This Router App adds nodes to the Node-RED Router App and works only after the Node-RED Router App is installed.
Adding this router app to the router will add the gzip node to the function node palette. If the input is a compressed buffer, it tries to decompress to a UTF-8 string. If the input is a normal string, it creates a compressed buffer. See more information in the official documentation: https://flows.nodered.org/node/node-red-contrib-gzip
