How to set proxy to overall all requests coming from application?

In Node JS, we can `import https` and set `https.proxy = "proxyDetails` However, I couldn't find a way to do so in Deno. I even tried to run node js child_process app with proxy over Deno, still not possible.

In Deno, proxy configuration is read from environmental variables: , and . According to the documentation, if these environment variables are not found, Deno falls back to reading proxies from the registry in the case of Windows.

Here's how you can set these environment variables:

and : These variables hold the URL of the proxy server. The format is for and for .
: This variable should contain a comma-separated list of domain extensions proxy should not be used for.

Please note that these environment variables need to be set in the environment where the Deno process runs. How to set these variables depends on your operating system and shell.

For example, in a Unix-based system with a bash-like shell, you can set these variables as follows:

Then, you can run your Deno program in the same shell session, and it will pick up these proxy settings.

Remember, this is a process-level setting and will affect all fetch and module download requests made by the Deno process.

If you want to set the proxy for a specific fetch request, you can do so by creating a custom HTTP agent with the proxy settings and passing it in the options of the fetch request. However, this feature is not currently supported in Deno according to the documentation.

According to the documentation, Deno reads proxy configuration from environment variables: , , and . If these environment variables are not found, Deno falls back to reading proxies from the registry in the case of Windows.

So, if the library you are using makes HTTP or HTTPS requests under the hood, these requests should respect the proxy settings defined in these environment variables.

does setting proxy config as environment variable somehow not work for you? i think it should exactly make any third party library fetch calls to also use the proxy
