Goal for the day

We’ll start the day with a long list of animal endpoint handlers. By the end of the day, we should have all animal pages served with one endpoint (GET /:id).

• Starter code for today
• Today’s finished code

Topic 1: EJS quickie

We will discuss the EJS alternative to Pug. While Pug has some great features, it can be difficult to create page partials, so we will quickly walk through the example from yesterday using EJS.

• EJS home page
• EJS tag reference

Activity objectives

1. Choose an engine: Pug/EJS
2. Convert your Assignment 2 html files to view files.

By the end of this activity, you should have no static html files in your public directory. They should be moved to your views directory.

Mid-day Huddle

Topic 2: Model fixtures with require() and module.exports

We will discuss the model in deeper detail.

• Model-View-Controller
• Function scope example
• Requiring modules in Node.js: Everything you need to know

Activity objectives

Assignment 1 and 2 linked your Destinations to random websites. Try creating a destinations.js module that you can use to import your destinations model into your app.

Topic 3: Dynamic endpoint handlers with request.params

See:

• Express Tutorial Part 4: Routes and controllers
• Understanding the req Object in Express.js
• request.params

Activity objectives

1. Using today’s finished code, refactor the GET /:id endpoint so that it uses the animal title instead.
