What is the process of parsing a Java property file in AngularJS?

Question

What is the process of parsing a Java property file in AngularJS?

Is it possible to access a properties file from an AngularJS application that is located outside of the web server?

For example, in Java we can access a property file deployed separately from the project. Is there a way to achieve this in AngularJS?

I attempted to do this but I am receiving an 'undefined' result.

filter.properties:

key1=value1 
key2=value2

sampleController.js

var app = angular.module('sampleApp', []);
    app.controller('sampleController', function($scope, $http) {
    $http.get('filter.properties').then(function (response) {
        console.log('Value for key1 is ', JSON.stringify(response.data.key1));
    });
});

Answer №1

AngularJS provides various methods for accessing properties files.

A properties file, like any other file, has a .properties extension and consists of key-value pairs separated by an equal sign (=) on each line.

To convert a properties file into a JavaScript object, you can iterate through each line in the file, split it using the equal sign as a delimiter, and store the key-value pairs in a JavaScript object for quick access.

Here is an example of implementing this in JavaScript:

function extractProperties(propertiesFileContents){
  var keyValuePairs = propertiesFileContents.split("\n");
  var properties = {};
  for (var i = 0; i < keyValuePairs.length; i++) {
     var keyValueArr = keyValuePairs[i].trim().split("=");
     var key = keyValueArr[0];
     var value = keyValueArr[1];
     properties[key] = value;
  }
  return properties;
}

After testing Samuel J Mathew's solution and finding it effective, I encountered additional complexities in the properties file I was working with. This file contained multiple empty lines, commented-out lines, and white spaces around the "=" sign. To address these issues, I made some modifications to the code. The updated version is designed to handle these situations and may prove helpful for those dealing with more intricate properties files:

function processProperties(data){
    const keyValuePairs = data.split("\n");
    properties = {}

    for (var i = 0; i < keyValuePairs.length; i++) {
      const keyValuePair = keyValuePairs[i].trim();
      if (!keyValuePair || keyValuePair[0] === '#') {
        continue;
      }
      const keyValueArr = keyValuePair.split("=");
      const key = keyValueArr[0].trim();
      const value = keyValueArr[1].trim();
      properties[key] = value
    }

    return properties;
  }
