Product Catalog Application

A template nodejs application using Nuxt for a component and page rendering server. Nuxt application components load data (when rendering on the server or client) from a GraphQL search endpoint, that retrieves data from an elasticsearch endpoint.

Dependencies

Requires Docker and Docker Compose to be installed on the host machine.

Building All Dependencies

The docker-compose command with pull down all necessary images for Node.js, Elasticsearch, and Nginx, and build the GraphQL and Nuxt server applications (npm run build as defined in each applications Dockerfile).

Install Docker Compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Raise Default memory limit on host machine as required by the elasticsearch container. More Details.

Resolves Issue: Invalid kernel settings. Elasticsearch requires at least: vm.max_map_count = 262144.

sudo sysctl -w vm.max_map_count=262144

Build the App and All Dependencies

# Build dev dependencies
docker-compose -f docker-compose-dev.yml build

# Build prod dependencies
docker-compose build

# Using docker-compose >= 1.23.0
docker-compose build --parallel

---

Running the App

# Dev
docker-compose -f docker-compose-dev.yml up -d

# Prod
docker-compose up -d

The app should now be available on localhost port 80: http://localhost.
