Setup

This works with electron, so let's get a basic electron app going.

Create a folder; we'll call this one demo. In that folder create these three files.
```
demo/
├── package.json
├── index.js
├── index.html
```

Let's populate these files with some basic code.

FILE: package.json

{
  "name": "demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "node_modules\\electron\\dist\\electron ."
  },
  "author": "",
  "license": "ISC"
}

FILE: index.js

const {
    app,
    BrowserWindow
} = require('electron');

let win;

app.on('ready', () => {

    win = new BrowserWindow({
        width: 800,
        height: 600
    });

    win.loadURL(`file:///${__dirname}/index.html`);

    win.on('closed', () => {
        win = null;
    });

});

FILE: index.html

<!DOCTYPE html>
<html>
  <head></head>
    <body>

	  test demo
    
    </body>
</html>

Time to test if it works. Open up your command prompt (windows) and type these commands hitting enter after each one. Make sure you have Node.js installed which can be found here.
```
cd "C:\location\of\your\folder\demo"
npm i electron-navigation
npm start
```
From here on out if you leave your command prompt window open to the demo directory, you can run your app by typing.
```
npm start
```

Usage

In your main ~.html file you need to create 3 containers where the controls, tabs, and views will be auto placed into. The demo uses index.html as it's main file. EXAMPLE: index.html
```
<body>


  <div id="nav-body-ctrls"></div>
  <div id="nav-body-tabs"></div>
  <div id="nav-body-views"></div>

</body>
```
NOTE:
- The IDs are important. Make sure they are spelled correctly.
- If you don't want your users to control the pages you can get rid of the controls container. The ID for that is nav-body-ctrls .
- The order or location of these divs doesn't matter, and they also don't have to be div elements. For example: <main id="nav-body-views"></main>.

Now we need to apply the module by adding a script tag to the ~.html file so that it can add the tabs and controls to the containers we just created above.

EXAMPLE: index.html

<!-- your code here -->
<div id="nav-body-ctrls"></div>
<div id="nav-body-tabs"></div>
<div id="nav-body-views"></div>

<script>
    const enav = new (require('electron-navigation'))();
</script>

</body>

Now that we have this, let's give it a quick run. If you've been following the setup guide, it would be like this.
```
npm start
```

This should be all you need to get the basic functionality working. If you are confused and want some more examples including how to use local html files in the tabs then check out the demos on github.

Themes

You can apply themes by downloading the ones on github and putting them in your `<head>` tag.

EXAMPLE: index.html

<head>
  <!-- your code here -->
    
  <link rel="stylesheet" href="relative/location/of/theme.css">
</head>

The themes folder also has a template theming file that you can use to style the tabs and controls exactly how you wish.

FILE: theme-template.css

/* back button, grouped in: .nav-icons */
#nav-ctrls-back {
    /* fill:#000; width:24px; height:24px; */
}


/* back button with no history, grouped in: .nav-icons.disabled */
#nav-ctrls-back.disabled {
    /* pointer-events:none; opacity:0.5; */
}

Options

You can control how and if some elements are displayed by passing an options object through the main electron-navigation object.

const enav = new (require('electron-navigation')( { HERE } );

{ showBackButton : `<boolean>` }

Shows/hides the back button in #nav-body-ctrls. Defaults to true.

{ showForwardButton : `<boolean>` }

Shows/hides the forward button in #nav-body-ctrls. Defaults to true.

{ showReloadButton : `<boolean>` }

Shows/hides the reload button in #nav-body-ctrls. Defaults to true.

{ showUrlBar : `<boolean>` }

Shows/hides the url input in #nav-body-ctrls. Defaults to true.

{ showAddTabButton : `<boolean>` }

Shows/hides the add button in #nav-body-tabs. Defaults to true.

{ closableTabs : `<boolean>` }

Shows/hides the close button on tabs in .nav-tabs-tab. Defaults to true.

{ verticalTabs : `<boolean>` }

Changes the direction tabs are stacked in #nav-body-tabs. Defaults to false.

{ defaultFavicons : `<boolean>` }

Uses the default favicons instead of the unified color coded ones in .nav-tabs-tab. Defaults to false.

{ newTabCallback : `<function>` }

Before a tab is created, an optional callback is invoked with (url, options). It can be set for the ElectronNavigation instance or passed inside newTab() as an option.
Optionally, the url and options can be altered and returned inside the callback result. The callback may define a postTabOpenCallback, which will receive the created webview.
If a falsy value is returned, the tab will not be created.

// Simple callbacks which does not alter the parameters
(url, options) => {
    return true;
}

// Prevent tab creation
(url, options) => {
    return false;
}

// Callback which redirects the opened tab
// Altered parameters imply that the tab should be shown
(url, options) => {
    url = "about:blank";
    return {url};
}

// Invoke callback after webview creation
(url, options) => {
    options.postTabOpenCallback = webview => {
        console.info("New webview created: ", webview);
    }
    return {options};
}

{ newTabParams : `<function|array>` }

Parameters to pass to newTab() when a new tab is opened by the new tab button. The parameters may be an array or a function that returns an array. Defauls to ['http://www.google.com/', { close: options.closableTabs, icon: NAV.TAB_ICON }].
{ changeTabCallback : <function> }
Function to invoke with visible webview after a new tab has become visible.
// all options and their default values if omitted.
let options = {
    showBackButton: true,
    showForwardButton: true,
    showReloadButton: true,
    showUrlBar: true,
    showAddTabButton: true,
    closableTabs: true,
    verticalTabs: false,
    defaultFavicons: false,
    newTabCallback: null
}

EXAMPLE : index.html 
```html
<script>    
    // the order doesn't matter    
    const enav = new (require('electron-navgation')) ({
        showAddTabButton: false,
        showUrlBar: true,
        showReloadButton: false
    });    
</script>

Methods

You can control the webviews and tabs using the object variable you created.

const HERE = new (require('electron-navigation'))();

.newTab ( `url` , `options` )

url <string> required argument - Specifies the location of the webview. Will perform a search if no domain specified.

  useragent: "Super secret browser"   
}});
{ newWindowFrameNameBlacklistExpression: <RegExp> } - Whenever a window is opened through window.open(), a new-window event is emitted automatically. This option allows to specify frame names that should not trigger the creation of a new tab.
{newWindowFrameNameBlacklistExpression: /internallyOpened|popup[0-9]/i}
{ icon : <string> } - Changes the favicon. Defaults to "clean".
{icon: "default"}      // uses the regular favicon.
{icon: "clean"}        // uses a constant globe icon that is colored based on the default favicon.
{icon: "/path/to/image.png"}   // uses an icon you provide. Full or relative paths and other extensions are allowed.
{ title : <string> } - Changes the title of the tab. Defaults to "default".
{title: "default"}         // uses the title specified by the <title> tag.
{title: "custom title"}    // uses whatever title you type.

    contextMenu: true, 
    webviewAttributes: {},
    icon: "clean",      
    title: "default",   
    close: true       
}
return <object> - The webview element object. Allows you to use the properties and methods as described here Element API.
// example on how to allow plugins
let google = enav.newTab('http://www.google.com/');
google.setAttribute('plugins', '');
