海外TECH	DEV Community	Scheduling API Roadblocks	https://dev.to/spurwing/scheduling-api-roadblocks-4mc0	Scheduling API RoadblocksAt first blush implementing scheduling functionality in your application or website looks like it would be the simplest thing in the world to pull off After all the actual process for using most scheduling solutions is pretty much as “point and click as it gets with new appointments and events scheduled in about seconds or less Common Scheduling API Roadblocks Developers Need to OvercomeBeneath the surface of that super user friendly experience however is something far more complex So complex in fact that a lot of developers learn relatively early on in the development process that it makes a lot more sense to use scheduling API services to overcome common obstacles than trying to build something from scratch reinventing the wheel along the way Below we highlight some of the biggest obstacles developers come across when working with scheduling systems and why it makes so much sense to lean on scheduling API services to shortcut development time and improve results Let s take right in Incorporating Multiple Scheduling APIsWhile almost all popular calendar platforms operate similarly as far as functionality is concerned the code API and “hooks running under the hood couldn t be more unique Google Outlook Exchange and the Office calendar systems all have their own unique API that makes integration possible But integrating all of those APIs together with outside APIs as well can become a real spaghetti situation in a hurry Everything starts to “tangle pretty quickly and before you know it it s almost impossible to keep your scheduling solution tight organized and well optimized By using API scheduling services that act as a single point of contact for multiple calendar APIs however you re able to smooth things out and streamline your app or service significantly Scheduling Across Multiple CalendarsIf you combine the unique complexity of multiple calendar applications with the fact that they treat event appointment creation directives as second class objects it s not hard to see how things can spiral out of control when you have unified scheduling across multiple calendars By using a single API service to manage all second class objects even transforming them into first class objects across multiple calendar platforms everything smooths out significantly Less resources are used event creation requests are handled much faster and at the end of the day managing events across multiple different calendar platforms becomes almost effortless Scheduling Across Multiple TimezonesDealing with scheduling across multiple time zones is one of those things that often goes overlooked by new developers working with calendar and scheduling APIs for the first time at least until everything breaks under real world testing anyway Any applications that are going to be responsible for managing events that span across multiple regions and multiple time zones need to be engineered to “normalize time With scheduling API services time isn t just normalized on the user end of things always displaying the right time for each user depending on their specific time zone while keeping things synchronized But they also make it easy to manage update and instance the timing of events across multiple time zones on the backend too Synchronized Scheduling with Multi User AvailabilitiesOne of the core functionalities that a scheduling solution needs to include is the ability to find schedule availability across multiple users allowing end users to schedule appointments and events in “open space shared by everyone using that calendar specifically Standard calendar API solutions take advantage of “free busy resources to handle this on their own And while that does a solid job for single users on one calendar application things break down pretty quickly when you re trying to manage multiple calendars and multiple users at once all with their own unique schedules Top of the line scheduling API services eliminate this obstacle by synchronizing schedules in real time across multiple user and multiple calendar instances This keeps everyone on the exact same page with limited potential for overbooking or mismatched schedules to pop up later down the line ConclusionAt the end of the day scheduling API services shortcut development time significantly overcome the obstacles highlighted above and more and should be leveraged at every opportunity rather than trying to reinvent the wheel and building this functionality from scratch Learn how Spurwing s API can help your project or business succeed Website Blog Marketplace	2021-05-08 20:53:57

海外TECH	DEV Community	Tailwind CSS might not be for you	https://dev.to/benface/tailwind-css-might-not-be-for-you-jk0	Tailwind CSS might not be for youDisclaimer This article is my version of Tailwind CSS Adds complexity does nothing I respect the original author s opinions but I think there s a better way to criticize Tailwind CSS Here goes If you work in the front end you ve probably heard a lot about Tailwind CSS a CSS library much like Bootstrap Much unlike Bootstrap however Tailwind takes a different approach it is almost exclusively “utility classes And it might not be for everyone Before we start let me try to explain what a utility class is Let s say that you have many components and many of them need to have the CSS declaration display flex Instead of writing that over and over in your CSS you create a class called flex flex display flex Then in every component that needs to be flexed you add that flex class This is not a bad thing I have written and used utility classes a great deal myself especially when I m writing CSS without the aid of CSS in JS solutions or a preprocessor like Sass SCSS What Tailwind