Architecture Overview

Hacker News Clone Architecture Overview

server.ts is the entry point. It uses Express and passes requests to Next. Next SSR renders the pages using getServerSideProps() hook from Apollo helper. Therefore the app makes GraphQL requests on the client or server.

When the client loads the page it preloads next pages code from any <Link href="/">. When the client navigates to the next page it only needs to make one GraphQL query to render. Great!

GraphQL: GraphQL-Tools by Apollo or GraphQL docs

Directory Structure

Each web page has a React component in pages. Server code is in server. Shared code that runs on client or server is in src. Do not import from server or pages in src to avoid running code in the wrong environment.

The project root contains config files such as TypeScript, Babel, ESLint, Docker, Flow, NPM, Yarn, Git.

How To Start

One Click Download & Run

You can download and run the repo with one command to rule them all:

git clone https://github.com/clintonwoo/hackernews-react-graphql.git && cd hackernews-react-graphql && npm install && npm start

Setup

Running the app in dev mode is fully featured including hot module reloading:

npm install

npm start

To run in production mode:

npm run build:prod && npm run start:prod

Configuration

The project runs out of the box with default settings (/src/config.ts). You can include a .env file in your project root to configure settings (this is the 'dotenv' npm package). The .env file is included in .gitignore.

How To Test

Jest

npm test

This project uses Jest and can do snapshot testing of React components. Whenever a component is changed, please update the snapshots using npm test -- -u or npx jest --updateSnapshot.

How To Build For Deployment

npm run build:prod: NextJS app with entry point server.ts that uses Node.js/Express. Uses TypeScript compiler to transpile project src to build.

OR

npm run build-docker Docker Container: Builds a docker container using Dockerfile.

Static Website (Optional)

NextJS lets us make a powerful static website but you need to consider if you need server side rendering.

npm run build-static-website: Builds static website to /build/static. Use a static web server eg. NGINX/Github Pages.
