Node.js & Electron: Where to require several modules?

问题

Requiring 5-10 modules in a javascript file (eg. app.js) in a html file/render process window takes about 5 seconds to render that window, although the window is already visible. These required modules are needed for other windows as well, which seems slow. I understand that require is also synchronous.

Therefore, should I:

1. make this asynchronous, or
2. require these modules globally for current and new windows, or
3. call these via ipc from main.js if this is faster?, or
4. make this faster more practically some other way?
