webkitSpeechRecognition の型定義の書き方

Posted at

keyword: vendor prefix, ベンダープレフィックス

型定義ファイル書くの慣れてなくてちょっと迷ったので記録。
webkit接頭辞がないと使えないが、webkit付きだと型定義が存在しないようなSpeechRecognitionなどは以下を書くことで型が通る。

declare const webkitSpeechRecognition: typeof SpeechRecognition
declare const webkitSpeechGrammarList: typeof SpeechGrammarList
