A game-type project developed as an academic endeavour during our studies on WUST (PL).

Table of Contents:

• 1. Model
• 2. Client application program
• 3. Server application program
  • 3.1. Database
  • 3.2. Auxiliary classes
  • 3.3. Error Handling

All model classes and interfaces are defined in the model directory.
For example all errors that can occur are defined as an enum in model/errors.ts.

The source files are in the client directory.

The front-end application is an Angular application built using @angular/cli.

Before running the program, you need to have the Angular CLI program installed globally in your system (use npm install -g @angular/cli). For some reason Angular CLI installed locally can’t be run.

To run the program in development mode use

npm run dev

whilst being in the client directory.

The source files are in the server directory.

The back-end application is an Express.js (with TypeScript) application.

To run the program in development mode use

npm run dev

whilst being in the server directory.

To initialize the database with empty schemas run

./init.sh

whilst being inside the server/database directory.

The application is using a few wrapper classes (located in server/src/auxiliary) that ensure type safety across the whole program.

Instead of using the standard Express.Router class for setting up routes here we use RouterWrapper that is the type-safe medium between our program and the Express Router API.

The program uses Promise-based errors which means when an Error is thrown Express will catch it. The error handler is defined in server/src/index.ts while all error types are defined in model/errors.ts as told in «Model».
