Usage: electron-installer-dmg ./FooBar-darwin-x64/FooBar.app FooBar Options: --out= The directory to put the DMG into. [Default: `process.cwd()`]. --icon= Path to the icon file that will be the app icon in the DMG window. --icon-size= How big to make the icon for the app in the DMG. [Default: `80`]. --background= Path to a PNG image to use as the background of the DMG. [Size: 658 x 498] --title= The title of the produced DMG, which will be shown when mounted. --overwrite Overwrite any existing DMG. -h --help Show this screen. --version Show version. ``` ### API ```javascript const { createDMG } = require('electron-installer-dmg'); async function buildDMG() { await createDMG({ appPath: '/path/to/app.app', name: 'MyApp' }); } ``` #### createDMG(opts) ##### `opts` `appPath` - *String* - **Required** The `.app` directory generated by [electron-packager][electron-packager]. `name` - *String* - **Required** The application name. `title` - *String* The title of the produced DMG, which will be shown when mounted. `background` - *String* Path to the background for the DMG window. Background image should be of size 658 × 498. `icon` - *String* Path to the icon to use for the app in the DMG window. `iconSize` - *Number* How big to make the icon for the app in the DMG. [Default: `80`]. `overwrite` - *Boolean* Overwrite an existing DMG file if if already exists. `out` - *String* The directory to put the DMG into. [Default: `process.cwd()`]. `contents` - *Array* or *Function* that returns an Array of objects. The content that will appear in the window when user opens the `.dmg` file. [Default: Array of two icons, application and application destination folder]. Array example: ```javascript [ { x: 448, y: 344, type: 'link', path: '/Applications'}, { x: 192, y: 344, type: 'file', path: '/path/to/application.app'} ] ``` Function example (more flexible for getting useful options used in creating a DMG): ```javascript function (opts) { return [ { x: 448, y: 344, type: 'link', path: '/Applications'}, { x: 192, y: 344, type: 'file', path: opts.appPath} ]; } ``` `format` - *String* Disk image format. [Default: `UDZO`]. [Must be one of the following][spec]: - `UDRW` :arrow_right: read/write image - `UDRO` :arrow_right: read-only image - `UDCO` :arrow_right: ADC-compressed image - `UDZO` :arrow_right: zlib-compressed image - `UDBZ` :arrow_right: bzip2-compressed image - `ULFO` :arrow_right: lzfse-compressed image (macOS 10.11+ only) `additionalDMGOptions` - *Object* Additional options to pass through to [`appdmg`](https://npm.im/appdmg) You can use this to set additional features like `background-color` and `code-sign`. See the docs of the `appdmg` module for all possible options. ## License Apache 2.0 [actions_img]: https://github.com/electron-userland/electron-installer-dmg/actions/workflows/ci.yml/badge.svg [actions_url]: https://github.com/electron-userland/electron-installer-dmg/actions/workflows/ci.yml [npm_img]: https://img.shields.io/npm/v/electron-installer-dmg.svg [npm_url]: https://npm.im/electron-installer-dmg [electron-packager]: https://github.com/electron/electron-packager [appdmg]: https://github.com/LinusU/node-appdmg [spec]: https://github.com/LinusU/node-appdmg#specification ================================================ FILE: package.json ================================================ { "name": "electron-installer-dmg", "description": "Create DMG installers for your electron apps.", "version": "5.0.1", "main": "./dist/index.js", "typings": "./dist/index.d.ts", "author": "Lucas Hrabovsky (http://imlucas.com)", "homepage": "http://github.com/electron-userland/electron-installer-dmg", "repository": { "type": "git", "url": "git://github.com/electron-userland/electron-installer-dmg.git" }, "scripts": { "build": "tsc", "coverage": "nyc --reporter=lcov --reporter=text npm run spec", "lint": "eslint src test --ext js,ts", "spec": "ts-mocha test/*.test.ts", "test": "tsc && npm run lint && npm run spec", "prepublishOnly": "tsc" }, "bin": { "electron-installer-dmg": "dist/electron-installer-dmg-bin.js" }, "engines": { "node": ">= 16" }, "files": [ "dist", "resources", "usage.txt" ], "dependencies": { "@types/appdmg": "^0.5.5", "debug": "^4.3.2", "minimist": "^1.2.7" }, "optionalDependencies": { "appdmg": "^0.6.4" }, "license": "Apache-2.0", "devDependencies": { "@electron/get": "^2.0.2", "@types/debug": "^4.1.7", "@types/minimist": "^1.2.2", "@types/mocha": "^10.0.0", "@types/node": "^18.11.7", "@typescript-eslint/eslint-plugin": "6.21.0", "@typescript-eslint/parser": "6.21.0", "eslint": "^8.26.0", "eslint-config-airbnb-base": "^15.0.0", "eslint-plugin-import": "^2.23.4", "extract-zip": "^2.0.1", "mocha": "^9.0.3", "nyc": "^15.1.0", "ts-mocha": "^10.0.0", "typescript": "5.5.2" }, "keywords": [ "mongodb.js", "electron", "installer", "electron-installer", "gulpfriendly", "dmg", "electron create dmg" ] } ================================================ FILE: src/electron-installer-dmg-bin.ts ================================================ #!/usr/bin/env node /* eslint no-console:0 no-sync:0 */ import * as fs from 'fs'; import * as minimist from 'minimist'; import * as path from 'path'; import { createDMG, ElectronInstallerDMGOptions } from '.'; // eslint-disable-next-line @typescript-eslint/no-var-requires const pkg: { version: string } = require('../package.json'); const usage = fs.readFileSync(path.resolve(__dirname, '../usage.txt')).toString(); const args = minimist & { out?: string; 'icon-size'?: string; }>(process.argv.slice(2), { boolean: ['overwrite'], string: ['out', 'icon', 'icon-size', 'background', 'title', 'format'], }); const [appPath, name] = args._; const options: ElectronInstallerDMGOptions = { appPath, name, overwrite: args.overwrite, icon: args.icon, iconSize: args['icon-size'] ? parseInt(args['icon-size'], 10) : undefined, background: args.background, title: args.title, format: args.format, out: args.out, }; if (args.help || args.h || !options.appPath || !options.name) { console.error(usage); process.exit(1); } if (args.version) { console.error(pkg.version); process.exit(1); } createDMG(options) .then(() => { console.log(`Wrote DMG to:\n${args.dmgPath}`); }) .catch((err) => { console.error(err); process.exit(1); }); ================================================ FILE: src/index.ts ================================================ import type appdmgType from 'appdmg'; import debugCreator from 'debug'; import { existsSync, promises as fs } from 'fs'; import * as path from 'path'; const debug = debugCreator('electron-installer-dmg'); export type ElectronInstallerDMGOptions = { /** * The `.app` directory generated by Electron Packager. */ appPath: string; /** * The application name. */ name: string; /** * The title of the produced DMG, which will be shown when mounted. * * @defaultValue the {@link ElectronInstallerDMGOptions.name | application name} */ title?: string; /** * Path to the background image for the DMG window.
