海外TECH	DEV Community	What is DNS TTL (Time To Live)?	https://dev.to/easyawslearn/what-is-dns-ttl-time-to-live-g87	What is DNS TTL Time To Live What is time to live TTL Time to live TTL is a value for the period of time that a packet or data should exist on a computer or network before being discarded The meaning of TTL or packet lifetime depends on the context For example TTL is a value in an Internet Protocol IP packet that tells a network router when the packet has been in the network too long and should be discarded Here s the full video along with a hands on demo that s based on TTL time to live How Does TTL Work TTL s basic function revolves around managing information packets in relation to DNS requests When one of these packets is created and transmitted through the internet there is a chance that it will pass continuously from router to router forever To prevent this from happening each packet has a specific TTL or hop limit It is also possible to examine the TTL log of a data packet to obtain information on how it has moved through the internet over the course of its travels Within each packet there is a specified place where the TTL value is stored This is a numerical value and it indicates how much longer the packet should move around the internet When a router receives a data packet it takes away one unit from the TTL count before sending it on to the next destination within the network This continues to happen until the TTL count within the packet drops all the way down to zero What is time to live in HTTP In Hypertext Transfer Protocol HTTP time to live describes the number of seconds it takes for cached web content to return before the webserver has to check again to ensure that the content is fresh Settings on the webserver define a default value Still cache control tags which define the kinds of servers if any can cache the data or expired tags which represent a date and time when the content is stale can override it in the HyperText Markup Language page headers What Are TTL Values When you set TTL values for your website you choose a value in seconds For example a TTL value of is the equivalent of seconds or ten minutes The minimum available TTL is usually equivalent to seconds You could theoretically set a TTL as low as one second However most sites use a default TTL of one hour The maximum TTL that you can apply is hours Technically you can set any TTL value between the minimum and maximum parameters Later in this article we ll discuss how you can choose the best time to live value for your site How Should You Choose a TTL Deciding on a suitable TTL for your needs can be challenging Fortunately there are some general guidelines that you can follow to see what fits your site best We recommend a TTL of hours for most sites Remember that TTL values are measured in seconds so this is the equivalent of to seconds This TTL value can reduce loading time which improves the user experience for your visitors and can decrease your bounce rate The longer the better is a general rule but remember to schedule any website maintenance accordingly WANT TO LEARN MORE Full Terraform tutorial DevOps Tools like Ansible Docker Tutorial	2021-12-29 17:41:55

海外TECH	DEV Community	Flash of Undefined Custom Elements (FOUCE)	https://dev.to/claviska/flash-of-undefined-custom-elements-fouce-3bp4	Flash of Undefined Custom Elements FOUCE Web components are defined and registered with JavaScript Depending on how and when you load the scripts that perform registration you may see a brief flash of unstyled HTML where your custom elements should be when the page loads This is not dissimilar to FOUC which occurs when HTML is displayed before the stylesheet has loaded For reference here s an exaggerated example of three custom elements loading at different intervals Since the world needs more acronyms and since one doesn t seem to exist yet I m calling this phenomenon FOUCE rhymes with spouse which stands for Flash of Undefined Custom Elements Fortunately the browser gives us some tools to mitigate it Script placementThe easiest way to prevent FOUCE is to put the lt script gt tag s that load your custom elements in the lt head gt section of the page While this approach is simple it will block rendering until all scripts are processed which can adversely affect page load times lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt title gt Example lt title gt lt Custom elements are loaded here gt lt script src my card js type module gt lt script gt lt script src my button js type module gt lt script gt lt script src my rating js type module gt lt script gt lt head gt lt body gt lt body gt lt html gt I recommend this approach only if you re loading a handful of small custom elements or if you re building something like an Electron app where resources are loaded locally rather than over HTTP Generally speaking you probably don t want to do this in a browser The defined selectorA better approach is to use the defined CSS pseudo class to hide custom elements that haven t been registered yet You can scope it to specific tags or you can hide all undefined custom elements as shown below not defined visibility hidden As soon as a custom element is registered it will immediately appear with all of its styles effectively eliminating FOUCE Note the use of visibility hidden instead of display none to reduce shifting as elements are registered The drawback to this approach is that custom elements can potentially appear one by one instead of all at the same time That s certainly a lot better but can we take things even further Awaiting customElements whenDefined The last option is to use customElements whenDefined which returns a promise that resolves when the specified element gets registered You ll probably want to use it with Promise all A clever way to use this method is to hide the lt body gt with opacity and add a class that fades it in as soon as all your custom elements are defined lt style gt body opacity body ready opacity transition s opacity lt style gt lt script type module gt await Promise all customElements whenDefined my button customElements whenDefined my card customElements whenDefined my rating Button card and rating are registered now Add the ready class so the UI fades in document body classList add ready lt script gt In my opinion this is the best approach because it subtly fades in the entire page as soon as all your custom elements are registered After all what s the point of showing the page before it s ready The drawback of course is that you need to keep track of which elements you re using and add them to the list But this can also be an advantage if your initial UI only requires a handful of custom elements For example you can load only the ones you need upfront and let the rest of them load asynchronously to make your page load faster Have you used any of these methods to prevent FOUCE Have you thought of a better way Let me know on Twitter This article was originally published on the author s blog	2021-12-29 17:15:27
