海外TECH	DEV Community	How to Make any Website Shoppable with Commerce Layer	https://dev.to/bolajiayodeji/how-to-make-any-website-shoppable-with-commerce-layer-3j0j	How to Make any Website Shoppable with Commerce LayerDigital commerce has changed and there is an increasing demand for faster and highly efficient solutions across multiple interaction channels The rise of headless commerce allows for more creative flexibility better performance and efficient software development Developers can now make any website shoppable serve customers on several platforms using the same code and content with no interruption to the customer journey using tools like Commerce Layer As an API first and stack agnostic platform Commerce Layer provides commerce APIs for inventory orders shopping carts prices promotions shipments customers and more Ecommerce businesses can integrate Commerce Layer to manage the transactional part of their sales channel alongside any architecture or tool of their choice be it WordPress Drupal Headless anything and serve their storefront on multiple presentation layers desktop mobile wearable devices IoT etc In this article you ll practice the basics of headless commerce by building a simple ecommerce product page with static content HTML and TailwindCSS as seen in the screenshot below We will then integrate Commerce Layer to make the website shoppable using the Drop in Javascript library and deploy the application to the cloud The Drop in library is a minimal way to get started with headless commerce and Commerce Layer but if you re building for your business you can opt for a deeper integration using the Commerce Layer SDK PrerequisitesSome HTML CSS Javascript and command line knowledge A general understanding of how APIs work An IDE and Git installed What is Commerce Layer Commerce Layer is a multi market commerce API and order management system that lets you add global shopping capabilities to any website mobile app chatbot wearable device or IoT device with ease You can compose your stack with the best of breed tools you want and make any experience shoppable anywhere through a blazing fast enterprise grade and secure API The diagram below shows the relationships in an example stack for building a solid ecommerce web application using Commerce Layer and other composable tools Getting StartedLet s start by building the static website with HTML and TailwindCSS all in a single index html file We will then integrate Commerce Layer using the Dropin library ️⃣Create the required filesCreate a new folder somewhere on your computer Create an index html file in the root directory Create a css directory with a custom css file in it ️⃣Get your API CredentialsYou can create an account to get access to and integrate with Commerce Layer APIs following the steps below Create a free developer account here If you already have an account kindly skip to Step Upon successful sign up skip the onboarding tutorial for the purposes of this article we ll set up and seed the organization manually through the CLI shortly Create a new organization for your business In the Commerce Layer dashboard click on the Sales channels tab and create an application with the name Website Upon successful creation you ll get a CLIENT ID and BASE ENDPOINT Kindly remember to save that as we ll use it to interact with our application later In the Commerce Layer dashboard click on the Integrations tab and create an application with the name CLI and role Admin Upon successful creation you ll get a CLIENT ID CLIENT SECRET and BASE ENDPOINT Kindly remember to save that as we ll use it to interact with the CLI later ️⃣Setup Commerce Layer CLIThe Commerce Layer CLI helps you to manage your Commerce Layer applications right from the terminal Installing the CLI provides access to the commercelayer command You can set it up using the following steps Install the CLI using your favorite package manager npmnpm install g commercelayer cli yarnyarn global add commercelayer cliLog into your application via the CLI using the previously created CLI credentials like so commercelayer applications login o lt organizationSlug gt i lt clientId gt s lt clientSecret gt a lt applicationAlias gt You will do the above for both applications sales channel and integration The login command adds the application and sets it as the current one in session You should log into the sales channel first and then the integration This way you ll have the integration as the current app which is required by the seeder ️⃣Seed organization with test dataAs we mentioned earlier you can seed your organization with a merchant a set of markets products SKUs related prices shipping methods inventory etc via the CLI Install the seeder plugin using the command below commercelayer plugins install seederSeed your organization using the command below commercelayer seedThe CLI will use Commerce Layer s default seed data to populate your organization with a set of products SKUs related prices and inventory information Build the Static Product PageNow let s build our product page in a single index html file which will contain the markup for product details prices available variants available quantity item availability shopping bag and checkout You can find the full code on GitHub In this tutorial we will only highlight the important HTML elements and related data attributes we need for dynamic data We will replace all style classes with the dummy content so you can focus on the utility classes required to interact with the Drop in library We will be using some data attributes to store extra information that doesn t have any visual representation like data sku code to store the SKU code of an item or data add to bag id to add a selected variant to the shopping bag when the Add to bag button is clicked The Dropin library requires some data attributes to add dynamic data to a static web page With this mechanism you re building ecommerce with almost no code required just HTML tags Now let s proceed ️⃣Create Static ContentYou should add some content to the page such as product names descriptions reviews and images and more This content can be created with any CMS and rendered with any language For this tutorial we re using just plain HTML lt DOCTYPE html gt lt html gt lt head gt lt Static

