Ontime

It was a pleasure working with the TRT team. Prior to contracting this group, I had a system created that was absolutely terrible and poorly developed. I also worked with a few freelancers that couldnt cut it either. TRT was actually able to execute on our concept and have built a truly solid system for our company.

Microsoft Login Integration with React

This tutorial teaches you how to build a React single-page app that uses the Microsoft Login and retrieve user information using MSAL.js and Microsoft Graph API for a logged in user. What is MSAL.js? > MSAL for JavaScript enables client-side JavaScript web applications, running in a web browser, to authenticate users using Azure AD work and school accounts (AAD), Microsoft personal accounts (MSA) and social identity providers like Facebook, Google, LinkedIn, Microsoft accounts, etc. through Azure AD B2C service. It also enables your app to get tokens to access Microsoft Cloud services such as Microsoft Graph. Prerequisites * You should have either a personal Microsoft account or a Microsoft work or school account. * Setup the Microsoft Azure B2C tenant [https://docs.microsoft.com/en-us/graph/tutorials/react?tutorial-step=2] * Setup the initial react app project locally. (create-react-app) Install the required client-side libraries * react-router-dom [https://www.npmjs.com/package/react-router-dom] for declarative routing inside the React app. * bootstrap [https://www.npmjs.com/package/bootstrap] for styling and common components. * reactstrap [https://www.npmjs.com/package/reactstrap] for React components based on Bootstrap. * fontawesome-free [https://www.npmjs.com/package/@fortawesome/fontawesome-free] for icons. * msal for authenticating to Azure Active Directory and retrieving access tokens. * microsoft-graph-client for making calls to Microsoft Graph. Add Azure AD authentication 1. Create a new file in the ./src directory named Config.js and add the following code. Replace YOUR_CLIENT_ID_HERE with the application ID from the Application Registration Portal. Config.jsImplement sign-in In this section you'll create an authentication provider and implement sign-in and sign-out. * Initialize the authentication context by instantiating a UserAgentApplication with a configuration object. The minimum required configuration property is the clientID of your application, shown as the Application (client) ID on the Overview page of the app registration in the Azure portal. AuthProvider * Now, we can integarte login flow. Your app must login the user with either the loginPopup or the loginRedirect method to establish user context. Here, I am explaining with loginPopup method. Login Popup MethodGet an access token to call an API * In MSAL, you can get access tokens for the APIs your app needs to call using the acquireTokenSilent method which makes a silent request (without prompting the user with UI) to Azure AD to obtain an access token. The Azure AD service then returns an access token containing the user consented scopes to allow your app to securely call the API. * If you are using an interactive token call, it must match the login method used in your application. (loginPopup=> acquireTokenPopup, loginRedirect => acquireTokenRedirect) Get Access Token Using acquireTokenSilent method * If the acquireTokenSilent call fails with an error of type InteractionRequiredAuthError you will need to initiate an interactive request. This could happen for many reasons including scopes that have been revoked, expired tokens, or password changes. Interaction Required Auth ErrorSave your changes and refresh the browser. Click the sign-in button and you should see a pop-up window that loads https://login.microsoftonline.com. Login with your Microsoft account and consent to the requested permissions. The app page should refresh, showing the token. Get user details > In this section you will get the user's details from Microsoft Graph. * Create a new file in the ./src directory called GraphService.js and add the following code. Get User Details using Microsoft Graph API * This implements the getUserDetails function, which uses the Microsoft Graph SDK to call the /me endpoint and return the result. * Click the user avatar in the top right corner to access the Sign Out link. Clicking Sign Out resets the session and returns you to the home page. Go and change the MSAL Configuration if you want to manipulate the authentication settings for MSAL.JS. You can find the configuration options of MSAL.JS under this link [https://docs.microsoft.com/en-us/azure/active-directory/develop/msal-js-initializing-client-applications] . Storing and refreshing tokens However, this token is short-lived. The token expires an hour after it is issued. This is where the refresh token becomes useful. The refresh token allows the app to request a new access token without requiring the user to sign in again. Because the app is using the MSAL library, you do not have to implement any token storage or refresh logic. The UserAgentApplication caches the token in the browser session. The acquireTokenSilent method first checks the cached token, and if it is not expired, it returns it. If it is expired, it uses the cached refresh token to obtain a new one. Summarizing With this GitHub project [https://github.com/Pankti2612/react-msal] I am showing you how to authenticate against Azure AD using React. I will improve the current code and provide more samples on that repository. Also Please provide any feedback on this tutorial in the GitHub repository [https://github.com/Pankti2612/react-msal]. Happy coding.