does is take that concept to the extreme with the idea being that you almost never have to write CSS you just add different classes to your HTML based on what styles you need to apply Which is an interesting choice because This is embracing inline stylesBack before stylesheets were a thing HTML had elements such as lt font gt and lt center gt to apply some basic styles directly in the markup much like the style attribute that came along with CSS But while inline styles are still a thing nowadays we know better than to use them since we have stylesheets now which let us “separate concerns HTML is for content and structure CSS is for presentation However Tailwind doesn t adhere to that idea and goes back to the s way of mixing content and presentation in the same file So why not just use inline styles then Writing lt div class flex gt foo lt div gt has the same exact effect as writing lt div style display flex gt foo lt div gt Well turns out there are a couple reasons as outlined in the Tailwind documentation Notably inline styles don t support media queries or pseudo class selectors such as hover or focus so you can t have responsive or dynamic styles with them Building a whole app or website with inline styles would be impossible for that reason alone unless you decide to pretend that mobile devices don t exist If that s not reason enough Tailwind makes a strong argument for “designing with constraints Using inline styles every value is a magic number With utilities you re choosing styles from a predefined design system which makes it much easier to build visually consistent UIs Indeed Tailwind s theme configuration is one of its greatest strengths It prevents your stylesheet from containing unique font sizes and some background colors that are different but so similar that they should clearly be the same e g ffee and ffe It also helps developers design faster and be more confident that they re not introducing visual inconsistencies But even though Tailwind improves a lot on inline styles it still embraces their philosophy and suggests that it s totally fine even desirable to mingle presentation with content Consequently some of the arguments that you could make against using inline styles are also arguments against using Tailwind I know it seems a bit lazy to rehash other users criticisms of inline styles to explain why Tailwind might not be for you but let s do it anyway It s WET not DRYWhen you want to change your site s styling in a major way if you ve used utility classes you need to go through each use of those utility classes that is every component and visually determine what needs to be updated For example let s say that your company s primary color is blue You ll have lots of blue stuff in your website marked with classes like text blue or bg blue which represent different shades of blue And that s fine until your company decides to rebrand and all of the buttons on the site but only the buttons need to be red If you were using regular old CSS you would probably have a class called button You would just go into that class in your CSS and change a single line background color red Any element that uses that class definition would now be red Instead with Tailwind you have to go through each component and manually change bg blue to bg red And with edits comes opportunities to introduce a bug It is almost a textbook definition of why the DRY principle is in place That is unless you bring back the abstraction that you lost by replacing button with a bunch of utility classes in your HTML In my experience Tailwind works best if anything that used to be a “CSS component like the button class is made a “template component a reusable file that includes both the markup and the styling That makes sense when you think about it and you end up removing even more duplication not just the Tailwind classes which now live in a single file instead of but any attribute think ARIA or child element of the component think button icon Turns out how DRY your code ends up being is up to you not up to Tailwind The above assumes that you re using some kind of component library e g React Vue Svelte etc or templating language that supports partials Twig Blade PHP etc If you re not or if you find that it would be cumbersome to create a component or partial for a simple button that s totally fine You don t have to change your abstraction model you can still use CSS itself as your “component layer That s where Tailwind s apply feature comes in handy you keep your button class but instead of writing background color red you write apply bg red That way you re still using the theme configuration instead of a hard coded magic value This is similar to what you can do with preprocessors or CSS variables but using the Tailwind API HTML is traditionally concerned with structure not stylingPeople talk about separation of concerns a lot in development CSS Modules and especially vue files have done a lot to dispel the notion that you need to segregate structure behavior and style of each building block of your site in separate folders but there is something to be said for separating concerns That is each part of your code should be “loosely coupled and highly cohesive In other words your HTML structure syntax shouldn t have information about what the styles should be it should only contain information about the structure of the page Indeed the ultimate reason for the invention of CSS the whole point of the entire enterprise of CSS was specifically so that you could separate content from presentation And yet Tailwind embraces the idea of inline styles which goes against that whole concept Why is that Adam Wathan the author of Tailwind has written an article about how separation of concerns is “a straw man and we should instead think of it in terms of “dependency