How to use this developer tool

  1. Paste Node.js or Express source into the input area.
  2. Select the analysis, conversion, formatting, or generation mode.
  3. Adjust the secondary option for the selected tool.
  4. Run the tool and review the status, output, metrics, and recommendation.
  5. Copy or download the result after checking heuristic findings.

What this developer tool does

Parse Node.js modules, dependencies, exports, functions, classes, environment variables, and asynchronous patterns without executing the source code.

Mask strings and comments → detect structural patterns → apply tool-specific rules → calculate live metrics → generate copy-ready output.

Static browser-based processing does not execute Node.js code, resolve installed packages, start a server, or access the project file system.

Example

The preloaded example is valid test input. Run the tool, change the source, and compare how the output and status respond.

Tips for better output

  • Use complete files when route order or module structure matters.
  • Disable auto-run for very large inputs.
  • Review heuristic findings against your actual Node.js version and package configuration.
  • Do not paste secrets, credentials, or private production data.

FAQ

How can I parse require and import statements from Node.js code?

Paste the source and run the parser. It identifies CommonJS require calls, ES module imports, dynamic imports, and classifies core, external, local, and JSON dependencies.

How do I find all exports in a Node.js file online?

The export map detects module.exports, exports properties, default exports, named exports, and basic re-export statements without executing the file.

How can I detect CommonJS and ES modules in the same file?

Choose automatic module detection. The report marks CommonJS, ES modules, or mixed syntax and lists the matching statements.

How do I extract process.env variables from Node.js source code?

Enable detailed or deep parsing. The environment section lists process.env property access and bracket notation when it can be identified statically.

Can I parse Node.js code without running it?

Yes. This browser tool treats source as text and performs static pattern analysis; it does not execute imports, packages, file access, or network requests.
