Atomic API

WARNING: This is Work-In-Progress!

Use atomic-router as your router for Node.js backend

Install

npm install atomic-router atomic-api

Usage

1. Create API controls

// @/shared/api
import { createApiControls } from "atomic-api";

// Returns { $method, $response } stores
export const apiControls = createApiControls();

2. Create API route

// @/routes/post
import { createApiRoute } from "atomic-api";

import { apiControls } from "@/shared/api";

export type PostParams = {
  postId: string;
};

export const post = createApiRoute({
  controls: apiControls,
  api: {
    GET: ({ params }) => {
      return {
        id: params.postId,
        title: "Some Post",
      };
    },
  },
});

// `createApiRoute` returns this
post.route; // Route created by atomic-router
post.api.GET; // Effect<RouteParamsAndQuery<PostParams>, ...>

3. Create a router

// @/app/router
import { createHistoryRouter } from "atomic-router";

import { post } from "@/routes/post";

export const routes = [{ path: "/posts/:postId", route: post.route }];

export const router = createHistoryRouter({
  routes,
});

4. Create a server

// @/app/server
import { createHttpServer } from "atomic-api";

import { router } from "@/app/router";
import { apiControls } from "@/shared/api";

export const server = createHttpServer({
  router,
  controls: apiControls,
});

server.listen(3002);

How does it work?

1. createHttpServer starts a server (via http.createServer)
2. On each request:
   2.1. Trigger fork and creates a new scope 2.2. Store req.method in apiControls.$method 2.3. Create history instance and pushes req.url to it 2.4. Trigger router.setHistory with a passed scope 2.5. Router opens matched route 2.6. Check apiControls.$method and open matching sub-route (created by chainRoute) 2.7. Trigger effect and wait until it's finished 2.8. effect.doneData writes its response to apiControls.$response 2.9. Trigger res.send with apiControls.$response data

TODO:

• [ ] Actually send response
• [ ] Pass req/res instance to effects
• [ ] Redirects
