AtomicJolt LTI Client

This is a collection of Javascript used by Atomic Jolt to assist in handling a LTI launch.

Installation

npm i @atomicjolt/lti-client

Usage

For an example of how to use this library see https://github.com/atomicjolt/atomic-lti-worker

The application code using this library must implement the LTI Launch in 3 phases, providing the server side code for each phase and returning and html response for each phase. Phases 1 and 3 will include a call to the client side javacript contained in this library. See the 1Edtech working group documentation for more information about the LTI standard: https://www.imsglobal.org/activity/learning-tools-interoperability

1. Open ID Connect initialization
During this phase respond to the OIDC initialization request, attempt to write a state cookie and return and html page with a call to initOIDCLaunch

import { initOIDCLaunch } from '@atomicjolt/lti-client';

2. Redirect
Server side validate the redirect and then return an HTML page capable of redirecting to the final LTI launch

3. Handle the LTI launch.
Validate the request including checking the nonce server side. Check for a valid state cookie and then return an HTML page with a script that calls LtiLaunch from this library.

import { ltiLaunch } from '@atomicjolt/lti-client';
