say hi to react through docker integration

10 Nov 2018

I’ve started learning react and there is no way I install npm/yarn/create-react-app or any non sense just to develop single pages.

Therefore here are some instructions to encapsulate everything within docker containers.


Being react the complex stack of software it’s, it requires create-react* scripts to bootstrap projects. Therefore the first step will be to create a minimal container with such tools:


FROM node:alpine
RUN yarn global add create-react-app create-react-native-app react-native-cli

Let’s call this container bootstrap-react:

$ docker build . -t bootstrap-react

Then we can bootstrap react/react-native projects as usual:

$ docker run -it --rm --user "$(id -u):$(id -g)" \
      -v "${PWD}":/usr/src/app -w /usr/src/app   \
      bootstrap-react                            \
      create-react-app my-new-react-project

The my-new-react-project folder contains a bunch of files required to start hacking away:

$ tree my-new-react-project/ | head
├── .gitignore
├── node_modules
│   ├── abab
│   │   ├──
├── package.json
├── public
│   ├── index.html
├── src
    ├── App.css
    ├── App.js

Dockerizing new project

Now, wouldn’t be cool if every person could replicate the project with a single step?, let’s add some more magic.


version: '3.4'

    image: node:alpine
      - .:/usr/src/app
    working_dir: /usr/src/app
    command: sh -c "yarn && yarn start"
      - "3000:3000"

That’s it!, now it can be launched and accessed through http://localhost:3000:

$ docker-compose up
app_1  | You can now view my-new-react-project in the browser.
app_1  | 
app_1  |   Local:            http://localhost:3000/
app_1  |   On Your Network:

Sweet!, the autoreloading is working, so we can start modifying files and the changes will show up instantly.

$ vim src/App.js
#some changes later ...

If you enjoyed the process but still don’t want to go thought all the steps, feel free to grab the docker-react-hello-world template as your starting point.

That’s it, happy coding, 😊
