Installation

Install package with NPM or YARN and add it to your development dependencies:

npm install react-terminal

yarn add react-terminal

Usage

import { ReactTerminal } from "react-terminal";

function App(props) {
  // Define commands here
  const commands = {
    whoami: "jackharper",
    cd: (directory) => `changed path to ${directory}`
  };

  return (
    <ReactTerminal
      commands={commands}
    />
  );
}

Also make sure to wrap the main mountpoint around the TerminalContextProvider. This retains the state even when the component is unmounted and then mounted back:

import { TerminalContextProvider } from "react-terminal";

ReactDOM.render(
  <TerminalContextProvider>
    <App/>
  </TerminalContextProvider>,
  rootElement
);

Creating custom themes

The component comes with few in-built themes: light, dark, material-light, material-dark, material-ocean, matrix and dracula. You can also create custom themes by passing themes parameter in props, as follows:

<ReactTerminal
  commands={commands}
  themes={{
    "my-custom-theme": {
      themeBGColor: "#272B36",
      themeToolbarColor: "#DBDBDB",
      themeColor: "#FFFEFC",
      themePromptColor: "#a917a8"
    }
  }}
  theme="my-custom-theme"
/>
