Local Server

Let's create a simple server:

server.js (Node.js)

import { createServer } from 'node:http';

createServer((_, res) => {
  res.writeHead(200, { 'Content-Type': 'application/json' });
  res.end(JSON.stringify({ name: 'Poku' }));
}).listen(4000, () => console.log('ready'));

server.js (Bun)

Bun.serve({
  port: 4000,
  fetch: () =>
    new Response(JSON.stringify({ name: 'Poku' }), {
      headers: { 'Content-Type': 'application/json' },
    }),
});

console.log('ready');

server.js (Deno)

Deno.serve({
  port: 4000,
  handler: () =>
    new Response(JSON.stringify({ name: 'Poku' }), {
      headers: { 'Content-Type': 'application/json' },
    }),
  onListen: () => console.log('ready'),
});

And now, test it:

test/server.test.js

import { assert, startService } from 'poku';

const server = await startService('server.js', {
  // Wait for the "ready" console output
  startAfter: 'ready',
});

// Use the requester you want
const res = await fetch('http://localhost:4000');
const data = await res.json();

assert.strictEqual(res.status, 200, 'Server is on');
assert.deepStrictEqual(data, { name: 'Poku' }, 'Poku is here');

server.end();

Need to test using a consistent session? 🍪

Just do it 🚀

Here's an example using Axios:

import { assert, startService } from 'poku';
import axios from 'axios';
import axiosCookieJarSupport from 'axios-cookiejar-support';
import { CookieJar } from 'tough-cookie';

const server = await startService('server.js');

axiosCookieJarSupport(axios);

const cookieJar = new CookieJar();

export const api = axios.create({
  withCredentials: true,
  jar: cookieJar,
});

const { data } = await api.get('http://localhost:4000');

assert.deepStrictEqual(data, { name: 'Poku' }, 'Poku is here');

tip

• Requester: You can use Axios, Node Fetch and everyone you want 💙
• Server: you can use every server you want, such as Express, Koa, etc.
• NextJS, ViteJS, nodemon and more? See bellow 👇🏻

You also can start your server using the startScript.

test/server.test.js

import { assert, startScript } from 'poku';

const server = await startScript('start', {
  // Wait for the "ready" console output
  startAfter: 'ready',
});

// Use the requester you want
const res = await fetch('http://localhost:4000');
const data = await res.json();

assert.strictEqual(res.status, 200, 'Server is on');
assert.deepStrictEqual(data, { name: 'Poku' }, 'Poku is here');

server.end();

package.json (Node.js)

{
  "script": {
    "start": "node server.js"
  }
}

package.json (Bun)

{
  "script": {
    "start": "bun server.js"
  }
}

deno.json (Deno)

{
  "tasks": {
    "start": "deno run --allow-net server.js"
  }
}

tip

Using startScript, you can execute NextJS, SvelteJS, nodemon and all the scripts you've always used 🐷
