海外TECH	DEV Community	Svelte for Beginners: A Beginner's Guide to Building Web Applications	https://dev.to/rafael_abuawad/svelte-for-beginners-a-beginners-guide-to-building-web-applications-3o5j	Svelte for Beginners A Beginner x s Guide to Building Web ApplicationsSvelte is a popular JavaScript framework for building web applications Thanks to some tricks it is lightweight and easy to use making it a great option for beginners In this blog post we ll take a look at how to set up Svelte and give code samples for working with forms reactive states and stores Setting up SvelteTo get started you ll need to have Node js installed on your machine Once you have Node js installed you can use Vite to create a new Svelte project npm create vite latest my svelte app template svelteThis will create a new directory called my svelte app and initialize it with the Svelte template Next navigate to the new directory and install the necessary dependencies cd my svelte appnpm installNow that you have your project set up you can start the development server using the following command npm run devThis will start a development server and open your project in a web browser You should see a Vite Svelte message on the page on top of a count button if you press that button you will see how the count increases we will learn how to do that ourselves in the following section Open that directory on a code editor of your choice you can see an App svelte file inside the src folder remove all of its contents Also delete the src lib folder we will not use it in this case Working with Reactive StateSvelte uses a reactive system to automatically update the DOM when the state of a component changes In the following example we ll create a simple counter that increments and decreases a value when clicking buttons Open the App svelte file and type the following lt script gt let count function increment count function decrement count lt script gt lt button on click decrement gt lt button gt lt span gt count lt span gt lt button on click increment gt lt button gt In this example we created two buttons one to increment the count and one to decrease the count The on click directive is used to attach click events to the buttons which call the increment and decrement functions respectively The count variable is used to store the current value of the counter which is displayed in a span element using curly braces When the increment or decrement function is called the value of the count variable is updated and Svelte s reactive system automatically updates the span element to reflect the new value Working with formsSvelte makes it easy to work with forms and inputs In the following example we ll create a simple form with text input and a submit button The form will have a submit event that will output the text input s value to the console when the button is clicked Remove all of the contents on App svelte and write lt script gt let name function handleSubmit console log name lt script gt lt form on submit preventDefault handleSubmit gt lt input type text bind value name gt lt button type submit gt Submit lt button gt lt form gt In this example we are using the bind value directive to bind the value of the text input to a variable called name The on submit preventDefault directive is used to attach a submit event to the form which calls the handleSubmit function when the button is clicked The preventDefault modifier is used to prevent the default behavior of the form which is to refresh the page Working with StoresSvelte also allows you to create global stores which can be used to share states across multiple components In the following example we ll create a store for a user s name and age and use it in multiple components Create a folder inside src called stores and inside that folder create a main js this will be our main store for this application you can have multiple stores that can do multiple things but for the sake of simplicity we will keep this short stores main jsimport writable from svelte store export const name writable export const age writable After that create another folder called components we will create two Svelte files one called ComponentA svelte and the other will be called ComponentB svelte you can call the components whatever you like In the first component we are going to get the name from the store and updated it to something else on that component To subscribe to a store value you just need to prepend to each variable lt Component A gt lt script gt import name from stores main js lt script gt lt form gt lt label for name gt Name lt label gt lt input id name type text bind value name gt lt form gt Now in the second component we are going to get the age from the store and updated it to something else on that component lt Component B gt lt script gt import age from stores main js lt script gt lt form gt lt label for age gt Age lt label gt lt input id age type number bind value age gt lt form gt After that we can go back to our App svelte file remove all of its contents and import the two components lt script gt import ComponentA from components ComponentA svelte import ComponentB from components ComponentB svelte import name age from stores main js lt script gt lt ComponentA gt lt ComponentB gt lt h gt Hello I m name and I m age years old lt h gt In this example we have created two stores for a user s name and age in the stores main js file We then import and use these stores in two different components We use the bind value directive to bind the input value to the store As you can see the value of the store is reactive and will change if the input is changed In summary Svelte is a powerful and easy to use JavaScript framework for building web applications It allows you to work with forms reactive states and stores in a simple and intuitive way This guide should give you a good starting point for building your own Svelte applications	2023-01-18 21:48:14
