WarsawJS #62 — My experience with Node.js in Docker

This project template shows how to use Docker containers to encapsulate all development dependencies for a Node.js app.

Out of the box, you'll be able to use this template to develop a Next.js/React app and deploy it on ZEIT Now.

To start developing

  1. Install Docker CE.

  2. Copy .env.example file and rename it to .env. Open the .env file in your editor and provide values for all environment variables listed in the file.

  3. Open a terminal window, navigate to the project folder and type:

    ./up

    You will be dropped into the shell inside the Docker container.

  4. To start Next.js and other development tools, e.g., ESLint, type in the container shell prompt:

    yarn run watch

  5. In case you need additional container shells (running tests for example), type ./attach in another terminal window or tab on your host machine.

  6. When you're ready to deploy, type:

    yarn run deploy

Stopping containers

  1. To stop the project containers, open a terminal window on your host machine, navigate to the project folder and type:

    ./down

Notes

This project uses Yarn package manager by default. Please use Yarn CLI commands within the container to manage dependencies.

Amend the ./web/docker-environment.sh script if you would like to use npm or other package manager.

To improve performance in Docker for Mac and in Windows WSL, the node_modules folder in this project is symlinked to a folder inside a Docker volume. The node_modules folder contents are available within the container only.
