JSON Response Transformation for node-http-proxy

node-http-proxy-json is a specialized library, currently at version 0.1.9, designed to intercept and transform JSON responses from a proxied server when used in conjunction with node-http-proxy. Its primary function is to allow developers to modify JSON payloads on the fly, making it suitable for scenarios like API mocking, data manipulation, or stripping sensitive information before the response reaches the client. The library handles responses compressed with `gzip` or `deflate`, as well as uncompressed data. Unlike general-purpose stream manipulation tools such as Harmon, which targets HTML/XML, node-http-proxy-json focuses exclusively on JSON. Given its last commit in 2016, the project appears to be abandoned, with no active development or maintenance, and no clear release cadence, making it potentially unsuitable for new projects requiring ongoing support or modern features.
