var KeepItRefreshed = require('keep-it-refreshed');

KeepItRefreshed.PersistToken.create({
  url: 'some url',

  headers = { ... },
  body: 'some data',
  storageType: KeepItRefreshed.STORAGE_TYPES.LOCAL_STORAGE,
  storageKey: 'key',
  resultHandleTypes: [
      KeepItRefreshed.RESULT_PROCESS_TYPES.SAVE,
      KeepItRefreshed.RESULT_PROCESS_TYPES.CALLBACK,
  ],
  timeout: 300000 // time in ms to send request in
  recurring: true, // try same request after previous one has finished
});

KeepItRefreshed.PersistToken.on(KeepItRefreshed.EVENTS.SUCCESS, function(res) { ... });

API

create(options)

Initializes PersistToken with passed options

Arguments

• options (Object): An object that holds parameters Parameters:

  • url (string): Url to send a request to.

  • method (string): HTTP method.

    Default: 'GET'.

  • headers (Object): HTTP headers.

  • body (string): Request body.

    PersistToken does not modify the given body in any way

  • timeout (number): Time in milliseconds, after which PersistToken will send an HTTP request.

  • storageType (STORAGE_TYPES): Type of storage request response will be saved in.

    Available types:

    • LOCAL_STORAGE
    • SESSION_STORAGE

  • storageKey (string): A key, under which request response will be saved in a specified by storageType storage.

  • resultHandleTypes (Array[RESULT_PROCESS_TYPES]): Parameter to specify how request result will be handled.

    Available types:

    • SAVE: save response to storage
    • CALLBACK: call an added callback with response

    Default: [SAVE].

  • recurring (bool): If set to true, then after a request finishes the same request will be sent again.

on(event, callback)

Adds a callback for event

Arguments

• event (EVENTS): Name of event.

  Available events:

  • SUCCESS: function (result) - Raised after a successful request (status in 200 range).
  • FAIL: function (error) - Raised after a failed request (status >= 400).

• callback (function): Callback function.

Callbacks, added via on() will NOT be re-added after page refresh. Unfortunately, if you want to use callbacks, you will have to add them during app initialization. Sorry :(

start()

Starts a request.

stop()

Stops sending requests. You can start sending requests with the same configuration again by calling start().
