Purpose

This repo tests the ability to import and use components from the fluent-ui-react library. It demonstrates a bug with the library not including the right type definitions by default.

Repro Steps

1. Clone this repository locally.
2. Make sure yarn is installed (if it isn't run npm install -g yarn).
3. Run yarn to install dependencies.
4. Run yarn start to build the project and run it at http://localhost:1234. This will also run tsc to perform type checking. (You can also run yarn run check to run tsc by itself).

Result:

The project builds and runs fine (showing a simple <Button> component). However, tsc complains:

  Try `npm install @types/lodash` if it exists or add a new declaration (.d.ts) file containing `declare module 'lodash';`

This error can be fixed if you manually install @types/lodash (by running yarn add @types/lodash -D). However, for a good developer experience, this shouldn't be necessary - (perhaps @types/lodash should be among the dependencies of the package, or included through some other build mechanism).
