The type property is used to specify the return type. You added the for GET, PATCH and DELETE endpoints and for POST endpoints. Add the following imports to ArticlesModule: To access PrismaClient inside the Articles module, you must add the PrismaModule as an import. The SwaggerModule searches for all and decorators on the route handlers to generate this API page. If you open the Swagger API page again, you should see something like this: Currently, this file contains dummy implementations. The business logic for handling each request is encapsulated in the src/articles/ file. Inside the src/articles/ file, you will see the definition of different routes (also called route handlers). You should now find a new src/articles directory with all the boilerplate for your REST endpoints. Would you like to generate CRUD entry points? Yes.What transport layer do you use? REST API.What name would you like to use for this resource (plural, e.g., "users")? articles.To generate and execute your first migration, run the following command in the terminal: With the Prisma schema defined, you will run migrations to create the actual tables in the database. The attribute will automatically update the field with the current timestamp whenever an article is modified.date the field with the current timestamp any time an article is modified. The two DateTime fields, createdAt and updatedAt, will track when an article is created and when it was last updated. The attribute indicates that this field should be set to false by default. The published field is a flag to indicate whether an article is published or in draft mode. The attribute indicates that this field should be automatically incremented and assigned to any newly created record. The id field has a special attribute called This attribute indicates that this field is the primary key of the model. Fields can be made optional by adding a ? after the field type. Each field has a name ( id, title, etc.), a type ( Int, String, etc.), and other optional attributes ( etc.). Here, you have created an Article model with several fields. Inside the prisma/prisma.schema file, add a new model to your schema named Article: For this tutorial, you will only need an Article model to represent each article on the blog. Now it's time to define the data models for your application. Note: For more information on Prisma schema, check out the Prisma docs. Right now there are no models in your schema, you will explore this part in the next section. Each model will be mapped to a table in the underlying database. Data model: Defines your database models.It is used to send queries to your database. Generator: Indicates that you want to generate Prisma Client, a type-safe query builder for your database.The above configuration means that your database provider is PostgreSQL and the database connection string is available in the DATABASE_URL environment variable. Data source: Specifies your database connection.The schema.prisma file has three main components: This file is written in the Prisma Schema Language, which is a language that Prisma uses to define your database schema. To start, run the following command in the location where you want the project to reside: You can use the NestJS CLI to create an empty project. It comes with built-in utilities that help you initialize, develop and maintain your NestJS application. The NestJS CLI comes in very handy when working with a NestJS project. The first thing you will need is to install the NestJS CLI. Note 2: If you don't have a Unix shell (for example, you are on a Windows machine), you can still follow along, but the shell commands may need to be modified for your machine. Note 1: The optional Prisma VSCode extension adds some really nice IntelliSense and syntax highlighting for Prisma. have access to a Unix shell (like the terminal/shell in Linux and macOS) to run the commands provided in this series. have the Prisma VSCode Extension installed. To follow along with this tutorial, you will be expected to: Note: If you're not familiar with NestJS, you can quickly learn the basics by following the overview section in the NestJS docs. Basic knowledge of JavaScript or TypeScript (preferred).Prisma as the Object-Relational Mapper (ORM).You will be using the following tools to build this application: Finally, you will build the REST API and document it with Swagger. Then you will start your own PostgreSQL server and connect to it using Prisma. You will get started by creating a new NestJS project. In this tutorial, you will learn how to build the backend REST API for a blog application called "Median" (a simple Medium clone). Add PrismaClient to the Articles module.Implement CRUD operations for Article model.
