Keeps track of various kinds of meta data about a class or a method, without manipulating the target.
Behind the scene, a WeakMap is used to store the information.
npm install @aedart/js-metaimport Meta from '@aedart/js-meta';
class MyClass {
// ... body not shown ..//
}
// Add arbitrary data about MyClass
Meta.addClass(MyClass, {
name: 'MyClass',
description: 'Yarr, swashbuckling strength!',
maxLifetime: 23
});
// Obtain arbitrary data about MyClass
let metaData = Meta.get(MyClass); // Returns "@aedart/js-meta/src/Meta/ClassData" object
console.log(metaData.data);
// Outputs:
// {
// name: 'MyClass',
// description: 'Yarr, swashbuckling strength!',
// maxLifetime: 23
// }Please review internal documentation (@aedart/js-meta/src/Meta.js) for additional API information.
