bound-decorator

@bound decorator

Decorator for creating bound methods using Babel 7 (sometimes referred to as "autobinding").

Note: This decorator is not compatible with legacy mode for decorators, regardless of your Babel version.

Also note that the ECMAScript decorators proposal is in the process of being redesigned. This redesign first became public in early 2019 and is still ongoing. As of January 2020, @babel/plugin-proposal-decorators is still based on the original stage 2 proposal, so this library is still fully compatible with it.

For Babel 6 and for TypeScript (at least as of 2018), you might be interested in these alternatives:

• https://github.com/andreypopp/autobind-decorator

Installation

npm i -S bound-decorator

Or:

yarn add bound-decorator

Usage

Simply add @bound to the method you want to be bound:

import bound from 'bound-decorator'

@bound
handleClick() {}

Example

Using React:

class Counter extends React.Component {
    state = {
        count: 0
    }

    @bound
    handleClick() {
        this.setState({ count: this.state.count + 1 })
    }

    render() {
        return <div onClick={this.handleClick}>{this.state.count}</div>
    }
}
