Angular 2 GET request returns a 404 error

I have been attempting to reproduce the ngPrime datatable demo from this Github repository. Currently, I am working with the most recent version of Angular (4) and using angular-cli in development mode. Placing a JSON file into my app folder where the service is located did not solve the issue for me. Despite trying different path configurations, I am still encountering a persistent 404 error.

import {Injectable} from '@angular/core';
import {Http, Response} from '@angular/http';
import {Car} from './car';

import 'rxjs/add/operator/toPromise';

@Injectable()
export class CarService {

constructor(private http: Http) {}

getCarsSmall() {
    return this.http.get('./cars-small.json')
                .toPromise()
                .then(res => <Car[]> res.json().data)
                .then(data => { return data; });
 }
}

The code snippet above originates from their website. In order to make it work, I had to import rxjs toPromise and modify the angular core package definition accordingly.

import {Injectable} from 'angular2/core';
import {Http, Response} from 'angular2/http';
import {Car} from '../domain/car';

@Injectable()
export class CarService {

constructor(private http: Http) {}

getCarsSmall() {
    return this.http.get('/showcase/resources/data/cars-small.json')
                .toPromise()
                .then(res => <Car[]> res.json().data)
                .then(data => { return data; });
 }
}

The resolution came when I used the full path as shown below:

return this.http.get('/src/app/cars-small.json')

Answer №1

After a bit of trial and error, I discovered that this tweak actually did the trick-

return this.http.get('/src/app/cars-small.json')

It's odd how I had to navigate up two levels when the file was right there at the same directory level. I attempted using app/cars-small.json first, but unfortunately, that didn't solve the issue either.

Answer №2

Consider including the directory within your webpack bundle as an asset folder. This way, you can easily make requests like http.get('api/config.json')...

  "apps": [
{
  "root": "src",
  "outDir": "dist",
  "assets": [
    "api",
    "assets",
    "favicon.ico"
  ],....
