Solving your front-end performance problems can be hard, but identifying where you have performance problems in the first place can be even harder. In this workshop, Abhijeet Prasad, software engineer at Sentry.io, dives deep into UX research, browser performance APIs, and developer tools to help show you the reasons why your Vue applications may be slow. He'll help answer questions like, "What does it mean to have a fast website?" and "How do I know if my performance problem is really a problem?". By walking through different example apps, you'll be able to learn how to use and leverage core web vitals, navigation-timing APIs, and distributed tracing to better understand your performance problems.

This workshop has been presented at Vue.js London Live 2021, check out the latest edition of this JavaScript Conference.

FAQ

Sentry is a tool designed to monitor the health of application code. It assists software engineers by identifying errors and bugs in applications and has recently expanded its capabilities to include performance monitoring, helping users understand and optimize the performance of their applications across different platforms.

Sentry has expanded its services to include performance monitoring, which allows users to monitor and understand the performance of their applications in addition to identifying errors and bugs.

Sentry's performance monitoring is beneficial for a variety of applications, including web servers and web applications built for the browser. It is particularly focused on improving performance for applications built using Vue, Ionic, and Electron frameworks.

Web performance is considered an accessibility issue because slow, unusable, or unpredictable web applications create barriers for users, making them inaccessible and providing a poor user experience. Improving performance ensures that applications are accessible and usable by more people.

To identify performance issues in web applications, it's important to first understand the type of application and user operations relevant to the app. Performance monitoring tools like Sentry can help in measuring and interpreting performance data, focusing on aspects like bandwidth, latency, and resource usage.

Understanding the type of web application, whether it's a single-page application, a static site, or a hybrid, helps in recognizing the specific performance trade-offs and challenges associated with each type. This knowledge guides the optimization strategies that can be specifically tailored to improve performance effectively.

The user's perspective is crucial in web performance because it directly affects their experience and satisfaction. Performance improvements should focus on making sites load faster and become more responsive, thereby enhancing user satisfaction and potentially increasing retention and conversion rates.

Sentry uses a variety of tools to measure and improve web application performance, including browser APIs and integrations with frameworks like Vue. It provides data on key performance indicators such as load times, interaction readiness, and resource usage, enabling developers to pinpoint and resolve performance issues.

Everything Beyond State Management in Stores with Pinia
Top Content
State management is not limited to complex applications and transitioning to a store offers significant benefits. Pinia is a centralized state management solution compatible with Vue 2 and Vue 3, providing advanced devtools support and extensibility with plugins. The core API of Pinia is similar to Vuex, but with a less verbose version of stores and powerful plugins. Pinia allows for easy state inspection, error handling, and testing. It is recommended to create one file per store for better organization and Pinia offers a more efficient performance compared to V-rex.
