海外TECH	DEV Community	4 Skills to Become a Front-end Developer in 6 Months (Road-map)	https://dev.to/codewithshahan/4-skills-to-become-a-front-end-developer-in-6-months-road-map-ldi	Skills to Become a Front end Developer in Months Road map Let me give you a simple Road map to know Where You Are and Where You Should to Go Next Building BlocksEvery website has a two parts A front end and a back end The front end is the part where you see in the browser and interact with All the visual aspects Back end is the part that powers the front end It s behind the scene and it s mainly about storing data and databases and providing it to the front end JobsSo web development jobs fall into three categories The front end developments back end developments and full stack developments which involves both front end and back end developments ‍Front end DevelopmentsFront end developers use HTML CSS and JavaScript Back end developers has different set of tools available to them So let s talk about HTML CSS and JavaScript HTML is short for hypertext markup language We use HTML to define building blocks of our web pages CSS is short for Cascading style sheet and we use CSS to making them beautiful JavaScript is used for adding functionality to the web pages Here is a real exampleLet s say you want to build an application like Instagram First we use HTML to define all the building blocks of the layout What are these building blocks is here an image some text or username another block of text for commenting sharing and liking So We use HTML to add these building blocks to our web pages Then we use CSS to give it visual effects For example we use CSS to make the font bold We can make our image around we can add some padding we can change the color of the icons and define their look when we hover over them So CSS is all about the statics or visual effects With CSS we can also create beautiful animation Now most web pages these days are interactive The response to our actions like clicks and scrolling This is where JavaScript s comes in With JavaScript we can add functionality and behavior to our web pages For example we can like a post So JavaScript is a programming language while the HTML and CSS are not We use them to define the building blocks of our web pages and style them Every webpage you have seen in internet is built with these three languages So the better you will learn and understand these languages and their features the better you will be at front end developments Front end Developer in Months So your front end development journey starts with HTML amp CSS I would say if you spend hours a day studying and coding you should be able to have a reasonable understanding these two language in about a month and a half Once you learn these languages you need to learn JavaScript I would say learning JavaScript would probably take another six weeks month of your time Of course you re not gonna be JavaScript experts in just six weeks But you will have a reasonable understanding and you will learn more as you work in different projects So the first three months is all about fundamentals Now building website often includes a bunch of repetitive tasks This is where front end frameworks and libraries come in A frameworks or libraries comes with a lot of code that you can reuse in our websites So they help us to get the job done faster That s why a lot of companies these days use one of these popular frameworks like React Angular or Vue Now we don t need to learn all of this to get started Different companies use different tools for their different projects As you move from one project to another you may want to learn about the other tools If you re starting out just focus on react Because it s the most popular tool in this space Once you learn react you can always learn the other tools if needed For React you would probably need one to two months All right what the next steps Version control systems We use version control system to keep track of our products history and work collaboratively with others There is many version control systems out there like Git Subversion Mercurial and so on But Git is the most popular tool in this space and it s used more than percent of software development s team That s why you see its almost all jobs description You would probably need another two weeks to learning Git ConclusionSo these are essential skills for every front end developer must have You ll see this list in almost every job description For now just focus on these four skills or four steps Remember less is more Don t try to learn too many things quickly You won t learn anything You will just waste your time Alright that s your Road map RecommendationIf you are interested in Front end developments and programming tips and tricks feel free to visit my YouTube Channel SpecialDo you want to learn programming without waste your time with lots of unnecessary theory or boring to do app tutorials amp Clear and concise courses with a perfect mix Here is a professional coding instructor that I love most Mosh HamedaniFeel free to leave a comment I am trying to helping othersHappy Coding	2021-08-01 08:53:01

