🧾 Barkit Input Scanner

A modular barcode scanner input manager with device support and action token handling, optimized for hardware integrations like Zebra and Datalogic.

Features

• CLI for quick scanner input capture / testing.
• Scan history & CSV export
• Runtime detection detects context and device apis if available (Datalogic device api is the only one currenly directly supported)
• Action tokens for scan-commands.
• Subscription-based output

Installation

yarn add barkit.io

CLI

Run the CLI directly with:

yarn dev

Or link to a bash alias using npm link:

# link using npm link
yarn link:cli

# then run
scanner-cli

# will output
[Scanner CLI] Waiting for input (Ctrl+C to exit)...

Usage

import Barkit from './input/index.js'

const scanner = new Barkit({ debug: true })
scanner.$subscribe(data => {
  console.log('Scanned:', data)
})

Generic API

The Generic device API will attach itself based on the current context.

Action Tokens

These values trigger internal Barkit utils when scanned:

| Token | Function | Behavior | |------------------------|-------------------------------------------|--------------------------| | __RESET_DEVICE__ | calls Barkit.reset() | Re-initializes the scanner | | __EXPORT_CSV__ | calls Barkit.exportFromScan() | Exports history to file and clears it | | __CLEAR_HISTORY__ | clears scan history | Clears the current scan history | | __CLEAR_BUFFER__ | explicitly clears current scan buffer | Resets buffered scan input |

💡 Scanner Support

Implemented

• Datalogic

Debug

Enable the debug overlay with debug: true:

const scanner = new Barkit({ debug: true })

Click to expand full current buffer state.

File Export

Export scan history to CSV:

scanner.exportFromScan('csv')

Or emit the __EXPORT_CSV__ token via scanner input.
