I'm currently working on a few micro-services with Docker. The architecture looks promising to me, and I like to play with Docker containers. Lately I've been watching a few videos about Node.js/GraphQL Microservices by Better Coding Academy. The tutorial series assumes a lot of knowledge (JavaScript, Express, GraphQL, Docker). I would have liked more detailed explanations. But the videos are still useful for showing the architecture of an Express/GraphQL setup with micro-services.

Today I've tried to update one of my Docker apps that uses React, Enzyme, and Jest. This lead me on a wild goose chase about react-test-renderer and best practices for Docker builds for Node.js. I'm still not sure where the problem is (Enzyme, maybe?). But I found three useful resources for Docker and Node.js: Docker and Node.js Best Practices Node + Docker Hello World, for Showing Good Defaults for Using Node.

A few days ago, I switched to fnm as my version manager for Node.js. Before, I installed the default nodejs package that came with Arch Linux. But sometimes I would update my operating system, and thus getting a new Node.js version, and my system would break. With fnm, I have fine-grained control over which version of Node.js I'm running. Now, let's talk about package managers. Node.js ships with npm as the default package manager.

fnm offers a speedy alternative to the Node.js manager NVM. Built with native ReasonML, it's significantly faster than NVM. fnm Setup Here's how I set it up on an Arch-based Linux system that uses the Fish shell as an interactive shell. Use the installation script from fnm: $ curl -fsSL https://github.com/Schniz/fnm/raw/master/.ci/install.sh | bash The command downloads fnm, installs it and adds a loader to bash. The installation script above adds the following lines to .

I have the following Dockerfile for a React app:

base image FROM node:11.12.0-alpine # set working directory WORKDIR /usr/src/app # add /usr/src/app/node_modules/.bin to $PATH ENV PATH /usr/src/app/node_modules/.bin:$PATH # install and cache app dependencies COPY package.json /usr/src/app/package.json COPY package-lock.json /usr/src/app/package-lock.json RUN npm install react-scripts@3.0.1 -g –silent RUN chown -R node:node . USER node RUN npm ci # start app CMD ["npm", "start"] After setting up the work directory I copy the package.