海外TECH	DEV Community	Tagged Template Literals - The Magic Behind Styled Components	https://dev.to/dekel/tagged-template-literals-the-magic-behind-styled-components-2f2c	Tagged Template Literals The Magic Behind Styled Components Intro amp BackgroundIf you have some experience with React you probably came across styled components In the last few years the concept of css in js became more popular and there are multiple libraries that are available for us to use styled components is one of them but you can also find Emotion Radium JSS and more In this post I m not going to cover the pros and cons of traditional stylesheet files vs styled components and instead I m going to focus on tagged template literals the magic that let us use the styled components syntax styled component basics a quick reminderLet s take the following simple syntax for example The StyledDiv in the example above is actually a React component that returns a div block with the css of color red font weight bold Well kind of Actually it s a bit more complicated than that The output of the above is a div with specific css class names having the above css definitions inside Some of you are probably using this without giving it too much of a thought If we take a closer look we can see the usage of the backtick right after the styled div This syntax in Javascript is called Tagged Template Literals Template LiteralsLet s start with Template Literals and then move on to the more interesting concept In javascript template literals are strings that can contain expressions within them As you can see from the example above expressions can be variables but are not limited to them We can use either variable or function inside a template literal and the value that will be used is basically the string representation of the expression Now that we understand the power template literals it s time to move on to tagged template literals or just tagged templates Tagged Templates Whats the fuzz With tagged templates we have the power to parse the template literal ourselves using our own home made function Note that in the example above the variable strB contains the string String A and not String B as you might expect Let s break it downThe function funcA returns the string String A By using the function funcA as a tagged template we completely ignored the string that was sent and we just return something else We can use it with an empty string and the output will be the same Check it out Advanced featuresThe function we use in a tagged template can return everything that we want we are not limited to only return strings Building tagged templates have an option to also accept variables that can be used The first argument is a special object which behave as an array and provides access to all the native strings in the original string that was passed to the tag template function strings strings strings alongside a raw property which allows you to access the original raw strings The rest of the arguments are the expressions that we used inside the template literal Time to build let s start with something basicNow that we know a bit more about template literals it s time to move on to some more complex examples We already know that template literals don t have to return strings so how about creating a simple example of a tagged template that returns a react component with the relevant style We will start by creating a simple div example to just wrap our text with some styling on it The tagged template is the following code The full example is available here Check out the helper functions the cssObjFromStr we are going to focus on it in the next example Using props in the componentThe basic example gave us a nice intro but what about the component s props We use them all the time in React and losing them is not an option Moving to the next example we will add the option to also use props as part of our component that we would like to style We will use the onClick prop on the div element The full example is here Using props in the templateProps are not only relevant to the components but also to the template itself We want to use the props of the component inside the template itself colors elements behavior and more To do this we will need to pass the props from the lt Div gt to the cssObjFromStr method But this is not enough Let s assume that we use the lt Div gt element with the property textColor blue The issue we face here is that the lt div gt component inside the cmp will get the textColor property which is not a valid property of a div element A specific solution can be to extract the textColor from the props and pass the rest of the properties down to the lt div gt element Working example can be found here The styled components solution is a bit more elegant and much more generic all props that start with are considered private props and will not pass down to the actual jsx component We will use the same concept but in our example we will use the underscore to create private props Full working example can be found here SummaryThe styled component library contains much more than that with the entire built in HTML tags wrapped components classes and inheritance instead of inline style global themes and more however styled components is just an example of how to use the tagged template literals which is eventually just a native javascript feature as of ECMAScript also known as ES Cover photo by Gerd Altmann pixabay	2021-08-01 08:11:48
