Question

我正在尝试一个基本的ElectronJS应用，其中我正在尝试从本地文件系统读取.xls文件并尝试对其进行解析：

Started POST "/occasions" for 127.0.0.1 at 2018-10-06 14:59:05 -0700

Processing by OccasionsController#create as HTML

It should have 3 people associated with this occasion."], ["created_at", "2018-10-06 21:59:05.931738"], ["updated_at", "2018-10-06 21:59:05.931738"]]
  ↳ app/controllers/occasions_controller.rb:34
   (1.6ms)  commit transaction
  ↳ app/controllers/occasions_controller.rb:34

Redirected to http://localhost:3000/occasions

Completed 302 Found in 10ms (ActiveRecord: 2.9ms)

该文件大约有300,000行，并且代码能够解析和登记所有行中的数据。但是，直到解析文件之前，应用程序GUI均无响应。如何使此代码在后台运行而不会出现此问题？

如何在后台的ElectronJS应用中解析大型.xls文件？
