When attempting to build the awesome serialport NPM package in Docker using a node alpine image, in usually failes on building the node-gyp package.

There are various workarounds which can be found online, such as this one.

npm install serialport --build-from-source=serialport

Here's the full Dockerfile:

FROM node:12-alpine

WORKDIR /app/

COPY ./package*.json .

# copy the rest of your app

RUN apk add --no-cache --virtual .gyp \
            python \
            make \
            linux-headers \
            udev \
            g++ \
    && npm install serialport --build-from-source \
    && npm install --production \
    && apk del .gyp
