海外TECH	DEV Community	Make your own blog site with GatsbyJS	https://dev.to/justdev_sim/make-your-own-blog-site-with-gatsbyjs-5em6	Make your own blog site with GatsbyJSAs a part of the DaysOfCode challenge I decided to create a blog to document my journey with the challenge This blog is built using GatsbyJS and I learned the basics of Gatsby in a couple of days If you know ReactJS Gatsby is easy to catch on to Without further ado let s dive into how you can develop a blog just like this for sharing your own thoughts and journeys Table of ContentsWhat is GatsbyJS What are starters in Gatsby System PrerequisitesDeveloping the site What is GatsbyJS Gatsby is a React based open source framework for creating websites and apps What are starters in Gatsby To develop our blog we will be using the gatsby starter blog starter but what is a starter It is a boilerplate Gatsby site that helps jump start the development process Starters are maintained by the community for the community System PrerequisitesYou need to perform the following installations on your system before you begin with the development Node js preferably the LTS version After you install Node js open your terminal or command prompt and install gatsby cli using npm with the commandnpm install g gatsby cliTo facilitate deployment and to make your repository on GitHub you need to download and install git ORUse CodeSandbox to develop right from your browser Creating and setting up the project is significantly easier and hassle free in a sandbox Will not be using this method in this blog We re all set to begin development Developing the site Steps to developCreate a new gatsby project and install the starterRun the website locallyCreate a GitHub repository and push the code to the repositoryChange author details in gatsby config jsCreate your first blog post Step Create a new gatsby project and install the starterUsing your terminal navigate to the directory where you want to create the project To create a new project we use the gatsby new command we can install the starter in ways gatsby new project name starter repo link gatsby new project name GithHub username repo name For example I want to call my project my blog gatsby new my blog gatsby new my blog gatsbyjs gatsby starter blog Step Run the website locallyNavigate to your project directory in the terminal gt cd my blogInstall all dependencies using npm or yarn my blog gt npm installOR my blog gt yarnRun gatsby develop The terminal output will look like this success open and validate gatsby configs load plugins s success extract queries from components ssuccess write out requires ssuccess run page queries s s⠀You can now view my blog in the browser ⠀ http localhost ⠀View GraphiQL an in browser IDE to explore your site s data and schema⠀ http localhost graphql⠀Note that the development build is not optimized To create a production build use gatsby build⠀success Building development bundle ssuccess Writing page data json files to public directory s sThe website will now be accessible at http localhost As long as the development server is running you can view your website here It automatically recompiles every time you save changes as long as gatsby develop is running The GraphiQL interface at http localhost graphql It is okay if you don t have experience working with GraphQL I have yet to learn it and it is not needed to build this blog thanks to the starter Step Create a GitHub repository and push the code to the repositoryNavigate to the project directory in the terminal Run the command git init to initialise a local git repository Run git add all to add all files to git Run git commit m create initial commit to commit these files to the repository Now sign in to GitHub and create a new empty repository Copy the link to the repo For example In your terminal in your local repository run the following command to link to GitHub repo git remote add origin repo link Here replace the repo link with the link copied in the previous step Push the initial commit to GitHub using the command git push u origin main Our repository is now on GitHub Now let s make some changes so that the blog is ours Step Change author details in gatsby config jsOpen the file my blog gatsby config js in your favorite editor I use VSCode The file contains a module exports object within which the siteMetadata is there It should look like this siteMetadata title Gatsby Starter Blog author name Kyle Mathews summary who lives and works in San Francisco building useful things description A starter blog demonstrating what Gatsby can do siteUrl social twitter kylemathews Replace with your details except for siteUrl for now like so siteMetadata title Simran s Blog author name Simran Makhija summary who lives and studies Computer Science in Indore India description My blog for sharing all things tech and community built with GatsbyJS as a part of DaysOfCode siteUrl social twitter justdev sim Replace src images profile pic png with your own picture Make sure the name of the image is profile pic png Now the blog has your name title info and image The site will now look like this Step Create your first