Tsc command giving error using docker file

Open Source Projects DockerEngine
1

I was running this code from the docker file to generate converted js files from the typescript code.

FROM node:18.3.0
WORKDIR /src
COPY package*.json ./
COPY tsconfig.json ./
RUN npm install
RUN tsc
COPY . ./
EXPOSE 5000
CMD ["npm", "run", "start"]

However, it shows the follow error on running docker build:-

image

here’s my package.json

{
  "name": "example",
  "version": "1.0.0",
  "description": "",
  "main": "index.ts",
  "license": "MIT",
  "private": true,
  "scripts": {
    "start": "node ./dist/index.js",
    "dev": "nodemon ./src/index.ts",
  },
  "dependencies": {
    "@types/express": "^4.17.17",
    "express": "^4.18.2",
    "ts-node": "^10.9.1",
    "typescript": "^5.2.2"
  },
  "devDependencies": {
    "@types/node": "^20.6.0",
    "nodemon": "^3.0.1"
  }
}

why’s the error?

Use absoolute paths. I don’t know what tsc is but it is probably not found in the image during the build. Maybe because its location is not in the PATH variable or it doesn’t exist in the container.
