In this chapter, we explored a few new technologies by building a simple Messenger chatbot. First, we started by adding Angular 2 as our view layer and overviewed the basics of the platform, such as modules, components, data binding, and DI.
After that, we moved to building the chatbot by setting up all required webhook endpoints and tokens. We then created a Wit.ai application and trained the chatbot with questions and answers data.
After we implemented the chatbot in our Meteor app, we installed and briefly overviewed Cassandra database.
The last addition to the stack was GraphQL. We created a schema and explored how we can query data from different sources (Cassandra and MongoDB) with only one round-trip to the server.
What have you learned and what can be your next steps?
On the frontend, you can add Redux to Angular 2 and have Redux to manage the state of the application.
