海外TECH	DEV Community	The Comprehensive Guide to Angular Performance Tuning	https://dev.to/tarungurang/the-comprehensive-guide-to-angular-performance-tuning-1l5n	The Comprehensive Guide to Angular Performance TuningIt s not uncommon to see Angular apps slow down over time Angular is a performant platform but if we don t know how to create performant Angular apps our apps will become slower as they evolve As a result any serious Angular developer must be aware of what makes an Angular app slow in order to prevent it from being slow in the first place Improving change detectionChange detection can be the most performance intensive part of Angular apps so it s important to understand how to render the templates efficiently so that we would just re rendering a component if it has new changes to display OnPush change detectionWhen an asynchronous event occurs in the app such as click XMLHttpRequest or setTimeout the default change detection behavior for components is to re render This can be a matter of concern because it will result in a lot of needless renderings of models that haven t been updated When an asynchronous event occurs in the app such as click XMLHttpRequest or setTimeout the default change detection behavior for components is to re render This can be a matter of concern because it will result in a lot of needless renderings of models that haven t been updated A new reference has been added to one of its input propertiesAn event originating from the component or one of its children such as a click on a component button Explicit shift detection runTo use this technique simply set the change detection strategy in the component s decorator as follows Component selector app todo list templateUrl todo list component html styleUrls todo list component scss changeDetection ChangeDetectionStrategy OnPush export class TodoListComponent implements OnInit Design for immutabilitySince we need a new reference given to a component s input to activate change detection with onPush we must ensure that all state changes are immutable to use this process If we re using Redux for state management we ll notice that each time the state changes we ll get a new instance which will cause change detection for onPush components when given to a component s inputs With this method we ll need container components to get data from the store as well as presentation components that can only communicate with other components via input and output The async pipe is the simplest way to provide store data to the template This will appear to have the data outside of an observable and will ensure that the stream is cleaned up when the object is automatically destroyed lt xml gt lt div class mx auto col gt lt h gt todo list translate lt h gt lt hr gt lt app cards list gt lt app cards list gt lt div gt lt hr gt lt app add todo gt lt app add todo gt lt xml gt Make onPush the default change detection strategyWhile creating new components with Angular CLI we can use schematics to render onPush the default changeDetection strategy In Angular simply add this to the schematic s property json is a type of data schematics schematics angular component styleext scss changeDetection OnPush Using pipes instead of methods in templatesWhen a component is re rendered methods in a prototype will be named Even with onPush change detection this means it will be activated any time the component or any of its children is interacted with click type If the methods perform intensive computations the app will become sluggish as it scales because it must recompute every time the part is accessed Read More Accessibility With AngularInstead we might use a pure pipe to ensure that we re just recalculating when the pipe s input shifts As we previously discussed async pipe is an example of a pure pipe When the observable emits a value it will recompute If we re dealing with pure functions we want to make sure we re just recomputing when the input changes A pure function is one that given the same input always returns the same result As a result if the input hasn t changed it s pointless to recompute the output public getDuedateTodayCount todoItems TODOItem console log Called getDuedateTodayCount return todoItems filter todo gt this isToday new Date todo dueDate length private isToday someDate const today new Date return someDate getDate today getDate amp amp someDate getMonth today getMonth amp amp someDate getFullYear today getFullYear With methodLet s look at what s happening when a template system is used instead of a pipe Consider the following procedure public getDuedateTodayCount todoItems TODOItem console log Called getDuedateTodayCount return todoItems filter todo gt this isToday new Date todo dueDate length private isToday someDate const today new Date return someDate getDate today getDate amp amp someDate getMonth today getMonth amp amp someDate getFullYear today getFullYear With pipeThis can be solved by changing the method to a pipe which is pure by default and will rerun the logic if the input changes We get the following results by building a new pipe and transferring the logic we used previously inside of it import Pipe PipeTransform from angular core import TODOItem from app shared models todo item Pipe name duedateTodayCount export class DuedateTodayCountPipe implements PipeTransform transform todoItems TODOItem args any any console log Called getDuedateTodayCount return todoItems filter todo gt this isToday new Date todo dueDate length private isToday someDate const today new Date return someDate getDate today getDate amp amp someDate getMonth today getMonth amp amp someDate getFullYear today getFullYear Cache values from pure pipes and functionsWe can also boost this by using pure pipes by remembering caching previous values so that we don t have to recompute if the pipe has already been run with the same input Pure