# express-enum-param
Middleware for ensuring that a request parameter can only assume certain values

## Installation

```shell
$ npm install --save express-enum-param
```
Requires `body-parser`.

## Usage
```javascript
import enumParam from 'express-enum-param';

let allowedAnimals = ['crocodile', 'heron', 'turtle'];

router.get('/', 
	enumParam('animal', allowedAnimals),
	(req, res) => {
    res.status(200).send();
});
```

The above code will return a 400 HTTP status code and a message informing the client that this parameter can only have values from a certain list if `animal` is anything else than `crocodile`, `heron`, or `turtle`.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
