I found this afternoon that there were different clients !
Before that, i assumed that it was just the DBMS with the writing HTTP API or Telegraf. So i started to code with node.js to make request with the http api. Then i found there was a node.js client, then i looked into it, and it seems that it’s not up to date.

Edit : Found that there is a node client for influx
So i really don’t know what to do now, and i feel fucked…
