JWT Generator: An Open-source JSON Web token(JWT) Generator For React

JWT generator

An open-source JSON Web Token (JWT) generator created by enabler 

JWT generator allows you to generate JWT in an easy way! 
We created a form with inputs, so you can easly pass in the data and create a signature using HS256 algorithm.

What is JSON Web Token?

JSON Web Token is a token-based standard that allows us to securely transfer information between two parties as a JSON object. The tokens are signed using cryptographic algorithm, either using a private secret (HMAC algorithm) or a public/private key (RSA).

JWT consists of three parts seperated by dots ( . ), which are:

So a JWT typically looks like:

xxxxx.yyyyy.zzzzz

Header

The header usually consists of two parts:

  • algorithm used for signing, ex. HS256
  • type of the token, which is JWT.


 


 

Then, this JSON is Base64Url encoded to form the first part of the JWT.


 

Payload

The payload contains the claims, which are statements about an entity (usually user) and additional data.


 


 

The payload is then Base64Url encoded to form the second part of the JWT.


 

Signature

The signature is created by signing the encoded header that is providing the algorithm, encoded payload with all the data and the secret (symmetric or asymetetric dependent on which algorithm is used).


 


 

The signature is used to ensure that the message was’t changed in the way. The party that creates the JWT signs the header and payload with a secret that is known to both the issuer and receiver, or with a private key known only to the sender. When the token is used, the receiving party verifies that the header and payload match the signature.


 


 

The output is three Base64 strings separated by dots that can be easily passed in HTML and HTTP environments, while being more compact compared to XML-based standards such as SAML.

When should we use JWT?

  • Authentication
  • Information Exchange

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Top 7 Open Source React Native Packages of 2020

React Native (RN) is a popular cross-platform framework with several built-in components that come ready to use in your project. Additionally, React Native comes with many open source libraries supported by its strong developer community. The community keeps these libraries up-to-date to ensure quick development and deployment of solutions.

React Native supports a greater number of libraries than Xamarin, Flutter, or Ionic, which makes it a framework of choice for clients and developers. In this article, we are going to talk about the top 7 libraries that are used in React Native projects.

1. NativeBase

NativeBase is one of the most popular libraries within the React Native community and has more than 43K weekly downloads, 14.2K GitHub stars, and 1.7K GitHub forks.

NativeBase is a dynamic frontend framework created by passionate developers from the React community. It enables developers to build high-quality mobile apps using React Native with support for the latest ECMAScript standards.

Some of the companies that leverage this library includes Microsoft, SocialDog, and Evand.

NativeBase specifically helps users design the look and feel of an app. Itfits well with mobile applications and cuts down a huge part of your effort during app development.

Installing NativeBase

npm install native-base --save

Sample Component Code snippet:

import React, { Component } from 'react';
import { Container, Button, Text } from 'native-base';
export default class Example extends Component {
  render() {
    return (
      <Container>
        <Button>
          <Text>
            Button
          </Text>
        </Button>
      </Container>
    );
  }
}

NativeBase components are created using the React Native platform along with some JavaScriptfunctionality and are highly customizable to fit most project needs. NativeBase also comes with starter kits that provide a wide range of templates for different business use cases. One of the main advantages of this library is that it integrates well with other third-party libraries. NativeBase provides the same look and feel as the operating platform on which it runs and allows users to easily customize components by creating a separate file.

NativeBaserenders the same UX as natively written applications because NativeBase uses the React Native platform’s default rendering and layout engine. It allows you to have a common codebase for your entire application’s code.

Spring Security with JSON Web Token and Refresh Token

In this tutorial, you will understand and learn how to generate and sign a JSON Web Token to securely access your RESTful application. This tutorial teaches how to use JWT (JSON Web Token) to embed user roles and permissions to delegate users authorization(what they can and can’t do) in the application. It also dives into defining and creating API, exposing API Endpoints over HTTP, and testing API Endpoints (using an HTTP client - Postman).
