海外TECH	DEV Community	Getting Bundling Superpowers Using Codegen	https://dev.to/florianrappl/getting-bundling-superpowers-using-codegen-2no8	Getting Bundling Superpowers Using CodegenPhoto by TK on UnsplashNo matter if you write a frontend application a backend application or some tooling in JavaScript or TypeScript you ll eventually end up with a bundler to actually optimize your assets for delivery Bundling can not only transpile files such as going from TypeScript to JavaScript combine multiple files concatenating different modules by wrapping them in functions and remove unused code it can also remove dependencies from your package This is an easy way of reducing the weight of an npm package The general working principle of a bundler is shown below No matter why you use a bundler in this article I ll show you yet another trick you will be able to do with the bundler of your choice Use codegen modules to actually dynamically insert modules at bundling i e build time these modules can be actually generated on the fly Let s start with a simple example Example Inserting Package InformationThe situation is simple You are tasked to add two static pieces to your frontend application namelyThe name of the application from the package json andThe version of the application from the package json Luckily almost all bundlers support importing json files They are treated like a module default exporting an object i e the JSON content In code this could look like import name version from package json console log The name and version is name version Webpack v gt use strict const s JSON parse u test i console log The name and version is s u s i This is super optimized as we are using an import construct Most bundlers will treat import constructs as either side effect free or determine the tree shack ability by flags from the underlying package json Any way the code above is already good but what if we would have used require instead const name version require package json console log The name and version is name version Webpack v gt var e e gt use strict e exports JSON parse name test version description main index js scripts build webpack mode production test echo Error no test specified amp amp exit keywords author Florian Rappl license MIT dependencies webpack webpack cli r function s o var i r o if void i return i exports var n r o exports return e o n n exports s n exports gt const name e version r s console log The name and version is e r Now in this variant the whole output is not only unnecessary verbose but also contains potentially sensitive information such as the used dependencies and build commands Really not ideal What if we could just generate a module on the fly that will only export the properties name and version that we are interested in const name version require info codegen console log The name and version is name version In this case the info codegen looks like module exports function const name version require package json return export const name JSON stringify name export const version JSON stringify version This is just a standard normal Node js CommonJS module If we d run the exported function we get back a string with valid JavaScript code This is the module that Webpack will consider The imported module is just a definition to actually generate the module The process is shown below Now what does that give us Webpack v gt var e e o r gt use strict r r o r d o name gt t version gt n const t test n o function r t var n o t if void n return n exports var s o t exports return e t s s exports r s exports r d e o gt for var t in o r o o t amp amp r o e t amp amp Object defineProperty e t enumerable get o t r o e o gt Object prototype hasOwnProperty call e o r r e gt undefined typeof Symbol amp amp Symbol toStringTag amp amp Object defineProperty e Symbol toStringTag value Module Object defineProperty e esModule value gt const name e version o r console log The name and version is e o Surely as we are using some other JS module via require Webpack still introduces some overhead with all the definitions in here but overall the information is condensed to the format we d like to see The output gets even better using import in which case the introduced overhead can be just removed cleanly gt use strict console log The name and version is test Those gained few bytes are of course not the full spectrum of code generation benefits Even though we can already see some advantage Consider that you are not interested in name and version but rather a package identifier Originally you d have written import name version from package json const identifier name version console log The package identifier is identifier Resulting in the following code Webpack v gt use strict const e JSON parse u test i i e u e i console log The package identifier is i However using codegen you can spare the computation at runtime You just prepare everything as you want it to be index jsimport packageId from info codegen console log The package identifier is packageId info codegenmodule exports function const name version require package json return export const packageId JSON stringify name version With this the resulting code Webpack v looks like gt use strict console log The package identifier is test Not only smaller