"Exploring the process of making a REST call from an Angular TypeScript client to

I'm currently developing a Sessions Server for a project at work.

My dilemma lies in the fact that I'm struggling to find resources on how to make JavaScript HTTP calls from a server running with http.createServer() and server.listen(8080, ...) to my Angular Server hosted through ng serve on localhost:4200.

What I'm looking for, or rather needing, is something along the lines of the following pseudocode:

In my Angular TypeScript file, I require something similar to:

private listdata = new Array<string>();

ngOnInit(){}

constructor(private http: HttpClient){
   this.http.listen(method: "POST", address: "http://localhost:4200/data", callback: => (data){
       this.listdata = data;}
   )
}

This way, my Angular Application (Server) can accept REST calls from another Server.

In my JavaScript file, I would like to do something as follows:

http.post("localhost:4200/data", data, httpOptions);

This means, ultimately, my javascript server operating on localhost:8080 sends data to my angular server on localhost:4200.

I've attempted to research various sources, including HttpInterceptors, but have been unable to find a straightforward solution that's beginner-friendly like myself.

Is there a simple method for my automatically generated and hosted Angular Server to define routes it listens to and process the data directly for frontend use?

Thank you in advance :)

Answer №1

  1. It may be helpful to review the documentation once more.
  2. In my view, I tend to utilize a similar approach when making REST calls.

2.1 For REST functions, it is recommended to write them in httpService.service.ts file.

2.2 When utilizing REST for OAuth login, implementing HttpInterceptor can help manage auth guards and easily handle token expiration checks.
3. Lastly, if you are inquiring about displaying components based on user roles, routing management can allow different views for various users.
