Specifying proxy for http-proxy-middleware

Question

I have a nodeJS project for a front-end that connects to multiple micro services.When we do final deployments we actually deploy the built JS and HTML in a WAR file along with the backend.

However, for development we use the http-proxy-middleware so we are able to do quick changes and edits on the front-end and see the results.

Today though, I would like to be able to see the connections leaving NODE-JS and going towards our microservices.

Specifically, I want to tunnel them through fiddler ( which is an http proxy usually running on port 8888 ).

Does anyone know to do this?

I tried setting e.g. the following but it doesn't affect the outgoing connection:

npm config set proxy http://localhost:8888

npm config set proxy http://localhost:8888 is used to configure NPM to download packages through a proxy.

You will need to connect to fiddler's HTTP proxy instead of your usual backend, with the relevant HTTP headers for proxying.

So a request would look something like

http.get ({
    host: '127.0.0.1',
    port: 8888,
    path: 'http://actual.backend/url'
}, function (response) {
    console.log (response);
});

Well, the answer to my problem is to use fiddler as a reverse proxy:

https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/UseFiddlerAsReverseProxy

I came across it by accident partly. I thought maybe I can't intercept all requests, but I could set my endpoint as being fiddler.

I did that, and saw a response in fiddler from the Fiddler Echo Service.

It basically displays a page similar to:

Fiddler Echo Service
