How to update data from file in nodejs?

Question

JavaScript

There is a file points.json
var data = require('/points.json');
the file stores data that can be updated. how can update var data inside nodejs? at least once every 24 hours.

Answer 1

The easiest way is to force the application to restart every 24 hours. But I would just read this json through the fs module , not through require.
If this option is not suitable, then you can also reset the require cache. But I see no reason not to use fs.
Also, it's better to know directly when a file has changed, rather than guessing. Therefore, fs.watch can be used to watch a file and respond exactly when it changes.
