Reading data.json with HttpClient on Stackblitz?

Question

I have a tiny demo and it attempts to read app/data.json using the Angular HttpClient.

const post$:Observable = 

        

Answer 1

i think there are some issues about reading local json in stackblitz it doesn't return plain json just the index.html instead. but another way is mocking a request from local json, you can try:

import data from './data.json'

ngOnInit(){
  this.getDatas().subscribe(data=>{
    console.log(data)
  })
}

getDatas():Observable<any>{
  return of(data).pipe(delay(1000));
}

Currently, you can't get the JSON directly over HTTP, but you can import it instead

data.json

it returns resource of index.html instead of the data you expected

online example

import { of } from 'rxjs';
import data from './data.json';

export class AppComponent  {
  constructor(http:HttpClient) {

  }

  ngOnInit(){
    const post$ = of(data);
    post$.subscribe(console.log);
  }
}

Stackblitz currently doesn't serve static files except the case when they are in assets folder.

So you have two options here:

1) Import json directly as module

import data from './data.json';

console.log(data) // => {title: "Simulating HTTP Requsts", content: "This is off the hook!!"}

For more details See other answers

2) Move that json in assets folder(Note: you have to reload stackblitz to make it working):

http.get('/assets/data.json')
