Serverless Driver for JavaScript

3 posts · May 2021 – Sep 2022

What this trail covers

PlanetScale offers a serverless driver for JavaScript, enabling direct HTTP connections to databases from environments like Cloudflare Workers, Vercel Edge Functions, and Netlify Edge Functions. This integration leverages a new HTTP API and global routing infrastructure, similar to a CDN, to reduce latency and improve connection reliability and performance. It supports standard SQL operations and helps prevent SQL injection. The driver works in any environment supporting the Fetch API.

All PlanetScale trails
  1. Using the PlanetScale serverless driver with AWS Lambda functionsThis post introduces the PlanetScale serverless driver for JavaScript, detailing its setup and usage with AWS Lambda and API Gateway. It demonstrates how to create a database, enable the beta feature, configure environment variables, and implement basic CRUD operations (SELECT, INSERT) via HTTP requests. The guide covers project initialization, package installation, and the deployment process to AWS Lambda, along with setting up API Gateway routes.
  2. Introducing the PlanetScale serverless driver for JavaScriptIntroduces a new Fetch API-compatible JavaScript driver for PlanetScale, enabling direct HTTP connections to databases from serverless and edge environments. This is backed by new HTTP API and global routing infrastructure that provides benefits like modern TLS, connection multiplexing, protocol compression, and reduced latency through edge routing. The post provides installation instructions, connection configuration, and example usage for executing SQL commands and parameterized queries.
  3. Serverless finally has a databaseThis post introduces the concept of serverless databases and argues that PlanetScale is the solution for serverless developers. It contrasts the advancements in application development (like Serverless and Rails) with the relative stagnation in database technology for typical developers. The post highlights PlanetScale's vision of a data platform designed from scratch for modern developers, offering features like non-blocking schema changes, deploy requests, and database branches, all within a pay-as-you-grow model.
