[zimic] ✔ Generated ./src/types/github/typegen/generated.ts (3.06s)

Expected behavior

No deprecation warnings.

[diego-aquino]

This issue is not caused specifically by Zimic, but by whatwg-url through redocly-cli and openapi-typescript.

Related issues:

• punycode deprecation warning in node 21 Redocly/redocly-cli#1332
• punycode deprecated - still need? openapi-ts/openapi-typescript#1939
• Deprecation issue with the 'punycode' module jsdom/whatwg-url#278

For now, Zimic could dynamically import openapi-typescript, so that the warning only appears for zimic typegen openapi instead of all CLI commands.

For a complete fix, we have to wait for Redocly/redocly-cli#1332 and a transitive upgrade in openapi-typescript.

For now, Zimic could dynamically import openapi-typescript, so that the warning only appears for zimic typegen openapi instead of all CLI commands.

Dynamic import implemented in #460.

I'm marking this as blocked by Redocly/redocly-cli#1332 for the full fix.