but also does not require any computation The information that can be pre computed is pre computed How Does It Work The beauty of this approach is that a module transformation has direct access not only to Node js but also to the module itself As such it can just require or evaluate the module in a sandbox Afterwards the exported function can be run to get back a string This string is the result of the code transformation The whole process works as shown in the following diagram In theory the string does not have to be JavaScript code It could also be the content of an asset file or something transpiling to JavaScript like TypeScript In practice however JavaScript makes the most sense Since many bundlers actually allow parallel transformations we should also try to make the API as asynchronous as possible A good step in this direction is to allow returning a Promise from the code transformer Using our previous example we could rewrite that to be info codegenconst readFile require fs promises module exports async function const content await readFile package json utf const name version JSON parse content return export const packageId JSON stringify name version The whole flow can be used to use asynchronous APIs for constructing modules dynamically Let s see an example in action Example Getting Asynchronous InfosLet s say we have a small static website that is gonna be built everyday periodic CI CD On build time an API is being called and the result is used to actually drive the build How would you construct such a thing Well surely one way is to have a shell script doing the download Then you either use the download assets directly in your code base essentially bundling it in or you already bring the asset in the desired form e g into some React code This way there would be less work at runtime later on While this is a suitable solution it is not the most elegant one nor is it the most robust one For instance what language do you use for the script file If its bash or PowerShell then the file might not run on the system of other developers Okay cool so you ve chosen JavaScript and that most work as the other tooling uses the same Well even then running this script and bundling are two separate commands Okay so you bring the script into the bundler somewhat But then how do you reference the output Another gitignore rule Okay so on first time use TypeScript will show errors Using a codegen file now allows you to bring this into your bundler pipeline including caching re evaluation and hot reloading Here s an example code App tsximport Pictures from pictures codegen export default gt lt gt lt div gt Some content lt div gt lt Pictures gt lt gt pictures codegenconst default axios require axios module exports async function const data await axios get const urls data thumbnailUrls slice return export default function Pictures return lt div gt urls map url gt lt img src JSON stringify url gt lt div gt The idea here is to generate everything necessary such that at runtime no additional work has to be done Example Building a Media LibraryThe previous example could also be used to make certain images media assets available in a much simpler form Usually in your bundler you ll need toimport MyImage from assets my image png lt img src MyImage gt But that is broken when you e g want to have something likeconst userAvatar user avatar const image images userAvatar lt img src image gt Now of course you can go the hard way and define images like thisimport Hulk from assets avatars hulk png import Ironman from assets avatars ironman png import Spiderman from assets avatars spiderman png const images hulk Hulk ironman Ironman Spiderman Spiderman but that is not only very verbose but also not very flexible A new avatar was added Well good luck remembering that you need to change the file above and change it on two places To simplify this Webpack actually supports require context but its rather limited and only available in Webpack A better more flexible alternative is to use codegen here import images from media codegen media codegenconst readdir require fs promises const resolve require path module exports async function const assets resolve process cwd src assets const avatarsDir resolve assets avatars const avatars await readdir avatarsDir const usedImports avatars filter a gt a endsWith png map a i gt import i from JSON stringify resolve avatarsDir a const images avatars filter a gt a endsWith png map a i gt JSON stringify a replace png i return usedImports join n export const images images join Importantly in the example above we generate a set of imports that just look identifiers like pretty much ensuring that there are no conflicts otherwise we d need to make sure to not only generate valid identifiers from the file name but also non conflicting ones However for the actual key names we still use the filename without the extension which may be problematic Therefore instead of making keys likeconst images foo bar we use it with a string to avoid issues with the name e g my asset png would be problematic otherwise const images foo bar foo bar Knowing such tricks concepts is quite handy when generating code reliably Example Automatically Generating Routing InformationOne feature that many web frameworks static