How to get or load json data from Postgresql database in my view page using AngularJS?

I have one query that, I have couple of json objects(contains id and description) in Postgresql database. My requirement is: I need to display each and every json data(id and description) from Postgresql database to my view page on hitting the URL automatically (like: if we hit http://localhost:9000 then that json data should come from database and should be displayed on my view page in table format on loading). Please let me know that how to implement it ? (Any examples or any code). Thanks in advance. In btw: I'm loading these json objects from localhost via jquery/ajax call to database/server.

//it is used to send json data to server

    $scope.loadJson = function() {
      var file, fr, input, receivedText;
      receivedText = function(e) {
        var lines, newArr;
        lines = e.target.result;
        alert('lines: ' + lines);//gives json data
        newArr = JSON.parse(lines);
        $.ajax({
          type: 'POST',
          contentType: 'application/json; charset=utf-8',
          dataType: 'json',
          url: '/sendJson',
          data: JSON.stringify(lines),
          success: function(data) {},
          error: function(XMLHttpRequest, textStatus, errorThrown) {

        });
      };
      if (typeof window.FileReader !== 'function') {
        alert('The file API isn\'t supported on this browser yet.');
        return;
      }
      input = document.getElementById('fileinput');
      if (!input) {
        alert('Um, couldn\'t find the fileinput element.');
      } else if (!input.files) {
        alert('This browser doesn\'t seem to support the `files` property of file inputs.');
      } else if (!input.files[0]) {
        alert('Please select file before clicking \'Load\'');
      } else {
        file = input.files[0];
        fr = new FileReader;
        fr.onload = receivedText;
        fr.readAsText(file);
      }
    };

html:

<table border="1"> 
                        <tr>
                            <td>
                                <label>Select File:</label>
                                <input type='file' id='fileinput' accept=".json" name="fileinput"> 
                            </td> 
                            <td>
                                <input type='button'  value='Load' ng-click="loadJson()">
                            </td>
                        </tr>
                    </table>
