What is the best way to programmatically download a file in Angular 4 without explicitly specifying the file name?

Below is the code snippet:

importedSaveAs(blob, 'somefile.txt');

I'm currently facing an issue with hard-coding the file name in the above code. I would like to make it dynamic based on the response header. However, I'm unable to access the file name from the response header in this context.

Answer №1

Begin by making a call to the API to retrieve the necessary data

 this._http.get(requestURL)   // feel free to customize this step
    .toPromise()
    .then(this.extractData);

Upon receiving the data, proceed to pass it to the designated extract method

private extractData(res: Response) {
 let name = res.headers()

    importedSaveAs(blob, name);  

    }

At this point, the dynamic name is being transferred to your custom save function.