海外TECH	DEV Community	⚡ Speed-up your web with Blurhash	https://dev.to/meldiron/speed-up-your-web-with-blurhash-3mi8	Speed up your web with BlurhashAlongside this article I wrote a demo project made with Angular TailwindCSS and Blurhash You can check it out on Github Table Of ContentsIntroductionWhat is Blurhash Preparing a projectEncoding an imageDecoding an image Introduction Since I started working on e shops with hundreds of products on the website I have been looking for strategies to optimise the UX I started by adding loading animations but seeing the same rolling animation on ten places of a website is surely not the solution Then I found out you can use skeleton loaders to fill empty spaces with nice looking elements that represent actual data but are blank at the moment You can see this approach on dev to This is all you need for most websites but sadly this wasn t enough for me There was still a few seconds of loading time between when my data was loaded and when the images were rendered I could already see the name and price of a product but I didn t have pictures loaded yet Due to this whenever a new image got loaded the content jumped I tried to solve this by defining the size of an image and showing white space while the image was loading but that made the website feel really boring Finally I met Blurhash What is Blurhash Blurhash is a tool that takes our kb image and generates a B hash that can be used to generate a blurred version of an image You can easily store this hash as a text into your database and load it with every other text content such as article title or author name This comes really handy when working with any images because you don t have to be creative about What will I do while images are loading Instead of creating empty space you simply take Blurhash of an image and show the blurred version while the image is loading Preparing a project I started by creating an empty Angular project with TailwindCSS and Blurhash library installed First I defined my array of images This simulated data that I would receive from an API so I can start working on the blurring algorithm images name Fastest car ever url ixlib rb amp auto format amp fit crop amp w amp q name Let s eat url ixlib rb amp auto format amp fit crop amp w amp q name Who doesn t love dogs url ixlib rb amp auto format amp fit crop amp w amp q name We love cats too url ixlib rb amp auto format amp fit crop amp w amp q After adding some basic HTML with Angular data binding I was able to get the images rendered To confirm what Blurhash can do in numbers I decided to write a tiny script that loads the file size of our images and presented it in the HTML Calculate original image sizefor const image of this images const fileSize number await new Promise resolve reject gt var http new XMLHttpRequest http open HEAD image url true http onreadystatechange function if this readyState this DONE if this status const fileSize this getResponseHeader content length resolve fileSize fileSize http send image originalSize fileSize Looks good to me let s start using Blurhash When working with Blurhash you split the job into two parts ENCODE and DECODE Encoding an image Before using the blur hash I need to have the hash right Encode function of Blurhash library takes an array of pixels with their colour UintClampedArray and returns a simple string that represents newly created hash for our image To provide the correct input to the function I need to render our image inside a virtual canvas and extract data about the pixels in the canvas private async generateBlurhash imageUrl string Promise lt hash string width number height number gt const loadedImageObject HTMLImageElement await new Promise resolve reject gt const img new Image img setAttribute crossOrigin img onload gt resolve img img onerror args gt reject args img src imageUrl const canvas document createElement canvas canvas width loadedImageObject width canvas height loadedImageObject height const context canvas getContext d context drawImage loadedImageObject const imageData context getImageData loadedImageObject width loadedImageObject height if imageData throw Error Could not render an image return hash encode imageData data imageData width imageData height width loadedImageObject width height loadedImageObject height Now I used this function to add hash attribute to our array of images for const image of this images const blurhashData await this generateBlurhash image url image hash blurhashData hash image height blurhashData height image width blurhashData width Hmm that wasn t too bad Few lines of code and the hashing function is ready When preparing this project I noticed that hashing is a pretty CPU heavy method and takes almost second to finish It is up to you to decide whether you want to use the client s CPU or do the hashing on the server Anyway keep in mind this only needs to be done when uploading an image so you don t need to worry about extreme load on the backend Decoding an image Once I had the hash of an image I needed to do the exact opposite I needed to convert our string input into image output I started with a simple decode function provided by Blurhash library Alongside the image hash I provided the expected width and height of hashed image const blurhashPixels decode image hash image width image height This function returns a loooooooong array in which every four items represents the RGBA red green blue alpha value of a pixel You can imagine this as a D definition of our image Although our D array od pixels is pretty useless to us the canvas can easily convert it into an actual image if we tell it the width and height of our D array const blurhashCanvas HTMLCanvasElement lt HTMLCanvasElement gt document getElementById blurhash canvas imageLoopIndex const ctx blurhashCanvas getContext d const imageData ctx createImageData image width image height imageData data set blurhashPixels ctx putImageData imageData Finally I put everything together hook it to an HTML template and add some delays so I can see what is going on The result is stunning check it out If you are lost and unsure how some parts work together please check out my Github project that contains the whole application I built alongside this article Snippets in the article were taken from the project to quickly showcase the specific logic of Blurhash That s it for now If you are interested in cool new technologies feel free to follow me and you will be notified whenever a new post is published	2021-08-01
