Experimental Learning Record Store

NOTE: This is an experiment and not finished.

Overview

The goal is to implement a Learning Record Store for the TinCan/Experience API that supports cloud content delivery.

The initial focus is Articulate Storyline which uses the alternative syntax (everything is a post) for all transactions.

Implemented with Node.js.

Data is stored in-memory for ease and speed of testing. Database drivers will be added once the main transactions are implemented.

Testing

1. npm test
2. Articulate Storyline

How does it work?

1. Node.js with Express
2. Middleware to support CORS and OPTION.
3. Middleware to support methods verb override

• Handles routing when method=verb appears in the query string

4. Middleware to extract the parameters

• Extracts the body from POST/PUT
• Handles form encoded data when the content type is json
• Extracts the actual JSON payload from the content parameter

5. Middleware to extend the request object

• Adds functions to handle common TCAPI parameters

6. State Handler - GET/PUT/POST/DELETE for State Requests
7. Statement Handler - GET/PUT/POST/DELETE for Statement Requests

Supported Transactions

• GET /TCAPI/activities/state/
• PUT /TCAPI/activities/state/
• DELETE /TCAPI/activities/state/
• PUT /TCAPI/statements
