Hi have a 2k JSON and would like to send it compressed data over BLE uart.

On Espruino we have require("heatshrink").compress(data).

Does any one know a compatible way for nodejs to compress data that can be uncompressed in Espruino?

Does https://github.com/gfwilliams/heatshrink-js help for that?

Alternatively, maybe https://github.com/systemmonkey42/node-heatshrink

As @john says - I think the heatshrink-js build is what you want. It should be compatible with Node.js and it's the exact same algorithm and settings used for Espruino
