strongmind-lti_provider_client v2.0.27855

#Introduction The LTI Provider Client provides a client api that is used to communicate with the LTI Provider endpoint.

#Getting Started 1. Installation process npm install lti_provider_client 2. API references configureClient(onLaunchFunction) -> Invoked on lti consumer launch passing the lti parameters PostScore(score) -> Passes a score back to the lti consumer.

#Usage Example for Aurelia First we want to initialize the lti client.

import { inject } from 'aurelia-framework';
import {LtiProviderClientService} from 'lti-client'

@inject(LtiProviderClientService)
export class App {
  constructor(token, ltiClient) {
    this.ltiClient = ltiClient;
  }

  //We use the attached lifecycle to configure the lti client and to pass the function to call when the consumer launches the tool.
  <b>
  attached() {
    this.ltiClient.configureClient(launchParams => {
      let toast = launchParams;
    });
  }
  </b>
}

Then to post scores back...

import { inject } from 'aurelia-framework';
import {LtiProviderClientService} from 'lti-client'

@inject(LtiProviderClientService)
export class Player
{
    constructor(lti){
        this.lti = lti;
    }

    <b>
    postScore(score){
        //The PostScore function takes a double and will call the outcomes url on the Consumer.
        this.lti.PostScore(score);
  }
  </b>
}

import { inject } from 'aurelia-framework';

@inject(LtiProviderClientService)
export class Player
{
    constructor(lti){
        this.lti = lti;
    }

    <b>
    sendMessage(score){
        //The SendCustomMessage will send data through to the lti provider parent window
        this.lti.SendCustomMessage(<any json or string>);
