Neo4j provider

Nodal.Neo4j uses the official Neo4j driver. Create one provider for the application lifetime so its Bolt connection pool can be reused.

await using var provider = new Neo4jProvider(new Neo4jOptions
{
    Endpoint = new Uri("neo4j://localhost:7687"),
    Username = "neo4j",
    Password = "secret",
    Database = "neo4j",
    GraphDataScienceEnabled = true
});

Queries compile to parameterized Cypher. Repeated-hop traversals and simple paths use native Cypher patterns. Mutation plans and migration history are committed through write transactions.

GraphDataScienceEnabled is an explicit capability declaration, not a plugin installer. When enabled, analytics compile to parameterized GDS stream procedures over the named projection selected by OnProjection. Leave it disabled when GDS is not installed so unsupported operations fail before Bolt execution.

For edition- or version-specific deployments, populate AnalyticsAlgorithms from CALL gds.list() instead of advertising every compiler-supported algorithm. The current live database baseline is Neo4j 5.26 Community; analytics compilation targets its compatible GDS 2.13 API family, with live analytics certification still pending.

Never store production credentials in source control. Supply them through your host's secret configuration system.
