global.d.ts 無效

解決辦法

tsconfig.json

{
  "compilerOptions": {
    "typeRoots": ["./node_modules/@types/", "./custom/path/to/declarations/"]
  },
}

示例

例如，在根目錄下新建 types 目錄

types/global.d.ts

declare interface Window {
  opts: Object
}

tsconfig.json

{
  "compilerOptions": {
    "typeRoots": ["./node_modules/@types/", "./types/"]
  },
}
