## Usage
2024-04-14 16:14:02 +00:00
`@push.rocks/smartrouter` provides a versatile routing solution for websites, leveraging modern Web APIs to manipulate browser history and handle URL paths intelligently. Below are examples demonstrating how to use `@push.rocks/smartrouter` effectively in a TypeScript project, taking advantage of ESM syntax.
### Basic Setup
First, ensure you've installed the package as described in the Install section above. Next, import `SmartRouter` from `@push.rocks/smartrouter` in your application's entry point or any module where routing is required.
```typescript
import { SmartRouter } from '@push.rocks/smartrouter';
```
### Initialize the Router
Create an instance of `SmartRouter` and optionally provide configuration options. If your application requires debugging information, `debug` can be set to `true`.
```typescript
const router = new SmartRouter({
debug: true, // Enables debugging. Optional and false by default.
});
```
### Define Routes
Define your application routes using the `on` method, which takes a URL pattern and a handler function. The handler function will be called when the application navigates to a URL that matches the pattern.
```typescript
router.on('/home', async (routeInfo) => {
console.log('Home route accessed', routeInfo);
// Handle the home route
// You can load a page component, change document title, etc.
});
router.on('/about', async (routeInfo) => {
console.log('About route accessed', routeInfo);
// Handle the about route
});
```
### Path Parameters
`@push.rocks/smartrouter` supports dynamic path parameters. Define path parameters within your route strings using the `:` prefix, and access their values from the `routeInfo.params` object in your handler function.
```typescript
router.on('/user/:userId', async (routeInfo) => {
console.log(`User Profile for ID: ${routeInfo.params.userId}`, routeInfo);
// Load and display user profile based on userId
});
```
### Query Parameters
Query parameters can be accessed through the `routeInfo.queryParams` object, making it easy to handle complex routing scenarios with optional parameters.
```typescript
router.on('/search', async (routeInfo) => {
console.log('Search Query:', routeInfo.queryParams.query);
// Perform a search operation using the provided query parameter
});
```
### Programmatic Navigation
Navigate programmatically using the `pushUrl` method. This method allows you to change the URL without reloading the page, and optionally pass state information.
```typescript
// Navigate to the about page
router.pushUrl('/about');
// Navigate to a user profile with URL parameters
router.pushUrl('/user/12345');
```
### Managing Query Parameters
`@push.rocks/smartrouter` provides methods for managing URL query parameters, enabling dynamic URL manipulation for filter settings, pagination, and other use cases.
```typescript
// Set a query parameter
router.queryParams.setQueryParam('key', 'value');
// Get a query parameter
const value = router.queryParams.getQueryParam('key');
// Delete a query parameter
router.queryParams.deleteQueryParam('key');
```
### Selection Dimensions
`@push.rocks/smartrouter` introduces the concept of selection dimensions, allowing you to manage stateful selections across routes. This is especially useful for complex navigation flows that depend on prior selections.
```typescript
await router.createSelectionDimension({
routeArg: '/select/:option',
keyArg: 'mySelection',
options: [
{
key: 'option1',
detail: { /* some data */ },
action: async () => { /* action for option1 */ }
},
{
key: 'option2',
detail: { /* some data */ },
action: async () => { /* action for option2 */ }
}
]
});
// Navigate to a selection option
router.pushUrl('/select/option1');
```
This module enables complex routing scenarios, simplifying the handling of navigational logic in modern web applications. By leveraging `@push.rocks/smartrouter`, developers can implement detailed routing mechanisms, manipulate browser history thoughtfully, and maintain cleaner URL structures, enhancing the user experience and making web apps more accessible.
