A high-performance timer based profiler for React Native that helps you track big performance problems.

Overview

Slowlog is a high-performance timer tool designed for React Native that helps developers identify significant performance issues in their applications. Acting as a frontline defense mechanism, it is ideal for early-stage performance tracking before resorting to more complex tools like system trace and perftools. By integrating Slowlog into your React Native project, you can gain vital insights into your component performance while in developer mode.

This tool is easy to set up and use, allowing developers to apply it to components with minimal effort. With its user-friendly options, Slowlog empowers developers to tailor the performance tracking according to their specific needs, enhancing both the efficiency and efficacy of the performance management process in their applications.

Features

  • Easy Installation: Simply run $ npm i -S react-native-slowlog in your React Native project to get started quickly.

  • Developer Mode Only: Slowlog operates only in developer mode, ensuring that it does not impact performance in production.

  • Verbose Logging: The verbose option outputs all timing information to the console, while slow operations trigger warnings for easy identification.

  • Threshold Settings: Configure a threshold in milliseconds, allowing you to flag operations that exceed your desired performance metrics.

  • Custom Log Objects: Integrate with any console-like object that supports .log([msg]) and .warn([msg]) for personalized logging experiences.

  • Exclusion List: Customize your performance tracking by excluding specific components or operations using a dict format, keeping your focus on critical areas.

  • Community Contribution: Encourages collaboration with options to fork the project, implement your ideas, and contribute back to the community with tests and pull requests.

  • Open Source: Proudly licensed under copyright by Dotan Nahum, reflecting a commitment to transparency and community-driven development.
