(updated: 20170319) WIP
This is part 3 in a series to build a sample application called QAVideos using API Connect. QAVideos is a Question and Answer application that uses videos instead of text. Think of QAVideos as StackOverflow meets Youtube. QAVideos will use LoopBack, API Connect, Open API Initiative (OAI formerly Swagger.io), OpenWhisk, Object Storage.
- In part 1 â€˜QAVideos (Part 1), Adding User Management to Node.jsâ€™, I added User Management to a Node.js app using API Connect.
- In part 2 â€˜QAVideos (Part 2), Adding a Custom Model and ORM in Node.js‘, I added a custom data model, i.e. a Video model, and used ORM to persist the model to a PostgreSQL database.
- In part 3 ‘QAVideos (Part 3), Extend Model and Using Open API Initiative (OAI) in Node.js‘, I extend the built-in User model with a Member, add a Question and Answer based on the Video model, and add a Sticker, while using the Open API Specification to define and manage the application and APIs.
- In next parts, the idea is to add other possibly features: deploy the OAI definition file to Bluemix via API Connect, add Object Storage for Video support, create an Ionic/Apache Cordova based mobile client, add an automated build, deployment and test script, add a Content Delivery Network (CDN) to the backend, add event-driven OpenWhisk APIs, containerize the application, add chat, and possibly more.
- Node, npm, and API Connect must be installed,
- Check if the â€˜apicâ€™ tool is installed, by running â€˜apic -vâ€™ from the commandline. If not installed, follow the installation instructions, here.
- Get the source code from part 2 of this tutorial.
- Install the ‘npm’ dependencies,
- Configure the file ‘~/server/datasources.json’,
- Test if QAVideos (part 2) is running correctly by typing â€˜apic startâ€™ in the root directory, open a browser and go to â€˜http://0.0.0.0:4001â€™ in your browser.

Open API Initiative (OAI, based on Swagger)
The OAI is based on Swagger.io, an API Framework. The OAI is an open API definition standard. Frameworks like API Connect use the OAI definition file to generate the server, client, data model and documentation.
