Neo4j Modus Starter Kit

A full stack app showing how to use the Neo4j knowledge graph with Modus and AI models.

To get started:

• Create a free Neo4j Sandbox instance

• Add your Neo4j credentials to .env

MODUS_NEO4J_NEO4J_URI=<YOUR_NEO4J_CONNECTION_URI_HERE>
MODUS_NEO4J_USERNAME=<YOUR_NEO4J_USER_HERE>
MODUS_NEO4J_PASSWORD=<YOUR_NEO4J_PASSWORD_HERE>

• Install the Modus CLI

npm i -g @hypermode/modus-cli

• Install the Hyp CLI and sign in to Hypermode

By default we can take advantage of shared model hosting on Hypermode

npm i -g @hypermode/hyp-cli

• Start your Modus app

modus dev

This will start your Modus app locally

• Open the API Explorer

Open http://localhost:8686/graphql in a web browser

First, run the saveEmbeddingsToNeo4j mutation to generate movie embeddings and save to Neo4j.

mutation {
  saveEmbeddingsToNeo4j
}

Then search for movies using the findSimilarMovies Query field

query($title: String!, $num: Int!) {
  findSimilarMovies(title: $title, num: $num) {
    movie {
      id
      title
      plot
      rating
    }
    score
  }
}
