📝 Walkthrough

Walkthrough

The default Node.js major version constant is updated from 22 to 24 in packages/zip-it-and-ship-it/src/runtimes/node/utils/node_version.ts. This constant serves as the fallback when getNodeVersion receives no config version. The esbuild bundler target mapping in packages/zip-it-and-ship-it/src/runtimes/node/bundlers/esbuild/bundler_target.ts is extended with a new entry to map Node version 24 to the string 'node24', enabling the bundler to target Node 24. Unit test expectations in node_runtime.test.ts are updated to reflect that inputs without explicit versions now resolve to nodejs24.x instead of nodejs22.x. Integration test cases in v2api.test.ts for older and invalid Node version scenarios are updated to expect the nodejs24.x fallback.
