Classes

Interface which defines the raw connection with the database

Inteface define a common way to acquire a connection

Represents an instant capturing the date, but not the time, nor the timezone. Created Date objects are frozen with Object.freeze() in constructor and thus immutable.

Represents an instant capturing the date, the time and the timezone identifier. Created {@ DateTime} objects are frozen with Object.freeze() in constructor and thus immutable.

A driver maintains one or more Sessions with a remote Neo4j instance. Through the Sessions you can send queries and retrieve results from the database.

A driver maintains one or more Sessions with a remote Neo4j instance. Through the Sessions you can send queries and retrieve results from the database.

Represents an ISO 8601 duration. Contains both date-based values (years, months, days) and time-based values (seconds, nanoseconds). Created Duration objects are frozen with Object.freeze() in constructor and thus immutable.

Constructs a 64 bit two's-complement integer, given its low and high 32 bit values as signed integers. See exported functions for more convenient ways of operating integers. Use int() function to create new integers, isInt() to check if given object is integer, inSafeRange() to check if it is safe to convert given value to native number, toNumber() and toString() to convert given integer to number or string respectively.

Utility to lazily initialize connections and return them back to the pool when unused.

Provides a interaction with a ConnectionHolder without change it state by releasing or initilizing

Verifies connectivity using the given connection provider.

Logger used by the driver to notify about various internal events. Single logger should be used per driver.

Internal holder of the transaction configuration. It performs input validation and value conversion for further serialization by the Bolt protocol layer. Users of the driver provide transaction configuration as regular objects {timeout: 10, metadata: {key: 'value'}}. Driver converts such objects to TxConfig immediately and uses converted values everywhere.

Represents an instant capturing the date and the time, but not the timezone. Created LocalDateTime objects are frozen with Object.freeze() in constructor and thus immutable.

Represents an instant capturing the time of day, but not the date, nor the timezone. Created LocalTime objects are frozen with Object.freeze() in constructor and thus immutable.

Class for all errors thrown/returned by the driver.

Class for Node Type.

Class for Cypher notifications

Class for Path Type.

Class for PathSegment Type.

Class for execution plan received by prepending Cypher with EXPLAIN.

Represents a single two or three-dimensional point in a particular coordinate reference system. Created Point objects are frozen with Object.freeze() in constructor and thus immutable.

Class for execution plan received by prepending Cypher with PROFILE.

Get statistical information for a Result.

Records make up the contents of the Result, and is how you access the output of a query. A simple query might yield a result stream with a single record, for instance:

Class for Relationship Type.

A stream of Record representing the result of a query. Can be consumed eagerly as Promise resolved with array of records and ResultSummary summary, or rejected with error that contains string code and string message. Alternatively can be consumed lazily using Result#subscribe function.

A ResultSummary instance contains structured metadata for a Result.

Class for exposing server info from a result.

A Session instance is used for handling the connection and sending queries through the connection. In a single session, multiple queries will be executed serially. In order to execute parallel queries, multiple sessions are required.

Stats Query statistics dictionary for a QueryStatistics

Represents an instant capturing the time of day, and the timezone offset in seconds, but not the date. Created Time objects are frozen with Object.freeze() in constructor and thus immutable.

Represents a transaction in the Neo4j database.

Class for UnboundRelationship Type.

Variables

Constant that represents read session access mode. Should be used like this: driver.session({ defaultAccessMode: neo4j.session.READ }).

Constant that represents write session access mode. Should be used like this: driver.session({ defaultAccessMode: neo4j.session.WRITE }).

Object containing string constants representing predefined Neo4jError codes.

Check if a variable can be safely converted to a number

Cast value to Integer type.

Connection holder that does not manage any connections.

Interfaces

Raw observer for the stream

The query result is the combination of the ResultSummary and the array Record[] produced by the query

Interface to observe updates on the Result which is being produced.
