海外TECH	DEV Community	Next.js for beginners	https://dev.to/anshuman_bhardwaj/nextjs-explained-for-beginners-c2g	Next js for beginnersAt the time of writing this article Next js is already a widely known framework for React applications Honestly there are tons of reasons for it to be popular and widely adopted but I m not gonna go into that rabbit hole for today I ve done it many times already Instead I m going to walk you through a series of questions don t worry I ll answer them with you to explain it better Disclaimer When I say for beginners I mean beginners in Next js This article is meant for developers who have been doing React for a while and who want to get serious in Application development with React So if you don t know the fundamentals React reading up React Docs instead would ideal If you ve made up your mind to proceed let s get the party started What s Next js Next js is a React framework that provides additional optimizations and configurations out of the box for developers But what does that mean To answer this better we should answer another question first Why is Next js The answer to this question starts with What is React man now you just going in circles bear with me my friend React is a library for building web applications in a declarative fashion React does a lot of things for us it has great community and support but what it lacks is opinion It s a library so it s minimal by definition and leaves a lot of heavy lifting on the developers like routing asset management and optimizations like code splitting While this gives a lot of flexibility it also leads to bad choices and poor application organization This is where Next js comes into the picture It gives the right set of tools and guides you with a process to make the most out of them It provides built in support forDirectory based routingPre rendering to HTML for SEO Search engine optimization SSR server side rendering at request time SSG static site generation at build time API routesMiddlewaresImage optimizationCode splittingto name a few It does all of this while keepingdeveloper experience optimalmaintenance overhead to a minimum How s Next js Wait wait before you get started about my bad English because you didn t watch Avengers Infinity War I d request you to watch this video so you get the joke that s really important to me Coming back to the question well Next js does it by covering up the things developers want while building upon what React has provided For example React is great at developing applications with declarative code but it sucks at routing as it doesn t have its own Next js provides a great solution for path based routing Next js became quite popular at first by solving the SEO problem with client side applications including React Ideally React applications are rendered on the client browser which has a couple of drawbacks likeslow initial load due to large bundle size and JavaScript execution on the clientbad SEO due to client side renderingunnecessary network calls from client sideNext js solves this by pre rendering React applications before sending the response to the user Pre rendering is compiling React components into their HTML layout on the server side Pre rendering makes the user experience better asit delivers a smaller JavaScript bundle which reduces the time to download and process it on the client siderendering on the server is fast because of better computing powerdata fetching on the server saves us from network calls waterfall on the client on top of that it ll be much faster if the data source is the Next js API routesNext js provides two methods of doing pre rendering SSR which generates the HTML at the request time good for pages using live data and SSG which generates the HTML at the build time better for static pages The below diagram explains the difference between CSR Client Side Rendering vs SSR Server Side Rendering vs SSG Static Site Generation Both SSR and SSG enables us to leverage the simplicity of React without compromising on user experience Next js being the great framework it is picks the best rendering strategy for you based on how you ve have structured your page This makes Next js a powerful framework for delivering production ready applications with React As you can already see my love for Next js very hard to hide I ll be unleashing this love by continuing this Next js beginners course in a series of articles and YouTube videos We ll discuss Next js fundamentals in detail and build a production ready application with Next js including development and deployment So make sure to follow me to get latest updates I hope you find this article helpful Should you have any feedback or questions please feel free to put them in the comments below For more such articles follow me on TwitterUntil next time	2022-04-18 07:18:04
海外TECH	DEV Community	A tour with Dart syntax - Dart programming - Part 2	https://dev.to/hoangnguyen0403/a-tour-with-dart-syntax-dart-programming-part-2-136l	A tour with Dart syntax Dart programming Part Hello It s FlutterWithMe again After a previous article for introduce overview about Dart This article i ll move on Syntax in Dart to help you more understand about dart programming Let s start with following basic code void printInteger int aNumber print The number is aNumber void main var number printInteger number main is the special required and top level function where app execution starts Every app must have a top level main function var is a way to declare a variable without specifiy its type But do you know the difference between var and dynamic Let me quick compare to you guys dynamic can change TYPE amp VALUE of the variable later in code var takes the type of the value that is first assigned and doesn t allow