`http_response_helpers`

Simple helper functions to create Fetch API Response’s.

Usage

There’s a simple function for each HTTP status type. See the deno docs for the functions and their status code. Most functions take a body argument and the response init object. The headers and other information can be specified in the response init object.

Most response helpers will have the following functions.

ok(body, init) - Only automatically sets the status code and status text.
ok.json(body, init) - Automatically sets status and the content type to application/json

Simple

import { serve } from "https://deno.land/std@0.142.0/http/server.ts";

import { ok } from "https://deno.land/x/http_response_helpers/mod.ts";

serve((req: Request) => {
  return ok("Hello world");
});

With custom headers

import { serve } from "https://deno.land/std@0.142.0/http/server.ts";

import { ok } from "https://deno.land/x/http_response_helpers/mod.ts";

serve((req: Request) => {
  return ok("Hello world", {
    headers: {
      "X-Custom-Header": "custom header value",
    },
  });
});

JSON

Deserializes the body object supplied and sets the Content-Type to application/json.

import { serve } from "https://deno.land/std@0.142.0/http/server.ts";

import { ok } from "https://deno.land/x/http_response_helpers/mod.ts";

serve((req: Request) => {
  const body = {
    message: "Hello world",
  };
  return ok.json(body);
});

With custom headers

import { serve } from "https://deno.land/std@0.142.0/http/server.ts";

import { ok } from "https://deno.land/x/http_response_helpers/mod.ts";

serve((req: Request) => {
  const body = {
    message: "Hello world",
  };
  return ok.json(body, {
    headers: {
      "X-Custom-Header": "custom header value",
    },
  });
});
