海外TECH	DEV Community	Explained: Why headless commerce helps SEO and page speed	https://dev.to/medusajs/explained-why-headless-commerce-helps-seo-and-page-speed-nm5	Explained Why headless commerce helps SEO and page speedYet another one of those SEO Page performance articles I myself have probably read of these by now and to me they always end up being either a overly technically detailed or b some superficial marketing gimmick that in itself is build for SEO purposes With this article I tried to put some words to the performance benefits of headless commerce in the same vein as I would when I talk to ecommerce managers straight to the point but not too fluffy at least that was the aim Disclaimer I will focus the arguments from the points of an open source headless solution which is different from proprietary solutions offered by Commercetools Commerce js etc Why page speed and SEO Page speed and SEO improvements have for many merchants been among the key reasons to opt for a headless commerce platform In this article we will explain how a headless setup can serve as a strong technical foundation to improve performance on these parameters So why are page speed and SEO so important in ecommerce If we start with page speed studies have shown that if a webshop has a load time of more than seconds then of the visitors abandon the site On top of that a one second delay leads to a reduction in conversion Not just this page speed also impacts your website s SEO performance making it a potential ranking factor in Google SERP Search Engine Result Pages Google and other search engines make your brand visible and drive traffic but if Google does not know you there s no way that your customers will Online searches lead to almost of the total ecommerce traffic but only the top Google search results get of all the traffic As the need for speed and enhanced SEO performance increases in importance developers need to put focus on optimizing ecommerce sites for these parameters The good part is that developers now have the right technology at their disposal with many headless commerce platforms emerging and these are now becoming more widely accessible with open source solutions such as Medusa How headless commerce workBefore going into the details of how headless commerce enables optimized performance it is important to understand how it works At its core headless commerce refers to the decoupling of the frontend the visual storefront and the backend the engine handling orders customer data etc This means that your storefront can run separately without impacting the backend like logistics inventory product details etc This architecture allows businesses to take full control of the user experience with the storefront while configuring a fully customized backend to handle their needs From a shopping cart to the payment gateway all functional elements can work as a microservice and be programmatically managed while API supports the transmission and management of data Headless commerce breaks the monotony of the monolithic structures that tied both systems together in one which is often seen with traditional platforms like Shopify This gives some ease to setting it up bit it also makes the solutions rigid rather than flexible If you want to know more about the overall impact a headless setup can have on your ecommerce store then check out our old article on what ecommerce managers thought to be the key benefits of a headless architecture How page speed amp SEO is improved through headless commerceEven though SEO can be a moving target with the ever changing algorithms and updates there are a few parameters that almost certainly will help improve your rankings We will explore four of the key reasons below Using CDNs amp optimized servers for deploymentA Content Delivery Network like Netlify or Cloudflare enables you to distribute your content across a wide network of servers globally This network of servers hosts your website content and pulls it from the server which is closest to the visitor in order to reduce load time as data doesn t have to transit as far When a user then loads a web page it will be the closest CDN that sends a catched version of the web page s content to the user s browser This can have significant impact on page load time in some instances CDNs have been able to reduce page load time by as much as When using out of the box e commerce platforms e g Shopify you most often depend on the server they use as the hosting option for your commerce platform Although this might look like an easy deployment option it is not optimal for your page speed to for instance use a US based server when operating in Europe With a headless solution you can use optimized servers for deployment to improve page delivery speed to the end user Use an SSGA static site generator SSG helps you improve page load speed An SSG lets you create static web pages consisting of HTML CSS and frontend JS that can be hosted directly on a CDN Whereas traditional website generators only generate a page when it is requested by the user static pages are generated ahead of time and do not need to be generated on the server when the user accesses it One example of the impact of implementing an SSG can be seen at QueryClick com a small BB site which witnessed a load time reduction up to after the deployment of a SSG With newer SSG frameworks like Gatsby and Next js it has become significantly easier to build static sites that they use of popular technologies like ReactJS GraphQL Webpack etc and makes it easier for developers to jump in without much of a learning curve Plus these frameworks do data fetching such as data sourcing from local files This data is then used to generate static HTML CSS and JavaScript files Fewer Plugins To Improve Load TimeMonolithic solutions are built for simplicity often obtained through templated solutions Although templates offer a good starting point they often end up having more deteriorating long term consequences on page performance due to a lack of flexibility and customization options What happens for most webshop owners is that they end up wanting a more customized setup than what they set out to do as their business needs evolve over time When starting from a templated design the only way to solve this issue is by adding new plugins that solve customization issues at hand However most of these plugins especially on the frontend require a huge amount of processing power slowing down the load time of the site The problem is often described as “dead by plugins and can be avoided using open source solutions and headless architecture to build custom functionality into the core project instead of relying on outside solutions that might in turn negatively impact performance Full control of page structure and contentUsing a headless architecture likewise solves many of the common issues with the lack of page structure and content control that content specialists are often vocal about with monolithic solutions Websites that use monolithic structures like Shopify generally experience SEO hurdles due to the predetermined sites structure which makes it hard to fully optimize the website setup What happens with a monolithic solution is that the pages you create on your website will have a ranking structure you can t make changes to A common Shopify problem is that with each new category comes multiple URLs Buffer com is one such website that faces this issue Because of multiple paths that lead to the same page duplicate product