order associated with some line items If there are any errors we display them in the availability message container The customer can then decide to check out the order Checkout FunctionalityThe Drop in library uses the Commerce Layer checkout application to provide a PCI compliant PSD compliant and production ready checkout flow powered by Commerce Layer APIs The orders API will return the checkout URL using the format lt your organization slug gt checkout commercelayer app order id accessToken lt token gt The Drop in library will then automatically pass that URL to the checkout button with class clayer shopping bag checkout alongside the order ID and required access token When you click on the checkout button you will be redirected to the checkout application Upon successful checkout the order will be sent to and can be managed in the orders management system OMS in the Commerce Layer dashboard So cool right Deploying the Final ProjectNow let s push our project to GitHub

海外TECH	DEV Community	Strategy Design Pattern in Go	https://dev.to/im_rsawra/strategy-design-pattern-in-go-77e	Strategy Design Pattern in GoAccording to Wikipedia The strategy pattern also known as the policy pattern is a behavioral software design pattern that enables selecting an algorithm at runtime Instead of implementing a single algorithm directly code receives run time instructions as to which in a family of algorithms to useThe strategy design pattern comes under the behavioural pattern Strategy design pattern turns a set of behaviors strategies into objects and makes them interchangable inside original context object We create objects which represent various strategies and a context object original object which holds a reference to a strategy object and delegates it executing the behaviour In order to change the context object perform its work other objects may replace the currently linked strategy object with another one ExampleSuppose we are building an in memory cache Since the size of an im memory cache is limited whenever it reaches its maximum size alloted some enteries have to be removed in order to free up the space This task can happen via several algorithms First In First Out FIFO remove an entry from in memory cache that was created first Least Recently Used LRU remove an entry from in memory cache that has been used least recentlyLeast Frequently Used LFU remove an entry from in memory cache that has been used least frequentlyThe main idea is to decouple the cache object class from these algorithms strategies so that we can change the algorithm at runtime Also the original cache class should not change when a new algorithm is being added in the future This is where Strategy Pattern comes into play It basically suggests to create the family of algorithms and each algorithm having its own class Each of these classes implement the same interface and this way the algorithm becomes interchangable within the family Lets say the common interface name is evictionAlgoevictionAlgo go Strategy Interfacefifo go Strategylru go Strategylfu go Strategycache go ContextHere as you can see the original context object cache holds a reference to a strategy interface evictionAlgo main go Client CodeOutput Evicting by lfu strtegyEvicting by lru strtegyEvicting by fifo strtegy	2022-02-16 13:17:40

海外TECH	DEV Community	Semantic HTML explained and how to use it	https://dev.to/diballesteros/semantic-html-explained-and-how-to-use-it-35jm	Semantic HTML explained and how to use it What is Semantic HTML What are Semantic HTML elements When looking at one it seems like any other HTML tag however its meaning and intended use are clearer to the browser interpreting the HTML code and possibly the developer reading the code It may be common to see most HTML split up with either divs or spans However this can be very difficult to understand the intent behind the divs But in the case of semantic HTML elements we can be more explicit when differentiating between all the parts of the page using tags such as What does this look like The following is a brief visual example of what normal HTML looks like compared to Semantic HTML Image from On the left we are only using divs to separate the structure of our web page This is very uninformative and has several downsides On the right we have a much better visualization of how the page is actually laid out and what each part represents This results in a more organic layout with our header ー content ー footer BenefitsSo to summarize the benefits we receive Increased clarity on the structure of the webpageSEO benefits ー web crawlers have an easier time parsing the website and understanding the contentImproved DX Developer experience But how do I use it Here are some examples of how to use semantic tags note that there are about semantic elements available so this article won t cover them all Main contentFor most web pages you can instantly start getting some benefits from using more semantic tags For example you can being by splitting up the page into three sections using the header main and footer tags Where in this case the main would be the meat of your page Some things to consider about the header tag This should contain some of the  ー  tags Only using one tag Your logo or icon and any authorship information The footer usually contains but is not limited to copyright information sitemaps or any other contact information lt header gt This is a header lt header gt lt main gt This is the main content lt main gt lt footer gt Footer lt footer gt SectionsDividing the sections of the page is usually done with the section and article tags Some say that this can be interchanged but there are some clear differences to take into consideration The article tag should contain independent content that does not