site generators e g Next js Remix Astro have is file system based routing As such if you have a file system structure likeroot pages blogs index tsx first tsx second tsx internal first tsx other tsx index tsx about tsxUsing codegen you can make this work in any codebase Let s see how this could look like App tsximport BrowserRouter from react router dom import Routes from routes codegen export default gt lt BrowserRouter gt lt Routes gt lt BrowserRouter gt example pages blogs index tsxexport default function Page content routes codegenconst readdir stat require fs promises const resolve parse require path function makeSegment name sep return name normalize NFD replace u uf g toLowerCase trim replace a z g replace s g sep function makeElement path return React createElement React lazy gt import JSON stringify path async function makeRoutes baseDir baseRoute const routes const names await readdir baseDir for const name of names const path resolve baseDir name const info await stat path if info isDirectory const subRoutes await makeRoutes path baseRoute makeSegment name routes push subRoutes else if fn index tsx const route baseRoute const element makeElement path routes push lt Route path JSON stringify route element element gt else const fn parse path name const route baseRoute makeSegment fn const element makeElement path routes push lt Route path JSON stringify route element element gt return routes module exports async function const pages resolve process cwd pages const routes await makeRoutes pages return import as React from react import Route Routes from react router export default gt return lt Routes gt routes join n lt Routes gt There is quite a bit going on but rest assured most of the logic is to read out the directories and contained files then adding them to the routes and converting it all to a proper React representation Every route is lazy loaded to optimize the overall bundle size Yes you might even want to make this non static allow dynamic routing with parameters e g a file index id tsx would be a route to id but I left that out for simplicity All those examples have been mentioned just to give you some impression there is much more that you can do with it and presumably much better more elaborate than what I ve shown here Bundler SupportRight now support for codegen exists in the following bundlers Parcel v parcel plugin codegen Parcel v parcel transformer codegen esbuild esbuild codegen plugin Webpack v and v parcel codegen loader Vite vite plugin codegen Rollup rollup plugin codegen Examples for each bundler are included in their package descriptions The codegen content does not change the API remains the same across the different bundlers For instance to integrate support for codegen files in Webpack v you ll to first add the dependency Unit TestingNow that you have codegen imports in your project can you still use standard unit testing tools such as Jest for actually running tests Yes definitely There are multiple ways Just mock the import Similar to the idea with dedicated d ts files see recipes below you can introduce a mock explicitly e g using jest mock or implicitly e g having a satellite file js that would be preferred by the unit test runner Use a dedicated transformer Unfortunately a the time of writing Jest could either do only synchronous transformers or an asynchronous transformer if everything was available running in ESM format A synchronous transformer in Jest looks like import transformSync from babel core import SyncTransformer from jest transform const codegen SyncTransformer process string filename string const factory require filename const result factory call outDir global process cwd rootDir global process cwd const code transformSync result presets babel preset env modules commonjs return code getCacheKey string filename string let s never you can choose a different strategy here too e g considering the content of the file for having a proper hash const rnd Math random toString return filename rnd export default codegen Now you can set this up using the transformers section const config transform codegen resolve dirname codegen js IDE Support VS CodeThe support is actually quite simple just change the syntax to JavaScript js and you are good to go Some editors allow you to just configure a mapping e g to map codegen to use js or for codegen to be an alias of js In any case that s all you get for the moment In the future I think there might be dedicated support even to the point where the generated code could be inspected upfront and potential syntax errors or general issues could be detected before the bundler runs Recipes TypeScriptIf you want TypeScript support then all you need to do is to have a d ts file adjacent to your codegen file For instance in the initial example we came up with info codegen Adding a info codegen d ts next to the original codegen with the following content export const packageId string would be all that s needed for supporting TypeScript Now TypeScript knows that we can import the codegen file and actually knows what the content will be Variable OutputRight now a codegen file is still just a single module Therefore using import my codegen from two different modules will actually have no impact it s only evaluated once