This exercise is designed to assess how you approach tasks required in your position as an intermediate developer at silverorange. We are interested to see how you work as well, as what your final results are; include useful Git commit messages and comments where you think your code may be unclear.

Please do not include your name or any other self-identifying information in code or commit messages as silverorange will anonymize your work before reviewing.

Using the provided React application in /web:

1. Fetch post data from the provided Express API.
2. Display a list of posts. Include the post title, summary, author, and publish date in the list.
3. The list of posts should be displayed in reverse chronological order.
4. Also list each unique author. Make clicking an author filter the list of posts by the selected author.
5. Make the title of each post in the list clickable. When you click a post title, display the formatted post body and title. The post body is formatted as Markdown and the post display should use the formatted Markdown.
6. Implement basic snapshot regression tests tests using Jest for your components. Jest is installed by create-react-app and can be run from the web/ folder with yarn test.

You can use any stable version of Node JS. The base project is written using TypeScript but you may use vanilla JavaScript to complete the tasks.

Please use ESLint and Prettier for your code. The project is set up to lint your code using:

yarn lint

If your editor is not already configured to use Prettier, you can format code in the project using:

yarn prettier-write

Please use the Yarn or NPM tools for dependency management. You can use any 3rd-party libraries as necessary or as desired in order to achieve the tasks. The project is currently set up to use Yarn but you may update it to use NPM if that is your preference.

Your commit history is important to us! Try to make meaningful commit messages that show your progress. Remember to not include your name or any other self-identifying information in your commit messages.

For this exercise a pre-built Express application is provided. The application runs by default on localhost:4000 and has the following endpoints:

• http://localhost:4000/posts - returns a JSON-encoded array of blog posts.

cd api/
yarn install
yarn start

You can verify the API is working by visiting http://localhost:4000/posts in your browser or another HTTP client. Please note that about 25% of the time, the API returns an error message.

The React client is a bare Create React App application.

cd web/
yarn install
yarn start

This will open your browser at http://localhost:3000, allowing you to test the React client.
