An improved debugging experience for Node.js using Chrome DevTools, with features like child process attachment and file editing.
ndb is a debugging tool for Node.js that enhances the debugging experience by integrating Chrome DevTools. It provides features like automatic child process attachment, pre-module breakpoints, and in-UI file editing to streamline debugging workflows. It solves the problem of cumbersome and limited debugging in Node.js by leveraging familiar DevTools functionality.
Node.js developers who need advanced debugging capabilities, such as those working with complex applications involving child processes or requiring efficient breakpoint management. It's also suitable for developers familiar with Chrome DevTools who want a consistent debugging experience across browser and server-side JavaScript.
Developers choose ndb because it offers exclusive Node.js-specific features not available in standard debuggers, combined with the powerful and familiar interface of Chrome DevTools. Its ability to edit files directly and blackbox external scripts improves productivity and focus during debugging sessions.

ndb automatically detects and attaches to child processes, simplifying debugging of multi-process Node.js applications without manual intervention, as highlighted in the features.
Allows setting breakpoints before modules are required, enabling early debugging in the module loading phase, an exclusive Node.js feature mentioned in the README.
Edit files directly within Chrome DevTools and save changes to disk using workspace functionality, improving productivity during debugging sessions, as described with a link to DevTools workspaces.
Includes sampling and memory profilers, plus a --prof flag for application profiling with restart capabilities, leveraging DevTools' advanced features for performance analysis.
Requires Puppeteer which downloads a large Chromium binary (170-280MB), increasing installation time and disk usage significantly, as noted in the installation section.
Global installation can fail due to permission errors, and Windows users may need to install additional build tools, complicating setup, as admitted in the README's troubleshooting notes.
Only supports Node.js 8.0.0 and above, with optimal performance on Node 10+, excluding older or legacy projects, which limits adoption in some environments.
