json_build is a C library typically used in Utilities, JSON Processing, Nodejs applications. json_build has no bugs, it has no vulnerabilities and it has low support. However json_build has a Non-SPDX License. You can download it from GitHub.

This PostgreSQL extension provides functions to help in building JSON of arbitrary complexity. All the functions return JSON. They can be called nested and combined, to build up complex tree structured JSON. VARIADIC "any" means that the functions will accept any number of arguments of any type, and Postgres will accept the call, although the functions themselves do enforce certain rules. If called with no arguments an empty object or array is returned. If an argument is an array, it is converted to a JSON array, if it is a record, it is converted to a JSON object, if it is JSON it is passed through as is. Object keys must be not null and scalar - use of arrays, records or JSON values as keys is forbidden. build_json_object must get an even number of arguments - the odd numbered arguments (counting from 1) are the keys and the following even numbered arguments are the corresponding values. json_object_agg aggregates any two columns into a json object.
