• Automatic box width adjustment for the current terminal width
• Automatic line breaking for long text

Installation

Use npm.

npm install tty-width-frame

API

const ttyWidthFrame = require('tty-width-frame');

ttyWidthFrame(input)

input: string
Return: string

// When the terminal width is 30
 
ttyWidthFrame('abcdefghijklmnopqrstuvwxyz');
/* =>
  ┌────────────────────────┐
  │                        │
  │ abcdefghijklmnopqrstuv │
  │ wxyz                   │
  │                        │
  └────────────────────────┘
*/
 
// When the terminal width is 20
 
ttyWidthFrame('abcdefghijklmnopqrstuvwxyz');
/* =>
  ┌──────────────┐
  │              │
  │ abcdefghijkl │
  │ mnopqrstuvwx │
  │ yz           │
  │              │
  └──────────────┘
*/

When the terminal window is too narrow, or more specifically, its width is less than 15, it just returns the original string.

// When the terminal width is 14
 
ttyWidthFrame('abcdefghijklmnopqrstuvwxyz'); //=> 'abcdefghijklmnopqrstuvwxyz'

On a non-interactive script, it throws an Error instead.
