Package description

What is @babel/helper-replace-supers?

@babel/helper-replace-supers is a Babel helper module that assists in handling super method calls and super property accesses in JavaScript classes. It is particularly useful when transforming ES6+ code to ES5, ensuring that the semantics of super calls are preserved correctly.

What are @babel/helper-replace-supers's main functionalities?

Super Method Call Replacement

This feature allows you to replace super method calls within a class method. The `replaceSuper` function is used to handle the transformation, ensuring that the correct object and super references are maintained.

const { replaceSuper } = require('@babel/helper-replace-supers');

function replaceSuperMethodCall(path, state) {
  replaceSuper(path, state, {
    getObjectRef() {
      return path.node.object;
    },
    getSuperRef() {
      return path.node.super;
    },
    file: state.file
  });
}

Super Property Access Replacement

This feature allows you to replace super property accesses within a class. Similar to method call replacement, the `replaceSuper` function ensures that property accesses are correctly transformed.

const { replaceSuper } = require('@babel/helper-replace-supers');

function replaceSuperPropertyAccess(path, state) {
  replaceSuper(path, state, {
    getObjectRef() {
      return path.node.object;
    },
    getSuperRef() {
      return path.node.super;
    },
    file: state.file
  });
}
