Quick Start

const { KoaApplication, Router, success } = require("@axiosleo/koapp");

const handle = async (ctx) => {
  success({
    message: "Hello World!",
  });
};

const router = new Router("/test", {
  method: "any",
  handlers: [handle],
});

const app = new KoaApplication({
  port: 8088,
  listen_host: "localhost", // 0.0.0.0 for public access
  routers: [router],
});
app.start();

// open http://localhost:8088/test

More Examples

Validation

see validatorjs for more rule examples
see Router examples for more usage: tests/bootstrap.js

const { Router } = require("@axiosleo/koapp");

const router = new Router("/test", {
  method: "any",
  validator: {
    // url params, like `/test/{:id}`, the 'id' is required and must be an integer
    params: {
      id: "required|integer",
    },
    query: {
      name: "required|string",
    },
    body: {
      age: "required|integer",
    }
  }
  handlers: [],
});

const { _foreach, _sleep } = require("@axiosleo/cli-tool/src/helper/cmd");

const test = async (context) => {
  await _foreach(["0", "1", "2", "3"], async (item, index) => {
    context.koa.sse.send({ data: { item, index } });
    await _sleep(1000);
  });
  context.koa.sse.end();
};

const { KoaSSEMiddleware } = require("@axiosleo/koapp");

root.any("/sse", async (context) => {
  const func = KoaSSEMiddleware();
  await func(context.koa, async () => {});
  context.koa.sse.send({ data: "hello, world!" });
  process.nextTick(test, context);
});
