common classes for TypeScript


To install @tsclass/tsclass, run the following command in your project directory:

npm install @tsclass/tsclass

This will add @tsclass/tsclass to your project's dependencies.


@tsclass/tsclass offers a comprehensive TypeScript library that provides common classes and interfaces for various domains, including business, finance, content, networking, and more. The package utilizes ESM syntax and is intended for use with TypeScript for optimal developer experience.

Getting Started

First, ensure that you are using ES Modules in your TypeScript project by having "type": "module" in your package.json, and install the package as described above.

Importing Classes and Interfaces

You can import classes and interfaces from @tsclass/tsclass as follows:

import { business, finance, content } from '@tsclass/tsclass';

Business Domain

The business domain includes classes for managing contacts, companies, and projects. Here is how you can work with a company and contact classes:

import { business } from '@tsclass/tsclass';

const companyContact: business.IContact = {
  type: 'company',
  name: 'Example Company',
  address: {
    streetName: 'Main St',
    houseNumber: '123',
    postalCode: '12345',
    city: 'Example City',
    country: 'Exland'
  description: 'An example company for demonstration purposes.',
  email: 'contact@example.com'

const exampleCompany: business.ICompany = {
  name: 'Example Company',
  foundedDate: {
    day: 1,
    month: 1,
    year: 2020
  status: 'active',
  contact: companyContact

Finance Domain

The finance domain provides interfaces for working with invoices, transactions, and payment information. Heres how you can define an invoice:

import { finance } from '@tsclass/tsclass';

const exampleInvoice: finance.IInvoice = {
  id: 'INV12345',
  billedBy: companyContact,
  billedTo: companyContact, // In a real scenario, this should be a different contact.
  status: 'draft',
  items: [
      name: 'Product 1',
      unitType: 'Item',
      unitQuantity: 2,
      unitNetPrice: 50,
      vatPercentage: 20,
      currency: 'EUR'
  dueInDays: 30,
  reverseCharge: false

Network Domain

Networking interfaces, such as those for managing SSH keys or network nodes, are available under the network namespace:

import { network } from '@tsclass/tsclass';

const sshKey: network.ISshKey = {
  keyName: 'example-ssh-key',
  public: 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD...'
  // Private key is typically kept secret and not included in source code

Storage Domain

Interfaces for storage management, such as S3 descriptors, can be found under the storage namespace:

import { storage } from '@tsclass/tsclass';

const s3Descriptor: storage.IS3Descriptor = {
  endpoint: 's3.example.com',
  accessSecret: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY',
  useSsl: true

Content and More

@tsclass/tsclass also provides classes for the content domain (e.g., articles, authors) and many other utilities across different fields. The examples above only scratch the surface of what @tsclass/tsclass offers. Depending on your project's needs, explore other domains and interfaces provided by the library.

Remember, while @tsclass/tsclass aims to streamline the TypeScript development process by providing ready-to-use classes and interfaces, it is crucial to adapt these examples to your specific project requirements, ensuring that all aspects, such as security (especially for networking and storage operations), are adequately handled.

For a deeper look into all available classes and interfaces, refer to the TypeScript definitions in the package. This will also give you insight into additional functionalities such as content management, events, authentication, and more detailed use cases within each domain.
