海外TECH	DEV Community	The correct way to fetch data from API	https://dev.to/shashank1503cipher/the-correct-way-to-fetch-data-from-api-4l4b	The correct way to fetch data from API IntroductionThis article will tell you how to correctly fetch data from APIs in React From making efficient API requests to delivering good user feedback it covers it all Tech StackI am going to use Chakra UI for UI components you can use any UI Component library you like or even create your own UI Components I will be using a public Joke API to demonstrate you the process You can take a look at it s swagger docs here Creating React AppLet us first create a React App with Chakra ui s template Let s name it Punbytes Type the following in your command line npx create react app punbytes template chakra uiAfter the above CLI code has been successfully executed It would create a boilerplate for you to work on which would look like this Cleaning the codeThe only thing which I ll be using here is the color mode switcher which let s you switch color modes I am just keeping it for my personal preference If you want you can remove it After that I ll just create a logo using lt Heading gt component of Chakra ui Now our App js would look like thisimport React from react import ChakraProvider theme Flex Heading from chakra ui react import ColorModeSwitcher from ColorModeSwitcher function App return lt ChakraProvider theme theme gt lt Flex justifyContent space between p gt lt Heading gt Punbytes lt Heading gt lt ColorModeSwitcher justifySelf flex end gt lt Flex gt lt ChakraProvider gt export default App Creating some front end for the APIWe can add a big text in the front containing the Joke and a button which fetches new joke import React from react import ChakraProvider theme Flex Heading Text Button from chakra ui react import ColorModeSwitcher from ColorModeSwitcher function App return lt ChakraProvider theme theme gt lt Flex justifyContent space between p gt lt Heading gt Punbytes lt Heading gt lt ColorModeSwitcher justifySelf flex end gt lt Flex gt lt Flex justifyContent center alignItems center minH vh gt lt Text fontSize xl textAlign center gt Joke lt Text gt lt Flex gt lt Flex justifyContent center center flex end flex end mr mb gt lt Button gt Another One lt Button gt lt Flex gt lt ChakraProvider gt export default App Our webpage would look like this Fetching data from the APITo fetch data we ll make use of fetch along with async await for asynchronous programming But first we need to create some states that will be updated We ll require a state for joke a state to show loading and a state for error As we are using functional components we ll make use of useState Hook to create state We ll add the following code to the top level of our functional component const joke setJoke useState const loading setLoading useState false const error setError useState Now that we have states let us create the function that would retrieve data from the API We ll create an asynchronous function using async await const getJoke async gt setLoading true try const res await fetch const data await res json setJoke data joke catch error console error error setError error setLoading false This function is going to be invoked at the load time as well as on clicking another one button To invoke it at the load time we ll call this function in a useEffect Hook for one time useEffect gt getJoke The empty dependency array denotes that the useEffect should run only once Now we can also add this function to onClick of our Another One Button lt Button onClick getJoke gt Another One lt Button gt Updating the front endNow we can update the front end according to our states We ll first add a loader which makes use of loading state We ll make use of lt Spinner gt component to display loading loading lt Flex minH vh fontSize xl justifyContent center alignItems center gt lt Spinner size xl gt lt Flex gt lt gt lt Flex justifyContent center alignItems center minH vh gt lt Text fontSize xl textAlign center gt joke lt Text gt lt Flex gt lt Flex justifyContent center center flex end flex end mr mb gt lt Button onClick getJoke gt Another One lt Button gt lt Flex gt lt gt Now we ll also add error display in case of any error For that we ll make use of error State For the front end part we ll use lt Alert gt component of Chakra UI loading lt Flex minH vh fontSize xl justifyContent center alignItems center gt lt Spinner size xl gt lt Flex gt error lt Alert status error gt lt AlertIcon gt lt AlertTitle gt error title lt AlertTitle gt lt AlertDescription gt error message lt AlertDescription gt lt Alert gt lt gt lt Flex justifyContent center alignItems center minH vh gt lt Text fontSize xl textAlign center gt joke lt Text gt lt Flex gt lt Flex justifyContent center center flex end flex end mr mb gt lt Button onClick getJoke gt Another One lt Button gt lt Flex gt lt gt The final code would look like this import React useEffect useState from react import ChakraProvider theme Flex Heading Text Button Spinner Alert AlertIcon AlertTitle AlertDescription from chakra ui react import ColorModeSwitcher from ColorModeSwitcher function App const joke setJoke useState const loading setLoading useState false const error setError useState const getJoke async gt setLoading true try const res await fetch const data await res json setJoke data joke catch error console error error setError error setLoading false useEffect gt getJoke return lt ChakraProvider theme theme gt lt Flex justifyContent space between p gt lt Heading gt Punbytes lt Heading gt lt ColorModeSwitcher justifySelf flex end gt lt Flex gt loading lt Flex minH vh fontSize xl justifyContent center alignItems center gt lt Spinner size xl gt lt Flex gt error lt Alert status error gt lt AlertIcon gt lt AlertTitle gt error title lt AlertTitle gt lt AlertDescription gt error message lt AlertDescription gt lt Alert gt lt gt lt Flex justifyContent center alignItems center minH vh gt lt Text fontSize xl textAlign center gt joke lt Text gt lt Flex gt lt Flex justifyContent center center flex end flex end mr mb gt lt Button onClick getJoke gt Another One lt Button gt lt Flex gt lt gt lt ChakraProvider gt export default App The output would be like this ConclusionWe have now covered a brief intro to fetching data from APIs Further we can analyze and create specific errors for Status Codes returned by HTTP Request We can also look into the cleaning part of useEffect when we are fetching data from API based on a dependency Typical example would be autocomplete feature Thank you for reading	2022-06-09 04:29:06
