If I had more time, I could improve many things, like:

• In the frontend:
  • The design of the page.
  • Show content instead of only a title.
  • Show images.
  • Make the page responsive to mobile devices.
  • Show a message when there are no recent posts to display.
  • Don't hit the endpoint that gets all the recent posts data when the user likes a post.
  • Don't allow the user to create posts with empty content, and show a proper message.
  • Clear the text in the input element of the 'Create post' component after the user created a post.
  • Fix the bug where the homepage looks bad when there are many posts.
  • Maybe disable action buttons ('Like' and 'Create post') after they're pressed and until the action they initiate finishes. This way the user can't spam the endpoints from the application.
  • Use a proper tool to provide styling to the components.
  • Create components to avoid repeating some style rules.
  • Allow the user to sort posts by creation date and/or likes.
  • Follow proper conventions for CSS styles implementation.
• In the backend:
  • Move the routes definition to a 'routes' folder.
  • Move the business logic of each endpoint to a 'services' folder.
  • Create controllers between routes and services to validate the data provided in the request.
  • Correctly return responses for error cases.
  • Maybe make success return responses follow a convention and/or be more descriptive.
  • Enforce very strict model definitions and make sure there's no way of inserting or updating rows with incorrect data.
  • Implement pagination for the GET endpoint.
• Overall:
  • Use TypeScript.
  • Add unit tests for the logic.
  • Add integration tests for simple scenarios.
  • Consider scaling problems.
  • Consider authentication.
