There are many ways to conduct a technical interview, and they depend from company to company. You might get whiteboard designing of architecture system, writing an algorithm, or some coding challenge. After working with multiple companies and going through many interviews from both sides, I prefer coding ones. More specifically, making something like a to-do application. By doing it, in an hour, I can assess if a person is junior, mid-level, senior, or architect. In this text, I cover how I do it and what knowledge I expect for which experience level. Application to build I prefer a to-do application. The model for an item of it is straightforward. All you need is a text, a unique identifier, and some flag indicating its status. All to-do applications display the list of all items, enable input of a new item, toggle the item’s status, and delete them. I don’t expect to spend more than 45 minutes up to an hour. That is not a long time, so I don’t expect candidates to do everything, just enough to show how they think and what they know. I provide candidates with initial data. It is just a JSON file with few items located in the public folder. In React, every file located in that folder is available, and this one you can request by making a get request to /todo.json. I am okay with googling for documentation, and I make it clear at the beginning of the interview. And this is also an indicator of candidate experience level. If the candidate checks documentation for some API, that is fine. But if the candidate...
Single page apps demand the front-end developers to become better software engineers. CSS and HTML are not the biggest concern anymore, in fact, there is no longer just a single concern. The front-end developer needs to handle XHRs, application logic (models, views, controllers), performance, animations, styles, structure, SEO, and integration with external services. The result which emerges from all those combined is the User Experience (UX) which should always be prioritized. AngularJS is a very powerful framework. It is the third most starred repository on GitHub. It is not difficult to start using, but the goals that it is intended to accomplish demand comprehension. No longer can AngularJS developers ignore memory consumption, because it will not reset on navigation anymore. This is the vanguard of web development. Let’s embrace it! Common Mistake #1: Accessing The Scope Through The DOM There are a few optimization tweaks recommended for production. One of them is disabling debug info. DebugInfoEnabled is a setting which defaults to true, and allows for scope access through DOM nodes. If you want to try that through the JavaScript console, select a DOM element and access its scope with: It can be useful even when not using jQuery with its CSS, but should not be used outside of the console. The reason being that when $compileProvider.debugInfoEnabled is set to false, calling .scope() on a DOM node will return undefined. That is one of the few recommended options for production. Please note that you can still access the scope through the console, even when on production. Call angular.reloadWithDebugInfo() from the console and the app will do just that. Common...
When getting started on developing a mobile app, it’s easy to get carried away thinking about how your app will look and function, , and the overall value you imagine it bringing to your users. But one of the first things you should be thinking about is what type of app you’ll build. There are native apps, hybrid apps, web apps, and progressive web apps. Choosing the right type is crucial to bringing your dream app to life, so think carefully about the decision. In this article, we’ll bring you up to speed on the different types of , the technology behind them, and how to make the right choice. Chapter #1: Native Mobile Apps When you hear the term “native app”, this simply means that the mobile application was built for a specific operating system (OS). Most mobile devices use either iOS or Android OS. So creating an app that’s native to one of these systems means making the most of the device’s functionalities. With that said, , for example, can’t be used for other platforms, like Android devices. 1.1 How Native Apps Work First and foremost, native apps are coded using like Kotlin, Java, Swift, and C++. They function by having complete access to a device’s hardware and functionality. The platform provides developers with a set of standardized tools, libraries, code samples, and documentation, also known as a software development kit (SDK), that will help them create an app for that specific platform. Platforms also provide an integrated development environment (IDE) for developers to use to write and test their software. This is a software suite that...
Hello friends, welcome back to my blog. Today in this blog post, I am going to show you, Reactjs Shopping Template Free. Reactjs Shopping Template For reactjs new comers, please check the below link: Reactjs Basic Tutorials Friends now I proceed onwards and here is the working code snippet for Reactjs Responsive Sidebar Template Free and please use this carefully to avoid the mistakes: 1. Firstly, we need fresh reactjs setup and for that, we need to run below commands into out terminal and also we should have latest node version installed on our system: npx create-react-app reacttepmate cd reacttepmate npm start 2. Now we need to run below commands into our project terminal to get bootstrap and related modules into our reactjs application: npm install bootstrap --save npm install jquery --save npm install popper.js --save npm start //For start project again 3. Finally for the main output, we need to add below code into our projectname/src/App.json file or if you have fresh setup then you can replace projectname/src/App.js file code with below code: import React from 'react'; import './App.css'; //Bootstrap4.5 import 'bootstrap/dist/css/bootstrap.min.css'; import 'bootstrap/dist/js/bootstrap.min.js'; class App extends React.Component { render() { return ( <div className="MainDiv"> <nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top"> <div class="container"> <a class="navbar-brand" href="#">Therichpost</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul class="navbar-nav ml-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span> </a> </li> <li class="nav-item"> <a class="nav-link" href="#">About</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Services</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Contact</a> </li> </ul> </div> </div> </nav> <div class="container"> <div class="row"> <div class="col-lg-3"> <h1 class="my-4">Therichpost Shop</h1> <div class="list-group">...
Building a GraphQL API with ASP.NET Core 2 and Entity Framework Core Published Mar 29, 2018 • Updated Mar 26, 2020 GraphQL is a relatively new technology developed initially at Facebook and open-sourced to the world in 2015. In 2017, it really took off and made the leap from a cool, niche technology to one of the primary ways companies like Walmart and IBM are starting to work with their APIs and data. If you’re new to GraphQL, here’s a definition that sums it up nicely. GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. GraphQL isn’t tied to any specific database or storage engine and is instead backed by your existing code and data. The last sentence is an important one to be mindful of when getting started with GraphQL. So, I’ll repeat it by saying GraphQL is not any specific framework or database but rather a that describes the capabilities and requirements of data models in client‐server applications. There’s a growing number of libraries out there to help you implement the GraphQL spec in your app for a number of different languages. In this post, we’ll learn about designing and building a GraphQL powered API using ASP.NET Core 2, Entity Framework Core and Joe Mcbrides’s excellent graphql-dotnet library. Benefits of GraphQL Before we dig into the code, it’s worth pointing a few fundamental issues with REST that GraphQL solves and why we may want to choose it over a traditional REST approach in certain scenarios. 1. GraphQL Is Less Chatty than...
