Setting Up the Basic Tutor Interface with Go and Fiber

Setting Up the Basic Tutor Interface

Welcome to the first lesson of our course on developing a personal tutor web application with DeepSeek and Fiber! In this lesson, we will focus on setting up a basic tutor interface using Fiber (a popular web framework for Go) and HTML . This is an essential step in creating a user-friendly web application that enhances the learning experience. A well-designed interface is crucial for engaging students and ensuring they can interact with the tutor seamlessly.

Basic Tutor Interface Mockup

To help you better visualize the interface we're building, here's a simple mockup of how the tutor web page will look after following the steps in this lesson: text +------------------------------------------------------+ | Welcome to Your Personal Tutor | | What would you like to learn today? | +------------------------------------------------------+ | | | [Conversation appears here as messages] | | | | [User] Hello, can you help me with math? | | [Assistant] Sure thing! Let's get started with ... | | | +------------------------------------------------------+ | [ Type your question... ] | | [Send] [New Session] | +------------------------------------------------------+ The header is at the top, welcoming the user. The messages area is in the center, where the conversation between the student and tutor appears. At the bottom, there is an input field for typing questions, a Send button, and a New Session button.

HTML Rendering with Fiber and Go Templates

Fiber is a fast, minimalist web framework for Go that makes it easy to build web applications. Fiber provides built-in support for serving HTML content using Go's standard html/template package or compatible template engines. This allows you to render dynamic HTML pages by combining static templates with data from your application. Go's template engine enables you to: Insert dynamic Go variables into HTML Use control structures like loops and conditionals Create reusable template components By combining Fiber with Go's template engine, you can efficiently generate dynamic HTML content for your web application, keeping your application logic and presentation layer cleanly separated.

AppendMessage Function

To effectively display the conversation in our tutor interface, we use the appendMessage function. This function creates a new message element, assigns it a CSS class based on the message's origin (user or assistant), appends it to the conversation container, and ensures the view scrolls to the latest message.

HTML

<script>
    function appendMessage(role, content) {
        // Create a new div element for the message
        const messageDiv = document.createElement('div');
        
        // Assign a class to the message based on its role (user or assistant)
        messageDiv.className = `message ${role}`;
        
        // Set the text content of the message
        messageDiv.textContent = content;
        
        // Append the message to the messages container
        messagesContainer.appendChild(messageDiv);
        
        // Scroll the messages container to the bottom to show the latest message
        messagesContainer.scrollTop = messagesContainer.scrollHeight;
    }
</script>

<script>
    function appendMessage(role, content) {
        // Create a new div element for the message
        const messageDiv = document.createElement('div');
        
        // Assign a class to the message based on its role (user or assistant)
        messageDiv.className = `message ${role}`;
        
        // Set the text content of the message
        messageDiv.textContent = content;
        
        // Append the message to the messages container
        messagesContainer.appendChild(messageDiv);
        
        // Scroll the messages container to the bottom to show the latest message
        messagesContainer.scrollTop = messagesContainer.scrollHeight;
    }
</script>

The appendMessage function is crucial for dynamically adding messages to the tutor interface. It creates a new <div> element for each message, assigns a class to differentiate between student and tutor messages, and appends it to the messagesContainer. This function also includes a line to automatically scroll the conversation view to the bottom, keeping the latest messages in view. Note that the scrolling behavior will only work as intended after we implement the necessary CSS components in a later lesson.
