Item 66: Understand the Three Versions Involved in Type Declarations

要点

• There are three versions involved in an @types dependency: the library version, the @types version, and the TypeScript version.
• Recognize the symptoms of different types of version mismatch.
• If you update a library, make sure you update the corresponding @types.
• Understand the pros and cons of bundling types versus publishing them on DefinitelyTyped. Prefer bundling types if your library is written in TypeScript, and DefinitelyTyped if it is not.
• 一个 @types 依赖涉及三个版本：库版本、@types 版本和 TypeScript 版本。
• 识别不同类型版本不匹配的症状。
• 如果更新了库，确保更新相应的 @types。
• 理解将类型捆绑与发布到 DefinitelyTyped 的优缺点。如果你的库是用 TypeScript 编写的，优先选择捆绑类型；如果不是，优先选择发布到 DefinitelyTyped。