pages are produced with the same content but a different URL See example below where each of these URLs leads to one page only e g These pages are almost exact duplicates All of this drastically impacts the ranking on SERP since search engines aren t capable to infer which duplicate page to rank therefore giving preference to other web pages Using a headless commerce platform enables you to control the way your content is rendered as content lives on a separate server and can be structured independently for an optimal page structure Optimize page speed and SEO with MedusaOkay a bit of commercializing in the end No seriously headless commerce presents some easy to grasp benefits in the form of page speed and SEO performance The problem has been that small to midsized merchants would not consider these solutions due to the excessive costs associated with them That is why Medusa made it a key priority to Lower the bar for when developers and businesses can shift to a headless commerce platformThis is done by Open sourcing the solution to enable merchants to start for free compared to competing platforms starting at USD yearCreating a setup that is easy to use and extend even as a smaller merchant with limited developer resourcesMaking a suite of plugins quick starters and migration tools freely available to make it easy to get up and runningWith a lower bar for entering into the world of headless commerce Medusa aims to make the benefits accessible to merchants of all sizes in the future If you are interested to hear more feel free to check out

海外TECH	DEV Community	Understanding ViewChild and ViewChildren in Angular	https://dev.to/this-is-angular/understanding-viewchild-and-viewchildren-in-angular-1aep	Understanding ViewChild and ViewChildren in AngularToday we will learn a very important and powerful concept in Angular the ViewChild and ViewChildrenOn a high level ViewChild and ViewChildren both are property decorators With this decorators we can ️⃣Access an element present in the same template html of the component ️⃣Access the child componentSo we can say it s used to access elements present in the template The Syntax ViewChild selector read readValue static staticValue propertyNameI will touch upon the syntax as and when we need them So what we will achieve at the end of this demo We will create a counter component It will have a counter initialized to There will be two methods one to increase the counter by x amount and the other to reduce by x amount The component methods will be accessed or you can say called from the parent only Lets setup our playground first Lets create a component called my counter and make it a child component of app component If you are wondering how to make a child component Please have a look at this post before moving ahead Once we create the component lets open the my counter component ts file and add the below code counter constructor ngOnInit void increaseCounter x number this counter x decreaseCounter x number this counter x And in the corresponding template file lt p gt Counter Value counter lt p gt Now lets move to the app component ts file and the following code increaseCounter x number decreaseCounter x number We will add the method body soon And in the corresponding template the following code lt input click increaseCounter type button value Add by gt lt input click decreaseCounter type button value Subtract by gt Output till now And the button does nothing But it will do Now lets come to the real part We will see ViewChild first So lets add a property in app component counterReference The property counterReference will be holding a reference of the Counter component So we will assign counterReference as MyCounterComponent and also decorate it with ViewChild So the final code will become ViewChild MyCounterComponent counterReference as MyCounterComponent The viewChild accepts few parameters The first parameter is the Component which you want to select or get the reference in this case You can also query using a templateReference which I will show soon Now lets complete the functions which we kept empty increaseCounter x number this counterReference increaseCounter decreaseCounter x number this counterReference decreaseCounter Here in the above code you can see with the property counterReference decorated with ViewChild we can access the child component MyCounterComponent methods When you click any of the button you will see the Counter value is getting changed So from the parent you can access the child methods Cool right Now the next variation as I said earlier using template reference Example of a template reference lt div myTemplateRef gt lt div gt lt app my counter componentTemplateRef gt lt app my counter gt Observe the pound symbol It is a variable to reference the DOM within a template Here myTemplateRef or componentTemplateRef is the template reference Lets add few more lines of code to see how it works Add the below lines of code in component ts file ViewChild myTemplateRef myTemplateRef ViewChild componentTemplateRef componentTemplateRef And in the corresponding template file lt div myTemplateRef gt lt div gt lt app my counter componentTemplateRef gt lt app my counter gt Now a very important piece of information You might have seen a method that gets generated when you create a component using CLI the ngOnInit This is a Angular lifecycle hook method I will talk about the Lifecycle Hooks in details in the upcoming post Similar to this method there is another life cycle hook method called ngAfterViewInit So when ever the template view initialization is complete or I can say view is ready the ngAfterViewInit method is called and all the properties decorated with viewChild are ready to use Before that they are uninitialized undefined In the ngOnInit the properties would look like below And in the ngAfterViewInit the properties would look like In summary a quick pictorial representation static By default the value of static is false The true value is used to support creating embedded view on the runtime When I will write about creating dynamic component again I will talk about static true Now coming to ViewChildren It is very similar to ViewChild except it provides a collection of matching references as a QueryList of items QueryList Its an unmodifiable list of items that Angular keeps track of and up to date when the state of the application changes There are few properties and methods of QueryListfirst gets the first item in the list last gets the last item in the list length gets the length of the items changes An observable It emits a new value whenever the Angular adds removes or moves the child elements JavaScript array methods like map filter find forEach etc are also supported by the QueryListNow the example You have three entries of the same component lt app my counter gt lt app my counter gt lt app my counter gt lt app my counter gt lt app my counter gt lt app my counter gt And you want to get hold of all the items ViewChildren is the best choice ViewChildren MyCounterComponent viewChildrenRef QueryList lt MyCounterComponent gt undefined Here using ViewChildren you can get access to all the matching selector You can loop through them and perform any operation you need to That s all for now Hope you enjoyed reading the postIf you liked it please like ️share comment Coming up more topics on Angular So stay tuned I will be tweeting more on Angular JavaScript TypeScript CSS tips and tricks So hope to see you there too Cheers Happy Coding	2022-01-21 12:12:08
