react-individual-character-input-boxes

React Individual Character Input Boxes (RICIBs) are individual inputs that are separate from each other but functionally act similar as a regular input box. Motivation came from Apple's similar input boxes used for their two-factor authorization:

Installation

$ npm i react-individual-character-input-boxes

How To Use

Import:

import RICIBs from 'react-individual-character-input-boxes';

Example code:

handleOutput (string) {
    // Do something with the string
  }

  render () {
    return (
      <div>
        <RICIBs
          amount={5}
          autoFocus
          handleOutputString={this.handleOutput}
          inputProps={
            { className: "2fa-box",
              style: { "color": "orange" },
              placeholder: "_"
            }
          inputRegExp={/^[0-9]$/}
        />
      </div>
    )
  }

Props:

Prop	Type	Required	Description
amount	Number		sets the number of input boxes. (default is 5)
autoFocus	Boolean		When true, the first input box will automatically be selected on page load. (default false)
handleOutputString	Function	✓	Implement it to handle the string output of the module.
inputProps	Object or Array<Object>		Allows you to pass through properties to the input boxes. With this you can customize attributes (including styles) for all of the boxes by using an Object. To customize each box individually use an array of objects where each item in the array represents a box.
inputRegExp	RegExp		Tells the component which characters to allow as inputs. (default is /^[0-9]$/ which is only numbers)
password	Boolean		Masks in the input if set as true (default is false)

Help, I cant get it to work or I want a feature!

Please feel free to submit an issue if you are running into trouble or have an idea for additional functionality!

BUG

I am aware that there is a bug where if you type extremely quickly, sometimes the selection will spazz out and jump between inputs. It happens very rarely though, only when you basically spam your keyboard as fast as you can. If you have any ideas on how to fix this please let me know!
