Common Node.js Errors Explained
Node.js powers millions of applications, but debugging errors can be frustrating. This tool helps you understand and fix common issues quickly.
ESM/CommonJS Errors
ERR_REQUIRE_ESM and Cannot use import statement are increasingly common as packages migrate to ES Modules. Solutions include using dynamic imports, adding "type": "module" to package.json, or downgrading packages.
Module Resolution Errors
Cannot find module and MODULE_NOT_FOUND usually mean a package isn't installed or the path is wrong. Check your node_modules, verify package.json, and ensure correct file extensions in ESM mode.
Memory Errors
JavaScript heap out of memory occurs when Node.js runs out of RAM. Increase heap size with --max-old-space-size=4096, use streams for large files, or investigate memory leaks with clinic.js.
Network Errors
EADDRINUSE means the port is taken - find and kill the process.ECONNREFUSED means the target server isn't running.ETIMEDOUT indicates slow connections or firewall issues.
File System Errors
ENOENT means file not found - check paths and case sensitivity.EACCES/EPERM are permission issues - avoid sudo with npm and use nvm for Node.js installation.
