Based on previous answers to similar questions such as this one, downloading, or in general, reading files from the assets directory should be a straightforward call to HttpClient
's get
method. For example if I have a DownloadService
, I could simply define it as:
export class DownloadService {
constructor(http: HttpClient){}
download(data) {
this.http.get('/assets/path/to/file.ext').subscribe(res => process(res));
}
}
However, when I test this using ng serve
, I get an error saying that /assets/path/to/file.ext
is not a valid URL. I tried ./assets/path/to/file.ext
, and assets/path/to/file.ext
but I got the same error. Do I need to configure something in the runtime to get this working properly, or has this changed since those answers were written? I'm using Angular 9.
This error occurs whenever you try to fetch something different than a JSON.
To fix it, please define the responseType
accordingly. For example
this.http.get('./assets/path/to/file.txt', {responseType: 'text'}).subscribe(res => process(res));
Also, please notice how I've changed the URL, it should be ./assets/foo.bar
Here's a working example https://stackblitz.com/edit/angular-9-starter-l1cn5j
Just check the console :)
By the way, these are the accepted types for responseType
:
responseType: 'arraybuffer'|'blob'|'json'|'text'
