Mastering TypeScript - Slice-it Pizza Sample Application

Slice-it Pizza is a simple food order management system.

It allows the user to input food items and orders containing specific food items.

Recommended Text Editor

This code is designed to be used with Visual Studio Code. It's free and runs on Windows, OS X, and Linux.

Individually open up the web-app folder and server-app folder.

Setup

Download and install Node.js 4.1+.

In the server-app run:

~/server-app> npm install
~/server-app> gulp
~/server-app> npm start

Then in the web-app run:

~/web-app> npm install
~/web-app> gulp
~/web-app> npm start

• npm install - Installs the application dependencies
• gulp - Builds the application
• npm start - Starts the application

Make sure to start the server-app before running the web-app. Otherwise the web-app will have nothing to connect to.

server-app

Listens for requests to list/insert/update/remove food items and orders from a database.

See ~/server-app/readme.md for more details.

web-app

Interacts with the server-app to list/insert/update/remove food items and orders.

The user is displayed information and they can view/add/update/remove food items and orders.

See ~/web-app/readme.md for more details.

Section 8, Video 3 - Code Generation

More information in Section 8, Video 3 on Code Generation.

Code is generated from the FoodItemRoutes and OrderRoutes classes in the server-app to the ServerFoodItems and ServerOrders classes in the web-app, respectively. Other related files are also copied to the web-app from the server-app.

• Code generation: ~/server-app/src/routes/food-item-routes.ts -> ~/web-app/src/scripts/server/server.ts as ServerFoodItems
• Code generation: ~/server-app/src/routes/order-routes.ts -> ~/web-app/src/scripts/server/server.ts as ServerOrders
• Copied files: ~/server-app/src/models/* -> ~/web-app/src/scripts/server/*

Code generation and copying happens when running the gulp copy-server-files or just gulp command is run in the ~/server-app folder. It does this by using an experimental library called server-bridge, which gets type information from the code by using another experimental library called ts-type-info then writes some code the web-app can use to easily interact with the server.
