Request Headers

---

getRequestHeaders

Get the request headers

import { eventHandler, getRequestHeaders } from "vinxi/http";

export default eventHandler(async (event) => {
  const headers = getRequestHeaders(event); 
});

Signature

export function getRequestHeaders(event: HTTPEvent): RequestHeaders;

---

export default eventHandler(async (event) => {
  const header = getRequestHeader(event, "content-type"); 
});

Signature

export function getRequestHeader(
  event: HTTPEvent,
  name: HTTPHeaderName,
): RequestHeaders[string];

Request Body

---

readBody

import { eventHandler, readBody } from "vinxi/http";

export default eventHandler(async (event) => {
  const body = await readBody(event); 
});

Signature

function readBody<
  T,
  Event extends H3Event<EventHandlerRequest> = H3Event<EventHandlerRequest>,
  _T = InferEventInput<"body", Event, T>,
>(event: Event, options?: { strict?: boolean }): Promise<_T>;

---

readFormData

Constructs a FormData object from an event, after converting it to a a web request.

import { eventHandler, readFormData } from "vinxi/http";

export default eventHandler(async (event) => {
  const formData = await readFormData(event); 
  const email = formData.get("email");
  const password = formData.get("password");
});

Signature

export function readFormData(event: HTTPEvent): Promise<FormData>;

---

readMultipartFormData

Tries to read and parse the body of an HTTPEvent as a multipart form.

import { eventHandler, readMultipartFormData } from "vinxi/http";

export default eventHandler(async (event) => {
  const data = await readMultipartFormData(event); 
});

Signature

type MultiPartData = {
  data: Buffer;
  name?: string;
  filename?: string;
  type?: string;
};

export function readMultipartFormData(
  event: HTTPEvent,
): Promise<MultiPartData[] | undefined>;

---

readValidatedBody

Tries to read the request body via readBody, then uses the provided validation function and either throws a validation error or returns the result.

Using zod

import { eventHandler, readValidatedBody } from "vinxi/http";
import { z } from "zod";

const objectSchema = z.object({
  email: z.string(),
  password: z.string(),
});
//
export default eventHandler(async (event) => {
  const body = await readValidatedBody(event, objectSchema.safeParse);
});

Using custom validation function

import { eventHandler, readValidatedBody } from "vinxi/http";

//
export default eventHandler(async (event) => {
  // With a custom validation function
  const body = await readValidatedBody(event, (body) => {
    return typeof body === "object" && body !== null;
  });
});

Signature

export function readValidatedBody<
  T,
  Event extends HTTPEvent = HTTPEvent,
  _T = InferEventInput<"body", Event, T>,
>(event: Event, validate: ValidateFunction<_T>): Promise<_T>;

---

readRawBody

Reads body of the request and returns encoded raw string (default), or Buffer if encoding is falsy.

import { eventHandler, readRawBody } from "vinxi/http";

export default eventHandler(async (event) => {
  const body = await readRawBody(event, "utf-8"); 
});

Signature

function readRawBody<E extends Encoding = "utf8">(
  event: HTTPEvent,
  encoding?: E,
): E extends false ? Promise<Buffer | undefined> : Promise<string | undefined>;

---

getRequestWebStream

  event: HTTPEvent,
): ReadableStream | undefined;

---

>(event: Event): _T;

---

getValidatedQuery

Get the validated query

import { eventHandler, getValidatedQuery } from "vinxi/http";

export default eventHandler(async (event) => {
