JavaScript localStorage The complete guide IntroductionJavaScript localStorage is basically storage that is in the browsers Window Object You can store anything in the localStorage and it will be persistent through page loads and even if the browser closes and reopenslocalStorage and its related sessionStorage are part of the Web Storage API We will be learning more about these below What is Web Storage API Web Storage API provides methods through which browsers can store key value pairs of data like Objects The key value pairs stored in the web storage API are always in the form of strings integer keys are automatically converted to strings There are a set of methods provided by the Web Storage API that you can use to access delete modify the key Value pairsThere are two types of storage available in the Web Storage APIsessionStoragelocalStorage What is LocalStorage LocalStrorage is part of the Web Storage API It allows you to store persistent data data remains on the browser reloads and when the browser is closed and reopened in the browser Window Object as key value pairs of strings There are five methods of localStorage and these are setItemgetItemremoveItemclearkey Difference between sessionStorage and localStorageBoth sessionStorage and localStorage are part of the web storage api The sessionStorage is only available till the browser is open when the browser is closed the sessionStorage is deleted sessionStorage is available when the browser reloads but when the browser is closed sessionStorage is deleted The localStorage is the persistent data even when the browser is closed the localStorage data remains in the browserlocalStorage can be deleted manually by the user and it is automatically deleted when the user is in an incognito window or private window and the user closes the browserBoth sessionStorage and localStorage provides similar methods to access and store data in the browserWe will be learning more about the LocalStorage methods below localStorage MethodsThere are five methods in the localStorage These methods let you store items get Items remove Items and clear the localStorage setItem Store data in the localStorageUsing localStorage setItem API you can store key value pairs in the local storage here is an example on how you can store the data window localStorage setItem candy name Mars Bar the candy name is the key and the Mars Bar is the value As we have mentioned localStorage only stores strings You can try this in the browser itself Here is an example to storing the data in the chrome browserThere are multiple ways of storing the data in the localStorage using setItem You can access data in the Object like way window localStorage candyName Mars window localStorage candyName Mars window localStorage setItem candyName mars It is allowed but not recommended to store or access data in the object like way because the user generated key can by anything like toString or length or any other built in method name of the localStorageIn which case the getItem and setItem would work fine but the Object like method would failusing Object like notation getItem Retrieve data from the localStorageUsing the getItem API we can retrieve the key value pairs stored in the localStoragegetItem accepts a key and returns the value as a stringThis would return the value as Mars Barusing Object NotationUsing Object notation you can also access the data although it is not recommended window localStorage candyNamereturns Mars window localStorage candy returns turtles removeItem Remove an item from the localStorageyou can remove any item from the localStorage using the removeItem methodPass the key of the item that you need to remove to the removeItem method and it is deleted from the localStoragewindow localStorage removeItem candies let s use the console to see how the removeItem works First we will use the length property to check how many items are in the local storageAs you can see when we use the length property it shows there are items in the localStorage After we remove an item now there is only one item remaining in the local storage clear clear the localStorageWith Clear method of the localStorage API you can clear the entire localStorage and delete all the data in the localStoragewindow localStorage clear let us use the console to see how the clear method of the localStorage worksWe will use the length to check for the number of items in the localStorage key returns the n th key in the storagethe key method can be passed any integer and it will return the key stored at the nth key in the storage Objectwindow localstorage key index Let us use the console to see how the key worksWe have put key value pairs in the localStorage likewindow localStorage candyName Mars window localStorage candy turtles let us use the length to check for the contents of the localStoragewindow localStorage lengthas you know the index starts from let us see what is at index and let us see what is at index Storage Property length number of key value pairs stored in the localThe length is a read only property of the localStorage interface It returns the number of key value pairs stored in the localStoragewindow localStorage lengthWe can use length property to test whether the localStorage is populated or not Uptill now we have used the length property multiple times and you might have become familier with Let us use the length property in different use cases to futher explore its uses Let us open the console and see how we can use the length propertywindow localStorage lengthnow the length property can also be used to check if the localStorage