Integrate a COVID-19 crisis communication chatbot on a website

This tutorial takes you through building a simple Node.js application that is connected to a COVID-19 chatbot using the Watson Assistant APIs. The steps are taken from this assistant-simple repository and adopted for 2020 Call for Code challenge. You can use this tutorial as a starting template for the COVID-19 challenge.
Learning objectives
In this tutorial, you will:
Learn how to create a simple Node.js application.
Connect the application to a chatbot using the IBM Watson Assistant APIs.
Test and run the application locally.
Deploy the application on IBM Cloud as a Cloud Foundry application.
Here is a demo of the final application:

Prerequisites
Sign up for an IBM Cloud account.
Download the IBM Cloud CLI. You will use it to push your Node.js application to the cloud.
Create a COVID-19 chatbot and connect it to data sources You need to get the credentials from that chatbot to use in your Node.js application:
Log in to your IBM Cloud account.

Create a mobile app to facilitate community collaboration

There is a growing interest in enabling communities to cooperate among themselves to solve problems in times of crisis, whether it be to advertise where supplies are held, offer assistance for collections, or other local services like volunteer deliveries.
For example, with the 2020 SARS-COV-2 (COVID-19 or “Novel Coronavirus”) crisis, federal and local governments may be rolling out broad programs, but cooperation at the local level is usually the most effective way of getting help to where it is most needed as quickly as possible. Traditional social media is one way of communicating within a community, but this is often not sufficiently structured to enable rapid discovery of help needed.
In the current crisis, we have already seen shortages of local food, medical equipment, and other supplies. In addition, the recommended (or required) self-isolation and social distancing measures can compound the problem by preventing people from easily getting to locations with the

Create a quiz app to assess online learning

As learning and collaboration moves online in response to the COVID-19 crisis, developers will need to build microservices to enable distance learning. As part of that learning, instructors need to be able to assess their students’ understanding of course material.
This tutorial shows you how to build a simple quiz app to assess learner understanding. A major benefit of the app is its flexibility: this starter kit can easily be adapted into a short essay app, a grading app, or other educational tool.
Loopback is an open source tool for quickly building a data api for your applications. Whatever your specific application’s purpose, Loopback gets you quickly writing application logic instead of data-handling code.

You can find code and related files for this tutorial in the accompanying GitHub repo.
You can also try a quiz and explore the api before you get started on your own app.
Learning objectives
By completing this tutorial, you will

Build an end-to-end application with LoopBack, Cloudant, and React.js

In this tutorial, learn how to build an end-to-end React.js application that serves as a dashboard to display sales data that is stored in a Cloudant database. See how to use LoopBack 4 to expose REST APIs to connect to the Cloudant database so that the frontend dashboard can call the APIs.
Overview
The are two main parts of this tutorial:

Part 1: Create the APIs connected to Cloudant using LoopBack: See how to create a LoopBack application lb4-sales-analytics that connects to a Cloudant database.
Part 2: Create the React application that calls the REST APIs created in Part 1: Learn how to build a dashboard application, lb4-sales-react-app, using React.js.
Prerequisites
To complete the steps in this tutorial, you need to:
Install Node.js 8.9+ and LoopBack 4 CLI.
Review LoopBack’s set of command line interfaces that help you create the LoopBack artifacts more easily.
Get the code for part 1 and part 2 so you can follow the examples
