    1. Installation

    npm install cds2types

    OR

    yarn add cds2types

    2. Usage

    Let's look at a CDS example:

    // schema.cds
    
    using { Currency, managed, sap } from '@sap/cds/common';
    namespace sap.capire.bookshop;
    
    entity Books : managed {
        key ID   : Integer;
        title    : localized String(111);
        descr    : localized String(1111);
        author   : Association to Authors;
        genre    : Association to Genres;
        stock    : Integer;
        price    : Decimal(9,2);
        currency : Currency;
    }
    
    type Gender : Integer enum {
        NonBinary;
        Male;
        Female;
    }
    
    type NameStr : String(111);
    
    type Name {
        firstname: NameStr;
        lastname: NameStr;
    }
    
    type Address {
        street: String;
        houseNo: String;
        town: String;
        country: String;
    }
    
    type Addresses : many Address;
    
    entity Authors : managed {
        key ID       : Integer;
        name         : Name;
        gender       : Gender;
        addresses    : Addresses;
        dateOfBirth  : Date;
        dateOfDeath  : Date;
        placeOfBirth : String;
        placeOfDeath : String;
        books        : Association to many Books on books.author = $self;
    }
    
    /** Hierarchically organized Code List for Genres */
    entity Genres : sap.common.CodeList {
        key ID   : Integer;
        parent   : Association to Genres;
        children : Composition of many Genres on children.parent = $self;
    }

    Now when we run the CLI:

    cds2types --cds ./service.cds --output ./service.ts --prefix I

    We get the following output:

    // service.ts
    
    export namespace sap.capire.bookshop {
        export type Addresses = IAddress[];
        export type NameStr = string;

        }
    
        export interface IAddress {
            street: string;
            houseNo: string;
            town: string;
            country: string;
        }
