Agenda

  1. Recap javascript3
    • callbacks and promises
  2. What is backend and why is it needed?
  3. Web servers - with emphasis on Node.js (mention that there are other technologies but don't go into details such as threads vs async)
  4. Node.js hands on, basic example
    • how to run a script
    • where to find documentation
  5. Client-server model (introduce URL endpoints and ports)
    • introduce HTTP. students need to know about request and response and content types, leave methods and status codes and body for week2
  6. NPM - explain require with a local file (see code-width-students). Then npm init. Finally explain npm install (don't go into details of dependencies vs devDependencies and global vs local, its too much)
  7. Express.js (again mention that there are other modules notably http but don't go into specifics)
  8. Briefly explain homework assignment
