# Node.js 18.16.0 Single Executable Applications (SEA)

Nifty. Hope we can get the file size down:

```

.rwxr-xr-x@  82M  hello

```

For what it's worth this is on par with a compiled Deno binary.

## macOS process

Make sure you've got Node.js 18.16.0 installed.

```sh

echo 'console.log(`Hello, ${process.argv[2]}!`);' > hello.js

```

```sh

cp $(command -v node) hello

```

```sh

codesign --remove-signature hello

```

```sh

npx postject hello NODE_JS_CODE hello.js \

  --sentinel-fuse NODE_JS_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \

  --macho-segment-name NODE_JS

```

```sh

codesign --sign - hello

```

```sh

./hello world

```

♠️

## v19 (unreleased)

Make use of the `--experimental-sea-config` flag to generate the binary blob ahead of injection.

Example config in sea-config.json:

```json

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

```
