# jayphelps/core-decorators

Library of stage-0 JavaScript decorators (aka ES2016/ES7 decorators but not accurate) inspired by languages that come with built-ins like @​override, @​deprecate, @​autobind, @​mixin and more. Popular with React/Angular, but is framework agnostic.

## What it is
A library of stage-0 JavaScript decorators such as @override, @deprecate, @autobind, and @mixin, inspired by built-in annotations in other languages. It is framework agnostic and popular with React and Angular users, but is now effectively unmaintained.

## Use cases
- automatically bind class methods to instances with @autobind
- mark methods as deprecated with runtime warnings
- enforce method overrides with @override
- mix behavior into classes with @mixin
- prevent class instantiation with @readonly-style guards

## When to choose
- you are maintaining a legacy codebase already using stage-0 decorators with Babel 5 or legacy transform plugins
- you need simple runtime decorator utilities in an older JS toolchain

## When to avoid
- starting a new project, since the decorators spec has changed and the library is unmaintained
- you use TypeScript or modern Babel with stage-2/3 decorators, which are incompatible
- you need guaranteed long-term support or security updates

## Facets
- artifact type: library
- maturity: abandoned
- function: developer-tools
- domain: developer-tools, web-development
- platform: cross-platform
- tags: decorators, javascript, es7, autobind, mixin, deprecate, react, angular, nodejs
