Description

The application is designed to help people share books with each other. All you need to do - register on a website using your Telegram Alias.

The motivation of the project

Features

• User can publish books which he\she has.
• User can borrow the book, if it is available or wait in a queue otherwise.
• User can search for an interesting book using filters.
• User can publish the book which he\she wants to find in the printed version.

Use cases

In the development process the following principles were followed as closely as possible

• SOLID

  • single responsibility
  • open–closed
  • Liskov substitution
  • interface segregation
  • dependency inversion

  Code Example:

    public class Book {
    @Id
    @SequenceGenerator(name = "IdSeq", sequenceName = "book_seq", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "IdSeq")
    Integer id;
    @Column(name = "title")
    String title;
    @Column(name = "author")
    String author;
    @Column(name = "genre")
    String genre;
    @Column(name = "owner")
    String owner; // заменить на юзера
    @Column(name = "description")
    String description;
    @Column(name = "image")
    String image;

    @ManyToOne//(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "user_id", nullable = false)
    @JsonIgnore
    private User user;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
}

• REST

  • Client–server architecture
  • Statelessness
  • Cacheability
  • Layered system
  • Code on demand
  • Uniform interface

  Code Example:

export default function BookInfo({book}){
   return(
       <div className="info">
           <div className="imgCover">
               {book.image ? (
                   <img className="bookImg" src={book.image}/>
               ) : (
                   <img className="bookImg" src="no_image.png"/>
               )}
           </div>
           <div className="bookInfo">
               <h1>{book.title}</h1>
               <h2>{book.author}</h2>
               <h3>Genre: {book.genre}</h3>
               <br/>
               <p>Book owner: {book.owner}</p>
               <p>{book.description}</p>
           </div>


       </div>
   )

Frameworks:

• Composite pattern

🔨 Architecture

The architecture of the project is based on Model-View-Controller architecture. We separated the business logic of the application (Model) and the visual part of the application (View). We choose MVC type of architecture for several reasons:

1. Separation on View and Model will increase the reusability of the code.
2. This separation makes it easier to expand and maintain the system in the future.
3. MVC simplifies the program writing and improves code readability
