nodejs-sea-hide-passthrough

This a simple binary passthrough that hides the console window when a SEA (Single Executable Application) is opened. Useful when you want a simple nodejs SEA to run on the background and don't show any console windows. It also passes along every console argument through.

Usage

1. Download the latest release (nodejs-sea-hide-passthrough.exe and config.ini).
2. Place both files in the same directory as your Node.js SEA (or any other executable you want to hide).
3. Edit config.ini and set Target=YOUR_APP_NAME.exe.
4. Run nodejs-sea-hide-passthrough.exe. It will launch your app in a hidden window and pass all arguments to it.

Configuration (config.ini)

The behavior is controlled by config.ini:

[Settings]
; The name of the Single Executable Application (SEA) or binary to launch.
Target=helo.exe

Creating a Node.js Single Executable Application (SEA)

If you haven't created a Node.js SEA yet, here is a quick guide based on the official Node.js documentation.

1. Preparation

Create your JavaScript file (e.g., hello.js) and a configuration file sea-config.json:

hello.js

console.log(`Hello, ${process.argv[2]}!`);

sea-config.json

{
  "main": "hello.js",
  "output": "sea-prep.blob"
}

2. Generate the Blob

Run the following command to generate the sea-prep.blob:

node --experimental-sea-config sea-config.json

3. Create the Executable

Copy the node executable to your project folder.

Windows (PowerShell):

node -e "require('fs').copyFileSync(process.execPath, 'hello.exe')"

Linux/macOS:

cp $(command -v node) hello

4. Inject the Blob

Use postject to inject the blob into the executable.

npx postject hello.exe NODE_SEA_BLOB sea-prep.blob --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2

(On macOS, add --macho-segment-name NODE_SEA)

Now you have a standalone hello.exe! You can use this nodejs-sea-hide-passthrough tool to wrap it and hide the console window.
