Contracts

Solidty's code is encapsulated in contracts. A contract is the fundamental building block of Ethereum applications -- i.e. all variables and functions belong to a contract, and are the starting point of your project. Below is an example of an empty contract called HelloWorld.

Knex.js Joins

Adding Knex to the endpoints

Now that you have a good understanding of the Knex's capabilities, let's look at adding Knex to our Express app endpoints. Quit the nodemon drills.js process and start the server.

Open Postman and navigate to http://localhost:8080/restaurants. You should get back a list of restaurants. The SELECT statement is straight forward, the only thing to point out is the addition of in the `.then(results => res.json(results) );

Inner Join

Let's tackle the grade first.

OpenWeatherMap / Weather Icons integration

  1. Include Weather Icons in your app: https://github.com/erikflowers/weather-icons

  2. Include the below JSON in your application, for example purposes, lets assume it's a global named weatherIcons.

  3. Make a request to OpenWeatherMap:

req = $.getJSON('http://api.openweathermap.org/data/2.5/weather?q=London,uk&callback=?');
