Task and Lifecycle

Snippet Purpose
q-useTask adds useTask$(): it registers a hook to be executed upon component creation, it will run at least once either in the server or in the browser
q-useTask-with-track adds useTask$(): it re-run a task when a component state changes.
q-useVisibleTask adds useVisibleTask$(): it that runs run only on the browser and after rendering

Snippet Purpose
q-createContext This creates a serializable ID for the context. Make sure that this id is unique within your application
q-useContextProvider At a parent component call this method to publish the context value. All children (and grandchildren) that are descendants of this component will be able to retrieve the context.
q-useContext To retrieve the context and use it in any component.

Snippet Purpose
q-projection Projection is a way of passing content to a child component that in turn controls where the content is rendered. Projection is a collaboration between the parent and child component. The parent component decides what is the content that needs to be rendered, child component decides where and if the content should be rendered.
q-projection-named-slot In simple cases, projection allows content from the parent component to be projected into the child component. In more complex cases there may be more than one content slot that needs to be projected. Having multiple content slots is achieved by naming them.

Snippet Purpose
q-useStyles$ Qwik is responsible for loading the style information when a component is mounted. Use useStyles$() to tell Qwik which style should be loaded.
q-useStylesScoped$ Use useStylesScoped$() to load and scope the style to a specific component only.

$ Optimizer

Snippet Purpose
q-$-hook $() function hook
q-lazy-loading-constants For the application to be resumable it needs to have lots of entry points. For example, clicking on button A is a different entry point than clicking on button B. When we implement an application we don't usually think about entry points and so we typically end up with just one entry point or the main() function. The Optimizer does its job by looking for functions that end in $ character. For example, the Optimizer will transform a call to component$() into an entry point. Notice that the name of the function doesn't matter only that it ends with the $. Every time you see $ you should think, there is a lazy-loaded boundary here. The implication is that the lazy-loaded content may require lazy-loading and hence can't be accessed synchronously. While the Optimizer can serialize any data that Qwik can serialize, it has special handling for closures. Closures are functions that are created inside of other functions and that may capture variables in the lexical scope. The ability to serialize closures is a key property that makes Qwik resumable. Without closure serialization, it would be difficult to have resumable applications.
q-lazy-loading-closures A closure can be converted into a lazy-loaded reference using the $() function. This generates a QRL<Function> type. A QRL is a lazy-loadable reference of the closure. In our case, we have extracted the closure associated with the onInput event into the component body. Because it is no longer inlined we need to change how the JSX refers to it from onInput$ to onInputQrl. Notice that our closure closes over the store that is captured by the Optimizer and then restored as needed.

Composing New APIs

The powerful, part of Optimizer is that you can create your own APIs with $ suffix.

Snippet Purpose
q-create-api-$ This method knows how to take a QRL and execute it after a certain delay. The key part here is that the QRL.invoke() method is called when the delay is ready and is therefore lazy.
q-composing-use-hook Hooks are a way to abstract common logic away from the components that use it. They are a way to share logic between components. While Qwik provides many hooks, there will always be one that is not provided out of the box. This tutorial will show you how to create your own hook. n this example, the registering of mousemove events is something that could be shared between multiple components. Refactor the code by pulling out the code before JSX into its own useMousePosition() function.

Qwik City Snippets


Routing is a way to map public URLs for a site to specific components declared in your application.

Qwik City uses directory-based routing. This means that the structure of your routes directory drives the public-facing URLs that the user will see for your application. However, it differs slightly from traditional file-based routing, which we will discuss shortly.

Snippet Purpose
qc-useLocation Retrieve the Route Parameter from the URL
qc-404-not-found At times it is necessary to respond with HTTP status codes other than 200. In such cases, response handler is the place to determine what status code should be returned.

When implementing routes, different routes usually share a common header, footer, and menu system. We call the common parts a layout.

The developer could extract all of these into <Header>, <Footer>, and <Menu> components and manually add them to each page component, but that is repetitive and error-prone. Instead, we can use layouts to automatically reuse common parts.

Snippet Purpose
qc-layout Add sample layout
qc-layout-structure Add sample layout structure
qc-nested-layout Add sample nested layout
qc-nested-layout-structure Add sample nested layout structure
qc-grouped-layout-structure Add sample group layout structure
qc-named-layout-structure Add sample named layout structure
qc-top-layout-structure Add sample top layout structure
qc-menu Add sample menu
qc-header Add sample header
qc-footer Add sample footer

Each route has the ability to add HTTP request and response handlers, allowing for developers to retrieve and modify data. The handlers can also be used by endpoints, which only respond with data rather than a page's HTML.

This feature enables you to handle any request event, have side effects on the request pipeline, just before you render the component and respond with custom content. It is available to pages, layouts and endpoint routes, but not on regular components.

Snippet Purpose
qc-onGet onGet API route
qc-onGet-sample onGet API route sample
qc-onGet-in-component onGet API route in a component
qc-onPost onPost API route
qc-onPut onPut API route
qc-onPut-sample onPut API route sample
qc-onPatch onPatch API route
qc-onDelete onDelete API route
qc-redirect redirect route
qc-redirect-sample redirect route sample
qc-useEndpoint add useEndpoint declaration

Authoring Content

Snippet Purpose
q-component Add mdx content
qc-component-import Importing other components. You can build complex views by composing multiple components within each other. To do that import other components into your index.tsx file.
qc-mdx Add mdx content
qc-mdx-with-component Add mdx with qwik component
qc-mdx-disable-default-plugins Disabling default MDX plugins included.
qc-menu-structure Adding menu structure
qc-useContent Retrieve menu structure
qc-use-content-menu-in-layout While useContent() can be invoked from any component that is part of the current route. It is typically used in a layout component (or a component used by layout) to render the menu.

Snippet Purpose
qc-qwikify-react-component Qwikify a react component
qc-qwikify-react-event Qwikify React Event. Events in React are handled by passing a function as a property to the component.
qc-qwikify-eagerness Qwikify a react component with eagerness
qc-client-load Add client load interactivity
qc-client-idle Add client idle interactivity
qc-client-visible Add client visible interactivity
qc-client-hover Add client hover interactivity

qc-partytown-sample Add partytown sample code
qc-tailwind Add tailwind css

Snippet Purpose
qc-prefetch-event Add prefetch event. props: [bundles,symbols, links]
qc-prefetch-service-worker Add prefetch service worker

Static Site Generation

Static Site Generation, or commonly referred to as "SSG", is the process of pre-rendering site webpages into static HTML files. The benefit is that when a visitor requests the webpage, the response is a pre-generated HTML file (a static file), and doesn't require the webpage's HTML to "rebuild" on the visitors browser, or dynamically created by your server.

Snippet Purpose
qc-ssg Add static side generation
qc-ssg-scripts Add static side generation scripts
qc-ssg-dynamic-routes Add static side generation dynamic routes

HTML places the

tag as the first element within (at the very top of the HTML content). The section is not something that your route component renders directly, yet you still need to control its content. This can be achieved by exporting a head property (or function) from your page component.
Snippet Purpose
qc-static-document-head Add static document head
qc-dynamic-document-head Add dynamic document head
qc-resolved-document-head Add resolved document head
