Notes on Deploying React App

• npx create-react-app my-app
• cd my-app
• git init
• npm install gh-pages --save
• In package.json
  • "homepage" : url of deployed site
  • In scripts:
    • "predeploy": "npm run build",
    • "deploy": "gh-pages -d build"
• git add .
• git commit -m "Initial Commit"
• git branch -M main
• git remote add origin url of github project
• git push -u origin main
• npm run deploy

For Tailwind Setup

• npm install -D tailwindcss
• npx tailwindcss init
• In index.css
  • @tailwind base;
  • @tailwind components;
  • @tailwind utilities;
• In tailwind.config.js
  • content: ["./public/index.html", "./src/**/*.{js,jsx,ts,tsx}"],

For Dockerizing App

- first create .dockerignore and add node_modules in it to ignore it.

• create Dockerfile :

  • FROM node:latest to import node
  • then add WORKDIR /app
  • then COPY package*.json to let docker knows about your list of dependencies
  • then RUN npm install to install all dependencies
  • then COPY . . to copy rest of the files
  • then EXPOSE port to let docker know where to expose it inside container but has nothing to do with port forwading
  • then CMD ["npm","start"]

- Done with Dockerfile now create docker compose.yml file to run multi-container in single cmd

• specify version
• services
• web service name
• then build
• then container name
• images name
• ports
• develop
  • watch -(to sync code changes)
    • action : sync
    • path : .
    • target : /app
    • ignore : -(to ignore node_modules)
    • action : rebuild -(to rebuild if package.json changed)
    • path: package.json

Special Notes

• react runs on default port 3000 if we port forward like - '1313:1313' it will not work
• to overcome this issue i discovered two solution
  • either change default port of react with "start": " PORT=1313 react-scripts start" and then expose the same port and port forward the same
  • second is if not changing default port then port forward in this way - '1313:3000' and keep expose as 1313
• don't forget in - '1313:3000' 1313 is local port and 3000 is container port
