Hello,
I’m new to Resin, Electron, and javascript so I apologize if this is a dumb question. I’m currently building a smart mirror project on a Raspberry Pi 3 B+ using Resin and Electron. The issue I’m having is I want to display diagnostic information on the mirror (as of right now just CPU load and memory usage). The problem I’m having arrises when I try to read from the /proc directory to get the live stats.
To start out, my directory structure looks like this (on my local machine before I push to resin):
resin-electronjs
|
|----Dockerfile.template
|----LICENSE
|----README.md
/app
|
|---bower.json
|---main.js
|---package-lock.json
|---package.json
|---start.sh
/node_modules
/data
|--index.html
|--clock.css
|--main_window.css
/js
|--bundle.js
|--clock.js
|--core.js
|--diagnostics.js
|--py_stats.js
I discovered that I can print the stats to the console once if I use “var fs = require(‘fs’);” at the top of the main.js file and then call this in main.js:
fs.readFile('/proc/meminfo', 'utf8', function(err, data){
console.log("GETTING MEM INFO");
if(err){
console.log("MEM READ ERROR");
console.log(err);
cb(err);
return;
}
console.log("MEMORY_INFO: " + data);
cb(null, memInfo);
});
The issue is, I want to be able to get the cpu/memory data in the core.js file so I can update the UI during runtime. To do this I used browserify to package everything into bundle.js so I can use “var fs = require(‘browserify-fs’)” at the top of the core.js file. when I do fs.readFile the same way as above though, it prints an error to the console saying that there is no file “/proc/meminfo”.
I’m not sure if this has to do with where the application is running but I can’t seem to access the /proc folder from within any of my .js files other than main.js
Thanks in advance for any help!
