npm i -S react-component-console

or

yarn add react-component-console
  1. Use it in your React app
import Console from 'react-component-console';
// ...
 
class MyComponent extends React.Component {
  // ...
 
  render() {
    return (

        'Hi!',
        'How are you today?'
      ]} />
    );
  }
}
 
export default MyComponent;

Customize

The following properties let you customize component behaviour.

  • lines: The the text to write.
  • callbacks: Supply callbacks for written line(s).
  • console: Customize Console behaviour.
    • append: Whether or not to append lines.
    • typing: Customize how the Console types text.
      • char: Customize how the Console types single characters.
      • line: Customize how the Console handles line breaks.
    • styling/CSS classes: Customize CSS class names to use for the Console component.
  • line: Customize the Line component.
  • ps1: Customize the PS1 component.
  • cursor: Customize the Cursor component.

Lines lines

Specify the string or array of strings to write.

Example

<Console lines={[
  'Hi!',
  'How are you today?'
]} />

Callbacks

onFinishWritingLine

Provide a callback which is called for every line that was written. The callback receives the line as parameter.

Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  onFinishWritingLine={
    (line) => {
      console.info('Console has finished writing line', line);
    }
  }
/>

onFinishWritingLines

Provide a callback which is called when all lines have been written. The callback receives the lines as parameter.

Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  onFinishWritingLines={
    (lines) => {
      console.info('Console has finished writing all lines', line);
    }
  }
/>

Console console

The console property lets you customize console behaviour.

Appending console.append

Set this property to true to append lines instead of writing them one by one.

Typing console.typing

react-component-console features highly cusomizable human-like typing behaviour. The following options let you fine tune typing the way you want.

console.typing.char

This object lets you specify typing behaviour concerning a single character. For every character a new delay is calculated depending on the average character delay and a deviation. If you, e.g. specify an average delay of 100ms and a deviation of 0.2 (or 20%), you end up with character typing delays between 80ms and 120ms.

Signature
{
  avgMs: 150, // average milliseconds to type a character
  deviation: 0.3, // deviation to apply to avgMs
  minMs: 50, // minimum milliseconds to type a character
  maxMs: Number.MAX_SAFE_INTEGER // maximum milliseconds to type a character
}
Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  console={{
    typing: {
      char: {
        avgMs: 100, // 100 ms average time to write a character
        deviation: 0.2, // deviate typing delay by 20 %
        minMs: 80 // take at least 80ms to write a character
      }
    }
  }}
/>

console.typing.line

This object lets you specify details concerning typing of a line. It works analogous to console.typing.char in the sense that you specify the average delay between lines (i.e. how long it takes to hit the return button) and a deviation from this average.

Signature
{
  delay: {
    avgMs: 1000, // average delay between lines in milliseconds, i.e. time to hit return
    deviation: 0.3, // deviation to apply to avgMs
    minMs: 50, // minimum delay between lines in milliseconds
    maxMs: Number.MAX_SAFE_INTEGER // maximum delay between lines in milliseconds
}
Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  console={{
    typing: {
      line: {
        avgMs: 600, // 600 ms average delay between lines
        deviation: 0.2, // deviate line delay by 20 %
        minMs: 500 // delay at least by 500ms to between lines
      }
    }
  }}
/>

Styles/CSS-classes

The Console component uses standard CSS classes for styles. You can overwrite any styles in your own stylesheets and you can supply your own class names as well.

console.classes

<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  console={{
    classes: {
      element: 'My-Console' // use .My-Console instead of the default .Console class name
    }
  }}
/>

Line

  }
}
Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  line={{

<Console
  lines={[
    'Hi!',
    'How are you today?'

  ps1={{

    }
  }}
/>

Content

ps1.content

Use this property to customize the PS1 content rendered in the Console.

Signature
{
  content: '$' // display a dollar sign as PS1

<Console
  lines={[
    'Hi!',
    'How are you today?'

    content: '~' // display a tilde instead of the default dollar sign
  }}
/>

Cursor

The cursor property lets you customize the Cursor component rendered in the Console.

Styles/CSS classes

  classes: {
    blink: 'Console-Cursor--blink', // class name to assign when the Cursor is blinking
    element: 'Console-Cursor', // class name to assign to the Cursor component
    write: 'Console-Cursor--write' // class name to assign when the Cursor is in writing state
  }
}
Example
<Console
  lines={[
    'Hi!',
    'How are you today?'
  ]}
  cursor={{
    classes: {
      blink: 'My-Console-Cursor--isBlinking', // use this instead of the default for blinking state
      element: 'My-Console-Cursor', // use this instead of the default for the Cursor component
      write: 'My-Console-Cursor--isWriting' // use this instead of the default for writing state
    }
  }}
/>

Use this property to specify how rapidly the Cursor should blink.

Signature
{
  intervalMs: 400 // blink for 400ms on and off

    'How are you today?'
  ]}
  cursor={{
    intervalMs: 250 // blink faster then the default 400ms
  }}
/>
