javascript - 转到 Typescript Source Definition 而不是 Visual Studio Code 中的 Compiled Definition

Question

我正在使用 Visual Studio Code 开发一个 typescript 项目，包括多个结构如下的 npm 包:

• 源代码:/src/index.ts
• 编译后的代码:/dist/...

当我右键单击导入的对象并选择“转到定义”或单击 F12 或按住 CTRL 单击对象时，Visual Studio Code 打开/dist

中对应的 .d.ts文件

但是，我想让VSCode在/src中打开对应的.ts文件

是否可以更改此行为，因为手动搜索源文件真的很烦人。

我已经创建了 git repo，所以你可以自己试试: https://github.com/flolude/stackoverflow-typescript-go-to-definition

Answer 1

TypeScript 2.9 引入了一个名为 declarationMap 的编译器选项.根据发行说明:

Enabling --declarationMap alongside --declaration causes the compiler to emit .d.ts.map files alongside the output .d.ts files. Language Services can also now understand these map files, and uses them to map declaration-file based definition locations to their original source, when available.

In other words, hitting go-to-definition on a declaration from a .d.ts file generated with --declarationMap will take you to the source file (.ts) location where that declaration was defined, and not to the .d.ts.

我submitted a PR在您的示例存储库中启用此设置。
