Question

是否可以使用prop-types来检查常规Object，Function参数和返回值？

Answer 1

I presume you are talking about using the prop-types package outside of a React application. If that is the case - the answer is yes, but there are limitations.

To achieve this you need to explicitly call the PropTypes.checkPropTypes function. This usage is described here .

To check an object's shape you can use the shapeOf() function. When it comes to functions however, there is no good way I am afraid to check it's parameters or return value. There are several closed issues on the prop-types GitHub repository indicating that this is better suited for a type checking system such as Flow or Typescript . If you have a very simple setup or you are just getting into the JS ecosystem, I would advise you go with Flow as it is easier to inject into an existing project and can be adopted incrementally.

I hope this helps and answers your question.
