process.mainModule
稳定性: 0 - 弃用: 改为使用
require.main
。process.mainModule
属性提供了另一种检索 require.main
的方法。
不同之处在于,如果主模块在运行时发生更改,则 require.main
可能仍会引用更改发生前所需模块中的原始主模块。
通常,可以安全地假设两者指的是同一个模块。
与 require.main
一样,如果没有入口脚本,则 process.mainModule
将是 undefined
。
Stability: 0 - Deprecated: Use
require.main
instead.The process.mainModule
property provides an alternative way of retrieving
require.main
. The difference is that if the main module changes at
runtime, require.main
may still refer to the original main module in
modules that were required before the change occurred. Generally, it's
safe to assume that the two refer to the same module.
As with require.main
, process.mainModule
will be undefined
if there
is no entry script.
