+# Single executable applications (https://nodejs.org/api/single-executable-applications.html)
+# This feature allows the distribution of a Node.js application conveniently to a system that does not have Node.js installed.
+
+# 3. Generate the blob to be injected
+
+node --experimental-sea-config sea-config.json
+
+# 4. Create a copy of the node executable and name it according to your needs
+
+cp $(command -v node) guida
+
+# node -e "require('fs').copyFileSync(process.execPath, 'hello.exe')" # On windows
+
+# 5. Remove the signature of the binary (macOS and Windows only)
+
+codesign --remove-signature guida # On mac
+
+# signtool remove /s guida.exe # On Windows (optional)
+
+# 6. Inject the blob into the copied binary by running postject with the following options
+
+# Linux
+# npx postject guida NODE_SEA_BLOB sea-prep.blob \
+#     --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
+
+# On Windows - PowerShell
+# npx postject guida.exe NODE_SEA_BLOB sea-prep.blob `
+#     --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2

+# npx postject guida.exe NODE_SEA_BLOB sea-prep.blob ^
+#     --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2

+
+# On macOS
+codesign --sign - guida
+
+# On Windows (optional)
+# A certificate needs to be present for this to work. However, the unsigned binary would still be runnable.
