Unable to run node.js app through Docker container

Question

I have a node.js application which I am trying to run in docker. Here is the package.json file snippet.

"main": "lib/server.js",
  "scripts": {
    "clean": "cross-env rm -rf dist",
    "build": "cross-env babel lib -d dist",
    "start": "npm run clean && npm run build && npm run serve",
    "serve": "node dist/index.js",
    "dev": "cross-env NODE_ENV=development nodemon lib/server.js --exec babel-node",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lint": "eslint --ext .js lib/ scripts/ --ignore-pattern node_modules/"
  }

And here is the Dockerfile to build the image

#---- Base Node------
FROM node:10.15.1-alpine

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

COPY package*.json ./

COPY lib ./lib

RUN npm install --only=production && npm run build

EXPOSE 4201

CMD ["npm", "run", "serve"]

I get the following error when I try to run the image. Here is the screenshot of the error.

The node and npm version are the same on my machine and the base image that I am using to build my image. When I run the same command locally in my machine it works Here is the exact command that I am running on my machine and it works.

npm install --only=production

npm run build

npm run serve

Am I doing something wrong here ? Any help is appreciated.

Answer 1

You are using ES6 imports

import x from package

In order to do that, you should have Babel package installed, otherwise it won't know how to import that file
