Connect to Server

• follow steps in "Hello, Server!":
  • Connect to Server Using SSH
  • Initial Project Installation
  • Atom Text Editor

Edit file on server

• open this file on server: frontend/src/pages/Practical01.js
  • For those not using Atom editor file is located on server here: /home/USERNAME/code/cviceni/frontend/src/pages/Practical01.js
• content of Practical01.js should be this:

• replace Hello! with Counter: {0}
• save the file
• result should be visible at: http://dev.frontend.USERNAME.vse.handson.pro/practical/01

Create Simple React Counter

Open Practical01.js and implement simple counter.

Here is an example implementation

Acceptation criteria are:

• initial value of counter should be 0
• current value should be visible, eg: Counter: 0
• there should be +1 button
• if user presses the +1 button it should increment the counter by 1
  • user should see new value, eg: Counter: 1
  • user should be able to increment value multiple times
• don't use ugly hacks!

Hints

• you have to use useState hook
  • you have to import useState
  • replace this:
    with this:
• you can get some inspiration in Hello, React!
• or you can read more in React useState docs

Send a Link to Working React Counter

Once you are finished:

• send a link to working React counter
  http://dev.frontend.USERNAME.vse.handson.pro/practical/01
• using MS Teams to: Tomas Horacek (@hort19)
