User Data

`buildfire.userData`#

userData is a framework provided in buildfire.js that allows the app user and app owner to save and retrieve simple and complex data. The framework facilitates CRUD operations common to all data operations as well as searching, sorting and paging complex data.

This service also takes care of all server side infrastructure to unburden the developer and app owner for developing the server side components and the costs of running a server. This service is provided out of the box at no additional charge.

The userData service also handles caching of data and other performance enhancements.

The use of the userData is completely optional. The developer may choose to communicate with his own custom api.

important

userData has read/write permissions on widget side. userData is data that is saved from the widget side and only accessable to user that initiated the request and only on current plugin. If you want to save data from widget side and have it available to other users, check out publicData or if you want data to be accessable by other plugins, check out appData

If you want to work with Geospatial data check GeoData Wiki

tip

To support high performance search and sort query check Indexed Fields

You can see an example of using User Data in https://github.com/BuildFire/simpleBuildFireJSExamples/tree/master/exampleWidgetUserDataPlugin

Methods#

`get()`
#

buildfire.userData.get(tag, callback)

Calls the userData to retrieve plugin data objects in JSON format.

note

If there are many objects with the same id, only one random record will be returned

buildfire.userData.get("main record", (err, result) => {
  if (err) return console.error("Error while retrieving your data", err);
  console.log("Main record", result.data);
});

  }
);

`onUpdate()`
#

buildfire.userData.onUpdate(callback, allowMultipleHandlers)

Allows you to pass a callback function that is called whenever the control updates data in the userData. Use this method in the widget to be notified that the control made a change so you can reflect that change directly in the widget. Returns a cleanup function to clear the listener.

let onUpdate = buildfire.userData.onUpdate((event) => {
  console.log("Data has been updated ", event);
});

// when you want to stop listening
// onUpdate.clear();

`callback(event)`#

Function you pass that gets called on each userData update

Name	Type	Description
`event`	object	Updated userData records

`allowMultipleHandlers`#

Name	Type	Required	Description	Default
`allowMultipleHandlers`	boolean	no	Tells the method to override all other handlers, or allow multiple handlers to exist at the same time.	`false`
