__dirname

Base directory for binary executable paths

Overview

The OpenComicAI.__dirname static property stores the base directory used to resolve paths to binary executables.

Type

static __dirname: string

Default value

Automatically set to the package’s installation directory. Uses __dirname in CommonJS environments or import.meta.dirname in ES modules.

Purpose

This property is used internally to locate platform-specific binary executables (realcugan, waifu2x, upscayl) included with the package.

Setting custom dirname

You can override the default directory using setDirname():

import OpenComicAI from '@opencomic/ai-bin';

// Set custom dirname
OpenComicAI.setDirname('/custom/path/to/binaries');

console.log(OpenComicAI.__dirname); // '/custom/path/to/binaries'

Example usage

import OpenComicAI from '@opencomic/ai-bin';
import path from 'path';

// Get current dirname
console.log(OpenComicAI.__dirname);
// /Users/username/node_modules/@opencomic/ai-bin/dist

// Set custom dirname for portable installation
const appPath = process.env.PORTABLE_EXECUTABLE_DIR || __dirname;
OpenComicAI.setDirname(appPath);

// The binary paths are now resolved from the custom dirname
const binary = OpenComicAI.binary('realcugan');
console.log(binary);
// /custom/path/to/binaries/../mac/arm64/realcugan/realcugan-ncnn-vulkan.app

Use cases

Portable applications

// For Electron apps with custom binary locations
const { app } = require('electron');
const resourcesPath = path.join(app.getAppPath(), 'resources');
OpenComicAI.setDirname(resourcesPath);

Development vs production

if (process.env.NODE_ENV === 'development') {
  // Use local build directory in development
  OpenComicAI.setDirname('./build');
} else {
  // Use package directory in production (default)
  // No need to set dirname
}

Custom binary distribution

// If you're bundling binaries separately
const binaryPath = process.env.OPENCOMIC_BINARY_PATH || 
  path.join(process.cwd(), 'binaries');
OpenComicAI.setDirname(binaryPath);

How it’s used internally

The __dirname property is used by the binary() method to construct full paths to executables:

// Internal usage example
const binary = OpenComicAI.binary('realcugan');
// Constructs: path.join(__dirname, '..', 'mac/arm64/realcugan/realcugan-ncnn-vulkan.app')

Path resolution

// setDirname converts relative paths to absolute paths
OpenComicAI.setDirname('./binaries'); // Converts to absolute path

// Absolute paths are used as-is
OpenComicAI.setDirname('/usr/local/opencomic/binaries');
