The process of accessing files from the filesystem using AngularJS

I have a JSON file that I want to use in my Angular application. I came across a discussion here suggesting the use of $http.get to load JSON from the filesystem. However, I am encountering an issue where I keep getting a "http://localhost:9000/jsonFile.json not found" error when trying to load the file in the console (via $injector.get). My app structure, generated using Yeoman, is as follows:

app
  --scripts
    --services
      --jsonLoader.js
    --app.js
  --index.html
  --jsonFile.json

The jsonLoader.js file contains:

angular.module('jsonLoader', [])
.service('loader', function($http){
  var schema = {};
  $http.get('jsonFile.json')
  .then(function(res){
    schema = res.data;
  });
  return schema;
});

Despite trying different path combinations to locate the JSON file, I continue to receive a 404 error when accessing the service. Any help on this issue would be greatly appreciated!

Your issue does not seem to be related to Angular, but rather to your Grunt setup. It appears that your Grunt is not properly watching JSON files, which is causing your Angular application to be unable to access the JSON file you are attempting to utilize.

In order to make JSON files accessible, you will need to include the following code snippet in your Grunt file (which is typically a part of Yeoman for Angular):

  livereload: {
    options: {
      livereload: '<%= connect.options.livereload %>'
    },
    files: [
      '<%= yeoman.app %>/{,*/}*.html',
      '<%= yeoman.app %>/{,*/}*.json', //added this line
      '.tmp/styles/{,*/}*.css',
      '<%= yeoman.app %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
    ]
