    Core Web Vitals: Put your application into orbit with best practices

    It's never easy to improve the user experience of a Web application. Yet it's important to do so: an application with a poor user experience is an application that won't be used and can ultimately cost a company dearly.

    In 2020, Google announced the integration of three new metrics into its performance auditing tools. These are known as Core Web Vitals and are as follows:
    - LCP: Largest ContentFul Paint
    - CLS: Cumule layout shift
    - FID: First Input Delay

    At Google I/0 2023, Google announced the new INP metric (interactive to next paint), which will replace the FID metric in 2024.
    But why deprecate the FID metric? What is the FID metric, and how can it be optimized? What are the best practices to follow in order to score well on previous metrics?

    In this talk, I'll answer all these questions with recommendations and examples you can use daily as a developer.

    • Core Web vitals.
    • Interactive to Next paint.
    • Breaking up long tasks.
