LTI Test App

This app is for testing LTI with Canvas. It expects Canvas to be running locally via Docker. See Canvas for Docker setup instructions

Quick Start

1. Install dependencies

npm install

2. Build the Docker image

npm run docker-build

3. Run the Docker image

npm run docker-run

4. Alternitively, you can just run it via Node with node index.js instead of Docker.

This will start the app listening on http://0.0.0.0:3000. The app is set up to log request and responses, so you can see what the contents of the LTI launch flow are.