How react hooks work?

React Hooks are introduced in version 16.8 released in February 2019. Hooks are API's or in-built functions introduced to use state and other features in React without writing a class. If you want to get started with React or React Hooks, here is official React documentation [https://reactjs.org/docs/getting-started.html]. In official documentation it only explains usage for react hooks, so we will learn about the working of hooks. Prerequisites * Should know JavaScript and React Before understanding the working of hooks let's take a quick look at the types of hooks react provide. Basic React Hooks 10 in-built hooks were shipped with React 16.8 but the basic (commonly used) hooks include: Basic Hooks [https://reactjs.org/docs/hooks-reference.html#basic-hooks] * useState [https://reactjs.org/docs/hooks-reference.html#usestate] * useEffect [https://reactjs.org/docs/hooks-reference.html#useeffect] * useContext [https://reactjs.org/docs/hooks-reference.html#usecontext] Additional Hooks [https://reactjs.org/docs/hooks-reference.html#additional-hooks] * useReducer [https://reactjs.org/docs/hooks-reference.html#usereducer] * useCallback [https://reactjs.org/docs/hooks-reference.html#usecallback] * useMemo [https://reactjs.org/docs/hooks-reference.html#usememo] * useRef [https://reactjs.org/docs/hooks-reference.html#useref] * useImperativeHandle [https://reactjs.org/docs/hooks-reference.html#useimperativehandle] * useLayoutEffect [https://reactjs.org/docs/hooks-reference.html#uselayouteffect] * useDebugValue [https://reactjs.org/docs/hooks-reference.html#usedebugvalue] Now let us understand how hooks work under the hood with the help of an example. const Counter = () => { const [counter, setCounter] = useState(0); onClick = () => setCounter(prev => prev + 1); return ( <button onClick={onClick}>Click me</button> <p>{[counter}}</p> ) } We have created a function with the name "Counter" which returns the button and counter value in view. > const [counter, setCounter] = useState(); Here we are using the useState hook which returns a current state value and a function to update current state value. Below is an example of the implementation of the useState hook function. let context = {}; // we will use this callId to persist the state for useState call let callId = -1; function render(Component) { // store the Component function to the context context.Component = Component; // invoke the Component function const instance = Component(); // render the Component instance.render(); // reset the callId after every render callId = -1; // add the instance to the context and retrun the context // so that we can invoke the other method of the instance // like so: // const context = render(Component); // context.instance.someInstanceMethod(); context.instance = instance; return context; } function useState(initialState) { if (!context) { throw new Error('hooks can not be called with out a rendering context'); } if (!context.hooks) { context.hooks = []; } callId = callId + 1; const hooks = context.hooks; const currentState = hooks[callId] ? hooks[callId] : initialState; hooks[callId] = currentState; const setState = function () { const currentCallId = callId; return function (newState) { hooks[currentCallId] = newState; render(context.Component); } }(); return [currentState, setState]; } Sample useState functionNote: This is not an exact implementation of useState that is in the original React code. In the above sample, we have a global context in which we have a component instance in context so we can access components in useState function, as we are calling useState directly from our custom components. In react for a component, it is compulsory to return something, mostly view. So in this functional approach, we do not have a render method but we return view. After compiling this function, react makes components from this function and puts this view in the render function. When the initial render is called with component instance, it is saved in context. Whenever the setState function is called, it updates the current value and calls the render function with the context component. This is how the render method is called on every state update and we get updated value in view. For more detailed explanations refer to this blog [https://medium.com/swlh/how-does-react-hooks-re-renders-a-function-component-cc9b531ae7f0] . > onClick = () => setCounter(prev => prev + 1); In this onClick function, we have triggered the setCounter function to update the counter value. return ( <button onClick={onClick}>Click me</button> <p>{[counter}}</p> ) When we click on the button it triggers the setCounter function which will update the counter value and in return, it triggers the render method and update value in view. Graphical representationIn the above explanation, we learn about the useState hook only, using a similar approach we can understand other hooks also, but there might be other things also to consider and understand like closure to properly understand its working.

Top 14 React Libraries You Must Try in 2020

Application development is all about choosing the right tools and frameworks that help you save development time and costs. When it comes to web app development, you must first understand how to choose the right technology stack for your application [https://www.thirdrocktechkno.com/blog/how-to-choose-a-technology-stack-for-web-application-development/] . Taking this decision requires you to have knowledge of how major frameworks like Angular, React, and Vue are different from each other [https://www.thirdrocktechkno.com/blog/angular-vs-react-vs-vue-which-framework-to-use-in-2020/] . We recently wrote a blog on when and why you should choose Reactjs for web development [https://www.thirdrocktechkno.com/blog/why-choose-reactjs-for-your-next-project-features-and-benefits/] . In this blog, we dig deeper and present to you top React libraries in 2020 that can be very beneficial while developing a Reactjs based application. The libraries/components are classified on the basis of their functionalities. Top React Library in 2020 For Routing and Navigation One of the key features of a web app is its ability to seamlessly navigate users from one page to another. However, this task becomes a bit complicated for the Single Page Apps (SPAs) [https://www.thirdrocktechkno.com/blog/single-page-apps-vs-multi-page-apps-what-to-choose-for-web-development/] . An SPA must be able to directly render that part of UI where the user interacts with the app while navigating through various sections. Therefore, SPAs use routers as guiding tools. The function of a router is to translate the browser address into related pages, thus helping the users to navigate through the web application. The SPAs resort to a very industrious approach of routing in which whenever a user takes an action on the web app, it collects new data. 1. React Router React Router [https://reacttraining.com/react-router/web/guides/quick-start] is a collection of navigational components that keep the UI of an application in sync with its URL. Thus, it ensures effortless navigation. Its API is simple yet effective with robust in-built features like lazy code loading, dynamic route matching, and location transition handling. Furthermore, it provides strong nesting support and server-side rendering. Top React Libraries in 2020 For CLIs and Boilerplates In simple terms, Boilerplates refer to the reusable blocks of code using which the developers can set up multiple libraries at once. It also allows them to generate identical copies for other projects that can be reused later. 2. Create React App Create React App [https://reactjs.org/docs/create-a-new-react-app.html] is a CLI tool that doesn’t require any building configuration. So it gives Reactjs developers a great head start when working on React projects as it enables the developers to generate their own boilerplates. The tool assembles the components and files needed to build, test, and launch an application. In this way, it drastically reduces the time and effort invested in the development process. One can initiate the app building process by simply running a single command and no more complexities are involved. Top React UI Component Libraries in 2020 An interactive and enticing user interface is a major factor in improving the retention rate of a web application. React has a good deal of UI component libraries for building captivating and feature-rich interfaces smoothly. 3. Ant-design Ant-design [https://ant.design/] is a UI library consisting of a set of tools for building elegant user interfaces. It has an extensive customer base and consolidates resources from NPM, Webpack, Babel and DVA. This React library offers a smooth user experience by allowing the developers to nest their UI components. It works better with internal desktop applications and is based on several unitary specifications. 4. React Bootstrap React Bootstrap [https://react-bootstrap.github.io/] is a Bootstrap library-based UI toolkit. It gives Reactjs developers more control over reusing and integrating UI components. Moreover, it has a lot of themes and resources readily available for use. The library is instinctive to use because of the Bootstrap themes and stylesheet. As a result, developers can code quickly and more productively with the help of reusable coding methods. 5. Material UI Material UI [https://material-ui.com/] is a set of components created by Google and is based on Material Design guidelines. It contains many accessible and editable UI widgets to create captivating, consistent, and light user interfaces. The components of Material UI are self-sustaining in nature and only implement the styles they need to display. This leads to performance enhancements in the applications. In addition to that, it has very strong community support. 6. Semantic UI for React Semantic UI React [https://react.semantic-ui.com/] is a jQuery-based component library that provides additional functionality to the pipelines used by the developers.  The library contains a bundle of prebuilt components that are designed particularly to generate Semantic-friendly code. It is a declarative API and strongly adheres to the flexible React ecosystem. Additionally, its shorthand props reduce the burden of hasty coding. Top React Libraries in 2020 For Animation The traditional way of implementing animations in a web app is through CSS. However, at times, many developers are limited by the use of CSS and look for additional tools for animation. Reactjs saved the day by offering an easy-to-use declarative UI that goes by the name React Transition Group. It permits the developers to execute the animations while creating a web app. Other examples of prominent React animation libraries are: 7. React-motion React-motion [https://github.com/chenglou/react-motion] is a well-known React animation library that employs spring configuration for defining animations. Thus, it relieves the developers of their concerns regarding controlled duration and complexities. The library streamlines the development flow within React components with the help of damping, stiffness, and precision methods. Moreover, its spring API bridges the gap between imperative and declarative approaches and guarantees a secured & shared transition. 