海外TECH	DEV Community	Introduction To Arrays	https://dev.to/abbhiishek/introduction-to-arrays-4d59	Introduction To ArraysWe all know that we can use a variable to store a single value but if we have to store values at a time then declaring and initializing variables is not an optimized way of doing things For this purpose we have arrays in C to store data of a similar data type Arrays in C are classified into one dimensional two dimensional and multi dimensional arrays Array indices always start from and end with size What is an Array An array is a collection of one or more values of the same data type stored in contiguous memory locations The data type can be user defined or even any other primitive data type Elements of an array can be accessed with the same array name by specifying the index number as the location in memory Types of ArraysArrays in C are classified into three types One dimensional arraysTwo dimensional arraysMulti dimensional arrays Introduction to One Dimensional Array in CWe can visualize a one dimensional array in C as a single row to store the elements All the elements are stored at contiguous memory locations Now we will see how to declare initialize and access array elements Array DeclarationWhile declaring a one dimensional array in C the data type can be of any type and also we can give any name to the array just like naming a random variable Syntax int arr arr is the array name of type integer and is the size of the array Array InitializationIn static uninitialized arrays all the elements initially contain garbage values but we can explicitly initialize them at their declaration Syntax lt data type gt lt arr name gt arr size value value value … Here parameterized values are constant values separated by a comma We can skip the writing size of the array within square brackets if we initialize array elements explicitly within the list at the time of declaration In that case it will pick elements list size as array size Example int nums array nums is initialized with elements If we want to initialize all elements of an integer array to zero we could simply write int lt array name gt size Array AccessingIn one dimensional arrays in C elements are accessed by specifying the array name and the index value within the square brackets Array indexing starts from and ends with size If we try to access array elements out of the range the compiler will not show any error message rather it will return some garbage value Syntax lt arr name gt index Example int nums printf d nums Array element at index is printedprintf d nums Garbage value will be printedC Program to illustrate declaration initialization and accessing of elements of one dimensional array in C include lt stdio h gt int main int arr declaring and initializing one dimensional array in C After declaration we can also initialize array as arr arr arr for int i i lt i accessing elements of array printf Value of arr d d n i arr i Output Value of arr Value of arr Value of arr In this C programming code we have initialized an array at the time of declaration with size and array name as arr At the end of the code we are trying to print the array values by accessing its elements Rules for Declaring One Dimensional Array in CBefore using and accessing we must declare the array variable In array indexing starts from and ends at size For example if we have arr of size then the indexing of elements ranges from to We must include data type and variable names while declaring one dimensional arrays in C We can initialize them explicitly when the declaration specifies array size within square brackets is not necessary Each element of the array is stored at a contiguous memory location with a unique index number for accessing Initialization of One Dimensional Array in CAfter declaration we can initialize array elements or simply initialize them explicitly at the time of declaration One Dimensional arrays in C are initialized either at Compile Time or Run Time Compile Time InitializationCompile Time initialization is also known as static initialization In this array elements are initialized when we declare the array implicitly Syntax lt data type gt lt array name gt array size list of elements Example int nums C Program to illustrate Compile Time Initialization include lt stdio h gt int main int nums printf Compile Time Initialization Example n printf d nums printf d nums printf d nums Output In this C program code we have initialized array nums of size and elements as and in the list This is compile time initialization and then at the end we have printed all its values by accessing index wise Run Time InitializationRuntime initialization is also known as dynamic initialization Array elements are initialized at the runtime after successfully compiling the program Example scanf d amp nums initializing th index element at runtime dynamicallyC Program to illustrate Run Time Initialization include lt stdio h gt int main int nums printf n Run Time Initialization Example n printf n Enter array elements for int i i lt i scanf d amp nums i printf Accessing array elements after dynamic Initialization for