botkit-promise-storage

Returns a promise-based storage interface for botkit.

Usage

var controller = require('botkit').slackbot();
var promiseStorage = require('botkit-promise-storage')(controller);

promiseStorage.teams.get('teamId')
  .then(function(team) {
    console.log(team);
  })
  .fail(function(err) {
    console.log(err);
  });

This doesn't overwrite the storage interface for botkit but instead provides a new one interface you can use. Botkit relies on its own callback-based storage interface internally, so do not overwrite the existing storage module.

Interface

The returned storage object has the same interface as controller.storage with the addition of a merge method. Each method returns a promise. The following methods are exported for each scope (teams, channels, users):

all

Retrieves all data for this scope.

get

Takes an ID and will return either the data stored with that ID or undefined.

merge

A convenience method not found in the botkit storage modules. Takes an object with an id property and will merge it with any existing data with that ID. If there is no existing data with the given ID, this will function as a save.

Generally, merge should be preferred over save.

save

Takes an object with an id property and saves it. This will overwrite whatever data is previously stored with this ID.

Notes

This uses the promises A+ compliant q library for promises.
