The Challenge: Stale Interactions at YCPHacks

Hey everyone! Let's talk about something that came up during the YCPHacks Hackathon: the need to drastically improve how users interact with the system, specifically concerning check-ins and role changes. During the event, it became clear that the current setup was a bit clunky. Every time a user checked in or when an admin adjusted user roles, the system required a full-page refresh. This wasn’t ideal; it interrupted the flow, created unnecessary delays, and generally hampered the smooth user experience we aimed for. The goal of this article is to dive deep into why this was happening, and explore the solutions to provide a seamless and immediate update when these types of changes occur. We'll explore how to make these actions feel instantaneous, and thus enhance the overall experience for both hackers and admins. This meant that after every check-in or role change, participants were forced to wait for the entire page to reload. This delay disrupted the smooth flow of the event, and it created a frustrating experience for the users, especially when they were trying to focus on their projects. Furthermore, from the perspective of an administrator, managing user roles became a cumbersome task, as each change required a full page refresh. This system was not scalable. Imagine the difficulties that it would create in a big event. It would create a bottleneck of delays. So, how can we make these interactions feel immediate and snappy, providing an experience more in line with the fast-paced, dynamic nature of a hackathon?

This need for immediate updates is pretty common in web applications, and there are well-established approaches to tackle it. The key is to move away from the traditional, refresh-dependent model and embrace techniques that update the interface in real-time, or very close to it. This improves usability and makes the application feel much more responsive. In our context, this means that when a user checks in, the change should be reflected immediately on their profile and in any relevant dashboards, without needing to reload the entire page. Similarly, when an admin changes a user’s role, those adjustments should be instantly applied, ensuring the user has the correct permissions and access right away. The main point is to make the system as efficient as possible. The current method did not provide this efficiency. The overall goal is to improve the user experience and the admin experience in the application.

Understanding the Root Cause: Why the Refresh?

So, why were we seeing these full-page refreshes in the first place? To understand this, we need to consider what’s happening behind the scenes. Usually, the problem stems from how the front-end (what the user sees) communicates with the back-end (where the data lives). Here are some of the main reasons for this: traditional server-side rendering, the application may be built using a server-side framework that generates the entire HTML on each request. When a check-in or role change occurs, the server needs to re-render the entire page with the updated information. This process forces the browser to reload everything. Another reason is lack of asynchronous communication, the front-end might be making synchronous requests to the back-end. This means that the front-end waits for the server to fully process the request and send back a new response before updating the page. As a result, users have to wait for the whole cycle to finish, which leads to the full-page refresh. Finally, inefficient state management, when the application doesn't efficiently manage the state of the user's data on the front-end, the application might need to reload the whole page to reflect any changes. Any changes made to the server-side data may not be immediately available to the front-end without the refresh. All of these technical causes contribute to delays, which impact the user’s experience.

When a user checks in or a role is updated, a server-side process updates the database and then sends the new data back to the client. This typically requires a full page refresh because the client has to fetch the entire HTML again. To avoid these full-page refreshes, we need to find ways for the client and server to exchange data without requiring a full page reload. This will ultimately result in a better user experience for both the end user and for the administrator. We also want to streamline the check-in process by reducing the number of steps that the user has to take. A smoother check-in process improves the user experience as well. The same is true for updating the roles. The faster that an admin can update the roles, the more efficient the admin’s job will become. It is important to remember that efficiency is the goal.

The Solution: Modern Web Techniques

To address this, we can leverage several modern web development techniques. The main idea is to implement asynchronous updates to avoid full-page refreshes. Instead of a complete reload, the user's browser updates only parts of the page that have changed. Here are some solutions to consider:

  • AJAX (Asynchronous JavaScript and XML) / Fetch API: These technologies let the front-end make requests to the back-end without reloading the entire page. For instance, when a user checks in, a JavaScript function can send an AJAX request to the server, update the database, and then update the specific elements of the page that display the user’s check-in status. This eliminates the need for a full reload. You can use the fetch API to fetch data from the server or to post data to the server. The fetch API provides a more modern and flexible way to make these types of requests. AJAX and Fetch are essential in creating single-page applications (SPAs) that offer a seamless user experience.
  • WebSockets: WebSockets allow for real-time, two-way communication between the client and server. The server can push updates to the client immediately after a change, without the client needing to request them. In the context of YCPHacks, the server could send a message to the client the instant a check-in or role change happens, automatically updating the user interface. This is perfect for real-time notifications and is the most advanced. When any user action occurs, the server immediately sends a message to the client, without the client needing to request the update.
  • Front-End Frameworks (React, Vue, Angular): Modern frameworks like React, Vue, or Angular make it easier to manage the user interface efficiently. They use a virtual DOM and automatically update only the parts of the page that have changed. This approach simplifies the process of handling dynamic updates. For example, if a user's role is updated, the framework will rerender only the parts of the page that display role-related information, instead of refreshing the entire page. These frameworks provide state management capabilities that streamline the process of updating the user interface.

By incorporating these methods, we can achieve immediate updates, making the user experience much smoother. For example, when a user checks in, the system updates the display immediately, showing the change in real-time. Similarly, when an admin changes a user's role, the changes are instantly reflected on the user's page and in any relevant dashboards, allowing for improved efficiency and real-time interaction. It will also make the platform feel much more responsive and dynamic, which will improve the user’s engagement.

Implementation Steps and Best Practices

Let’s outline some steps to implement these solutions, along with some best practices. Keep in mind that the specific steps might vary depending on the technologies used in the project, but the general principles remain the same. First, when using AJAX or Fetch API, you need to set up the front-end to handle the requests. When a user checks in, a JavaScript function must be triggered to send a request to the server. You must also set up the back-end to handle the requests. The server should process the check-in and return a success message or the updated user data. Then you will want to update the front-end to reflect the changes. Use JavaScript to update the relevant parts of the page with the data received from the server. If using WebSockets, you need to establish a WebSocket connection between the client and the server. Then, configure the server to push updates to the client whenever a change occurs. Finally, you can use front-end frameworks to manage the DOM and the data flow. These frameworks simplify the process of updating the user interface efficiently.

Best Practices:

  • Error Handling: Implement robust error handling to manage failed requests and display appropriate messages to the user. This improves the overall robustness of the application. Handle any potential issues to ensure that users are informed about any problems that they may experience. Provide a positive experience even when errors occur.
  • Loading Indicators: Show loading indicators during requests to give users feedback that the system is working. This prevents confusion and improves the perception of the system’s responsiveness. These indicators help the user understand that the system is working on their request and helps the user to be patient. Without this, the system may seem slow.
  • Security: Secure all API endpoints to protect against malicious attacks. Always validate user inputs to protect the system. Make sure that you implement proper security measures for your server endpoints. This is very important when taking any input from the users.
  • Performance: Optimize the requests to be as efficient as possible. Minimize the amount of data transferred and cache data when appropriate. Use server-side caching whenever you can, which will help improve performance. Optimizing the performance will significantly improve the user’s experience.
