Cant install @types/node by docker RUN inside docker file

When I use the following Dockerfile:

FROM node:22-alpine

ENV NODE_ENV production

WORKDIR /usr/web-server

RUN npm i -g @nestjs/cli typescript

COPY ./package*.json ./

RUN npm install
RUN npm install @types/node

COPY ./ ./

EXPOSE 4000

CMD npm run start:dev

inside /usr/web-server/node_modules/@types node folder not installed.

However, if I use the Dockerfile below:

FROM node:22-alpine

ENV NODE_ENV production

WORKDIR /usr/web-server

RUN npm i -g @nestjs/cli typescript

COPY ./package*.json ./
RUN npm install
RUN npm uninstall @types/node
RUN npm install @types/node

COPY ./ ./

EXPOSE 4000

CMD npm run start:dev

evrething work fine.

Why in first Dockerfile
RUN npm install @types/node
dont install node folder inside @types?

I try to RUN npm install @types/node after COPY ./ ./
it doesn’t work either

    I this case it doesn't work in the first Dockerfile because @type/node was installed like dev dependency in package.json

    "devDependencies": {
   "@types/node": "^20.12.12",
}

    When i install it like RUN npm install @types/node inside Dockerfile, it doesn't add node folder inside @types in node_modules, because @types/node not istalled if it like devDependeces package.

    When jumping into the Docker container:

    cd /usr/web-server/node_modules/@types
ls 
// result empty folder

    However, when i uninstall it and install it again as main dependency, it work fine:

    cd /usr/web-server/node_modules/@types
ls 
// Now result is node folder

    thats why the second Docker file is worked fine

    and if i add packege @type/node like main dependence in package.json file:

    "dependencies": {
   "@types/node": "^20.12.12",
}

    Now I dont need to add RUN npm install/unistall @types/node in Dockerfile.

    The remaining question is why @types/node is not installed in the container as a devDependency, but that's another issue already.


  2. 0

    Are you sure that you don’t have a conflicting version of @types/node specified in your package.json? Suppose, for example, that you had this specified in package.json:

    "@types/node": "^16.0.0"

    Install from Dockerfile

    Something like this will enable you to install from the Dockerfile without first uninstalling.

    🗎 Dockerfile

    FROM node:22-alpine

ENV NODE_ENV production

WORKDIR /usr/web-server

RUN npm i -g @nestjs/cli typescript

COPY ./package*.json ./
RUN npm install
RUN npm install @types/node

COPY ./ ./

EXPOSE 4000

CMD npm run start:dev

    🗎 package.json (Note that this doesn’t contain @types/node, @nestjs/cli or typescript, all of which are being installed from the Dockerfile!)

      "name": "nestjs-web-server",
  "version": "1.0.0",
  "description": "A simple NestJS web server",
  "main": "src/main.ts",
  "scripts": {
    "start:dev": "nest start --watch"
  },
  "dependencies": {
    "@nestjs/common": "^9.0.0",
    "@nestjs/core": "^9.0.0",
    "@nestjs/platform-express": "^9.0.0"
  },
  "devDependencies": {
    "@nestjs/testing": "^9.0.0",
    "prettier": "^2.7.1",
    "eslint": "^8.15.0",
    "jest": "^29.0.0"
  }
}

    Install from package.json

    IMHO a better option is to move the package installation completely to package.json. With the setup below all packages are installed in a single npm install command.

    🗎 Dockerfile

    FROM node:22-alpine

ENV NODE_ENV production

WORKDIR /usr/web-server

COPY ./package*.json ./
RUN npm install

COPY ./ ./

EXPOSE 4000

CMD npm run start:dev

    🗎 package.json

    {
  "name": "nestjs-web-server",
  "version": "1.0.0",
  "description": "A simple NestJS web server",
  "main": "src/main.ts",
  "scripts": {
    "start:dev": "npx nest start --watch"
  },
  "dependencies": {
    "@nestjs/common": "^9.0.0",
    "@nestjs/core": "^9.0.0",
    "@nestjs/cli": "^9.0.0",
    "@nestjs/platform-express": "^9.0.0"
  },
  "devDependencies": {
    "@nestjs/testing": "^9.0.0",
    "@types/node": "^20.0.0",
    "typescript": "^4.6.3",
    "prettier": "^2.7.1",
    "eslint": "^8.15.0",
    "jest": "^29.0.0"
  }
}
