wolfram-server

JSON based Wolfram Language expression evaluation server

Usage notes

The server accepts HTTP POST requests, where the body data consists of Wolfram Language code. It takes this code, as a string, and evaluates it. Finally it converts the evaluated expression to ExpressionJSON and sends this JSON expression back to the client making the request.

Starting the Wolfram Language server

General usage:

wolframserver.wls [port]

If port is omitted a random (available) port is automatically selected.

Example, launch the server on port 5858:

wolframserver.wls 5858

Connecting to the server

Examples of language specific clients are in the clients directory.