require any other context Whilst the section tag is explicitly tied to the content of the page but is further divided into its respective subsections lt article gt This is self contained content lt article gt lt main gt lt section gt Related Content lt section gt lt section gt Related Content lt section gt lt main gt ImagesA figure tag is a great option for an image picture This should typically be used for more self contained content One of the added benefits of this tag is that it can be used in conjunction with another tag figcaption to add a small caption at the foot of the image The figure tag contains both the img and figcaption tags to make it clear to the browser that these two are related to one another A nav tag should contain within navigation links that either navigate to other sections of the same page or other pages These can either be used for navbars menus tables of contents or anything else involving navigation Here is a small example Not the prettiest but the main focus are the tags If you want any more explanations regarding semantic HTML let me know in the comments below More content at Relatable Code If you liked this feel free to connect with me on LinkedIn or Twitter Originally published at on February	2022-02-16 13:06:09

海外TECH	DEV Community	Side effects	https://dev.to/ruizb/side-effects-21fc	Side effects Table of contentsIntroductionHow to deal with side effectsChaining side effects IntroductionInitially I wanted to talk about function purity and referential transparency at this point of the series However when preparing the article I used a significant amount of references to the term side effect This is why I chose to introduce side effects before talking about function purity Both concepts are related to one another but they deserve their separate article So what is a side effect A side effect is an interaction with the outside world Now you might be wondering what is the outside world then It is anything that is not part of the domain layer of the software Here are some examples of these types of interactions Reading a file and or writing to a fileMaking a network request calling an API downloading a file Reading from a global state e g global variable a parameter from the parent s closure Throwing intercepting an exceptionFor web applications using DOM objects and methodsLogging messages to the consoleThe domain layer contains all the models logic and rules of the domain If you are familiar with the hexagonal architecture also known as ports and adapters architecture then this layer is at the very center of the diagram Generally speaking all the functions from the domain layer can be tested with unit tests as there are no side effects This is the only layer that is pure all the others encompassing it have side effects In functional programs functions have to be pure i e side effect free Why Because side effects are not deterministic and they are hard to reason about When we want to validate that a function works as expected we have to be able to understand it and use automated tests Introducing non determinism and external references into the function makes it hard to understand it simply and test its behavior That being said a program that has no side effects is not very useful We need interactions with the outside world such as getting input from a user writing to a database or displaying something to the screen So on the one hand side effects are bad but on the other hand they are mandatory to build useful programs What can we do about it How to deal with side effectsOne particularity of a side effect is that it just happens In our imperative programs a side effect does not return anything In other words we cannot store it in a variable or pass it as a parameter of a function We can easily identify functions that perform side effects as they are the ones that do not return any value For example function trustMeNoSideEffectHere void This function s name is misleading as its return type does not match its name The void type indicates that this function does not return any value Therefore if it does not compute any value it is either useless or performs at least a side effect Of course we can still have functions that return a value but also perform side effects function trustMeNoSideEffectHere number let n window foo bar mutating the global state side effect return n In an imperative program with no defined rules regarding side effects we must read the definition of the function to understand what it does thus losing the type based reasoning benefit Furthermore the moment we call the trustMeNoSideEffectHere function the side effect immediately happens We have to make sure the environment is ready right before calling the function otherwise we are exposed to undesired behaviors In functional programs since functions are pure i e no side effects they must return a value otherwise they are pretty much useless In addition determinism is a key aspect of functional programming We cannot allow a function to trigger a side effect just by calling it As developers we want to control when the side effect happens remember side effects must happen at some point otherwise the program is pointless How can we make the trustMeNoSideEffectHere function pure and control when the side effect i e global state mutation happens One way of doing it would be to wrap some parts of this function in another function making it lazy function trustMeNoSideEffectHere gt number let n return gt window foo bar mutating the global state side effect return n What happens when we call trustMeNoSideEffectHere We get a value of type gt number that we can store in a variable const res gt number trustMeNoSideEffectHere Did anything happen No The global state has not been mutated yet since we have not called res yet Though we changed the definition of trustMeNoSideEffectHere to make it pure it always returns the same value a function Granted if we call the function twice we will get different references for the inner function trustMeNoSideEffectHere