    pass-context

    Higher-order function to create a function which receives its context as its first argument.

    What?

    Sometimes you want to use arrow functions with an API that was designed with context (this) in mind. This is a small library which will pass a function's execution context as that function's first argument. The arguments which are passed to the function are passed in addition to the context argument.

    Installation

    npm

    npm i -S pass-context
    

    The library function is the default export of the package.

    The library function is exported as passContext.

    Usage

    import pc from 'pass-context';
    const input = document.querySelector('.my-fancy-input');
    input.addEventListener('change', pc((ctx, event) => {
      // `ctx` is what is normally accessible with `this` as if a normal function were passed as the event listener.
      // `event` (and any additional arguments) are the normal arguments passed in-order after the context argument.
      // Since this is an arrow function, `this` is inherited.
    }));

    Detailed Usage Example

    import pc from 'pass-context';
    const fn = pc(({ foo }, bar) => foo + bar);
    console.log(fn.call({ foo: 'Hello, '}, 'World!')); // Logs "Hello, World!"