Is there a way to reuse one codegen module generating a different module depending on the context In Webpack there could be but in general not Therefore the codegen bundler plugin does not support this directly This is however not the end of that story What you can do is to generate additional physical modules and reference those As an example let s say you have two modules a ts and b ts and both would need the rendered content of some markdown document a md and b md respectively Now having two codegen files a codegen and b codegen would not be very nice after all both would have pretty much the same instructions Instead we d like to only have only a single one md codegen But we cannot parameterize it right So we cannot do a tsimport content from md codegen file a md and a tsimport content from md codegen file b md Sure as mentioned we can make this work in Webpack but generalizing it to other bundlers is difficult Instead you could maybe do something like a tsimport aContent from md codegen and b tsimport bContent from md codegen The trick is to use the generation dynamically e g to do something like const readDir readFile require fs promises const resolve require path const convertMarkdown require mdConverter module exports async function const dir resolve process cwd docs const docsFiles await readDir dir const mdFiles docsFiles filter m gt m endsWith md map f gt resolve dir f const result await Promise all mdFiles map convertMarkdown returns something like export const aContent lt div gt my markdown content lt div gt export const bContent lt div gt your markdown content lt div gt return result map name content gt export const name Content JSON stringify content join n Since the generated module is side effect free you ll get tree shaking essentially removing not used exports Therefore such a parameterization might be more expensive at build time but is not adding to the runtime cost Lazy LoadingChanging the previous problem statement to a question regarding runtime behavior we might end up with a demand for lazy loading That is we actually would want to write something like a tsimport md codegen file a md then default content gt As written beforehand we cannot parameterize such calls Also the tree shaking for such lazy imports works a bit different So we need a different strategy here The idea is to have the following a tsimport loadA from md codegen loadA then default content gt Now we only need to generate the lazy loading in the codegen file The idea is to have const readDir readFile require fs promises const resolve require path const upperFirst camelCase require lodash const convertMarkdown require mdConverter module exports async function const dir resolve process cwd docs const docsFiles await readDir dir const mdFiles docsFiles filter m gt m endsWith md map f gt resolve dir f const result await Promise all mdFiles map convertMarkdown returns something like export const loadA gt import temp md a ts export const loadB gt import temp md b ts return result map name path gt export const load upperFirst camelCase name gt import path join n In the code above we assume that convertMarkdown actually does not only give us the content or does no longer give us the content but actually also gives us a path to the content in a temporary file Now this file can be referenced from our generated module making it fully lazy loadable from the bundler s perspective ConclusionIn this post I ve went over a quite simple yet powerful plugin that is available for most bundlers and could be presumably easily added to missing ones Codegen It allows you to create a virtual module on the fly using the full Node js ecosystem Codegen gives you the bundler agnostic superpowers that are needed to build great applications today and in the future The only question is What will you build	2022-10-13 13:19:35

海外TECH	Engadget	The best tablets for 2022	https://www.engadget.com/best-tablets-150026056.html?src=rss	The best tablets for Following the release of the iPad Air and Samsung s Galaxy Tab S line earlier this spring there hasn t been a ton of movement in the tablet world At IFA Lenovo announced refreshed versions of the Tab P and P Pro featuring updated internals and even an inch OLED display with a Hz refresh rate on the Pro More recently Amazon launched revamped versions of its Fire HD tablets featuring new “Tap to Alexa functionality And while Amazon s e readers aren t typically thought of as tablets the new Kindle Scribe deserves some consideration thanks to the addition of an included pen and support for handwritten notes However people looking for a fancy new slate may want to hold off for now as rumors suggest that Apple is planning to release an updated version of the basic iPad sometime later this fall packing a USB C port instead of Lighting along with improved performance optional G connectivity and a slightly larger display Then looking further ahead Google has also announced that it s planning to release the upcoming Pixel Tablet sometime in Engadget s picksBest overall Apple iPad ProBest Android tablet Samsung Galaxy Tab SBest Windows tablet Microsoft Surface Pro Best budget tablet Apple inch iPadBest tablet for kids Amazon Fire HD Kids ProWhich OS is right for me Before you even start looking at