Strip flow type annotations from your output code.
The babel-plugin-transform-flow-strip-types package is a Babel plugin that removes Flow type annotations from your code. This allows you to write type-safe code using Flow, and then strip out the type annotations when you compile your code for production, ensuring that the type annotations do not affect runtime performance.
Strip Flow Type Annotations
This feature removes Flow type annotations from the code. In the input code, the function `add` has type annotations for its parameters and return type. After using the plugin, these type annotations are stripped out, leaving only the plain JavaScript code.
/* Input Code */
function add(a: number, b: number): number {
return a + b;
}
/* Output Code after using babel-plugin-transform-flow-strip-types */
function add(a, b) {
return a + b;
}
The babel-plugin-transform-typescript package is a Babel plugin that removes TypeScript type annotations from your code. Similar to babel-plugin-transform-flow-strip-types, it allows you to write type-safe code using TypeScript and then strip out the type annotations during the compilation process. This plugin is specifically designed for TypeScript, whereas babel-plugin-transform-flow-strip-types is designed for Flow.
The babel-plugin-flow-react-proptypes package is a Babel plugin that converts Flow type annotations into React PropTypes. This allows you to use Flow for type checking during development and still have PropTypes for runtime type checking in React applications. Unlike babel-plugin-transform-flow-strip-types, which removes Flow types, this plugin transforms them into PropTypes.
Strip all flow type annotations and declarations from your output code.
