/**
* This feature allows the distribution of a Node.js application conveniently to a
* system that does not have Node.js installed.
*
* Node.js supports the creation of [single executable applications](https://github.com/nodejs/single-executable) by allowing
* the injection of a blob prepared by Node.js, which can contain a bundled script,
* into the `node` binary. During start up, the program checks if anything has been
* injected. If the blob is found, it executes the script in the blob. Otherwise
* Node.js operates as it normally does.
*
* The single executable application feature currently only supports running a
* single embedded script using the `CommonJS` module system.
*
* Users can create a single executable application from their bundled script
* with the `node` binary itself and any tool which can inject resources into the
* binary.
*
* Here are the steps for creating a single executable application using one such
* tool, [postject](https://github.com/nodejs/postject):
*
* 1. Create a JavaScript file:
* ```bash
* echo 'console.log(`Hello, ${process.argv[2]}!`);' > hello.js
* ```
* 2. Create a configuration file building a blob that can be injected into the
* single executable application (see `Generating single executable preparation blobs` for details):
* ```bash
* echo '{ "main": "hello.js", "output": "sea-prep.blob" }' > sea-config.json
* ```
* 3. Generate the blob to be injected:
* ```bash
* node --experimental-sea-config sea-config.json
* ```
* 4. Create a copy of the `node` executable and name it according to your needs:
* * On systems other than Windows:
* ```bash
* cp $(command -v node) hello
* ```
* * On Windows:
* ```text
* node -e "require('fs').copyFileSync(process.execPath, 'hello.exe')"
* ```
* The `.exe` extension is necessary.
* 5. Remove the signature of the binary (macOS and Windows only):
* * On macOS:
* ```bash
* codesign --remove-signature hello
* ```
* * On Windows (optional):
* [signtool](https://learn.microsoft.com/en-us/windows/win32/seccrypto/signtool) can be used from the installed [Windows SDK](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/).
* If this step is
* skipped, ignore any signature-related warning from postject.
* ```powershell
* signtool remove /s hello.exe
* ```
* 6. Inject the blob into the copied binary by running `postject` with
* the following options:
* * `hello` / `hello.exe` \- The name of the copy of the `node` executable
* created in step 4.
* * `NODE_SEA_BLOB` \- The name of the resource / note / section in the binary
* where the contents of the blob will be stored.
* * `sea-prep.blob` \- The name of the blob created in step 1.
* * `--sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2` \- The [fuse](https://www.electronjs.org/docs/latest/tutorial/fuses) used by the Node.js project to detect if a file has been
* injected.
* * `--macho-segment-name NODE_SEA` (only needed on macOS) - The name of the
* segment in the binary where the contents of the blob will be
* stored.
* To summarize, here is the required command for each platform:
* * On Linux:
* ```bash
* npx postject hello NODE_SEA_BLOB sea-prep.blob \
* --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
* ```
* * On Windows - PowerShell:
* ```powershell
* npx postject hello.exe NODE_SEA_BLOB sea-prep.blob `
* --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
* ```
* * On Windows - Command Prompt:
* ```text
* npx postject hello.exe NODE_SEA_BLOB sea-prep.blob ^
* --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
* ```
* * On macOS:
* ```bash
* npx postject hello NODE_SEA_BLOB sea-prep.blob \
* --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \
* --macho-segment-name NODE_SEA
* ```
* 7. Sign the binary (macOS and Windows only):
* * On macOS:
* ```bash
* codesign --sign - hello
* ```
* * On Windows (optional):
* A certificate needs to be present for this to work. However, the unsigned
* binary would still be runnable.
* ```powershell
* signtool sign /fd SHA256 hello.exe
* ```
* 8. Run the binary:
* * On systems other than Windows
* ```console
* $ ./hello world
* Hello, world!
* ```
* * On Windows
* ```console
* $ .\hello.exe world
* Hello, world!
* ```

* @experimental
* @see [source](https://github.com/nodejs/node/blob/v24.x/src/node_sea.cc)
