PostgreSQL vs MySQL: Choosing the Right Database

Mon, 10 Aug 2020 00:00:00 +0000

Relational databases remain the backbone of most full stack applications. PostgreSQL and MySQL are the two most common choices-each excels in different scenarios.

PostgreSQL Strengths

PostgreSQL offers advanced types (JSONB, arrays), full-text search, robust concurrency (MVCC), and extensions like PostGIS. It is the default choice for complex queries, analytics-heavy apps, and strict data integrity.

MySQL Strengths

MySQL (and MariaDB) are widely hosted, familiar to many teams, and perform well for read-heavy web workloads. Managed offerings are plentiful and often slightly cheaper at small scale.

Building REST APIs with Node.js and Express

Sun, 22 Mar 2020 00:00:00 +0000

Express remains the most popular framework for building REST APIs in Node.js. It is minimal, unopinionated, and pairs well with middleware for auth, validation, and logging.

Project Setup

Initialize a project and install Express:

npm init -y
npm install express

Create a basic server with JSON body parsing:

const express = require('express');
const app = express();
app.use(express.json());

const items = [];

app.get('/api/items', (req, res) => res.json(items));

app.post('/api/items', (req, res) => {
  const item = { id: Date.now(), ...req.body };
  items.push(item);
  res.status(201).json(item);
});

app.listen(3000, () => console.log('API running on :3000'));
