Error [ERR_UNKNOWN_BUILTIN_MODULE]: No such built-in module: express

[MGMehdi]

Hello, I tried to compile my express app following the Single executable applications guide in but I've got this error :

node:internal/util/embedding:48
    throw new ERR_UNKNOWN_BUILTIN_MODULE(id);
    ^

Error [ERR_UNKNOWN_BUILTIN_MODULE]: No such built-in module: express
    at embedderRequire (node:internal/util/embedding:48:11)
    at dist/app.js:141:33
    at embedderRunCjs (node:internal/util/embedding:37:10)
    at node:internal/main/embedding:18:8 {
  code: 'ERR_UNKNOWN_BUILTIN_MODULE'
}

Node.js v21.6.0

It also appear with Node.js v20.10.0.

The app is written with typescript but the build is working when running in the terminal. Here is the tsconfig.json

{
  "compilerOptions": {
    "target": "ES5",
    "lib": ["ES5"],
    "module": "commonjs",
    "rootDir": "./src",
    "sourceMap": true,
    "outDir": "./dist",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "skipLibCheck": true
  }
}

Did I miss something ?

Yeah, the part where it says that it only supports built-in modules.

Yes, for now you would need to bundle your code into one single file that only requires builtins before injecting it into the SEA.

Hooo I didn't understand like that. Thanks for the clarification! For now if I want to achieve the same results is by using pkg by vercel?

FYI pkg has been archived now. I'm maintaining the most active fork here: https://github.com/yao-pkg/pkg

If you need ESM support there some alternatives: https://github.com/yao-pkg/pkg/issues/16#issuecomment-1945486658

This will works if you do a build with just one file. Install esbuild: npm install --save-exact --save-dev esbuild Copy to package.json:

     "scripts": {
     "build": "esbuild your-start-file.js --bundle --platform=node --outfile=out.js"
        }

generate out.js : npm run build Then resumes the whole process from https://nodejs.org/api/single-executable-applications.html for out.js

In my case I need to package a application that uses the serialport module. The compiled version throws the following error: Error: No native build was found for platform=win32 arch=x64 runtime=node abi=127 uv=1 libc=glibc node=22.2.0

I followed the steps you provided and successfully resolved a fast-csv built-in module not found issue. The generated exe runs without an error on Windows 10 64-bit.

@robertsLando I've tried your esbuild.js file, but it's not works for me :(, I'm having issue with usb package
