# @videojs/vhs-utils

vhs-utils serves two purposes:

1. It extracts objects and functions shared throughout @videojs/http-streaming code to save on package size. See [the original @videojs/http-streaming PR](https://github.com/videojs/http-streaming/pull/637) for details.
2. It exports generic functions from VHS that may be useful to plugin authors.

## Installation

```sh
npm install --save @videojs/vhs-utils
```

## Usage

All utility functions are published under dist and can be required/imported like so:

> es import using es dist
```js
import resolveUrl from '@videojs/vhs-utils/es/resolve-url';
```

> cjs import using cjs dist
```js
const resolveUrl = require('@videojs/vhs-utils/cjs/resolve-url');
```

> depricated cjs dist
```js
const resolveUrl = require('@videojs/vhs-utils/dist/resolve-url');
```

Objects and functions shared throughtout @videojs/http-streaming code.

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.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
