Introduction

The Learning Tools Interoperability (LTI®) protocol is a standard for integration of rich learning applications within educational environments. ^ref

This library implements a tool provider as an Express server, with preconfigured routes and methods that manage the LTI® 1.3 protocol for you. Making it fast and simple to create a working learning tool with access to every LTI® service, without having to worry about manually implementing any of the security and validation required to do so.

Installation

Installing the package

$ npm install ltijs

MongoDB

This package natively uses mongoDB by default to store and manage the server data, so you need to have it installed, see link bellow for further instructions.

• Installing mongoDB

Database Plugins

Ltijs can also be used with other databases through database plugins that use the same structure as the main database class.

• Firestore Plugin

• Sequelize Plugin(MySQL, PostgreSQL)

Quick start

Setting up Ltijs

const path = require('path')

// Require Provider 
const lti = require('ltijs').Provider

// Setup provider
lti.setup('LTIKEY', // Key used to sign cookies and tokens
  { // Database configuration
    url: 'mongodb://localhost/database',
    connection: { user: 'user', pass: 'password' }
  },
  { // Options
    appRoute: '/', loginRoute: '/login', // Optionally, specify some of the reserved routes
    cookies: {
      secure: false, // Set secure to true if the testing platform is in a different domain and https is being used
      sameSite: '' // Set sameSite to 'None' if the testing platform is in a different domain and https is being used
    },
    devMode: true // Set DevMode to false if running in a production environment with https
  }
)

// Set lti launch callback
lti.onConnect((token, req, res) => {
  console.log(token)
  return res.send('It\'s alive!')
})

const setup = async () => {
  // Deploy server and open connection to the database
  await lti.deploy({ port: 3000 }) // Specifying port. Defaults to 3000

  // Register platform
  await lti.registerPlatform({
    url: 'https://platform.url',
    name: 'Platform Name',
    clientId: 'TOOLCLIENTID',
    authenticationEndpoint: 'https://platform.url/auth',
    accesstokenEndpoint: 'https://platform.url/token',
    authConfig: { method: 'JWK_SET', key: 'https://platform.url/keyset' }
  })
}
