Why are there some modules in Node.js that can't be found on npmjs?

Why can"t some modules be found on npmjs on Node.js ? For example, the amqp module. Is it because npmjs did not deploy the information for this module? It doesn"t feel like it, either. Solve it?

may be some modules used internally, or other registry


knows what the problem is: it's because the search function of npmjs is not in place.
solution:

  1. search with package name + npmjs baidu or google.

it is recommended that some common packages npmjs are easy to find and can be searched directly. If you can't find it inside npmjs , use the search engine to add development efficiency.
