          echo: {
            description: 'Echo',
            fn: (...args) => {
              return new Promise((resolve, reject) => {
                setTimeout(() => {
                  resolve(`${args.join(' ')}`)
                }, 2000)
              })
            }
          },
          test: {
            description: 'Test',
            fn: (...args) => {
              return new Promise((resolve, reject) => {
                setTimeout(() => {
                  resolve('Hello world \n\n hello \n')
                }, 2000)
              })
            }
          }
        }}
      />
    </div>
  )
}
export default App

History implementation

You can provide your own history implementation by providing onAddHistoryItem and history properties. If you don't provide history, up/down arrows & reverse search won't work.
