dockerised react.js app, module not found

Issue

I need to dockerize my react app, but incurring in some troubles:

Compiled with problems:

here’s my dockerfile:

FROM node:13.12.0-alpine

# set working directory
WORKDIR /app

# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH

# install app dependencies
COPY package.json ./
COPY package-lock.json ./
RUN npm install
RUN npm install react-scripts@latest -g
run npm build

# add app
COPY . ./

# start app
CMD ["npm", "start"]

here’s my docker-compose

version: '3.3'

services:
  propoly:
    build: .
    ports:
      - 3002:3002

here’s my package.json:

{
  "name": "insurance_microfrontend",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@apollo/client": "^3.5.6",

  },
  "eslintConfig": {

    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

Solution

graphql is not listed in your package.json

Run npm i --save graphql, then rebuild your Docker container.

This should fix the error.
