Root Cause

Built-in punycode module deprecated. Usually caused by a dependency, not your code.

generic

Workarounds

  1. 88% success Install the userland punycode package: npm install punycode 
    npm install punycode

    Sources: https://www.npmjs.com/package/punycode

  2. 90% success Update the dependency that uses punycode — check npm ls punycode 
    npm ls punycode  # find which dependency uses it
npm update <dep>

    Sources: https://nodejs.org/api/deprecations.html#DEP0040

  3. 85% success This is a warning, not an error — it still works, just update when possible 
    // Safe to ignore for now. Suppress in scripts if needed:
// NODE_OPTIONS='--no-warnings' node app.js
// But do plan to update the offending dependency

Dead Ends

Common approaches that don't work:

  1. Suppress the warning with --no-deprecation 70% fail

    Hides all deprecation warnings, including important ones

  2. Patch the dependency to remove punycode 80% fail

    Fragile and will be overwritten on npm install