direction It s a long read but it s worth it to understand where Tailwind comes from Tailwind like most CSS frameworks is targeted towards developers who prefer writing HTML that depends on CSS over CSS that depends on HTML Adam mentions that both approaches are perfectly valid and it comes down to “what s more important to you in a specific context Tailwind takes the first approach and goes as far as it can with it As a result developers can build custom UIs right in the HTML because the CSS provides all the necessary building blocks When we write code we write it for two audiences the first is the computer itself which doesn t care how the code looks so long as it runs and the other is our fellow programmers The easier it is for them to quickly identify what parts of your program are and how they interrelate the more quickly they can fix bugs add features and bring value to the organization Tailwind makes it easy not only to build UIs without switching context but also to understand what each element looks like at a glance since the styles are right there in the same file The flip side of losing “semantic class names in favor of utility classes is that it becomes not as obvious what a given piece of HTML represents in terms of content Thankfully that is easily mitigated by using well named components or adding comments or even classes that do nothing but describe what an element is as the first class so it s not lost in the sea of utilities obviously It s hard to read at firstIf you look at some HTML with Tailwind in it you might say to yourself that the HTML looks “busy or even “ugly That s true but some say you get used to it The real catch is that you have to learn all these classes before you can be productive with it even if you know CSS really well Tailwind is full of semantically obscure abbreviations such as w for width and h for height The framework tries to find a balance between terseness and expressiveness but it can definitely feel cryptic at first Here s an example from Aleksandr Hovhannisyan This Tailwind code lt div class w h rounded text white bg black py px m text sm md w md h md rounded md md text base lg w lg h lg rounded lg lg text lg gt Yikes lt div gt could be expressed as lt style gt thing width rem height rem color white background color black padding rem rem margin rem border radius rem font size rem line height rem media screen and min width px thing width rem height rem border radius rem font size rem line height rem media screen and min width px thing width rem height rem border radius rem font size rem line height rem lt style gt lt div class thing gt Yikes lt div gt As you can see there are pros and cons to each approach The second example is much more expressive especially if you don t know Tailwind but it s a lot more code and the styles are separate from the element they are affecting The Tailwind code on the other hand is short and you don t need to open another file to understand how it s styled You may find it cryptic but after just a couple days of using it you should be able to decipher it pretty easily It s worth noting that Tailwind classes are arranged horizontally while the CSS is written vertically The wider text is the harder it is for a reader s eyes to jump to the next line and the harder it is to find the one particular word you re looking for in a wall of horizontal text That s part of the reason why Tailwind classes are terse in addition to typing speed and file size Note that there are different ways to mitigate lines getting too long enabling wrapping in your IDE adding line breaks using apply selectively etc but it is a potential issue to be aware of Again this is a matter of preference Tailwind might be for you or it might not but it s hard to know without giving it a real try You lose a lot of the features built into standard CSS if you insist on not using any custom CSS But realistically most Tailwind projects have some custom CSS which is totally fine Tailwind itself is a PostCSS plugin meaning it runs on CSS source files not instead of So if you want some specific styling rules for instance to add some margin between p tags inside a description class you ll have to write custom CSS though nothing prevents you from using apply description p p apply mt Note that there are also lots of plugins including some official ones such as Typography and Forms for extending Tailwind s core functionality It solves a problem that you may not have encounteredWe re all different We work on different projects have different methodologies use different tools One tool cannot claim to solve a problem that everyone is having The best it can do is exist for the people who are experiencing the specific problem it was built to solve and provide great documentation and other resources to learn about how it can make your work or your life easier Tailwind does just that It s not for everyone If you ve read Adam Wathan s CSS Utility Classes and Separation of Concerns article and couldn t relate I m happy to tell you that Tailwind is probably not for you If you love writing custom CSS or need to apply different stylesheets to the same HTML to radically change how it looks Tailwind is not for you That s OK Go build great things with your favorite tools Nothing is perfectSomething else will come along eventually solving some of Tailwind s problems and maybe it will introduce new problems that we can t even imagine Maybe it will be a core web technology who knows But in the meantime if you decide that Tailwind is for you or your team it s going to provide a great developer experience with some of the best documentation I ve ever seen in an open source project your CSS is going to be as small as ever and after a while you might just wonder how you ever did CSS any other way	2021-05-08 20:03:20
