> **v7 is a full rewrite**, with a new, TypeScript-first `Provider` class. Coming from an earlier version?
> See [Migrating from ltijs v5](https://cvmcosta.me/ltijs/#/guides/migrating-from-v5), or the

The Learning Tools Interoperability (LTI®) protocol is a standard for integrating rich learning
applications within educational environments ([spec](https://www.imsglobal.org/spec/lti/v1p3/)). ltijs
implements a full LTI® 1.3 tool provider, including launches, Deep Linking, Assignment and Grade Services,
Names and Role Provisioning, and Dynamic Registration, as a pluggable, TypeScript-first library. You get a
working learning tool without implementing any of the underlying security and validation yourself.
## Quick start
```bash
npm install ltijs
```
```ts
import { Provider } from 'ltijs'
const provider = new Provider({
database: { url: 'mongodb://localhost/ltijs' },
})
provider.onResourceLink(async (context, request, response) => {
response.html(`Hello, ${context.idToken.user.name ?? 'learner'}!`)
})
await provider.listen()
```

walkthrough, including registering a platform. Or see a full working example in