is empty Let us clear the localStorage and see what happens if we use the length propertyIt returns hence we know if the length property returns then the localStorage is empty Storage EventThe storage event is fired whenever a change is made to the storage ObjectStorageEvent is sent to the window when a storage area the window has access to is changed within the context of another documentStorage event are events that are fired whenever a change takes place and you can listen to the storage event and make appropriate decision in your website or application ConstructorStorageEvent Returns a new StorageEvent Objectlet us use the console to create a new instance of the storageEvent creating a new instance of the StorageEventnew window StorageEvent keys returns Instance Properties Keys read only Returns a String that represents the key that has been changed The key attribute is null when the change is caused by the clear method newValue read only Returns a String with the new value of the key that has been changed It is null when clear method has been used or the key has been removed oldValue read only Returns a String with the original value of the key It is null when a new key has been added where there was no key before storageArea read only Returns a storage Object that represents the storage area that was affected url read only Returns a string with the url of the document who key is changed LocalStorage Interesting factsHere are some of the interesting facts about the localStoragelocalStorage is always stored in UTF string format Integer keys are converted into string and stored in the localStoragelocalStorage data is specific to the protocol of the browser and website For example it is different in HTTP and HTTPSfor documents loaded from file the requirements for localstorage is undefined and is different for different browserslocalStorage for incognito or private browsers is deleted when the browser is closed LocalStorage LimitationsHere are some of the limitations for localStorageLimited upto MB of datado not store sensitive data in localStorage as it can be easily accessed by cross site scriptinglocalStorage is synchronous meaning it is accessed one after the other anddo not use localStorage as a database Detecting localStorage testing for availability Browser CompatibilityLocalStorage is compatible with all the latest browsers Only the very very old browsers like Internet Explorer or do not support localStorageIn some situations like the user is in private window or the user is in incognito window the data would be immediately deleted when the user closes the windowThe user can also disable localStorage ExceptionssecurityErrorA security error is thrown in the following cases Origin is not a valid scheme host port tuple error This happens when the origin uses file or data schemes Many modern browsers treat file origin as opaque origin What this means is that the file or files that come from the same folder are assumed to come from different sources and could trigger CORS errorThe request violates a policy decision For example the user has disabled the use of localStorage on the browser ConclusionIn this article I have explained the localStorage and its methods and how you can use localStorage to save data and access it deleted it and modify itNote This article was originally written on the DeadSImpleChat Blog JavaScript localStorage The Complete Guide |

Virgin Galactic will start commercial spaceflight as soon as June thAfter years of development Virgin Galactic is finally ready to take paying customers The company has confirmed that its first commercial spaceflight Galactic will launch between June th and June th This inaugural mission will carry three people from Italy s Air Force and National Research Council as they conduct microgravity research Virgin had anticipated a late June start but hadn t committed to that window until now The company already has follow up flights scheduled Galactic is expected to launch in early August and will carry a private crew Virgin will fly on a monthly basis afterward although details of future missions aren t yet available At least the first two flights will stream live through the company s website Virgin conducted its last pre commercial flight test its fifth spaceflight of any kind in late May The company faced numerous delays and incidents getting to that point however The company completed its first SpaceShipTwo test flights in but paused its efforts after the deadly crash of VSS Enterprise Flight testing didn t resume until VSS Unity s glide test at the end of The firm finally reached space in but had to wait until to complete its first fully crewed spaceflight with founder Richard Branson aboard It pushed back commercial service multiple times due to varying factors most recently delays in upgrading the VMS Eve quot mothership quot that carries SpaceShipTwo vehicles to their launch altitude The debut is important for Virgin s business Virgin has operated at a loss for years losing more than million just in Commercial service won t recoup those investments quickly even at per ticket but it will give the company a significant source of revenue This isn t the start of space tourism for Virgin In that sense it s still trailing Blue Origin Galactic will put Virgin ahead of SpaceX though as that company s Starship rocket has yet to reach space and isn t expected to launch its first lunar tourist flights until late at the earliest While Virgin is less ambitious than Elon Musk s operation it s also achieving its goals sooner This article originally appeared on Engadget at |
