Strategies for updating JSON file content as data evolves

I am facing an issue with loading a json file that populates charts. The file is generated from external data sources and stored in the asset directory. Is there a method to automatically load the updated json file?

I have attempted to include the code for reading the json file in the initialization, after it, or when requesting the data. However, it does not refresh with the new json file.

Here is how I import the data:

import accessioningAnalyticsDataNC from '../../assets/data/Accessioning-Analytics-NC-Data.json';

I have a function called getData which reads and processes the data.

getData(location: string) {
    // Function logic here
}

Unfortunately, despite trying different approaches, the new json file is not being read once it's placed in the assets directory.

Answer №1

For optimal efficiency, I suggest utilizing the Injectable service for retrieving and storing JSON data instead of importing it directly.

import accessioningAnalyticsDataNC from '../../assets/data/Accessioning-Analytics-NC-Data.json';

By subscribing to the injectable function, you can stay updated with the latest data changes.

Answer №2

One possible solution is to utilize the ngOnChanges life cycle hook provided by Angular. This allows you to monitor changes and update your JSON data accordingly from its source.
