Build a Neo4j-backed Chatbot with TypeScript
Course Description
at In this hands-on course, you will use the knowledge obtained from the Neo4j & LLM Fundamentals course to create a Movie Recommendation Chatbot backed by a Neo4j database.
You will take a simple chat interface that repeats the user’s input and modify it to answer questions about movies via the Neo4j Recommendations Dataset using GPT-4, complete with conversation history.
The chatbot will be able to answer questions like:
-
How many movies has Tom Hanks acted in?
-
What is the most popular movie in the database?
-
Can you recommend a movie for fans of The Matrix and Casino?
At the end of the course, you will have a working chatbot built in React using Next.js.
Prerequisites
This course relies heavily on the information in the Neo4j & LLM Fundamentals course. We recommend completing this course first if you have not already done so.
We also assume a basic understanding of TypeScript and Next.js. It is not required, but you may also benefit from taking the Building Neo4j Applications with TypeScript course to understand how the Neo4j JavaScript Driver works.
The course uses Next.js to build a simple chat interface. We do not focus heavily on the Next.js functionality, so it may be worth reviewing the Next.js documentation to understand how it works.
