Package description
@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.
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
});
}
This Babel plugin transforms ES6 class syntax to ES5. It includes handling of super calls and property accesses, similar to @babel/helper-replace-supers, but as part of a broader transformation of class syntax.
This plugin is part of the Babel preset for transforming ES2015 (ES6) classes to ES5. It handles super method calls and property accesses, ensuring compatibility with older JavaScript environments.
