In daily operation, I believe many people have doubts about the difference between require and import in vue component. Xiaobian consulted various materials and sorted out simple and easy operation methods. I hope to help you answer the doubts about "what is the difference between require and import in vue component"! Next, please follow the small series to learn together!

The differences between require and import in vue components are as follows

1. Essentially different

import is a deconstruction process, import syntax is transcoded to require; and require is an assignment process, the result of which is an object, number, string, function, etc., and then assigns the result of require to a variable.

2. Different specifications followed

import is a syntax standard in es6 that needs to be converted to es5 syntax; require itself is the way AMD specifications are introduced.

3. Different ways of calling

import is called at compile time and must be called at the beginning of the file; require is called at run time and can be called anywhere in the code.

4. different performance

Import only needs to import the specified module at compile time, depending on the interface in import; require introduces the module at run time and assigns it to a variable, with slightly lower performance than import.

5. Basic syntax is different

The object exported by import is structurally assigned to the entire module, and the object must correspond to the value in the module one by one; while require defines module.export in the exported file, and the type of the exported object can be any type, just use the require() method to call the object in the imported file.

At this point, the study of "what is the difference between require and import in vue components" is over, hoping to solve everyone's doubts.
