@babel/plugin-syntax-class-properties
Advanced tools
Package description
The @babel/plugin-syntax-class-properties npm package allows Babel to parse class properties, enabling developers to use class properties syntax in JavaScript. This plugin is purely syntactical and does not apply any transformations. It is often used in conjunction with transformation plugins to compile class properties to a format compatible with older JavaScript engines.
Class Properties Syntax
Enables the use of static and instance class properties directly within class declarations. This syntax is part of the ECMAScript proposal and allows for clearer and more concise class definitions.
class MyClass {
static myStaticProp = 42;
myInstanceProp = 'hello';
}This package not only allows Babel to parse class properties but also transforms them so they can run in environments that do not support this feature natively. It is more comprehensive compared to @babel/plugin-syntax-class-properties, which only enables parsing.
While not exclusively focused on class properties, this Babel preset includes capabilities to transform class properties based on the target environment. It is a broader tool that configures Babel plugins and polyfills according to the target browsers or runtime environments.