specific devices consider how your new tablet will fit in with the gadgets you already own and how you plan to use it For example if everyone in your house uses Macs and iPhones it probably doesn t make a lot of sense to buy an Android tablet even if you ve been tempted by the massive inch screen on the new Galaxy Tab S Ultra This goes double for anyone with an extensive library of purchased videos and music that might be harder to access after switching platforms Another consideration is the kind of work you ll be doing That s because while all modern tablets are adept at browsing websites or playing games some operating systems like iPadOS and Windows are better designed to support multitasking and productivity than Android or even Chrome OS It s a similar situation for software because while most popular apps and games are available on both Apple s App Store and Google s Play Store more specialized enterprise software may only have proper support on desktop platforms like Windows or macOS What size screen should I get Trying to decide the size of your tablet is also related to the kind of work or play you intend to do Larger displays make it much easier to view two apps side by side with big screens also delivering a more immersive movie viewing experience But at the same time the larger the tablet the less likely you re going to want to move it around That means you re not only going to want to take stock of your workspace i e if you have a desk or instead plan to work from a couch or even your bed you re also going to want to think about how the device will fit into your everyday routine or commute if you have one Potential accessoriesFinally you ll want to consider any add ons or accessories you re planning to use which can range from detachable keyboards to things like external mics or a stylus The good news is that many tablets nowadays offer some kind of keyboard accessory which allows the device to function more like a in instead of simply being a content consumption device Some tablets also feature things like microSD card slots that support expandable storage or optional G or G connectivity which can be a real boon to frequent travelers And if you re planning to use the tablet mainly for work you might want to grab a USB hub for connecting all your favorite peripherals Best overall Apple iPad ProChris Velazco EngadgetPowered by the same M chips you get in Apple s MacBooks the iPad Pro is one of the fastest and most well built tablets you can buy today It s available in two sizes and inches and works with a range of accessories including the Apple Pencil and the extremely useful but pricey Magic Keyboard And thanks to their Hz ProMotion mini LED displays the iPad Pro s screen boasts strong brightness and fluid visuals regardless of whether you re watching a movie or creating a slideshow presentation Recent versions of iPadOS have also made Apple s most premium tablet a much more capable work device with the addition of new sidebars for quickly switching between apps a more powerful desktop like UI for Safari and various new toolbars throughout The main downside is that starting at for a base inch model with GB of storage Apple s iPad Pros aren t cheap and that s before you tack on any extras like cellular connectivity or a keyboard But considering there s a good chance a new iPad Pro is more powerful than your current laptop there isn t really anything you can throw at Apple s top of the line tablet it can t handle One final note is that if you like the iPad Pro but want something a bit more affordable there s also the fifth gen iPad Air You still get the same M chip Apple Pencil support and optional G connectivity And with a inch screen it s basically the same size as the smaller iPad Pro too The main difference is that the iPad Air s display isn t quite as bright and doesn t support a Hz refresh rate But if you re ok with that the fifth gen iPad Air is essentially an iPad Pro with a less fancy screen that starts at instead of Buy iPad Pro at Amazon starting at Best Android tablet Samsung Galaxy Tab SSam Rutherford EngadgetAvailable in three sizes an and a huge inch model Samsung s new Galaxy Tab S line has the right sized screen for practically any need And while Android typically isn t quite as accommodating to productivity as Windows or iPadOS Samsung s Dex mode offers a desktop like UI complete with multi window support and a taskbar for potent multitasking Samsung s mobile displays are also some of the best in the business with support for Hz refresh rates and vibrant colors from their OLED panels And unlike Samsung s flagship phone line the Galaxy Tab S still comes with microSD card support though sadly Samsung couldn t seem to find room for a dedicated headphone jack You even get a choice of three different covers a simple folio a keyboard cover and a keyboard cover with a built in touchpad so you can choose the right accessory for your needs Buy Galaxy Tab S at Samsung starting at Best Windows tablet Microsoft Surface Pro Sam Rutherford EngadgetWhile most people think of Microsoft s Surface Pro devices as a line of in s because they don t come with a keyboard you need to purchase it separately that technically makes them tablets But don t be fooled because thanks Windows and
