A Magical Web Screenshot Project

Crystal Ball 🔮 is a library that takes an array or file of URLs and returns a report with screenshots (using [Puppeteer](https://developers.google.com/web/tools/puppeteer/)), application headers and src/href references.

*For information on downloading and installing Node.js, see [nodejs.org](https://nodejs.org).*

## Usage
### Crystal Ball Command Line Install

```
$ npm install crystalball -g 
```

#### Crystal Ball (cli)

The *first* parameter is URL(s) (encapsulated in quotes, separated by commas) or a filename and followed by individual options.

##### Options

* `prefix` : Prefix http and https to each URL  
* `port` : Add additional port 8080 for HTTP and 8443 for HTTPS  
* `file` : Use the first parameter as a filename (instead of URLs) to parse *(URLs separated by a new line)*

If the last argument is a number, it will specify the number of concurrent connections *(default = 10)*.

*Note: The `file` argument **must** be included to use a filename.*

### Examples:

**Array of URLS:**  
`crystalball 'http://example.com, http://example1.com'`

**Array of URLS with Options:**  
`crystalball 'http://example.com, http://example1.com' prefix ports 15`

**File (must include `file` argument):**  
`crystalball 'example.txt' file`

**File with Options:**  
`crystalball 'example.txt' file prefix ports 15`

*Note: The **first** argument should be encapsulated in quotes.*

### Module Install

```
$ npm install crystalball
```

#### Modules

Import: `import * as O from "crystalball";`  
Require: `const O = require("crystalball");`

## Options

Options are passed as an object with the following properties and values.

* `file : true ` : Use filename as argument  
* `filename: "example"` :  Report filename *(defaults to `cb`)*
* `prefix: true ` : Prefix http and https  
* `ports : boolean` : Add port 8080 for http and port 8443 for https  
* `connections : number` : Number of concurrent connections *(default = 10)*

##### Example:

```javascript
O.see("example.txt", { file: true, filename: "example", prefix: true });
    => Report output in ./crystalball/example_date.html
    => Data output in ./crystalball/data/
```

## Functions

The `see` function takes an array of URLS and options.

```javascript
O.see(["http://www.example.com", "http://www.example2.com"], options);
    => Report output in ./crystalball/cb_date.html
    => Data output in ./crystalball/data/
```

The `file` function takes a filename and options.

```javascript
O.file("example.txt", options);
    => Report output in ./crystalball/cb_date.html
    => Data output in ./crystalball/data/
```

## Reporting
