Clients

This page describes how to communicate with BaseX from other programming languages.

You can use the following light-weight language bindings to connect to a running BaseX server instance, execute database commands and evaluate XQuery expressions.

Most clients provide two modes:

• Standard Mode: connecting to a server, sending commands
• Query Mode: defining queries, binding variables, iterative evaluation

Please see the Server Protocol for more information on the available commands. Currently, we offer bindings for the following programming languages:

BaseX 7.x, BaseX 8.x and later

• Java: The default implementation
• C++: contributed by Karim Salama (based on SDL2_net)
• C++: contributed by Jean-Marc Mercier (based on libboost)
• C++: contributed by Ben Engbers (based on CMake)
• C#, contributed by the BaseX Team and Martín Ferrari
• C, contributed by the BaseX Team
• Golang: contributed by Christian Baune
• Erlang: contributed by Zachary Dean
• node.js: contributed by Andy Bunce
• Perl, contributed by the BaseX Team
• PHP: updated by James Ball
• Python: contributed by Hiroaki Itoh
• Python, using BaseX REST services: contributed by Luca Lianas
• R: contributed by Ben Engbers
• Raku: contributed by Wayland
• Rust
• Ruby, contributed by the BaseX Team
• V, contributed by Erik Peterson

With Version 8.0, authentication has changed. Some language bindings have not been updated yet. The update is rather trivial, though (see here for more details); patches are welcome.

BaseX 7.x (outdated)

• ActionScript: contributed by Manfred Knobloch
• Haskell: contributed by Leo Wörteler
• Lisp: contributed by Andy Chambers
• node.js: contributed by Hans Hübner (deviating from client API)
• Qt: contributed by Hendrik Strobelt
• Rebol: contributed by Sabu Francis
• Scala: contributed by Manuel Bernhardt
• Scala (simple implementation)
• VB, contributed by the BaseX Team

Many of the implementations contain the following files:

• BaseXClient contains the code for creating a session, sending and executing commands and receiving results. An inner Query class facilitates the binding of external variables and iterative query evaluation.
• Example demonstrates how to send database commands.
• QueryExample shows you how to evaluate queries iteratively.
• QueryBindExample shows you how to bind a variable to your query and evaluates the query iteratively.
• CreateExample shows how new databases can be created by using streams.
• AddExample shows how documents can be added to a database by using streams.

Changelog

• Updated: The replace and store functions have been renamed to put and putBinary.

• Updated: cram-md5 replaced with digest authentication.
