Track video playback progress and display a video heatmap with React

In this article, we’ll go over one way you can set up viewer playback tracking and generate a video heatmap to display in a React app.

The image serves as a symbolic representation of the challenges and processes associated with load testing in the realm of web applications.  At the core of the depiction is a classic smiley face, which can be seen as the web application itself. It stands resilient and contented, an emblem of a well-optimized system that aims to please its users. The simple and cheerful expression on the face underscores the desired outcome of any web application: smooth performance and user satisfaction.  From the left, countless disjointed lines approach the ear, each representing different types and intensities of web traffic. These lines may illustrate varied user requests, diverse data inputs, or multiple sessions, echoing the unpredictable nature of user behavior and real-world web traffic. The chaotic convergence into the ear symbolizes the often overwhelming demands placed on a web application during peak times or during an aggressive load test.  Remarkably, from the right ear emanates a pristine sine wave. In contrast to the chaotic influx, this sine wave epitomizes the ideal output: smooth, consistent, and undisturbed performance. It embodies the aspiration of load testing – to transform unpredictable, high-volume requests into consistent and harmonious system performance.  Overall, the imagery compellingly conveys the essence of load testing for web applications: ensuring that amidst the cacophony of diverse user demands, the system delivers a uniform, reliable, and satisfactory user experience.
