The Generated Service

Amplication auto-generates fully functional human-readable and editable services based on TypeScript and Node.js.

The generated services include NestJS, Prisma, REST API, GraphQL API, a React admin UI, authentication, authorization, logging, and more.

In this article you can find the details on the structure of a single service and the technologies behind it.


You can see an example of a service generated with Amplication in this repository


The generated service is built with the following proven open-source technologies:


  • NestJS - A progressive Node.js framework for building efficient, reliable and scalable server-side applications.
  • Prisma - Next-generation ORM for Node.js and TypeScript.
  • PostgreSQL - The World's Most Advanced Open Source Relational Database
  • Passport - Simple, unobtrusive authentication for Node.js
  • GraphQL - a query language for APIs.
  • Swagger UI - Visual documentation for REST API based on OpenAPI Specification.
  • Jest - delightful JavaScript Testing Framework with a focus on simplicity.
  • Docker - an open platform for developing, shipping, and running applications.


  • ReactJS - A JavaScript library for building user interfaces.
  • React-Admin - A unified admin framework using React, Material UI, React Router, Redux, and React-final-form.

Projects Structure

The generated service is built from two projects, each in a separate folder

  • Server - For all the server components including REST API, GraphQL, Services and more.
  • Admin - For the Admin UI including forms for CRUD operations on all data models.


The server project provides all the back-end services of your application, like REST API, GraphQL API, authentication, authorization, logging, data validation, and connection to the database.


The Admin project provide a React application with ready-made forms for creating and editing all the data models of your application. The React app is pre-configured to work with the server and comes with all the boilerplate and foundation for your client - routing and navigation, authentication, permissions, menu, breadcrumbs, error handling and much more.
