bind-decorator

Context method binding decorator.

!TypeScript
!Typings

@bind is just a little faster version of @autobind for decorating methods only, by binding them to the current context. It is written in TypeScript and follows the latest decorators proposal.

- It will throw exceptions if decorating anything other than function;
- Since the implementation follows the latest decorators proposal where compartion betweeen this and target can not be trusted, @bind will always return a configurable, get accessor propertyDescriptor which will memomize the result of descriptor.value.bind(this) by re-defining the property descriptor of the method beeing decorated (Credits goes to autobind-decorator for memoizing the result).

If you are looking for not just method decorator but rather full class bounding decorator check @autobind.

Install

Install with npm:

``bash
$ npm install bind-decorator
`

![NPM](https://nodei.co/npm/bind-decorator/)

Usage

In JavaScript

`javascript
import bind from 'bind-decorator';

class Test {
static what = 'static';

@bind
static test() {
console.log(this.what);
}

constructor(what) {
this.what = what;
}

@bind
test() {
console.warn(this.what);
}
}

const tester = new Test('bind');
const { test } = tester;
tester.test(); // warns 'bind'.
test(); // warns 'bind'.
Test.test(); // logs 'static'.
`

In TypeScript

`typescript
import bind from 'bind-decorator';

class Test {
public static what: string = 'static';

@bind
public static test(): void {
console.log(this.what);
}

public constructor(public what: string) {
this.what = what;
}

@bind
public test(): void {
console.warn(this.what);
}
}

const tester: Test = new Test('bind');
const { test } = tester;
tester.test(); // warns 'bind'.
test(); // warns 'bind'.
Test.test(); // logs 'static'.
