npm-docker-build v1.1.0

npm-docker-build

To use docker cache more effectively, prevent package.json file changes to break docker layer cache, so that pick out dependencies from package.json before docker build executes and COPY the ONLY dependency statements as package.json file to run npm install command when building image.

FROM node AS build-stage
WORKDIR /app

COPY src .
COPY deps-dev.json ./package.json
RUN npm i
COPY package.json ./package.json
RUN npm run build

FROM node
WORKDIR /app

COPY --from=build-stage build/ .
COPY ./deps-prod.json ./package.json
RUN npm i

ENTRYPOINT ['npm', 'start']
