Massive memory consuming when require('opentype.js') is run

Massive memory consuming when require(‘opentype.js’) is run in html of electron app I’m trying to use this library, but when I add

const opentype = require('opentype.js');

to my code. and It runs. but when I try to open DevTools it consumes all of my memory 5.6GB and it crashes.

I’m on a Electron project. I tried the code in the Main process and the renderer process and within the html code. All the same problem happens.

• I don’t have problems using other packages by require()
• I uninstalled opentype.js by npm and reinstalled several times. to see if I destroyed it somehow.
• If I try calling opentype.js in plain html, it works fine.
• try calling in express app process, it works fine also.

• I think it maybe an electron issue. Anyone who successfully used it in electron?

Environment

Version used: 0.8.0 Font used: none Node version: v8.10.0 Operating System and version (desktop or mobile): Windows 8.1/10, and OSX

Solved it by detuoring opentype variable through main process and passing it with remote module in electron

//in electron main process
global.opentype = require('opentype.js');
let mainWindow = new BrowserWindow();
mainWindow.webContents.send('init-opentype', opentype);

//in renderer process
var opentype = remote.getGlobal('opentype');
console.log(opentype);
>>Object {…}, BoundingBox:(...), Font:(...), Glyph:(...), Path:(...), load:(...).....

but still not sure why it doesn’t work directly in the renderer process I’ll notify when it all clears up.

@Jolg42 thanks again for advice

I won’t have the time to investigate this issue unfortunately but you should add a link to you repository if it’s public as an example.

I guess the best way to know what’s happening will be to record the memory consumption and see where it’s being allocated.
