Create Serverless APIs using Cloudflare Workers, Durable Objects & Wrangler

📦 Installation & Usage

With Apiker, you can create an API in only 3 lines of code

import { apiker, res } from "apiker";
const routes = { "/users/:id/hello": () => res("Hello World!") };

apiker.init({ routes, exports, objects: ["Common"] });

➡️ GET /users/my-user/hello

{ "message": "Hello World!" }

Check out the Getting Started page to begin.

Note: To run Apiker, you need a Cloudflare account with Durable Objects access.

📕 Examples

1. Route example

import { res, res_400 } from "apiker";

export const myRouteHandler = async ({
  request, // https://developers.cloudflare.com/workers/runtime-apis/request/
  body, // The body of your request, such as form params or plaintext, depending on request content-type
  headers, // Request headers. Response headers are located at `apiker.responseHeaders`
  matches, // Your query params and route parts
  state // The state method used to interact with permanent storage (check the examples below & docs for more info)
}) => {
  // If we want to allow POST only, we explicitly check for it :
  if(request.method !== "POST"){
     // returns 400 Bad Request error. You can also use `res("Invalid Method", 405)`
     // https://github.com/hodgef/apiker/blob/master/src/components/Response/Response.ts#L10
     return res_400();
  }

  // We'll return the request body passed, for example POST form parameters
  // `res` and `res_000` functions respond with JSON. To respond with raw text you can use `resRaw`
  // https://github.com/hodgef/apiker/blob/master/src/components/Response/Response.ts#L23
  return res({ body });
};

const routes = {
  "/users/myroute": myRouteHandler
};

2. State: Save value to Common object (shared by all visitors)

import { res } from "apiker";

export const example1_saveValueCommon = async ({ state }) => {
  // Using `state` with no parameters will default to the Common object
  const count = ((await state().get("count")) || 0) + 1;
  await state().put({ count });
  return res({ count });
};

➡️ GET /example1

{ "count": 1 }

3. State: Save value to a different object, and use one object instance per visitor

import { res } from "apiker";

export const example2_saveValueDiffObject = async ({ state }) => {
  const count = (await state("Example2").get("count") || 0) + 1;
  await state("Example2").put({ count });
  return res({ count });
};

// In index.js ...
apiker.init({
 ...
 objectStateMapping: {
    // One object instance per user IP
    Example2: OBMT.SIGNEDIP
  }
});

➡️ GET /example2

{ "count": 1 }

4. State: Use one object instance per route parameter value

import { res } from "apiker";

export const example3_instancePerRouteParam = async ({ state, matches }) => {
  // Get username from route (/example3/:username)
  const username = matches.params.username;
  const acceptedUsernames = ["bob", "rob", "todd"];

  if (acceptedUsernames.includes(username)) {
    const { name = username, count = 0 } = (await state("Example3").get("username")) || {};
    const payload = {
      username: {
        name,
        count: count + 1
      }
    };

    await state("Example3").put(payload);
    return res(payload);
  } else {
    return res({ acceptedUsernames });
  }
};


// In index.js ...
apiker.init({
 ...
 objectStateMapping: {
    // Mapped to the parameter `username` in the route
    Example3: "username"
  }
});

➡️ GET /example3/bob

{
    "username": {
        "name": "bob",
        "count": 1
    }
}
