decorate

library1.0.0jsnpmunverified

decorate is a lightweight library (v1.0.0) that allows using decorators in JavaScript without needing transpilers like Babel or TypeScript. It provides a `decorate()` function that applies decorators to classes, methods, or properties. It is useful for environments where native decorator syntax is unsupported or to avoid build tooling. The package is stable but has low release cadence. It offers both ESM and CJS exports and works in Node.js and browsers. Differentiator: it enables decorator patterns without transpilation overhead.

default (decorate)

✓ import decorate from 'decorate'

✗ const decorate = require('decorate')

ESM default import. The package provides a default export. In CommonJS, use require('decorate').default.

Shows how to import and use decorate to apply class and method decorators without transpiler.

import decorate from 'decorate'; class MyClass { greet() { return 'Hello'; } } // Class decorator function function classDecorator(cls) { cls.prototype.version = '1.0'; } decorate(MyClass, classDecorator); console.log(new MyClass().version); // '1.0' // Method decorator (non-enumerable) function nonenumerable(target, key, descriptor) { descriptor.enumerable = false; return descriptor; } class MyClass2 { secret() { return 'hidden'; } } decorate(MyClass2, 'secret', nonenumerable); console.log(Object.keys(MyClass2.prototype)); // []

Debug

Known issues

gotchadecorate() mutates the class/prototype in place; it does not return a new class.

fix

The class is modified directly; treat it as mutation.

affects: >=0.0.0

gotchadecorate() applies decorators immediately when called, not at decoration time, so order matters.

fix

Apply decorators in the order they should execute.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: decorate is not a function

Using CommonJS require incorrectly; default export is under .default.

fix

Use import decorate from 'decorate' or const decorate = require('decorate').default;

Cannot use decorator on undefined

Decorator is not a function or is applied incorrectly.

fix

Ensure decorator argument is a function (class) or string (method name) followed by decorator function.
