All applications that are built using a database like Neo4j are using database drivers to execute statements to update or query the data.
Neo4j drivers are mostly built on the binary bolt protocol. Official drivers exist for Java, JavaScript, .Net, Python, and Go (more to come). Other languages (R, Elixir, Ruby etc) are covered by community drivers.
Please ask your questions in the appropriate sub-category and only use this #drivers-stacks one if none fits. If you run into a bug, rather than posting it here, please create a GitHub issue.
If need be, we can also create new ones.
