This is a Proof-of-Concept library that provides PubNub-compatible JavaScript SDK for IoT and embedded devices capable of running JavaScript.

Minimal required ECMAScript version supported is ES5, but the code emitted should work on older implementations with correct polyfills.

This library is highly modularized, so you need to import multiple packages to get it working.

Start by importing the core module, which provides the necessary structure for other modules to work.

const LightNub = require('@lightnub/core')

You need to provide additional modules to include specific features. Some modules are tagged as networking or codec, you need at least one of each for the SDK to work correctly.

To instantiate the SDK with modules, you need to pass them as arguments to the LightNub function that you imported from @lightnub/core.

const LightNub = require('@lighnub/core')
const Module1 = require('@lightnub/module-1')
const Module2 = require('@lightnub/module-2')

const pubnub = LightNub(
    Module1,
    Module2,
)

// Now you can use pubnub
pubnub.module1Function()
pubnub.module2Function()

This module provides basic json and url codecs for JavaScript environments that have JSON.parse, JSON.stringify, decodeURIComponent and encodeURIComponent available as globals.

const LightNub = require('@lightnub/core')
const DefaultCodecs = require('@lightnub/module-default-codecs') 

const pubnub = LightNub(
    DefaultCodecs
)

This module provides networking for IoT boards that run Espruino. You need to pass the HttpModule into the module function.

const http = require('http')
const LightNub = require('@lightnub/core')
const EspruinoNetworking = require('@lightnub/module-espruino-networking')

const pubnub = LightNub(
    EspruinoNetworking(http)
)

This module provides the basic publish functionality.

const LightNub = require('@lightnub/core')
const Networking = require('@lightnub/default-networking')
const Codecs = require('@lightnub/default-codecs')

const pubnub = LightNub(
    Networking,
    Codecs
)

const keyset = {
    subscribeKey: 'demo',
    publishKey: 'demo',
    uuid: 'myUuid',
}

pubnub.publish({ message: { content: 'My message' }, channel: 'test', keyset: myKeyset }).then((response) => {
    console.log(response)
})
