What are the two ways of node export module

There are two ways to export modules

Exports can export multiple members

Module.exports can only export a single member, and the latter will overwrite the previous

1 、 module.exports

We can export the module directly by assigning a value to module.exports

Module.exports can export individual members

All the functions of exports can be realized by module.exports.

2 、 exports

The exports variable is a reference to module.exports provided by node.

Exports exports by adding attributes, and only one object can be exported.

If you point the exports variable directly to a value, it does not affect module.exports, but this is tantamount to severing the connection between exports and module.exports.

Examples are as follows:

/ / define the method, the constant const myPI = 3.14const add = (a _ r _ b) = > a + b / / Export, any of the two methods can / / method 1: exports.myPI = myPIexports.add = add// method 2: module.exports.myPI = myPImodule.exports.add = add// method 2 (deformation) module.exports = {myPI, add} these are all the contents of this article, "what are the two ways of node export module?"
