Hi, after read several messages I still have some troubles, could you please help me? I have never used environment variables before. Now, in settings.js I've added "env: process.env" just below " functionGlobalContext: {" like this: functionGlobalContext: { env: process.env Moreover, following other post and documents I've modifided the module.exports = { section like this: module.exports = { process.env.HOSTNAME = require('os').hostname(); process.env.FOO = 'just another bar'; but in this way it doesn't work. In order to make it works I had to write it as following: module.exports = { test1: process.env.HOSTNAME = require('os').hostname(); test2: process.env.FOO = 'just another bar'; I don't know if it's correct but is the only way I was able to make it working. So, in this way I can use the environment variables set inside the settings.js file. But I have 2 more needs: I would have the environment variables writes in an external file rather than inside settings.js. How can I do this? I would even pass as variables users and passwords, for nodes that requires connection like mysql, mqtt, etc. Briefly, since I have the some project for several users, I would like to have jast one file where to make these changing and let it read and passed to the flow at load, when node-red starts. Thanks

Oh sorry, I overlooked that that was a private conversation. So, giving the answer without explaining. Here is like I did (first time ever, perhaps there is a better way). Create external file named env-external.js (testing in a windows environment), with the following content: module.exports = { hostname : process.env.HOSTNAME = require("os").hostname(), mqttLocal: process.env.MQTTLOCAL = "192.168.1.50", mqttPublic: process.env.MQTTPUBLIC = "broker.hivemq.com", Lat: process.env.LAT = "-25.442414", Lon: process.env.LON = "-49.236903" , friend: process.env.FRIEND = "vercingetorix" } 2- Added this line to the top of settings.js (outside modules.export session): var env_external = require("./env-external"); 3- Restarted the runtime 4- Tested using a change node to read an environmental variable to msg.payload [r-01] 5- Sounds strange for me but it worked well right first time (apparently) :laughing: [r-02]
