Angular HttpClient streaming get request or have back-end trigger a request?

I've developed restful http services with Node to communicate with my angular front-end.

In the back-end I'm using the MSSQL npm package which is an extension of TEDIOUS npm package made by microsoft to communicate with MS SQL Server.

In that package I'm using the 'stream' function to listen for changes.

I'd want to trigger a get request on the Angular 6 front end from the backend when that happens, but after looking through the documentation I can't find anything that would facilitate this strategy.

Solution

  • Can't by definition -- must use websockets for two-way communication.

    Ended up implementing Socket.IO which has excellent documentation, tutorials and examples.
