Countries

An app that displays country data using technology that I like or want to try.

Original data is from https://restcountries.com/v3.1/all, September 2023.

Disclaimer

This app isn't production ready:

• it only works on localhost
• security hasn't been considered (eg. cors is enabled for everyone)
• test coverage is low
• UX is almost completely absent in some places

Frontend

• cd frontend

Setup

• npm install
• Generate new component (eg button) with npx shadcn-ui@latest add button

Useful commands

• npm run dev
• npm test
• see also scripts in package.json

Backend

• cd backend

Setup

• cp .env.example .env
• npm install
• start db with docker-compose up -d
• npm run db:reset

Useful commands

• npm run start:dev
• npm test
• see also scripts in package.json
• interact with db docker exec --tty --interactive countries-postgres-dev psql --host=localhost --username=postgres --dbname=countries-dev

Architecture Decision Records

1. react-router-dom@6?
   • no. Documentation is overwhelming
   • use v5 instead
2. deno?
   • no. I don't know if it has enough traction to be worth learning yet.
3. backend framework
   • choice: nestjs
   • alternative 1: nextjs instead. No, because I thought it would be too much new at once
     • might be worth considering later
   • alternative 2: fastify. No, because its motivation is performance that that isn't a priority
4. trpc?
   • no. I think it's too new
   • might be worth considering if switching to nextjs
5. Where should the backend live?
6. deprecated: no need to store countries in a DB because because it's only a read operation
   • sorting/filtering/searching can be done in the FE
7. store countries in DB otherwise there are multiple data sources
8. use @lukemorales/query-key-factory?
   • no. I didn't understand the value
9. Should prisma be inside src?
   • no. It is isn't in this example
10. use zod for validation at runtime
