ゴール: Custom query handlers in Puppeteer v24 are managed through the named customQueryHandlers registry export with strict alphabetic-only name validation HOW
パッケージ: puppeteer 24.43.1
環境: node
作成日: 2026-08-17T02:01:03Z

Custom query handlers in Puppeteer can be registered globally via puppeteer.registerCustomQueryHandler with hyphenated or snake_case names.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

puppeteer.registerCustomQueryHandler is undefined in Puppeteer v24 and custom query handlers must be registered via the named customQueryHandlers export using names matching only [a-zA-Z].
puppeteer.unregisterCustomQueryHandler and puppeteer.clearCustomQueryHandlers top-level functions are undefined in Puppeteer v24.
puppeteer.customQueryHandlers.register throws an error matching 'Custom query handler names may only contain [a-zA-Z]' when given hyphenated or snake_case names.
puppeteer.customQueryHandlers.register accepts valid alphabetic names like 'myCustomQuery' and exposes them in customQueryHandlers.names().
