deno install issue with github package uWebSockets.js

[birkskyum]

Version: deno 2.0.0-rc.2

https://github.com/unjs/crossws

Some projects use crossws, which use uWebSocksts, can't install, because uWebSockets.js isn't on npm, it's in here https://github.com/uNetworking/uWebSockets.js/

Affects anything that build on top of crossws, which is also everything build on vinxi:

Simple repro

Clone https://github.com/tanstack/tanstack.com
deno install (with deno 2.0 rc.2)

error: npm package 'uWebSockets.js' does not exist.

I tried extensively, and yep, that's not possible.

Also, porting uWS has already been dismissed : #3366 (comment)

You can install your dependencies with npm install - it supports NPM packages from GitHub.

@lucacasonato uWebSocket doesn't want to be on any package manager

@lucacasonato uWebSocket doesn't want to be on any package manager

npm has ability to install from github: URLs as pointed by Luca. Deno can't do that at the moment.

[dsherret]

This package defines an optional peer dependency on "uWebSocket.js": "*" and only a dev dependency on "uWebSocket.js": "github:uNetworking/uWebSockets.js#v20.33.0" (https://registry.npmjs.org/crossws). If I install with npm it ignores the failure for the optional peer I believe. I think Deno just has to ignore optional peer deps when the package doesn't exist.

Opened a PR in deno_npm for this denoland/deno_npm#69

This doesn't break anymore - awesome!

So how do i get uWebsocket insalled on deno 2.0.0-rc.8 - If at all possible
I do not have any deno experience, just want to try it because nodeJS runs into strange GC issues under high load for that project.

Running deno install provides this message

deno install
error: Error in hyper-express@6.17.2 parsing version requirement for dependency "uWebSockets.js": "github:uNetworking/uWebSockets.js#v20.48.0"

Caused by:
    Package specified a dependency outside of npm (github:uNetworking/uWebSockets.js#v20.48.0). Deno does not install these for security reasons. The npm package should be improved to have all its dependencies on npm.

    To work around this, you can use a package.json and install the dependencies via `npm install`.

But using npm install will install the build for nodeJs.
Resulting in the crash:

error: Uncaught (in promise) Error: This version of uWS.js supports only Node.js LTS versions 16, 18 and 20 on (glibc) Linux, macOS and Windows, on Tier 1 platforms (https://github.com/nodejs/node/blob/master/BUILDING.md#platform-list).

@BolverBlitz I have opened a new issue for that: #25956
