If you're still using Apache when the whole world is going to be prone to nginx, you might be able to do everything you can to keep speed. You might tweak the modules to be loaded, using keepalive, fiddling with the Content negotiation module (mod_negotiation: Select a document that best matches the client's requirements from several documents), The followsymlinks directive, which allows soft links to be used in this directory, and the ability to rewr

In Nodejs, modules can be divided into core modules and file modules. The core module is compiled into binary code, which can be referenced only with require notation, such as (Require (' net ')). File module refers to a JS file, a JSON file, or a. node file. The path to add the file after referencing the file module:/.../.../xxx.js represents the absolute path
