将Express与NodeJS一起使用时-视图缓存如何工作？

Question

Express API:

view cache: Enables view template compilation caching, enabled in production by default

I have 2 questions:

1. In app.js view cache isn't explicitly set in the development block, should it be?

2. How does this caching mechanism work; is it analagous to memcache?

Answer 1

As you can see it from the source , view cache is enabled by default only on production environment. If you don't need caching on development (or other environments) you can omit setting it explicitly.

How view caching works instead is pretty simple. If enabled, express stores compiled template in process memory and renders the cached version. This way no temporary cache files are generated and the template is retrieved quickly from memory.
