How can stored values be updated? about data-store

[doowb]

You can use the .load method to "re-load" the data from the file.

If the code your writing could potentially have multiple instances of data-store accessing the same file at the same time, then you should probably "wrap" .get and .set to call .load before those operations to ensure the data in memory is current.

const store = require('data-store')({ path: process.cwd() + '/foo.json' });
const get = (...args) => {
  store.load();
  return store.get(...args);
};

const set = (...args) => {
  store.load();
  return store.set(...args);
};

Or you can extend the Store class:

const { Store } = require('data-store');

class MyStore extends Store {
  get(...args) {
    this.load();
    return super.get(...args);
  }

  set(...args) {
    this.load();
    return super.set(...args);
  }

  del(...args) {
    this.load();
    return super.del(...args);
  }

  hasOwn(...args) {
    this.load();
    return super.hasOwn(...args);
  }

  clone(...args) {
    this.load();
    return super.clone(...args);
  }
}

Even doing that, there is still a possibility of race conditions since multiple instances are accessing the same file.
