minimal-package-json

A small package to minimize package.json content

Why

Sometimes we need a package.json with minimal size and keep its content identical as long as possible.

Take Dockerfile as an example, to build a fresh docker image, we may create a bundle like:

mkdir dist
cp index.js package.json package-lock.json dist

With a Dockerfile installing dependencies in docker:

FROM node:alpine
ENV NODE_ENV production
COPY dist /app
WORKDIR /app
RUN npm install --production
CMD npm start
EXPOSE 8080

With a shell command to build this image:

docker build -t some-image-name -f Dockerfile dist

This possibly cause a long npm install on each docker build when some unrelated properties in package.json are changed.
