const commands = {
  'greet': () => 'Hello, world!',
  'date': () => new Date().toString(),
};

function App() {
  return (
    <Terminal commands={commands} />
  );
}

export default App;

Understanding Commands and User Inputs in Terminal

In the above code, a command is an object where each key-value pair represents a command and its corresponding action. When a user enters a command in the terminal, the action associated with that command is executed.

Handling Unidentified Commands and Error Messages

If a user enters an unidentified command, we can display a custom error message.

  'default': () => 'Unidentified command executed',
};

      welcomeMessage="Welcome to my custom terminal!"
      prompt="my-terminal> "
    />
  );
}

Creating Custom Themes in React Terminal UI

Creating custom themes in React Terminal UI involves passing a theme parameter to the Terminal component. This parameter should be an object where each key-value pair represents a CSS property and its value.

};

function App() {
  return (
    <Terminal
      commands={commands}
      theme={myCustomTheme}
    />
  );
}

Passing Themes Parameter: A Detailed Guide

In the above code, a theme is a prop that accepts either a string representing one of the in-built themes or an object representing a custom theme.

Understanding Key-Value Pair in Custom Themes

Each key-value pair in the theme object represents a CSS property and its value. The keys should be in camelCase format.

Control Buttons and Top Bar: Enhancing User Experience

You can display control buttons and a top bar in your terminal by setting the showControlButtons prop to true.
