Getting Started

Goal

This snapshot advances Cobblecart Market by teaching you to boot Rails with Hotwire/Turbo on port 3010.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use Ruby 3.2+, Bundler, Node.js 20+, and Docker for Postgres stages.

Port 3010 must be free. Copy .env.example before database stages.

• Ruby and Bundler
• Node.js and npm
• Docker from part 4 onward

Concepts

Rails boots an HTTP server; Hotwire/Turbo drives interactive storefront UI; Tailwind styles the chrome.

Turbo keeps interactive UI on the server; Tailwind styles the storefront; Active Record owns persistence and authorization checks.

Walkthrough

Confirm the health endpoint and storefront home load together.

Read the example, then open the matching snapshot. The repository includes validation, CSRF, and the surrounding structure.

get "/health", to: proc { [200, {}, ['{"ok":true,"store":"Cobblecart Market"}']] }

Run and verify

Enter 01-Getting-Started, bundle install, copy .env.example, migrate, seed, and boot Puma on port 3010.

Open http://127.0.0.1:3010. From data lessons onward, Ada and Grace use password123.

git clone https://github.com/michaeldunga1/fcc-rails-ecommerce.git
cd fcc-rails-ecommerce/01-Getting-Started
bundle install
npm install
cp .env.example .env
bin/rails db:prepare
bin/rails server -b 0.0.0.0 -p 3010

Troubleshooting

If the browser cannot connect, confirm the process is still listening on 3010.

For database failures, confirm Docker and the cobble_NN name. Never commit .env, vendor/bundle, or node_modules.

• Read the first exception first
• Rebuild assets after Tailwind class changes
• Never commit secrets

Try this

Change the store name in config and confirm it appears on the home page.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
