deno -V
deno --version

Extension: Deno for Visual Studio Code
