# removable-middleware

A middleware wrapper allowing you to remove and replace the wrapped middleware while the server is running.

> WARNING: It is not recommended to remove or replace middleware in a production

app [#2418](https://github.com/expressjs/express/issues/2418). However, removing middleware during development can be useful e.g. for

code-splitting.

## Installation

    npm install --save removable-middleware

## Usage

> Example: Hot-reloading a server app bundled with Webpack:

```js

import express from 'express';

import removableMiddleware from 'removable-middleware';

import myAppMiddleware from './myAppMiddleware';

const app = express();

const middleware = removableMiddleware(myAppMiddleware);

app

	.use(middleware)

	.listen(3000)

;

if(module.hot) {

	module.hot.accept('./myAppMiddleware', () => {

		import('./myAppMiddleware').then(module => middleware.replace(module.default));

	});

}

```

## API

### `removableMiddleware(initialMiddleware)`

Creates a new middleware that wraps the another middleware.

### `.replace(nextMiddleware)`

Replaces the wrapped middleware with another middleware.

### `.remove()`

Removes the wrapped middleware.
