support install deno

[mfulton26]

Describe the bug

Attempting to install Deno fails immediately:

❯ curl -sL https://deno.land/install.sh | sh
curl: socket hang up

Inspecting network traffic for the browser document via DevTools reveals that the first issue is a CORS issue:

Access to fetch at 'https://deno.land/install.sh' from origin 'https://something.w-credentialless-staticblitz.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I then tried pasting the contents of https://deno.land/install.sh into a file and running it directly:

❯ sh install.sh
install.sh: line 7: unsupported shell syntax

For reference (and as the install.sh script might change with time), here is line 7:

if ! command -v unzip >/dev/null && ! command -v 7z >/dev/null; then

The shell (/bin/jsh/) appears to have limited functionality but as Stackblitz supports Node.js it seems to me that supporting Deno should also be feasible.

Does this require some specific work on Stackblitz's side to support Deno? (I'm sure folks would like Bun too.)

Steps to reproduce

1. Open a repo.
2. Create a file named install.sh.
3. Copy the content from https://deno.land/install.sh and paste them into install.sh.
4. Run sh install.sh

Expected behavior

Deno is successfully installed.

Parity with Local

• I have run the project in my local machine and I could not reproduce the issue.

Additional context

An alternative to supporting Deno installation would be for it to be installed out-of-the-box like Node.js is. This might be simpler in some ways but I'd want a way to specify which Deno version to load.
