Request Composables
The request composables provide various functions to interact with the incoming HTTP request in a Wooks HTTP application. These functions allow you to access different aspects of the request, such as headers, query parameters, cookies, authorization headers, and more.
Content
Raw Request Instance
To get a reference to the raw request instance, you can use the useRequest
composable function. However, in most cases, you won't need to directly access the raw request instance unless you're developing a new feature or require low-level control over the request.
import { useRequest } from '@wooksjs/event-http'
// cjs:
// const { useRequest } = require('@wooksjs/event-http')
app.get('/test', () => {
const { rawRequest } = useRequest()
// Access the raw request instance if needed
})
URI Parameters
URI parameters are automatically parsed by the router and are covered in the Retrieving URI Parameters section.
Query Parameters
The useSearchParams
composable provides three functions for working with query parameters:
urlSearchParams()
— returns an instance ofWooksURLSearchParams
, which extends the standardURLSearchParams
with atoJson
method that returns a JSON object of the query parameters.jsonSearchParams()
— is a shortcut forurlSearchParams().toJson()
, returning the query parameters as a JSON object.rawSearchParams()
— returns the raw search parameter string, such as?param1=value&...
.
import { useSearchParams } from '@wooksjs/event-http'
app.get('hello', () => {
const { urlSearchParams, jsonSearchParams, rawSearchParams } =
useSearchParams()
// curl http://localhost:3000/hello?name=World
console.log(jsonSearchParams()) // { name: 'World' }
console.log(rawSearchParams()) // ?name=World
return `Hello ${urlSearchParams().get('name')}!`
})
Example usage with cURL:
curl http://localhost:3000/hello?name=World
# Hello World!
Method and Headers
The useRequest
composable provides additional shortcuts for accessing useful data related to the request, such as the URL, method, headers, and the raw request body.
import { useRequest } from '@wooksjs/event-http'
app.get('/test', async () => {
const {
url, // Request URL (string)
method, // Request method (string)
headers, // Request headers (object)
rawBody, // Request body (() => Promise<Buffer>)
} = useRequest()
const body = await rawBody() // Body as a Buffer
})
Cookies
Cookies are not automatically parsed unless requested. The useCookies
composable function provides a cookie getter and access to the raw cookies string.
import { useCookies } from '@wooksjs/event-http'
app.get('/test', async () => {
const {
rawCookies, // Raw "cookie" from headers (string | undefined)
getCookie, // Cookie getter ((name) => string | null)
} = useCookies()
console.log(getCookie('session'))
// Prints the value of the cookie with the name "session"
})
Authorization
The useAuthorization
function provides helpers for working with authorization headers:
import { useAuthorization } from '@wooksjs/event-http'
app.get('/test', async () => {
const {
authorization, // The raw value of the "authorization" header (string)
authType, // The authentication type (Bearer/Basic) (string)
authRawCredentials, // The authentication credentials that follow the auth type (string)
isBasic, // Returns true if authType === 'Basic' (() => boolean)
isBearer, // Returns true if authType === 'Bearer' (() => boolean)
basicCredentials, // Parsed basic auth credentials (() => { username: string, password: string })
} = useAuthorization()
if (isBasic()) {
const { username, password } = basicCredentials()
console.log({ username, password })
} else if (isBearer()) {
const token = authRawCredentials
console.log({ token })
} else {
// Unknown or empty authorization header
}
})
Body Parser
The implementation of the body parser is isolated into a separate package called @wooksjs/http-body
. For more details on using the body parser, refer to the Body Parser section.
