CS 151 - Day 20

Cay S. Horstmann

Lab

• Work with a buddy
• One of you codes, the other types up the answers.
• One of you submits the code in the lab20 subdirectory of your personal repo, the other submits a file report.txt in the lab20 subdirectory of your personal repo.
• Put the name of the coding buddy into the report

React Tutorial

• Follow the tutorial at https://reactjs.org/tutorial/tutorial.html
• Do the steps in Setup Option 2: Local Development Environment before coming to class. This will take a long time.
• Move the my_app directory inside the cs151 directory, renaming it to lab20:

  cd ..
  mv my_app ~/cs151/lab20
  cd ~/cs151/lab20
  

• When advised to run npm start, instead execute

  echo SKIP_PREFLIGHT_CHECK=true > .env
  npm start
  

• Work through as much of the tutorial as you can.
• Before checking in, put node_modules into your .gitignore!!!
• Be prepared to discuss at the end of class: What does React do for us?
