Fuite is a command-line interface (CLI) tool designed to identify memory leaks in JavaScript web applications. It operates by launching Chrome via Puppeteer and executing defined scenarios to detect persistent memory retention.

Who should use Fuite?

Fuite is intended for web developers and quality assurance engineers focused on building and maintaining performant client-rendered single-page applications (SPAs). It helps them diagnose and resolve memory leak issues.

How does Fuite identify memory leaks differently from other tools?

Fuite distinguishes itself by running scenarios a specific number of iterations (default 7) and then precisely identifying objects that have leaked that exact number of times. This iterative approach helps filter out transient memory usage from true leaks.

When is the best time to integrate Fuite into a workflow?

Fuite is best utilized during the development phase or integrated into continuous integration/continuous deployment (CI/CD) pipelines. It can automatically flag new or regressing memory leaks, particularly in applications with dynamic client-side routing.

What specific types of memory leaks can Fuite detect?

Fuite is capable of detecting various types of memory leaks, including unreleased JavaScript objects captured via Chrome heap snapshots, orphaned event listeners, detached DOM nodes, and growing collections such as Arrays, Maps, and Sets.

Fuite is a CLI tool I'd use to systematically find memory leaks in JavaScript web applications. It leverages Puppeteer to simulate user flows, running multiple iterations to pinpoint persistent object retention, event listeners, and DOM nodes.
