海外TECH	DEV Community	createFactory in React. 🏭 important function in React	https://dev.to/diwakarkashyap/createfactory-in-react-important-function-in-react-1gn7	createFactory in React important function in ReactTo create a factory in React you can use the createFactory function from the React library The createFactory function takes a component class as its argument and returns a factory function The factory function can then be used to create new instances of the component class Here is an example of how to create a factory in React import React createFactory from react const MyComponent name gt return lt div gt Hello name lt div gt const MyFactory createFactory MyComponent export default function App return lt MyFactory name John Doe gt In this example we first create a component class called MyComponent The MyComponent class takes a name prop as its argument and renders a greeting to the user Next we use the createFactory function to create a factory function for the MyComponent class The factory function is called MyFactory Finally we use the MyFactory function to create a new instance of the MyComponent class and render it to the DOM The factory pattern is a useful design pattern in React when you need to create different objects based on different conditions or inputs For example you could use the factory pattern to create different types of buttons or to create different types of forms The factory pattern can also be used to decouple the object creation logic from the client code This can make your code more modular and easier to maintain Thank you for reading I encourage you to follow me on Twitter where I regularly share content about JavaScript and React as well as contribute to open source projects I am currently seeking a remote job or internship Twitter GitHub Portfolio	2023-08-12 13:19:39
海外TECH	DEV Community	Creating a Custom URL Protocol in .NET	https://dev.to/jamiemcmanus/creating-a-custom-url-protocol-in-net-322h	Creating a Custom URL Protocol in NETYou open a Teams link and it prompts you to open the Teams Desktop Application and you sit back and wonder how this works Well wonder no more This process is possible because of URL protocols similar to how Windows sets the default web browser or the default email app You have probably seen it in actions a few times from apps like Teams or Zoom Windows has a few of these built in but we can create our own custom protocols too You can create these by manually adding a Reg Key but we ll do this via NET We ll create a simple app and a custom protocol that will open this app when a user clicks on a URL with the protocol Lets go SetupLets start with creating a desktop application for simplicity I ve chosen a WPF app Open Visual Studio with Administrator privilege s I ll explain later and create a new WPF project App StartupIn the App xaml cs file create a new method called RegisterProtocol We ll run this on startup to create our protocol We ll need to do check if the protocol exists and if not then create it We set the name of our protocol and assign to a variable string customProtocol CustomProtocol Then add we check if a Registry Key exists for this value RegistryKey key Registry ClassesRoot OpenSubKey customProtocol if key null If the key is null then we will have to create one if key null key Registry ClassesRoot CreateSubKey customProtocol key SetValue string Empty URL customProtocol key SetValue URL Protocol string Empty key key CreateSubKey shell open command key SetValue string Empty applicationPath key Close Now to explain it a bit key Registry ClassesRoot CreateSubKey customProtocol This line creates a new subkey in the HKEY CLASSES ROOT registry This is where file associations and protocol handlers are registered key SetValue string Empty URL customProtocol This line sets a value for the subkey we just created The value s name is an empty string indicating the default value for the key and the value s data is a string that specifies the type of URL and the custom protocol name key SetValue URL Protocol string Empty This line sets a value named URL Protocol within the same subkey key key CreateSubKey shell open command This line creates a new subkey within our key The subkey is named shell open command This is where you specify the command to be executed when a URL matching our protocol is opened key SetValue string Empty applicationPath This line sets the default value for the shell command key we just created The data is the filepath to the EXE for our application and represents any parameters sent key Close We simply close the key to finish We now have one last thing before the key can be registered We have to make sure the application has the correct privilege s to edit the registry In your app manifest file add one if you dont have one Add the below lt requestedPrivileges xmlns urn schemas microsoft com asm v gt lt requestedExecutionLevel level requireAdministrator gt lt requestedPrivileges gt This will make the application ask the user for admin the privilege s that we need to create the key GUINext up we ll edit the application to display any arguments that are passed to the app when opened via the custom protocol We don t need to do this part but it will show you that any parameters you sent are indeed working In your MainWindow xaml cs add the below string to display the arguments passed in public string ArgumentsText get return argumentsTextBlock Text set argumentsTextBlock Text value And within the MainWindow xaml file add a textblock to display the string lt TextBlock x Name argumentsTextBlock Margin gt Next we need to edit the app xaml cs to pass the arguments into the MainWindow Edit the OnStartup like so protected override void OnStartup StartupEventArgs e base OnStartup e RegisterProtocol MainWindow mainWindow new MainWindow if e Args Length gt string arguments string Join e Args mainWindow ArgumentsText Arguments arguments else mainWindow ArgumentsText No arguments provided mainWindow Show We first call our RegisterProtocol method and then check for any arguments passed in on startup before manually creating our main window Now you can publish the application and click the EXE to run it You should see something like the below image This is what we expect there are no parameters passed when clicking the EXE WebNext we re going to create a simple HTML file to simulate opening our protocol from the web lt DOCTYPE html gt lt html gt lt head gt lt title gt Custom Protocol Test lt title gt lt head gt lt body gt lt p gt Click the link below to test your custom protocol lt p gt lt a href CustomProtocol myargument gt Test Custom Protocol lt a gt lt body gt lt html gt Like I said pretty simple The value for the href is the name of your protocol followed by along with any parameters you want to pass I am passing in the string myargument In ActionLets open up the file in browser and try it out Click on the link and you should be greeted with a prompt like the below Perfect Click Open and our application should open as expected Finishing UpThere we have it its not a glamourous example but who said programming would be eh You can see the sample application here JamieMcManus CustomProtocolAppExample Sample Project for a Registering a Custom URL Protocol Got any improvements Then feel free to comment below And if you re feeling generous you can buy me a coffee with the link below and yes its all for coffee I drink a copious amount of it while writing	2023-08-12 13:11:11