pipes don t keep track of previous values instead they check to see if the input hasn t changed the relationship so they don t have to recalculate To do the previous value caching we ll need to combine it with something else The Lodash memorize method is a simple way to accomplish this Since the input is an array of objects this isn t very realistic in this situation If the pipe accepts a simple data type as input such as a number it may be advantageous to use this as a key to cache results and prevent re computation Using trackBy in ngForWhile using ngFor to update a list Angular can delete the entire list from the DOM and rebuild it because it has no way of verifying which object has been added or removed The trackBy function solves this by allowing us to give Angular a function to evaluate which item in the ngFor list has been modified or removed and then then re render it This is how the track by feature looks public trackByFn index item return item id For heavy computations Detach change detectionIn extreme cases we can only need to manually enable change detection for a few components That is if a component is instantiated s of times on the same page and re rendering each one is costly we can disable automatic change detection for the component entirely and only cause changes manually where they are needed We could detach change detection and only run this when the to do Item is set in the todoItem set property if we choose to do this for the todo items Component selector app todo item list row templateUrl todo item list row component html styleUrls todo item list row component scss

for a website to load is an important factor in today s user experience Every millisecond a user waits will result in a sales loss due to a higher bounce rate and a poor user experience so this is an area where we should focus our efforts Faster websites are rewarded by search engines so page load time has an effect on SEO We want to use Angular PWA caching lazy loading and bundling to improve page load time Cache static content using Angular PWASince the static content is already in the browser caching it will make our Angular app load faster This is easily accomplished with Angular PWA which uses service workers to store and present static content such as JavaScript CSS bundles images and static served files without requiring a server request Looking for Genuine Angular Development Company Enquire Today Cache HTTP calls using Angular PWAWe can easily set up caching rules for HTTP calls with Angular PWA to give our app a faster user experience without cluttering it with a lot of caching code we can either optimize for freshness or efficiency that is read the cache only if the HTTP call times out or check the cache first and then call the API only when the cache expires Lazy load routesLazy loading routes ensure that each function is packaged in its own bundle and that this bundle can be loaded only when it is needed To allow lazy loading simply build a child route file in a function like this const routes Routes path component TodoListCompletedComponent export const TodoListCompletedRoutes RouterModule forChild routes Import routes NgModule imports FormsModule CommonModule SharedModule TodoListCompletedRoutes declarations TodoListCompletedComponent export class TodoListCompletedModule using loadChildren in the root route const appRoutes Routes path rootPath component TodoListComponent pathMatch full path completedTodoPath loadChildren todo list completed todo list completed module TodoListCompletedModule export const appRouterModule RouterModule forRoot appRoutes Optimizing bundling and preloadingWe may choose to preload feature modules to speed up page load even further This way when we choose to make a lazily loaded feature module navigation is instant This can be accomplished by setting PreloadModules as the preloadingStrategy RouterModule forRoot routes preloadingStrategy PreloadAllModules All feature modules will be loaded when the page loads allowing us quicker page loading and instant navigation when we choose to load other feature modules This can be further optimized by using a custom preloading Strategy like the one shown here to load only a subset of the routes on app startup Server side rendering with Angular UniversalIt is recommended that server side rendering be used for Angular apps that contain indexed pages This ensures that the pages are entirely made by the server before being shown to the browser resulting in a faster page load This would necessitate the app not relying on any native DOM components and instead injecting document from the Angular providers for example Improving UXPerformance tuning is all about improving the bottleneck which is the part of the system that has the most impact on the user experience Often the alternative is simply to approach behavior with more optimism resulting in less waiting for the customer Optimistic updatesOptimistic changes occur when a change is expressed in the user interface before being saved on the server The user would have a snappier native like experience as a result of this As a result in the event that the server fails to save the changes we must roll back the state Strongbrew has written a post on how to do this in a generic way making positive changes simple to implement in our code How should we prioritize performance tuning Start with the low hanging fruit onPush lazy loading and PWA and then figure out where our system s output bottlenecks are Any enhancement that does not address the bottleneck is a mirage as it will not enhance the app s user experience Detaching the change detection is a tuning technique that can be used only if we have a particular issue with a component s change detection affecting output ConclusionIn this blog we have learned how to tune the output of our Angular app in this article Change detection page load and UX enhancements were some of the performance tuning categories we looked at Any change in a system should start with identifying bottlenecks and attempting to solve them using one of the methods described in this article	2021-11-23 06:07:33
海外TECH	DEV Community	With No Code Builders, Why Should Clients Hire a Developer?	https://dev.to/study_web_dev/with-no-code-builders-why-should-clients-hire-a-developer-53ip	With No Code Builders Why Should Clients Hire a Developer With the advent of tools that make building an e commerce site or basic portfolio website simpler than ever many developers are starting to wonder if this serves as a bad omen for things to come…If any client can simply open up an account on a no code builder drag and drop a few components until they re happy with the design click Publish and call it a day how is there possibly any hope for developers and web designers Unless you re just getting started as a developer you ve probably heard a similar version of this doom and gloom argument before but worry not my friend there s more than a glimmer of hope TLDR No code builders should be seen as an opportunity not a threat In this article I m going to explore exactly what sort of no code builders are out there the mistaken threat they pose to developers and the actual benefit of hiring a developer which you can use to build up your confidence to bolster your proposal proposition success I tweeted this last year give it a read to get an overview Kyle Prinsloo study web dev My two cents on “Why would a client want to pay for a website when they can just do it themselves for free with platforms like Wix Shopify WebFlow WordPress Squarespace etc Here s my answer in a thread ️ AM Sep What are No Code Builders No code builders are tools on the web that make building websites e commerce stores and even full blown applications possible without writing any code Low code builders are similar but can be ever so slightly more technical In reality no code builders are sometimes confused with low code builders where only a very little amount of code is needed when building out the site or app There is a huge variety of no code and low code builders out there today which could give you a new or even more experienced developer the impression that your job is being acutely challenged by smart software Webflow for example claims to be the modern way to build for the web where users of the tool can build production ready experiences without coding On Webflow you re able to design in the browser build a site connect it to a CMS and host it all without writing a single line of code Even the Webflow site itself is built using Webflow which brings a tear to my eye but in a good way Webflow is just one of these site building tools You may have heard of others like Wix Squarespace or Weebly They re all very similar tools but essentially they do what Webflow allows you to do although all of them offer a slightly worse experience in comparison with Webflow All of these mentioned builders normally come with pre packaged designs that allow you to simply select a design replace the placeholder text with yours and click Publish There are some caveats to this and they re bigger than you may expect…But more on that later Moving on from site builders there are plenty of other no code builders out there Shopify is another tool you may be familiar with especially if you ve worked with clients that require e commerce solutions Shopify offers businesses the means to construct a fully working online store without the need for a custom coded solution And then there is WordPress No talk of no code builders would be complete without mentioning probably the world s most famous content management system It s estimated that over million sites will use it today WordPress Why No Code Builders Won t Replace DevelopersNo code builders are all over the Internet these days and are being used by millions of people but does this mean that they are replacing developers Not for now no While these tools allow for sites and apps to be built much faster than what it would take a developer to hand code them these tools are still quite useless in the hands of someone who doesn t know what they are doing What often happens is that someone with a business idea let s call that someone Jim will see the multitude of ads for no code tools they have really high marketing budgets notice how simple it appears to design build and host a website and is then fooled into thinking that he can do something just as good Jim will then purchase a subscription to a no code tool like Wix it s free but only to a very limited extent and set about designing and building a site After several hours or days Jim has put together a site that to his eye looks great and is a sure fire way of propelling his business to success Except that well it is an objectively bad website in terms of its design and usability It takes Jim a few embarrassing conversations with a few friends and colleagues to realize that his site is not as good as he initially thought and that maybe it s better if he turned to a professional to sand the rough edges of his site or even redo it entirely Jim then approaches a developer or designer for the work who then charges a fair wage for the work done At the end of the day Jim possesses a Wix website that looks pretty good but now he has spent double or triple his budget and wasted precious time in getting up a site that can achieve his business goals Many freelancers know this fake story actually happens where they have to fix a lot of bad client websites they made themselves That s the troubling thing about many of these no code tools Clients often start off thinking they know what they re doing thanks to the if I can do it you can do it nature of these no code builder advertising campaigns At the end of the day there are quite a few big trade offs when a client chooses a no code builder over a developer The first mistake however is thinking that there should be a choice between a developer and a no code builder If there s one thing you takeaway from this remember this You will always get people who want to cut their own lawn and you will always get people who pay others to cut it for them Don t worry about those who want to cut their own lawn The Positive Sum Game of Developers amp No Code BuildersDevelopers only write code At least that s what everyone thinks In reality developers provide solutions to problems How they provide these solutions have changed with time But at the end of the day developers are hired to solve technical problems and provide tangible value to a client or company That s the core of what developers do Developers have for a long time tended towards snobbishness In particular many have looked down at abstracted programming languages and environments as lesser or illegitimate Companies and clients that require custom software solutions still need developers for specific tasks You don t see Amazon turning to Shopify to run its latest brand merchandise shop Likewise clients who need custom solutions will hire developers who understand software Those companies that will rather use a no code builder probably did not have developers working for them full time anyways The thing is these builders don t facilitate the kind of work that developers do in the first place More abstraction in the case of software tools and solutions does not replace developers Rather it equips them to complete tasks that would otherwise be unnecessarily time consuming This allows higher productivity which is better for the company or client in question What are the Potential Issues of No Code Building Apps It is undeniable that many businesses and companies are attracted to the enticing benefits of no code building platforms but you should bear in mind that there are always some cons to something such as the following Limited features and templatesIf your business requires a more distinctive procedure or strategy the no code option may not be a good choice No code development platforms give multiple templates and components that may be modified to fulfill a set of use cases when it comes to building up the various elements of an application SecuritySince you re developing an app or a website from another app or website there s no guarantee that you re safe from any breach or major issues that the no code platform can encounter You won t even have control over the provider s technology stack when you use no code If the provider s internal security is breached you and your project would be exposed including all of the money and time you put into developing it would be wasted OwnershipYou need to rely on the original vendor to ensure that your application is properly maintained in the future If you have a contract with no code builders it might be hard and costly for you to switch providers if needed The Benefits of Hiring a DeveloperDevelopers are professionals They understand the intricacies and nuances of the web that allow them to know when a website or application is not working as it should This is valuable in and of itself but the real value of a developer is in his or her ability to prevent problems before they even arise and this is where many clients who don t use a developer get caught out Developers also often bring varied skill sets to the table You d be hard pressed these days to find a developer who is also not well versed in at least one other complementary skill such as design digital marketing content writing or SEO Hiring a developer is not the same as getting a subscription for a new software tool to get a job done A developer represents expertise that understands the holistic picture It is this key point that results in vastly differing results when a no code tool is put in the hands of a developer versus it being used by the client himself Developers are experts Clients with unknown tools in their hands are not What clients get by hiring developers are people who can bridge the gap between software capabilities and the business requirements of the client How a developer achieves this is often abstracted away from the client who really only cares for the end product and whether it works and looks as expected Conclusion You re The Asset Not The Tool You UseNo code tools may initially serve as a source of anxiety for developers and their sense of work security but digging a little deeper reveals a different story Technology has evolved and continues to do so at a rapid pace Those who maintain their value in the workforce are those who remain relevant A developer who uses a low or no code tool to achieve a specific client requirement is just as relevant as a developer who hand codes the solution The key differentiator here is time Everyone values their own time the most Save your client time and you ll set yourself apart from the developers looking to remain in their old ways This can be a nuanced argument but a common developer vs no code tool story can be boiled down to this A client needs an expert to build his or her product They will realize this at some point if they go down the journey of building their product themselves It s up to you the developer to remain vigilant in upgrading your skillset and confident in the business and technical acumen that you can offer clients Do this and you ll forever be a sought after professional developer who adds value And remember you ll always get the guy who wants to cut his own lawn but you ll always get the other guy who pays someone to do it for him Same principle applies to web development design freelancing etc What do you think If you have anything to add or say about no code builders let me know Until next time
