deno VS deno_install

Deno's website has installation instructions for various operating systems, and its complete source code is available in its GitHub repo. I run macOS, so I can install Deno with HomeBrew:

I've been watching Deno with high hopes but haven't used it in anger yet

Much of Node.js is written in C, yet it's still called Node.js.

Deno has some JavaScript/TypeScript in it. On GitHub https://github.com/denoland/deno is 22.8% JavaScript and 13.2% TypeScript, and https://github.com/denoland/deno_std is 68.2% JavaScript and 31.6% TypeScript.

So to me it's misleading about the name, but not about what Deno is written in.

It is built in Rust & using V8, see the readme: https://github.com/denoland/deno

Node (javascript) is fine and its successor, Deno (written in Rust by the author of Node) is very promising.

import { App, Router } from "https://deno.land/x/[email protected]/mod.ts"; const app = new App(); const router = new Router(); // Define your API routes router.get("/hello", (ctx) => { ctx.response.body = "Hello, World!"; }); app.use(router.routes()); app.use(router.allowedMethods()); // Start the server app.listen({ port: 8000 }); console.log("Server is running on http://localhost:8000");

Deno: Deno with one of it's frameworks (like Fresh

lspconfig.denols.setup({ root_dir = lspconfig.util.root_pattern("deno.json", "deno.jsonc"), init_options = { lint = true, unstable = true, suggest = { imports = { hosts = { ["https://deno.land"] = true, ["https://cdn.nest.land"] = true, ["https://crux.land"] = true, }, }, }, }, on_attach = on_attach, })

https://deno.land/install.sh is a redirect to https://deno.land/x/install.sh, which is treated as any /x/ (community) module. These modules are immutable clones of github tags (in this case, https://github.com/denoland/deno_install/). If someone would manage to breach the AWS S3 buckets that we use for module storage, it wouldn't be just a problem for installation of the deno CLI, but a problem for any module on the registry.

In any case, Deno ships a lot more things but this is enough to get us started. Any additional information can be found on the official repository url that I will be linking at the end of the article. As for a little start, since nodejs has been used as a very popular web server, I thought it might be interesting to start building a deno version of it. To start off, let's install deno. Depending on your OS you might want to refer to Install Docs

You can find a list of different installation methods on the official deno.land documentation and the deno_install repo.

You can install Deno in a few different ways. I chose to install it with brew install deno, but you can check their docs for other methods.

See deno_install and releases for other options.
