babel-plugin-class-autobind

Please note that this will add implicit magic to your code

This plugin will autobind all handlers for components listed in directive '@autobind' prefixes = on, _on, handle, _handle;

Example

In

'@autobind Component';

class Component {
  constructor() {
  }
  handleMe(){}
  onMe(){}
  noBind(){}
  // @autobind-ignore
  onIgnored(){}
}

Out

class Component {
  constructor() {
    this.handleMe = this.handleMe.bind(this);
    this.onMe = this.onMe.bind(this);
  }
  handleMe() {}
  onMe() {}
  noBind() {}
  onIgnored() {}
}

Installation

$ npm install babel-plugin-class-autobind

Options

if no components are listed in directive - all handlers in file classes will be bound to class instance. (equal to @autobind *)
