Install

Install with npm:

$ npm install --save open-linux-file-dialog

Usage

HEADS UP!: On Linux, you need at least one of these file dialog tools installed:

• zenity (GNOME)
• kdialog (KDE)
• yad (Yet Another Dialog)
• qarma (Qt-based)
• matedialog (MATE)
• rofi (window switcher with file browser mode)
• fzf (terminal fuzzy finder)
• dmenu (dynamic menu)

On macOS, native dialogs are supported via osascript.

import { openLinuxFileDialog, getAvailableDialogTools } from 'open-linux-file-dialog';
// or
import openLinuxFileDialog from 'open-linux-file-dialog';

API

openLinuxFileDialog

Opens a file dialog to select files and returns the paths of selected files.

export const openLinuxFileDialog = async (
  initialDirectory?: string,
  options?: FileDialogOptions
): Promise<string[]>;

interface FileDialogOptions {
  multiple?: boolean;    // Allow multiple file selection
  title?: string;       // Dialog window title
  fileTypes?: string[]; // File type filters (e.g., ['*.txt', '*.md'])
}

Basic usage:

// Open the dialog in the current working directory
const selectedFiles = await openLinuxFileDialog();
console.log('Selected files:', selectedFiles);

Parameters:

initialDirectory (optional)

• Type: string
• Default: process.cwd()
• Sets the initial directory where the file dialog opens, allowing users to navigate from there.

const selectedFiles = await openLinuxFileDialog('/home/user/documents');

Other examples:

• openLinuxFileDialog() - Opens in current working directory
• openLinuxFileDialog('/home/user/Documents') - Opens in Documents folder, but user can navigate anywhere
• openLinuxFileDialog('/tmp') - Opens in /tmp directory

options (optional)

• Type: FileDialogOptions
• Configuration options for the file dialog

// Select multiple files with filters
const selectedFiles = await openLinuxFileDialog('/home/user', {
  multiple: true,
  title: 'Select configuration files',
  fileTypes: ['*.json', '*.yaml', '*.yml']
});

// Single file selection with custom title
const selectedFiles = await openLinuxFileDialog('/home/user', {
  title: 'Choose a document'
});

Returns:

• Type: Promise<string[]>
• An array of absolute file paths selected by the user
• Returns an empty array if the user cancels the dialog

Error handling:

try {
  const files = await openLinuxFileDialog();
  if (files.length === 0) {
    console.log('User cancelled the dialog');
  } else {
    console.log('Selected files:', files);
  }
} catch (error) {
  if (error instanceof FileDialogError) {
    console.error('File dialog error:', error.message);
  }
}

getAvailableDialogTools

Check which dialog tools are available on the system.

export const getAvailableDialogTools = async (): Promise<string[]>;

Usage:

const availableTools = await getAvailableDialogTools();
console.log('Available dialog tools:', availableTools);
// Output: ['zenity', 'kdialog', 'fzf']

Examples

Select multiple image files

const images = await openLinuxFileDialog('/home/user/Pictures', {
  multiple: true,
  title: 'Select images',
  fileTypes: ['*.jpg', '*.jpeg', '*.png', '*.gif']
});

Select a single configuration file

const [configFile] = await openLinuxFileDialog('/etc', {
  title: 'Select configuration',
  fileTypes: ['*.conf', '*.cfg']
});

if (configFile) {
  console.log('Selected config:', configFile);
}

Check for dialog tool availability

const tools = await getAvailableDialogTools();
if (tools.length === 0) {
  console.error('No file dialog tools found. Please install zenity, kdialog, or another supported tool.');
}

Notes

• The library automatically detects and uses the first available dialog tool
• GUI-based tools (zenity, kdialog, etc.) are preferred over terminal-based tools
• All returned paths are absolute paths
• File type filters are supported by most GUI dialog tools but may not work with terminal-based tools (fzf, dmenu)
• On macOS, the native file dialog is used via osascript
