Docker build source files issue. API routes does not work.

Bug report

Describe the bug

I'm deploying fly.io using a docker build, compared to version 1.0 there are a few issues with the same production image. The API routes don't work unless the /src folder is commited on the production server (these are typescript files, not sure why that seems necessary).

After running medusa build only the /build folder is created, /dist is missing for some reason. Running locally the build script outputs the /dist folder, so not sure about that behavior.

Also, in the latest medusa release, x-publishable-api-key seems to have no effect if we commit the /src folder to access API routes.

System information

Medusa version (including plugins): v2.0.9-preview Node.js version: 22 Database: Postgres (sslmode disable) Operating system: Linux Browser (if relevant): Chrome

Also, after converting the config to the ES module, it doesn't seem to work in production (e.g. npx medusa db:migrate). Running locally works fine. It would be nice to have more info on how to properly bundle an app with Docker.

Error in loading config: This is caused by either a bug in Node.js or incorrect usage of Node.js internals.

before:

const { loadEnv, defineConfig, Modules } = require("@medusajs/utils");

loadEnv(process.env.NODE_ENV, process.cwd());

const config = defineConfig({
  projectConfig: {
    // ...
  },

  // ...
});

module.exports = config;

after:

import { loadEnv, defineConfig, Modules } from "@medusajs/utils";

loadEnv(process.env.NODE_ENV, process.cwd());

const config = defineConfig({
  projectConfig: {
    // ...
  },

  // ...
});

export default config;

Hey, it seems you are not copying the dist folder in the following copy commands.

COPY --from=builder /usr/src/app/package.json ./package.json
COPY --from=builder /usr/src/app/node_modules ./node_modules
COPY --from=builder /usr/src/app/build ./build

@thetutlage yeah, for some reason it wasn't generated with the /build folder, not sure why. Medusa 1.0 and the running locally Medusa 2.0 build script work fine. Maybe something wrong with default typescript configuration?

[predaytor]

It seems to work using similar setup for scripts from Medusa 1.0.

"scripts": {
  "clean": "cross-env ./node_modules/.bin/rimraf dist",
  "build": "cross-env npm run clean && medusa build && tsc -p tsconfig.json",
}

But without copying the ./src folder to the docker image, the API routes don't work:

Cannot GET /store/custom

Maybe we should do like this?

COPY --from=builder /usr/src/app/dist ./src