8. React Native Reanimated React Native Reanimated [https://www.npmjs.com/package/react-native-reanimated] was created by re-writing the native animated API from scratch to make way for gesture-based interactions in the applications. The earlier React Native API faced problems in implementing gesture-based interactions. Therefore, this library was created as a better substitute. What’s better is that this library performs animations directly on the native thread instead of JS thread. Furthermore, it is backward compatible. This implies that the developers don’t have to recreate the animations for a specific component if and when they migrate to this library from the Animated API. Why Choose Reactjs For Your Next Project: Features and Benefits Read More [https://www.thirdrocktechkno.com/blog/why-choose-reactjs-for-your-next-project-features-and-benefits/] Top React Library in 2020 For Building Forms It is always easier to use a form element with a library instead of building it from scratch. Reactjs has several form libraries that can be used for better and faster creation of customized components including inputs, buttons, and even new components. 9. React Hook Form React Hook [https://react-hook-form.com/] Form is minimalistic and independent form library, mostly used with React hooks API. It is the most popular form library for Reactjs and is built with TypeScript. React Hook Form aligns the UI to the existing HTML standards which simplify form validation. Moreover, it unites the uncontrolled components with native HTML inputs. The library easily integrates with external React UI component libraries and Reactjs state management libraries. Top React Libraries in 2020 For Code Formatting Out of many code formatting libraries for React, the following two are our absolute favorites: 10. ES-Lint ES-Lint [https://www.npmjs.com/package/eslint-plugin-react] is a pluggable and configurable code analysis tool for JavaScript. In the React ecosystem, this library identifies the creases in JS codes that do not follow the standard guidelines. It improves the code by making it more consistent and bug-free. In addition to that, ES-Lint enhances the code quality by assessing the patterns in code and resolving the errors by auto-fixing the code. 11. Prettier Prettier [https://prettier.io/] is a code formatting tool that strictly abides by the current formatting rules. It supports multiple coding languages and integrates with most editors. It examines the files for issues and auto-reformates to make it consistent with the rules for indentation, quotes, etc. Termed as an opinionated code formatter, Prettier provides support for JavaScript, JSX, Angular, TypeScript, CSS, HTML, JSON, and many more. Top React Libraries in 2020 For State Management The purpose of state management libraries is to keep the state of all users uniform across different web forms. Meaning, a user can continue from the exact same location or page on a mobile device as he/she left it on desktop. 12. Redux Redux [https://redux.js.org/] is a state management solution for JavaScript applications. It’s a predictable state container and an autonomous library. Although it is primarily deployed with React UI components, it can also be used with Angular, Vue, Ember, and other frameworks. Redux is useful for both the front-end and the back-end libraries. The library makes it possible to connect the pieces of state to React components. Thus, it removes the need for callback or props. Reactjs developers love to work with Redux [https://redux.js.org/basics/usage-with-react] as it facilitates writing coherent codes, operates well in different environments, and supports easy testing. It also allows developers to edit the code live while working on a project. React Native, a mobile app development framework, has its official Redux library named React-Redux. 13. MobX MobX [https://mobx.js.org/] is a robust library created to simplify state management. Moreover, it makes state management more scalable by transparently applying functional reactive programming. The principle behind MobX is simple enough: anything which is derivable from the application state should be derived automatically and efficiently. The library acts as an easier and simpler substitute for Redux.  It is mainly used for quick-to-build and plain apps with lesser boilerplate code. Top React Library in 2020 For Payment Options With ever-increasing trends of remote shopping and simplicity of online payments, the numbers of online transactions have comfortably overtaken the cash transactions. The payment SDKs of Reactjs ecosystem offer a trustworthy solution for online payment to the end-users. 14. Stripe Elements Stripe elements [https://stripe.com/payments/elements] or API is primarily a feature of Stripe.js. It is a contemporary and adaptable UI components library for payment solutions in the Reactjs ecosystem. Stripe API boasts the features of data privacy and fast response with appropriate authentication. It runs on a single interface approach for Apple Pay, Google Pay, and payment request API. Stripe API proves its qualitative worth by offering a powerful performance of payment form and ease of making a custom form. It quickly responds to the payment acceptance and confirmation tasks with the help of dynamic card elements such as CVC, expiry, etc. Furthermore, it supports responsive design and language translation to suit the needs of the customer. Which is the best React library in 2020? We wish we knew the answer but the truth is there isn’t any one library that we can consider the best. That’s why we chose to write about top React libraries in 2020 on the basis of different categories.
