Question 1

How to connect Neo4j to a React app?

Accepted Answer

Use the browser version via CDN or ESM imports, but ensure WebSocket support and manage driver lifecycles carefully to avoid connection leaks in single-page applications.

Question 2

Neo4j JavaScript driver vs neogma or other ORMs?

Accepted Answer

This driver is low-level and official, providing direct Cypher execution and full Neo4j compatibility, while ORMs like neogma offer higher abstraction with model definitions but may lag in feature support.

Question 3

How to handle large integers in Neo4j with JavaScript?

Accepted Answer

Use neo4j.int() for values outside Number.MIN/MAX_SAFE_INTEGER, and check with neo4j.integer.inSafeRange() to avoid precision loss; disableLosslessIntegers can simplify but risks data integrity.

Question 4

Can I use Neo4j driver in serverless functions?

Accepted Answer

Yes, but optimize connection pooling and driver instantiation per invocation to prevent excessive connections, and close drivers promptly to handle ephemeral environments effectively.

Question 5

What's the difference between async and reactive sessions?

Accepted Answer

Async sessions use Promises for standard async/await patterns, while reactive sessions leverage RxJS for streaming and reactive programming, ideal for real-time data flows in applications.

Question 6

How to set up transaction retry in Neo4j driver?

Accepted Answer

Configure maxTransactionRetryTime in driver options, defaulting to 30 seconds, to automatically retry on transient errors, as shown in the README's transaction function examples.
