Config Service

The configService object provides functionalities to load configuration data from a JSON file and retrieve specific configuration values.

Methods:

loadConfigData(): Promise<any>: This method loads the configuration data from the "assets/app-settings.json" file and stores it in the appSettings variable. It returns a Promise that resolves to true when the data is successfully loaded, or false if there was an error while loading the data.
getConfigValue(key: string): string:This method retrieves the configuration value associated with the given key from the appSettings object.

Parameters:

key (string): The key for which the corresponding configuration value should be retrieved.

Returns

string: The configuration value associated with the provided key. If the key does not exist or an error occurs while retrieving the value, an empty string is returned.

Usage Example:

// Usage example 1: Loading configuration data
configService.loadConfigData()
  .then((success) => {
    if (success) {
      console.log("Configuration data loaded successfully.");
    } else {
      console.error("Failed to load configuration data.");
    }
  })
  .catch((error) => {
    console.error("Error while loading configuration data:", error);
  });
 
// Usage example 2: Retrieving configuration values
const apiKey = configService.getConfigValue("apiKey");
console.log("API Key:", apiKey);
 
const apiUrl = configService.getConfigValue("apiUrl");
console.log("API URL:", apiUrl);

In this example, the configService object is used to load configuration data from the "assets/app-settings.json" file and retrieve specific configuration values using getConfigValue method. Before using getConfigValue, ensure that you have loaded the configuration data by calling loadConfigData method and that the JSON file contains the necessary configuration settings.
