MySQL / MariaDB

MySQL/MariaDB for relational data.

Stack Components

DBMySQL 8.4

Poolmysql2 3

MigratePrisma 5

Why

Widely supported, fast reads, replication. PostgreSQL is used by nearly 50% of professional developers, making it the most popular database (Stack Overflow 2024).

SQLite powers 1 trillion+ active databases (every iOS/Android device), and DuckDB emerged as the fastest OLAP engine for analytics, 5-10x faster than ClickHouse for single-node queries.

When

Use for LAMP/LEMP stacks. Avoid for complex analytics (use PG).

How

1. docker run mysql:8.4 2. Create database 3. Run migrations 4. Connect with mysql2 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

CREATE TABLE users (id BIGINT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255)) INSERT INTO users (name) VALUES ('Alice') // MySQL / MariaDB — usage example import { MySQLMariaDB } from "mysql-mariadb"; const result = await mysqlmariadb({ input: "data" }); console.log(result);

Common Problems

⚠Charset — use utf8mb4 for emoji
⚠Replication lag — use semi-sync for durability
⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

✓Use InnoDB for transactions
✓Enable slow query log
✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is MySQL / MariaDB and what projects is it for?

MySQL/MariaDB for relational data. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with MySQL / MariaDB in 10 minutes?

Two steps: (1) docker run mysql:8.4; (2) Create database. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with MySQL / MariaDB and how do I avoid it?

The most common pitfall is: Charset — use utf8mb4 for emoji. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for MySQL / MariaDB?

Best practices for MySQL / MariaDB include: Use InnoDB for transactions; Enable slow query log; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use InnoDB for transactions" — should be set up at project init to avoid costly rework later.

When should I NOT choose MySQL / MariaDB?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). MySQL / MariaDB shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
