Example Storefront

Reaction Commerce is building a headless event-driven e-commerce ecosystem that empowers businesses to create a variety of dynamic shopping experiences. This Example Storefront is to serve as a reference on how to implement a web based storefront using the Reaction Commerce GraphQL API. You can fork this project as a jumping off point or create your own custom experience using your prefered client-side technology. While we feel our example storefront is full featured enough to use in production, it may be missing features your shop requires at this time.

Features

• Headless ecommerce example storefront built with Next.js, React, MobX, GraphQL, Apollo Client
• Reaction GraphQL API integration
• Server-side rendering
• Payments with Stripe
• Analytics with Segment or any other provider
• Reusable, customizable, themeable ecommerce React components from the new Reaction Component Library with Styled Components
• Fully-configured test suite: Jest snapshot testing, Mocha integration testing
• Written in ES6, configured with ES6
• Containerized with Docker

Getting Started

Follow the Reaction Platform docs to install and run all the services necessary to run the storefront:

Directory: Service	URL
reaction: GraphQL API	localhost:3000/graphql-beta
reaction: GraphQL API playground	localhost:3000/graphiql
reaction: Operator UI	localhost:3000
reaction: MongoDB	localhost:27017
reaction-hydra: Authentication	localhost:4444
example-storefront: Storefront	localhost:4000

Configuration

Set up Stripe

When running the storefront and Reaction for the first time, you will need to configure Stripe payment processing and shipping options to test a complete order checkout flow. After signing up for a Stripe API key, follow these steps:

1. Add public Stripe API key (STRIPE_PUBLIC_API_KEY) to .env.
2. Open the Reaction Classic app, at http://localhost:3000. Log in as an Admin user.
3. Open Payments: Enable Stripe by checking the box. Add a Stripe secret key and public key.
4. Open Shipping: Enable flat-rate shipping by checking the box. Enable at least one type of flat-rate shipping by clicking on the option in the table and checking the box.

Set up Analytics event tracking

Read the docs for setting up Segment or a custom analytics tracker

Documentation

• Example Storefront full documentation
• Reaction Component Library repository, documentation, and component documentation
• Reaction Docs: Using GraphQL
• Reaction Docs: Testing with Jest
• Reaction Docs: Developing with Docker

Development

The Reaction Platform runs the storefront with Docker, so you will have to use Docker commands to view logs, run commands inside the container and more. To run commands specifically for the storefront, make sure to change directories into the example-storefront directory within the reaction-platform repository:

cd example-storefront

Build and run in development mode with logs

docker-compose up -d && docker-compose logs -f

Run in development against a production API

Change the INTERNAL_GRAPHQL_URL in .env to the production API URL. The URL should end in /graphql-beta, like: https://my-website.com/graphql-beta. Save the .env file and restart the application with:

docker-compose run --rm --service-ports web yarn start

Run commands in container

docker-compose run --rm web [command]

Run any command inside a Docker container and then remove the container. Use this to run any tooling operations. Remember your project directory will be mounted and things will usually just work. See Yarn section below for more examples.

Run tests in container

Run tests locally

docker-compose run --rm web yarn test

Run tests locally without cache (this can be helpful if changes aren't showing up)

docker-compose run --rm web yarn test --no-cache

To update a failing snapshot (if you've made changes to a component)

docker-compose run --rm web yarn test -u

To run Snyk security tests (this will run tests in the same way as CI)

docker-compose run --rm web sh -c "cp package.json ../ && cp .snyk ../ && cd .. && snyk auth && snyk test"

To run ESLint

docker-compose run --rm web eslint src

Debugging the server with Chrome DevTools

You can use the Google Chrome DevTools to debug the code running in the Node.js application server while it's running inside Docker.

• run docker-compose run --rm --publish 9229:9229 --publish 4000:4000 -e NODE_ENV=development web node --inspect=0.0.0.0:9229 ./src/server.js
• Open Chrome and browse to chrome://inspect. Find the process under Remote Target and click inspect.

Yarn Commands

Yarn & NPM should run inside the Docker container. We've taken steps to ensure that the node_modules are placed into a cacheable location. If you run Yarn locally, the node_modules are written directly to the project directory and take precedence over those from the Docker build. Yarn Add

docker-compose run --rm web yarn add --dev [package]

Yarn Install

⚠️ Always rebuild the image and start a new container after modifying yarn.lock or Dockerfile!

docker-compose run --rm web yarn install
docker-compose down --rmi local
docker-compose up -d --build

Testing reaction-component-library components in the storefront

Sometimes we need to test reaction-component-library components in the context of the storefront. Unfortunately, there isn't an easy wasy to do this within our Docker containers, so we need to run the storefront outside of docker.

1. cd to your local reaction-component-library repo.
2. Git checkout the proper branch that you want to link
3. cd into the package folder of this repo, and run the command yarn install followed by yarn build
4. After the build is done, cd into the new dist folder it just built and run yarn link to allow the library to be installed into the storefront. This will link @reactioncommerce/components
5. Inside the example-storefront repo, temporarily rename your .yarnrc file to anything else (i.e. .yarnrc-temp)
6. Run yarn install and then the command yarn link "@reactioncommerce/components" to set the local version as an override of the published npm version
7. Inside your .env file, change INTERNAL_GRAPHQL_URL to equal http://localhost:3030/graphql-beta, the same as the EXTERNAL_GRAPHQL_URL
8. Start the storefront locally by running the command export $(cat .env | xargs) && yarn dev
9. Your storefront should now be running at localhost:4000
   • If you see errors about not being able to find peer dependency packages, that seems to be an issues with yarn linking. You can just temporarily yarn add each of those packages in the component library package/dist folder. (This folder is gitignored anyway.)
10. After your changes are tested, shut down the storefront by running the command CTRL+C
11. Run yarn unlink "@reactioncommerce/components" in the storefront repo folder
12. cd to the package/dist folder of the reaction-component-library repo. Run the command yarn unlink to unlink the local version of the component library
13. Undo the renaming of your .yarnrc file
14. Undo the URL change inside your .env file

Clean up containers

Stop, and retain containers:

docker-compose stop

Stop, and remove containers:

docker-compose down

Stop, and remove containers, volumes and built images:

docker-compose down -v --rmi local

Build and run the production app locally

Sometimes it is helpful during development to make a production build of the app and run that locally.

Run this command to build a Docker image with the production build of the app in it:

docker build -t reaction-storefront --build-arg BUILD_ENV=production .

Then, to start the app on your machine, make sure the Reaction API container is already running and enter:

docker run -d --name storefront -p 4000:4000 --env-file .env --network api.reaction.localhost reaction-storefront

NOTE: You can replace the number before the colon in 4000:4000 with a different localhost port you'd like the application to run at.

NOTE: This is not the way to run the app in actual production deployment. This is only for running the production build locally for development, demo or trial purposes.

To stop the Docker container after starting it with the above command, use:

docker stop reaction-storefront
