How do I import react-admin in a React Typescript appplication?

Current version of react-admin does not export types definition. To make your project to compile you need to create index.d.ts file and modify tsconfig.json.

├── @types
│   └── react-admin
│       └── index.d.ts
└── tsconfig.json

// tsconfig.json

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

// index.d.ts
declare module 'react-admin';
