When interviewing for a position involving React with TypeScript, interviewers often request small projects or components that can be realistically implemented within an hour to test your coding skills, understanding of React concepts, and ability to use TypeScript effectively. Here are ten common mini-project ideas that might be requested in such an interview:

  1. To-Do List Application: Create a simple to-do list that allows users to add, remove, and toggle the completion status of tasks.

  2. Counter Application: Build a counter with increment, decrement, and reset functionality.

  3. Weather Widget: Develop a small widget that displays the current weather information for a hardcoded location (since API calls may not be possible).

  4. Calculator: Implement a basic calculator that can perform operations like addition, subtraction, multiplication, and division.

  5. Simple Blog Dashboard: Create a component that displays a list of blog posts with the ability to select a post to view more details.

  6. Timer or Stopwatch: Make a timer or stopwatch with start, stop, and reset controls.

  7. Data Table: Construct a table that displays a list of items with simple sorting and filtering capabilities.

  8. Form with Validation: Design a form with multiple inputs and implement client-side validation using TypeScript for type checking.

  9. Modal Component: Code a reusable modal component that can be opened and closed with a button click, with the content passed as children or props.

  10. Pagination Component: Build a component that displays a list of items with pagination controls.

Certainly, here are five more mini-project ideas suitable for an interview setting, focusing on React with TypeScript:

  1. Autocomplete Text Input: Create an input field that suggests completions as the user types. The suggestions could be a static list of terms.

  2. Theme Switcher: Implement a feature that allows users to switch between different UI themes (e.g., light mode and dark mode) across the application.

  3. Image Carousel: Build a simple image carousel that allows users to navigate through a series of images using previous and next buttons.

  4. Chat UI: Design a basic chat interface with a message input and a display area for messages. No backend is needed; just the UI components.

  5. Accordion Component: Code a collapsible accordion component where users can click on a section header to expand or collapse content.

Each of these projects would give you the chance to demonstrate your understanding of React components, state and effect hooks, conditional rendering, and TypeScript type annotations for props and state.