trustMeNoSideEffectHere would be false So technically we do not return the same value Still since functions equality is a complex topic let us assume that the values are equivalent here and move on Now that the function is deterministic we can write a unit test although it is not very useful in this case expect trustMeNoSideEffectHere to be a function Imagine you are testing the launchNuclearWarheads function It is pretty nice to make sure that calling launchNuclearWarheads does not do anything and that it requires an extra step to actually end life on Earth The moment we are calling res the side effect will happen thus propagating the non determinism to the parent functions At this point it is not possible to write unit tests for the main serviceA and serviceB functions What can we do to make these functions deterministic We can apply the same strategy as before returning functions that wrap the side effect cf the blue wrapping function on the following picture We managed to make the serviceA and serviceB functions side effect free Only the main function is impure and performs side effects which is convenient now we know where all the side effects actually happen in the program Chaining side effectsWhat happens when we want to chain side effects For example First we want to ask for the user s nameThen we want to perform some API call with the user s name e g to retrieve some information regarding its origin Finally we want to display the result on the screenAgain we can use the same technique make any side effect lazy by wrapping it inside a function here we are assuming the code is run in a browser function askForUserName gt string return gt prompt What is your name function getUserNameOrigin userName string gt Promise lt string gt const sanitizedName userName toLowerCase return gt fetch get origin sanitizedName then res gt res json then res gt res userNameOriginText function displayResult text string gt void return gt document getElementById origin text innerText text function originNameService gt Promise lt void gt return gt const lazyUserName askForUserName const lazyGetUserNameOrigin getUserNameOrigin lazyUserName return lazyGetUserNameOrigin then originText gt const lazyDisplayResult displayResult originText lazyDisplayResult function main void const lazyOriginNameService originNameService lazyOriginNameService Here only the main function is non deterministic the remaining functions are all side effect free thanks to the wrapper functions That being said writing tests for these pure functions would not be very useful as we would not test their actual behavior expect askForUserName to be a function expect getUserNameOrigin foo to be a function expect displayResult bar to be a function To overcome this we could use Dependency Injection a k a DI This is a bit out of scope for this article but essentially we would pass the actual effect i e prompt fetch as a dependency of the function and we would use a mocked controlled version of this effect for writing the unit tests For example interface Dependencies prompt text string gt string function askForUserName prompt Dependencies gt string return gt prompt What is your name const lazyUserName gt string askForUserName prompt window prompt const fakePrompt text string gt foo const lazyUserName gt string askForUserName prompt fakePrompt expect lazyUserName to be a function expect lazyUserName to equal foo What if we wrote a simple type alias for the introduction of laziness type IO lt A gt gt Afunction askForUserName IO lt string gt function getUserNameOrigin userName string IO lt Promise lt string gt gt function displayResult text string IO lt void gt function originNameService IO lt Promise lt void gt gt function main void And what about a special alias for the lazy promises type Task lt A gt IO lt Promise lt A gt gt function askForUserName IO lt string gt function getUserNameOrigin userName string Task lt string gt function displayResult text string IO lt void gt function originNameService Task lt void gt function main void The type of main is gt void so in other words main IO lt void gt Also askForUserName and originNameService do not take any argument so they are already lazy We can simplify their definition with const askForUserName IO lt string gt const originNameService Task lt void gt const main IO lt void gt Now imagine if these IO and Task types had some behavior attached to them allowing us to do something such as const originNameService Task lt void gt Task fromIO askForUserName andThen getUserNameOrigin andThen text gt Task fromIO displayResult text This is how we can contain side effect declarations inside values that we can compose with other values thus describing more and more complex side effects To run the side effects we can simply run the final value obtained from the composition assuming we have some behavior attached to our Task lt void gt valueoriginNameService runEffect Here I presented one approach we can use to handle side effects We have separated their declaration from their execution giving us more flexibility to combine these effects and more control over what happens in our program Functional languages and libraries provide standard tools to deal with side effects so we do not have to build them ourselves Haskell has a built in IO data type The fp ts TypeScript library provides both IO for synchronous side effects and Task for asynchronous ones The cats effect Scala library provides the IO data type as well Writing functional programs will undoubtedly lead you to use these data types to deal with side effects The goal is to have as many side effect free functions as possible in our programs by leveraging side effects declarations and isolating side effects execution This concludes the chapter on side effects Hopefully you enjoyed it and understood what side effects are and how you can deal with them The next step is to talk about function purity and referential transparency As always feel free to leave a comment See you then Special thanks to Tristan Sallé for reviewing the
