![]() ![]() 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.The server allows the utilization of numerous methods to effectively establish the internal connection well. This tutorial covered all the steps required to install the required components of PostgreSQL using npm and to further utilize communication using commands. Well done! You should now be able to have a functional API that runs effectively on Node.js and uses a connected PostgreSQL database. A package.json is simply a file containing all the dependencies for your project: !`)) This creates a package.json in the directory in which this command is run. We can do that by simply running the following command in the terminal: npm init -y To get started, first we need to initialize our node project. Generally, it is really simple to get started with the installation of the required elements. The following software components are required before we can begin developing the API: ![]() First, we need to check that we have installed certain required software to ensure that the right environment is present for the development to take place. Getting started with development is simple. Why Use Node.js and PostgreSQL?Įven though there a range of different options available when it comes to creating an API, we are using Node.js and PostgreSQL for the sheer convenience they provide in the creation of APIs.Ĭontrary to other frameworks, we can get our API up and running in a matter of minutes thanks to the convenience afforded to us by our choice. The step-by-step instructions will help you gain a clear understanding of the process. We will explore all the required steps to set up the environment and go deeper into the actual creation of the API. We start from the basics and then delve into every step that you need to take to set up your API. Today’s tutorial digs deeper into the use of PostgreSQL to create a communicative API that works along with Node.js. The framework allows the creation of simple APIs that can be up and running in a matter of minutes. Unlike in the past, streamlined communication is now easy to have thanks to Node.js. It is critical for software systems to have a seamless communication system to mutually communicate all the important details. This article describes how you can use Node.js and PostgreSQL to create an API and provides an example for how to create a table. ![]()
