Build a Restful Api with Node.js Express & MongoDB | Rest Api Tutorial

We are going to cover how to create a restful api using node.js express and mongodb together with mongoose.

Rest apis help us decouple our backend code from our front end so we can use it across multiple application (mobile apps, web apps, etc).

We are going to learn how to build a simple blog post type api with all the useful methods(GET,POST,DELETE,PATCH).

We use Node.js as our backend language, express.js is going to help us create routes easier and middlewares and we use mongodb together with mongoose to create schemas and models that define how our data looks.

If you are a beginner with nodejs, express or mongodb I hope that this tutorial will give you a good idea of how these technologies work well together.

What is REST API? An Overview | Liquid Web

What is REST?

The REST acronym is defined as a “REpresentational State Transfer” and is designed to take advantage of existing HTTP protocols when used for Web APIs. It is very flexible in that it is not tied to resources or methods and has the ability to handle different calls and data formats. Because REST API is not constrained to an XML format like SOAP, it can return multiple other formats depending on what is needed. If a service adheres to this style, it is considered a “RESTful” application. REST allows components to access and manage functions within another application.

REST was initially defined in a dissertation by Roy Fielding’s twenty years ago. He proposed these standards as an alternative to SOAP (The Simple Object Access Protocol is a simple standard for accessing objects and exchanging structured messages within a distributed computing environment). REST (or RESTful) defines the general rules used to regulate the interactions between web apps utilizing the HTTP protocol for CRUD (create, retrieve, update, delete) operations.

What is an API?

An API (or Application Programming Interface) provides a method of interaction between two systems.

What is a RESTful API?

A RESTful API (or application program interface) uses HTTP requests to GET, PUT, POST, and DELETE data following the REST standards. This allows two pieces of software to communicate with each other. In essence, REST API is a set of remote calls using standard methods to return data in a specific format.

The systems that interact in this manner can be very different. Each app may use a unique programming language, operating system, database, etc. So, how do we create a system that can easily communicate and understand other apps?? This is where the Rest API is used as an interaction system.

When using a RESTful API, we should determine in advance what resources we want to expose to the outside world. Typically, the RESTful API service is implemented, keeping the following ideas in mind:

• Format: There should be no restrictions on the data exchange format
• Implementation: REST is based entirely on HTTP
• Service Definition: Because REST is very flexible, API can be modified to ensure the application understands the request/response format.
• The RESTful API focuses on resources and how efficiently you perform operations with it using HTTP.

The features of the REST API design style state:

• Each entity must have a unique identifier.
• Standard methods should be used to read and modify data.
• It should provide support for different types of resources.
• The interactions should be stateless.

For REST to fit this model, we must adhere to the following rules:

• Client-Server Architecture: The interface is separate from the server-side data repository. This affords flexibility and the development of components independently of each other.
• Detachment: The client connections are not stored on the server between requests.
• Cacheability: It must be explicitly stated whether the client can store responses.
• Multi-level: The API should work whether it interacts directly with a server or through an additional layer, like a load balancer.

An API-First Approach For Designing Restful APIs | Hacker Noon

I’ve been working with Restful APIs for some time now and one thing that I love to do is to talk about APIs.

So, today I will show you how to build an API using the API-First approach and Design First with OpenAPI Specification.

First thing first, if you don’t know what’s an API-First approach means, it would be nice you stop reading this and check the blog post that I wrote to the Farfetchs blog where I explain everything that you need to know to start an API using API-First.

Preparing the ground

Before you get your hands dirty, let’s prepare the ground and understand the use case that will be developed.

Tools

If you desire to reproduce the examples that will be shown here, you will need some of those items below.

• NodeJS
• OpenAPI Specification
• Text Editor (I’ll use VSCode)
• Command Line

Use Case

To keep easy to understand, let’s use the Todo List App, it is a very common concept beyond the software development community.
