proxy-agent not working on Deno Deploy

I'm trying to use a proxy for the node-fetch requests in a deno app.

I chose proxy-agent npm package and its working great on my local. It reads HTTP_PROXY environment variable and uses that host as the proxy.

But when I deploy my app in Deno Deploy, proxy is not working. I set the environment variable correctly but proxy-agent is just ignoring that?

I appreciate any help.

Based on the documentation, Deno Deploy does not currently support all npm packages. While Deno Deploy does support importing built-in Node.js modules, it does not support all npm packages. The package you're trying to use is not a built-in Node.js module, so it might not be supported in Deno Deploy.

Deno Deploy does support proxies for module downloads and the Web standard

fetch

fetch

API. Proxy configuration is read from environmental variables: , and . However, this is different from using a proxy within your application logic, which seems to be what you're trying to do with .

If you're trying to create a proxy server, the documentation provides an example of how to create a basic HTTP proxy server using the

fetch

fetch

API:

In this example, all requests are proxied to .

If you're trying to use a proxy for outgoing requests from your application, you might need to use a different approach, as might not be supported in Deno Deploy. Unfortunately, the documentation does not provide a clear answer on how to do this.

But proxy-agent is working on my local, so deno supports it. But apparently Deno Deploy doesn't? Isn't it weird that Deno supports it but Deno Deploy service doesn't? Are we sure this is the problem here?

For me too, even createHttpClient doesnt work because its unstable api and i cant find any other way to make it work... i guess the only way is to self host the sever
