Use the Neo4j JavaScript driver's executeQuery API for standard query execution, retrieve values with record.get, and consume streams inside transaction callbacks to ensure safe result handling. For retry logic, use managed transactions like executeRead and executeWrite.

To handle Neo4j Integer serialization correctly, convert Integer and temporal types before passing them to JSON.stringify or APIs, as native JavaScript numbers lose precision with large Neo4j integers. Use proper TypeScript types like Node<Integer> to enforce safe conversions.

Yes, the Neo4j JavaScript driver supports both Node.js and browser environments. You must select the correct URI scheme for your target, such as Neo4j Aura versus local deployment, and verify connectivity on startup using a single shared driver instance.

Perform efficient batch writes in Neo4j by passing an array of parameters to a Cypher UNWIND statement via the JavaScript driver. Ensure proper parameter handling, especially for integers, and execute the batch within executeWrite or session.run for implicit transactions.

A Neo4j session throws SERVICE_UNAVAILABLE or similar Neo4jError codes when connections fail or constraints are violated. Ensure you use safe async/await patterns, maintain a single driver instance, and reliably close sessions to prevent connection pool exhaustion.

Use executeRead or executeWrite for managed transactions requiring automatic retries and error handling. Use session.run for implicit transaction scenarios like LOAD CSV, where you need direct control over the transaction lifecycle and manual result consumption.
