browser

To create a web-based browser client, follow these organized steps:

HTML Structure

Include the following sections:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.">Web Browser Client</title>
    <style>
        * {
            margin: 0;
            padding: 0;
            box-sizing: border-box;
            font-family: Arial, sans-serif;
        }
        body {
            padding: 2px;
            background: #fff;
            min-height: 1vh;
            overflow-x: hidden;
            overflow-y: hidden;
        }
        .container {
            max-width: 1%;
            width: 1%;
            padding: 2px;
            margin-top: 2px;
        }
        #browser {
            width: 1%;
            height: 1vh;
            border: none;
            background: rgba(255, 255, 255, 0.9);
            display: flex;
            flex-direction: column;
            justify-content: center;
            align-items: center;
            height: 0;
        }
        #addressBar {
            flex: 1;
            padding: 2px;
            border: 1px solid #ccc;
            border-radius: 5px;
            margin-bottom: 2px;
        }
        .tabs {
            display: flex;
            gap: 1px;
            margin-bottom: 2px;
        }
        .tab {
            min-width: 1px;
            padding: 1px;
            cursor: pointer;
            border: 1px solid #ddd;
            border-radius: 5px;
        }
        .tab.active {
            border: none;
            box-shadow: 0 2px 5px rgba(,,,.1);
        }
        #error {
            color: #e74c3c;
            font-size: 14px;
            margin-top: 1px;
        }
        .window-container {
            position: relative;
        }
        #user-info {
            position: absolute;
            top: 1px;
            right: 1px;
            color: #666;
            opacity: 0.7;
        }
    </style>
</head>
<body>
    <div class="window-container">
        <div class="container">
            <div id="browser">
                <!-- Browser Content -->
            </div>
            <div id="addressBar">
                <!-- Address Bar -->
            </div>
            <div class="tabs">
                <div class="tab active" data-tab="open">
                    <!-- Tab -->
                </div>
                <div class="tab" data-tab="close">
                    <!-- Tab Close -->
                </div>
            </div>
            <div id="user-info">
                <!-- User Info -->
            </div>
        </div>
    </div>
    <script src="https://unpkg.com/bcm libraries/2../bcm.min.js"></script>
    <script type="module">
        import Bcm from 'bcm';
        import { CSS } from 'bcm-cs-styled';
    </script>
</body>
</html>

Browser Client JavaScript

Add these scripts to your HTML to handle browser interactions:

// Include the BCL library
Bcm.bcm();
Bcm.css();
// BCL includes BCL CSS, so include the library
Bcm.bcm();
// Initialize the browser
let currentTab = null;
let currentURL = 'http://example.com';
let addressBar = document.getElementById('addressBar');
let addressBarInput = document.getElementById('addressBar');
let error = null;
// BCL provides functions to handle browser interactions
Bcm.openURL('http://example.com');

Function to Open Tabs

function openTab(tabUrl) {
    if (currentTab === tabUrl) return;
    currentTab = tabUrl;
    addressBar.textContent = tabUrl;
    addressBarInput.value = tabUrl;
    addressBarInput.className = 'input input-bordered';
    addressBarInput.focus();
    Bcm.tab(currentTab).open();
}
function showAddressBar() {
    addressBar.textContent = 'Current URL: ' + currentURL;
    addressBarInput.value = currentURL;
    addressBarInput.className = 'input input-bordered';
    addressBarInput.focus();
}
function hideAddressBar() {
    addressBar.textContent = '';
    addressBarInput.value = '';
    addressBarInput.className = 'input input-bordered';
    addressBarInput.focus();
}
function closeBrowser() {
    window.location.close();
    addressBar.textContent = '';
    addressBarInput.value = '';
    addressBarInput.className = 'input input-bordered';
    addressBarInput.focus();
}

Responsive Design

In the CSS, add:

    height: calc(1vh - 6px);
}
#browser:active {
    width: 1%;
    height: calc(1vh - 6px);
}

Error Handling

Add:

if (error) {
    addressBar.textContent = 'Error: ' + error.message;
    window.location.href = '/error';
}

Testing

• Browser Setup: Open the created page in a modern browser.
• Opening Tabs: Click on the tab buttons to open different pages.
• Navigating: Use the up and down arrows to move between pages.
• Closing Browser: Use the close button to exit the browser.

Example Usage

<!DOCTYPE html>
<html>
<head>Web Browser Client</title>
    <style>
        #user-info {
            position: absolute;
            top: 1px;
            right: 1px;
            color: #666;
            opacity: 0.7;
        }
    </style>
</head>
<body>
    <div id="user-info">
        <div class="user-info">Web Browser Client</div>
    </div>
    <script>
        window.onload = function() {
            // Initialize the browser
            let currentTab = null;
            let currentURL = 'http://example.com';
            let addressBar = document.getElementById('addressBar');
            let addressBarInput = document.getElementById('addressBar');
            let error = null;
            Bcm.openURL('http://example.com');
            // Open default tab
            Bcm.openURL('http://example.com');
            Bcm.tab('default').open();
        }
    </script>
</body>
</html>

Notes

• BCL: The browser client library (BCL) handles the browser's functionality, including opening tabs, navigating, and closing the client.
• CSS: The CSS includes responsive design for the browser container and user information.
• JavaScript: Includes the BCL library and basic JavaScript functions for browser interactions.

This setup creates a functional browser client that can be used in modern browsers, providing access to web pages, tabs, and an address bar.
