在Windows上：如何使用上下文菜单中的“使用...打开”命令正确打开文件？

Question

When I use the context menu command "Open with..." within Windows 7, the OS opens a new instance of my Electron application. I would prefer, that if the application is already running, the file to be opened will be opened within the already opened instance and not in a new one.

How can I achieve that?

Answer 1

使用app.makeSingleInstance()函数，文档中有一个示例。

Answer 2

I think this doesn't depend on windows (like open with settings) & it's a application specific setting (if exists). I did a little search and found this link, maybe useful ;) https://www.npmjs.com/package/electron-single-instance
