SEA: how package node_module into single-executable-applications?

[seepine]

package.json

{
  // ...
  "dependencies": {
    "fastify": "~4.26.2"
  }
}

hello.js

const fastify = require('fastify')({ logger: true })
fastify.route({
    url: '/',
    method: ['GET', 'POST'],
    handler: async function (req, reply) {
        return {
            "status": "UP"
        }
    }
})
fastify.listen({ port: 3000, host: '0.0.0.0' })

sea-config.json

{
    "main": "hello.js",
    "output": "hello.blob"
}

sea package sh

node --experimental-sea-config sea-config.json
cp $(command -v node) hello
npx postject hello NODE_SEA_BLOB hello.blob \
    --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2

run

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

From the documentation require(id) in the injected main script is not file based.

You'd have to first bundle your app into a single .js file using a tool like esbuild.