int i i lt i printf d nums i return InputRun Time Initialisation Example Enter array elements Output Accessing array elements after dynamic Initialization To demonstrate runtime initialization we have just declared array nums of size in this C programming code After that within a loop we are asking the user to enter the array values to initialize it after the compilation of the code In the end we have printed its values by accessing them index wise Copying One Dimensional Arrays in CIf we have two arrays array and array one is initialized and another array is just declared and suppose if we have to copy array elements to array then we can t simply just write int array int array array array This statement is wrong it will produce an errorThe primary condition to copy an array is that the copy array s size should be less than the original array Program to illustrate copying of elements of a one dimensional array in C include lt stdio h gt int main int array int array printf Copying One Dimensional Arrays in C n printf Array elements for int i i lt i printf d array i array i array i Copying array elements to array printf nArray elements after copying for int i i lt i printf d array i Output Copying One Dimensional Arrays in C Array elements Array elements after copying In this C programming code we have taken two arrays array and array array has been initialized at the time of declaration and to illustrate the concept of copying array elements we are assigning array values to array within a loop In the end we have printed the values of both arrays Points to Remember About Array in CArrays in C are a collection of similar data type elements stored at contiguous memory locations In arrays in C all the elements have the same data type and can be accessed by their unique index value Array indexing starts from and ends with size One dimensional arrays in C can be initialized statically during compile time or dynamically during runtime We must include the data type variable name for the array and size of the array in square brackets while declaring one dimensional arrays in C ConclusionArrays in C have derived data types containing similar data type elements In one dimensional arrays in C indexing starts from and ends at size and if we try to access an element out of range it will return a garbage value We must include a data type variable name for array and array size in square brackets while declaring one dimensional arrays in C One dimensional arrays in C can be initialized statically during compile time or dynamically during runtime All the elements of an array are stored at contiguous memory locations and therefore we can access them using their unique index number	2022-06-09 04:23:01
海外TECH	DEV Community	Compass Heading with AnimatedRotation in Flutter	https://dev.to/rlazom/compass-heading-with-animatedrotation-in-flutter-3ji2	Compass Heading with AnimatedRotation in Flutter Create an smooth angle transition for the users in your map applicationSo I m working on a project that involves a map One of the requirements was to update not only the position but also were the user points to To do this I integrated the following plugins into the app flutter compass A Flutter compass The heading varies from being north flutter map A versatile mapping package for Flutter based off leaflet js that s simple and easy to learn yet completely customizable and configurable For full documentation on the flutter compass plugin see the the example page on pub dev Now to get the continuous changes in the user s heading we need to subscribe to the API provided by the flutter compass plugin double userHeading FlutterCompass events listen CompassEvent event userHeading event heading If direction is null this means the client does not have the compass sensor on their device and this scenario must be handled so as not to have exceptions in the execution of our app To expose this direction value you could have several approaches StreamBuilderProviderValueNotifieretc But this is not the main topic so just use your preferred one For the widget the plugin s example suggest us to use Transform rotate as follows Transform rotate angle direction math pi child Image asset assets compass jpg Of course this works but the angle changes are not smooth it just change from one angle value to the other without transition Which other option do we have AnimatedRotationAnimated version of Transform rotate which automatically transitions the child s rotation over a given duration whenever the given rotation changes But this widget requires a turn value to check against its previous value and then animate the transition of the rotation left to right if the value increases or right to left if the value decreases Transform the angle into turnsOk cool this is easy right Simply divide the direction to get a value based on where the user is pointing But now we will face the first BIG issue The compass will misbehave in two scenarios If the user s rotation it s from degree to If the user s rotation it s from degrees to This is the tricky partBecause we will need to do some math to just get the variation of the angle and then get the expected behavior Lets upgrade our listener function like this double turns double prevValue FlutterCompass events listen CompassEvent event double direction event heading direction direction lt direction direction double diff direction prevValue if diff abs gt if prevValue gt direction diff direction prevValue abs else diff prevValue direction abs diff diff turns diff prevValue direction We now have in turns the desire value just the change between the last and the new angle The widget should look like this AnimatedRotation turns turns duration const Duration milliseconds child const Icon Icons arrow upward outlined I hope this helps you and saves you some time	2022-06-09 04:13:48
