Pull request overview

Fixes a TypeScript types regression for ProgressPlugin.createDefaultHandler by aligning the generated declaration with the actual optionality of the progressBar argument in the implementation.

Changes:

  • Mark ProgressPlugin.createDefaultHandler’s progressBar parameter as optional in the generated types.d.ts.
  • Update the JSDoc in lib/ProgressPlugin.js to express that progressBar is optional (false=), which drives the generated typings.

Reviewed changes

Copilot reviewed 1 out of 2 changed files in this pull request and generated no comments.

File Description
types.d.ts Updates the generated createDefaultHandler signature so progressBar is optional (progressBar?: ...).
lib/ProgressPlugin.js Adjusts JSDoc to make progressBar optional, matching runtime behavior and enabling correct type generation.