the type to be changed only can change value Dart is smart enough to know exact type when you declare var with variable On previous example type of number is int void printInteger int aNumber is a way to declare function Dart is a true object oriented language so functions are object and have a type On previous example function type is void so no have return variable on function print message is a function to display output to console log Below are these keyword that Dart language treats specially Avoid using these keyword as identifiers Now these are important concepts when you learn Dart languages Everything you place in a variable is an object If you enable null safety variable can t contain null unless you make it can You can make a variable nullable by putting a question mark at the end of its type Example int number That s mean number variable can be int type or nullBut if you do like this int plusNumber number That s mean you re force number never null with comma And if number null it ll through an exception So avoid doing like that if you not sure about data can null or nut Dart support generic types like List or List that s depend on type you pass into generic comma Unlike java Dart doesn t have keyword public protected private If an identifier start with underscore it s private to this class int number This is public variableint number This is private variableRemember to check dart analyze for make a better code Because it ll follow to dart coding convention rules Which i ll talk about in other article I think it s enough to understand about dart syntax To sum up about dart syntax Support top level functions Have null safety which help us avoid NullPointException like java when get null value Dart define private variable with underscore Remember to check dart analyze frequently for better code convention So thank you for spend time reading some of my dummy article I want to take a good preparation before going into some awesome knowledge about Flutter in the future If you have any advise or comment please let me know so i can update and sharing my knowledge more easy understanding	2022-04-18 07:17:57

海外TECH	DEV Community	How I build my own stand-up reminder	https://dev.to/nithyanandam/how-i-build-my-own-stand-up-reminder-45i4	How I build my own stand up reminderBefore we get into details let me put out the reason behind this effort As the pandemic hits and WFH starts my physical activity has been reduced drastically And I was spending even more time on my desk compared to the office environment Since my entertainment also lies within my desks such as gaming and reading The continuing situation put a toll on my back hence I decided to act on it As the saying goes start small I have narrowed down the possible option to improve my physical activity and decided to follow it up The simplest one is standing up at regular intervals after sitting down at the desk for a while This is something that can be accommodated easily in the schedule right Hence I picked it up and searched for a stand up reminder on google Unfortunately there are not any simple options present to use effectively on my laptop And yea obviously I don t want to extend this into my smartphone As my digital time is already too high and also it would easily make me get distracted by my smartphone Ok time to get hands dirty So in hindsight I planned out a simple HTML page that can load out an audio video in a set period of interval time and keeping the chrome tab on would be the only downside of it I thought also dumped the idea of using audio since I couldn t find any proper web API to get audio content Decided to go with youtube video as it was an easy option So coded out a simple HTML page and when I tried to autoplay on the iframe Chrome was smart enough to not let me autoplay the video with sound as an access policy Even though that made me annoyed kudos to chrome which doesn t want to annoy the user by playing autoplay video even worse if the user is not even in the tab he would have to go through all tabs and figure out where the sound was coming from So it was a pretty good fix and access policy from chrome What I thought would be a mins work taught me about chrome access policy and youtube embed options Now I am almost stuck and also I don t want to spend more time on it Time to rethink my decision Ok now let s ditch chrome and go for a native app Do I know native desktop app development no obviously Currently is there any place where you can t run javascript Here comes the saviour electron Going to do the same implementation but just going to transfer it to the native app According to my assumption it should work Again there is no time to learn the design fully Took out the hello world example and modified it a little specifically removing the same origin cors policy meta in HTML to load out the youtube video Hola It worked like a charm Set your duration in minutes Put your favourite video URL from youtube Our Standup Reminder is ready to go Minimize the app and do your stuff Once the time interval hits the video will play automatically For example you can set it to minutes and it will play every one hour interval and you can use it to remind yourself to take a break and stand up Don t want the reminder just close the app Was it too much to do for a simple stand up reminder Might be but why not have fun when you can So this is how I build my own stand up reminder It took an hour almost Was it worth doing absolutely Want to check out the project and use it for yourself Check out the repo Should I polish it out and publish it as an app and share it with non programming folks let me know in the comment Have any feature ideas for this please feel free to let me know	2022-04-18 07:11:27