blog postNow let s take a look at how our blogs are stored and organised The content blog directory stores all your blog posts Each blog post has its own subdirectory The name of this subdirectory corresponds to the route at which the blog will be rendered For example The blog within the hello world folder can be found at base url hello world http localhost hello world on our local server The index md file contains the markdown source for your blog The default hello world contains a markdown cheatsheet of sorts that I have stored in a separate file and refer to for syntax Now let s go ahead and write our own first blog Delete all folders within content blog Create a new folder hello world Within this folder create a new file index md This is where we ll write our markdown source In the file add the frontmatter title Hello World date T Z description Hi I am a student developer Nice to meet you This front matter corresponds to the name date and blog description we see on the home page like so Below the frontmatter you can include the entire content of your blog Here s how my content blog hello world index md looks title Hello Worlddate T Z description Hi I am a student developer Nice to meet you Hi I am Simran Makhija ‍ ️Nice to meet you I am a final year Computer Science amp Engineering student from Indore India ‍ Thank you for dropping by Save all changes and push them to your GitHub repository This is it on developing the blog site Hope it was easy to follow and helpful In my next blog I will be writing about deploying this site to the internet Thank you for reading See you then	2021-11-30 14:25:24

海外TECH	DEV Community	How to Analyze and Improve your 'Create React App' Production Build	https://dev.to/alexeagleson/how-to-analyze-and-improve-your-create-react-app-production-build-4f34	How to Analyze and Improve your x Create React App x Production BuildIn this tutorial we re gonna take a step by step look at how to analyze and optimize your Create React App project using a custom webpack configuration that is extremely easy to set up We will be using examples that make small adjustments and try different ways of importing modules and splitting your code to see the direct impacts it has on your bundle sizes and performance The goal here is to help you get a better understanding of what webpack is actually doing by seeing the exact changes that occur to a production build when you make small changes to your application To begin we ll create a brand new React app called something big and bloatednpx create react app something big and bloated template typescriptNext we ll install the dependencies we need to analyze the project npm install craco craco webpack bundle analyzer save devcraco A tool to use a custom webpack configuration with Create React Appwebpack bundle analyzer A webpack plugin for analyzing bundle sizeWe need to create a configuration file for craco in the root of our project to include our webpack plugin craco config jsconst BundleAnalyzerPlugin require webpack bundle analyzer BundleAnalyzerPlugin module exports function return webpack plugins new BundleAnalyzerPlugin analyzerMode server If we run the usual npm run build script for a production build it will use the standard react scripts method However if we run craco build it will still run the same process but inject in any webpack configuration you have included in your craco config js file Pretty sweet Let s give it a try We ll create a new entry called analyze in package json scripts scripts start react scripts start build react scripts build test react scripts test eject react scripts eject analyze craco build Now run npm run analyzeBecause we set the analyzerMode to server in our craco config we will automatically get our browser open with the results served as a webpage you can use the json option if you want the output without involving the browser You can hover over each module within the chunks or your can use the little arrow at the upper left which pops out a drawer You ll get three different values stat The size of the original source codeparsed the size of the same code as compiled bundlesgzipped the size of the compiled bundles after being gzippedSo for most deployments you can look at the gzipped value as how much network usage you will need and the parsed size as how much code the browser is going to handle once unzipping is complete Be aware that this value can be just as problematic on users with less powerful CPUs as the gzip size can be for those on slow networks Both are important to consider On create react app v for this tutorial the values I get are kb kb kb for stat parsed gzipped respectively You can see right out of the box we get a bit of overhead though for most users that s a small price to pay for convenience Now let s try adding some libraries and look at how this value changes We ll consider the way that we do our imports and see how we might be able to better control our bundle size by only importing what we need I m gonna pick a fairly popular UI library called MUI Material UI It s a good example of a large package that significantly weigh down your app if not bundled properly It will make a good example for our tutorial We will need the following packages mui material A React component library designed to give you some useful pre styled components out of the box mui icons material An icon package for MUI based on material icons emotion react Required for mui material emotion styled Required for mui material npm install mui material mui icons material emotion react emotion styled saveBefore we even do anything let s run our analyzer again Remember we ve added these libraries but we aren t actually using any of them yet Do you think our bundle size will increase Let s find out npm run analyzekb kb kb again Exact same result That s great That means that webpack is not including any libraries we don t actually use It s doing its job well Now we ll import a component from MUI We ll grab a relatively complex one something more than a button Let s use the Speed Dial Create a new component file in src src CustomSpeedDial tsximport React from react import Box from mui material Box import SpeedDial from mui material SpeedDial import SpeedDialIcon from mui material SpeedDialIcon import SpeedDialAction from mui material SpeedDialAction import FileCopyIcon from mui icons material FileCopyOutlined import SaveIcon from mui icons material Save import PrintIcon from mui icons material Print import ShareIcon from mui icons material Share const actions icon lt FileCopyIcon gt name Copy icon lt SaveIcon gt name Save icon lt PrintIcon gt name Print icon lt ShareIcon gt name Share export default function CustomSpeedDial return lt Box sx height transform translateZ px flexGrow gt lt SpeedDial ariaLabel SpeedDial basic example sx position absolute bottom left icon lt SpeedDialIcon gt gt actions map action gt lt SpeedDialAction key action name icon action icon tooltipTitle action name gt lt Box gt Replace the contents of your App tsx file with the following src App tsximport React from react import CustomSpeedDial from CustomSpeedDial function App return lt CustomSpeedDial gt export default App Run the development server to check it out npm run startEverything looks good Let s see how much that impacted our build RUn our analyze command again npm run analyzeOur bundle size is now up to kb kb kb That s a significant increase for one component Of course bear in mind that it s fairly complex and as soon as you use one you need to include all the other dependencies that make MUI function I d bet if you added a second component you wouldn t get such a big jump In fact we can try now Add the following to your SpeedDial component src CustomSpeedDial tsx import React from react import Box from mui material Box import SpeedDial from mui material SpeedDial import SpeedDialIcon from mui material SpeedDialIcon import SpeedDialAction from mui material SpeedDialAction import FileCopyIcon from mui icons material FileCopyOutlined import SaveIcon from mui icons material Save import PrintIcon from mui icons material Print import ShareIcon from mui icons material Share NEWimport Button from mui material Button const actions icon lt FileCopyIcon gt name Copy icon lt SaveIcon gt name Save icon lt PrintIcon gt name Print icon lt ShareIcon gt name Share export default function CustomSpeedDial return lt Box sx height transform translateZ px flexGrow gt NEW lt Button variant contained gt Hello world lt Button gt lt SpeedDial ariaLabel SpeedDial basic example sx position absolute bottom left icon lt SpeedDialIcon gt gt actions map action gt lt SpeedDialAction key action name icon action icon tooltipTitle action name gt lt SpeedDial gt lt Box gt We ve imported a button above and included it with our speed dial two new lines marked with NEW comments When we run npm run analyze again we get almost the same kb kb kb We can see that the button extremely little to the bundle size since most of the building blocks for it were already included with the Speed Dial But now let s compare when using the traditional commonJS import Add the following line to the very top of your CustomSpeedDial component if ESLint complains about import order place the line after all your imports statements src CustomSpeedDial tsxconst material require mui material Analyze again npm run analyzeHoly moly MB kb kb What happened Looks like we re bundling the entire MUI library Popper Tooltip js We re not using any of those but they re taking up a ton of space in our chunk It turns out that when we are using ES modules webpack is very good at figuring out which pieces of code we are actually using based on what we import and export This process is called tree shaking and it requires you to use ES modules in order to work You can see that doing so can have a very dramatic effect on our final bundle Our current program is exactly the same functionally as our previous one but thanks to a single commonJS import it s a whopping x the size Yikes Here s what we re going to do though Instead of removing that require in our CustomSpeedDial we re going to leave it there and introduce something called code spltting as another option available to you Code splitting is effective when you have a certain component or page or general part of your application that isn t necessary required for every visitor It might be a datepicker that only appears when a user makes a booking or it might be a help page that only a small percentage of users will need We can use React s lazy and suspense features to break these pieces into separate bundle chunks and only load them when necessary Let s update App tsx There s a lot to unpack here so we ll just show the code first and break it down src App tsximport CircularProgress from mui material CircularProgress import Button from mui material Button import React Suspense useState from react const CustomSpeedDial React lazy gt import CustomSpeedDial function App const showSpeedDial setShowSpeedDial useState false if showSpeedDial return lt Suspense fallback lt CircularProgress gt gt lt CustomSpeedDial gt lt Suspense gt return lt Button variant contained onClick gt setShowSpeedDial true gt Click to load speed dial lt Button gt export default App The numbers are a little out of order but that s intentional You ll see it follows the actual flow of the component We lazy import the CustomSpeedDial module Remember that s the one that uses require for the entire MUI package and comes in at MB By using the lazy import what happens is that the import only occurs when our primary component here CustomSpeedDial actually tries to render it We ll see that it doesn t by default A boolean React state value to keep track of whether which component we want to render The default false value means we will not be rendering CustomSpeedDial Our default component is a basic Button imported directly from MUI When this button is pressed it sets the value of showSpeedDial to true Once showSpeedDial is true we take this branch at the next render The reason we get a re render is because we updated a stateful React value showSpeedDial The purpose of the Suspense component is to tells React what to render while waiting for the module to import Depending on the size it could take a second or more For our example we are using MUI s CircularProgress to imply a loading state while the module is loading Once it loads it switches to render the children of the Suspense component Now it s time to try it out We ll begin with an analyze npm run analyzeThis gets really interesting Webpack has created new separate chunks You ll notice there are more js chunks when you toggle the drawer on the left In fact this largest chunk on the left dae chunk js mb kb kb isn t even used on the default load of our app Based on our learnings earlier we can see that huge chunk is definitely our CustomSpeedDial tsx component that imports all of MUI with require commonJS import On the right we have the much smaller bundle c chunk js that includes things like Button and ButtonBase This is the chunk that will load on every page load We can look at the size and validate that in a moment Since our ultimate goal is to make sure our production app is running as efficiently as possible we want to run our tests on the production version of the app Use the following command to build a production version of the app bpm run buildNext we ll need to serve that build directory that was created If you have your own local serve you prefer to use use it If not just add the serve package npm install serve save devAnd then use it to serve the build directory npx serve buildYou can find the page at http localhost or whatever port serve specifies on the command line Press F to open your browser s Developer Tools and click the Network tab THis process should be roughly the same in both Chrome Edge and Firefox I am using Firefox so the screenshots should match your experience If you are using another browser the options will still be there just potentially in a different location Click the Disable Cache checkbox so that we are loading the JS files on every refresh and not a cached version from the browser We want to be able to see the load times and sizes Now hit the refresh button F As we predicted our total transfer is KB with KB of that being the highlighted smaller c chunk we identified remember this is a served production build so we are working with GZIP sizes just like your real app would for real users There is no sign of the KB gzipped chunk Let s click the load speed dial button on our app There s that KB chunk with our CustomSpeedDial component inside of it How cool is it that it only loaded the code on demand Wrapping UpI hope you can start brainstorming ways to reduce the bundle size of your app and potentially introduce code splitting to improve initial load times Also worth noting these tips are not exclusive to Create React App All we did was introduce a special tool called craco to allow us to configure webpack Any application running webpack can potentially benefit from these tips It would be irresponsible to me not to mention that Create React App does recommend a similar tool that doesn t require craco although personally I feel it s not as intuitive to read the data it still gets the job done well Read about it here Continue LearningPlease check some of my other learning tutorials Feel free to
