Build a CRUD Rest API with Node & Express

Hello guys, in this video we will be building full crud application with the help of Node Express & React. So, initially we will be creating all CRUD rest api with Node & Express then we will integrate those api in our React Web Application.

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.

REST API In Laravel Example

Hello Friends,

Today I will give you information about REST API, REST API is an application program interface that uses HTTP requests to GET, PUT, POST and DELETE data.

In this tutorial I am going to perform CRUD operation using REST API and you can learn how to create REST API with authentication using passport in laravel 6/7 application. here we will get data from API.

Why You Should Consider Low-Code Approach to Building a REST API

APIs have been around for decades – they allow different systems to talk to each other in a seamless, fast fashion – yet it’s been during the past decade that this technology has become a significant force.

So then why all the interest in APIs? We all know the usual stories – Uber, Airbnb, Apple Pay… the list goes on, and the reasons are plentiful. Today the question is, how? Perhaps you are looking to differentiate your business or want a first-mover advantage.  How can you execute quickly and at low cost/risk to try new market offerings?

An API provides several benefits to an organisation, but without a dedicated team of trained developers, it might seem like an implausible option. Developers are expensive, and it can take months to develop an API from the ground up. If you don’t fancy outsourcing or have the capability in house to build internal APIs, a low-code platform might just be the answer.

Before You Begin: Plan long-term, start small.

For a small one-page application, this might only be a day or two of talking with stakeholders and designing business logic. The purpose of this first step is to ensure that the API will cover all use cases and provides stakeholders with what they need. Refactoring an entire coding design due to missing business logic is not only frustrating for the development team but adds high cost and time to the API project.

During the planning and design stage, remember that running an API requires more infrastructure than just resources to execute endpoint logic. You need a database to store the data, an email system to send messages, storage for files, and security to handle authorisation and authentication. These services can be farmed out to cloud providers to expedite the API build process (e.g. AWS provides all these infrastructure components, but Microsoft Azure is an optional cloud provider with SendGrid as the email application.)

**Planning considerations: **An API “speaks” in JSON or XML, so the output provided to client applications should be decided. Should you choose to later create endpoints for public developer consumption, you could offer both for ease-of-use and fostering more adoption. Ensuring the API follows OpenAPI standards will encourage more adoption and attract more developers.
