You might be familiar with a few other similar database systems, like MySQL, Microsoft SQL Server, or MariaDB, which compete with PostgreSQL. PostgreSQL, commonly referred to as Postgres, is a free, open source relational database management system. In fact, the E in MERN, MEVN, and MEAN stack stands for Express.Īlthough Express is minimalist, it is also very flexible, leading to the development of various Express middlewares that you can use to address almost any task or problem imaginable. Express is one of the most popular frameworks for Node.js.

Delete: Use the DELETE method to remove a resource from the systemĪccording to the official Express documentation, Express is a fast, un-opinionated, minimalist web framework for Node.js.

Update: Use the PUT method to update a resource.

Read: Use the GET method to read a resource, retrieving data without altering it.

Create: Use the HTTP POST method to create a resource in a REST environment.

Four of the most common HTTP methods in a REST environment are GET, POST, PUT, and DELETE, which are the methods by which a developer can create a CRUD system. RESTful APIs most commonly utilize HTTP requests.

This set of essential operations is commonly referred to as CRUD. It should be able to create, read, update, and delete resources. When building an API, you want your model to provide four basic functionalities. REST systems are stateless, scalable, cacheable, and have a uniform interface. Therefore, a RESTful API is an API that conforms to the REST architectural style and constraints.

An API is an interface that software programs use to communicate with each other. Representational State Transfer (REST) defines a set of standards for web services.

Let’s get started! What is a RESTful API? The complete code for the tutorial is available on this GitHub repo. Basic knowledge of working with the command line.Familiarity with the JavaScript syntax and fundamentals.To follow along with this tutorial, you‘ll need: Setting up CRUD functions in a REST API.Connecting to a Postgres database from Node.js.To do so, we’ll set up a route for each endpoint and a function for each query. Our goal is to allow CRUD operations, GET, POST, PUT, and DELETE, on the API, which will run the corresponding database commands.

You’ll also learn how to install PostgreSQL and work with it through the command-line interface. Our API will be able to handle the HTTP request methods that correspond to the PostgreSQL database from which the API gets its data. We’ll also walk through connecting an Express server with PostgreSQL using node-postgres. In this tutorial, we’ll learn how to create a CRUD RESTful API in a Node.js environment that runs on an Express server and uses a PostgreSQL database.

CRUD REST API with Node.js, Express, and PostgreSQLĮditor’s note: This post was updated on 06 June 2022 to reflect updates to the pgAdmin client.įor a modern web developer, knowing how to work with APIs to facilitate communication between software systems is paramount.
