海外TECH	DEV Community	Is there a way to have raw-types in (modern) C++?	https://dev.to/baenencalin/is-there-a-way-to-have-raw-types-in-modern-c-2knd	Is there a way to have raw types in modern C What are raw types Raw types in Java is a type who has type arguments generics templates but whose type arguments are not specified in a declaration Consider the following Java code class NeverRaw NeverRaw int i this value i int value class PossiblyRaw lt T gt PossiblyRaw T v this value v T value class NeverRaw extends PossiblyRaw lt int gt NeverRaw int i this value i Some code later This isn t raw because a type argument is specified PossiblyRaw lt int gt notRaw new PossiblyRaw lt gt This IS raw because none are specifiedPossiblyRaw uncooked new PossiblyRaw lt int gt Invalid Mismatched types notRaw new PossiblyRaw lt float gt Valid No type mismatch because none is specified uncooked new PossiblyRaw lt float gt Why would you want types So the first thought that probably popped into your head is Hey Isn t that not type safe and to that I say Yes It can be unsafe at times But then it can also be utilized So Where can I use this Well here s where I m stuck I m implementing a Token type for Janky and I want to have a parse std string char function that returns an array of Token How is this a problem It s a problem because even if you want to return an array of something you must define the template arguments My Token type is written as such template lt typename T T v gt struct Token T value v TokenType type TokenType UNASSIGNED unsigned short col unsigned short ln And I can t create any abstraction since all pieces of this structure are important to have And because members aren t preserved when you say a piece of data is of its parent type So What s the best solution here Thanks Cheers	2021-10-24 22:29:33
海外TECH	DEV Community	How to create a Preloader in NextJS	https://dev.to/seven/how-to-create-a-preloader-in-nextjs-15n8	How to create a Preloader in NextJSThere s always a need to have all the content of a webpage ready before it is displayed to whoever is visiting your web app website In situations where the contents of the webpage aren t ready people would have to wait for it to be displayed and this causes a very high decline rate of people who visit your website In this article we ll have a look at how we can build a loading screen component that is displayed whenever the contents of the page is about to be mounted onto the DOM Before you read this article any further you should be familiar with React a declarative JavaScript library for building user interfacesNextJS a framework of React used for building production ready applicationsConditional rendering in ReactAnimations in CSS Getting startedIn this article we ll be using NextJS to set up our app you can use create react app if you are not familiar with NextJS Let us start by installing the dependencies that we need in this project We d start by creating a nextjs app The command below gets the dependencies that we need in a Nextjs app npx create next app name of your app We ll make use of the styled component library to style the loading screen component Let s get the dependency above by typing the command below into our terminal npm install save styled components The components in our Nextjs appIn this section we are going to see the different files that make up the architecture of this project and their respective functions below The pages directory is where all the routing of the app takes place This is an out of the box feature of Nextjs It saves you the stress of hard hard coding your independent routes pages api the api directory enables you to have a backend for your nextjs app inside the same codebase instead of the common way of creating separate repositories for your REST or GraphQL APIs and deploying them on backend hosting platforms like Heroku and so on pages app js is where all our components get attached to the DOM If you take a look at the component structure you ll see that all the components are passed as pageProps to the Component props too function MyApp Component pageProps return lt React Fragment gt lt Component pageProps gt lt React Fragment gt export default MyApp It is like the index js file in Create React App The only difference here is that you are not hooking your app to the DOM node called “root React render document getElementById root lt App gt index js is the default route in the pages folder When you run the command below it starts up a development server and the contents of index js are rendered on the web page npm run dev Building the loading screen componentThe previous sections walked you through the process of installing the dependencies that are needed for building the loading screen component and the functions of each file in a typical Nextjs app In this section we ll go through the step by step process of building the component itself First we ll be taking a look at the style of the loader We are using the styled component library for this purpose The Screen styled component serves as the parent container that wraps the loading animation It uses a fade keyframe to ensure the transition of the screen is properly utilized loadingScreen jsimport styled from styled components const Screen styled div position relative height vh width opacity animation fade s ease in forwards background black keyframes fade opacity opacity opacity The snippet below shows the Balls styled component It serves as a container for the child elements in it The corresponding divs in the container are the balls that we ll be animating You ll notice that there are unique classNames assigned to each div element in the container This is for us to be able to set an animation delay property on each ball so that the oscillating effect can be seen properly import styled from styled components const Balls styled div display flex position absolute top left transform translate ball height px width px border radius background b margin px animation oscillate s ease in forwards infinite one animation delay s two animation delay s three animation delay s keyframes oscillate transform translateY transform translateY px transform translateY If you re new to animations in CSS You can check this guide that explains the fundamentals Now that you have seen the styles of the components above We ll go ahead to reference the styles in the LoadingScreeen component below import React from react import styled from styled components const Screen styled div const Balls styled div const LoadingScreen gt return lt Screen gt lt Balls gt lt div className ball one gt lt div gt lt div className ball two gt lt div gt lt div className ball three gt lt div gt lt Balls gt lt Screen gt export default LoadingScreen Implementing the preloader functionalityWe ve seen the function of the loading screen styles and how the animation works behind the scene In this section we ll be importing the component into app js Take a look at it below import LoadingScreen from src components LoadingScreen function MyApp Component pageProps const loading setLoading React useState false React useEffect gt setLoading true setTimeout gt setLoading false return lt gt loading lt React Fragment gt lt Component pageProps gt lt React Fragment gt lt LoadingScreen gt lt gt export default MyAppThe snippet above shows how we ve used conditional rendering to check the state of the loading component We had to create a local state variable that holds the current state with the useState React hook const loading setLoading React useState false The initial state of the loader is set to a boolean value false The useEffect hook is a lifecycle method in React that is fired whenever there s a change in the DOM It combines all the lifecycle methods that a typical class based component will have React useEffect gt setLoading true setTimeout gt setLoading false By setting the initial falsy state of the loader to be true in the useEffect hook We re telling the browser to display the loader with the help of the setTimeout function for a duration of five seconds At the end of the timeframe the browser should ve loaded all the contents that need to be on the webpage ConclusionBelow is a GIF that shows what we ve been building all along Although this is an approach that helps us to have the content on a webpage site available If you are dealing with dynamic data say from an API endpoint the approach will be a little bit different You can decide to make use of this react spinners package if you don t want to spend time creating a custom loading component all by yourself Thank you for reading this article Kindly leave your thoughts in the comments section and share this article with your peers Thanks	2021-10-24 22:22:40
