    Environment variables in Node.js look trivial until they bite you: everything is a string, "false" is truthy, and every child process you spawn inherits your secrets. I just published a complete guide. Here's the short version ๐Ÿงต
    Infographic titled โ€œNode.js Environment Variables: Simple until they bite you.โ€ On a dark, neon green and cyan tech-style background, five panels explain key pitfalls and best practices: (1) everything in process.env is a string, for example PORT becomes "3000"; (2) the โ€œfalseโ€ trap, where "false" is still truthy in JavaScript; (3) built-in .env loading in modern Node.js with --env-file; (4) layered .env files, where later files win but OS environment variables still override; and (5) security risks, showing child processes inheriting secrets by default. A green banner at the bottom highlights the best practice: use one validated config module, fail fast, and keep secrets out of environment variables in production. The full guide URL appears at the bottom: nodejsdesignpatterns.com/blog/nodejs-environment-variables.

    Node.js 26 shipped this week ๐ŸŽ‰ My birthday is close, so I'm officially calling it an early birthday present from the Node.js team ๐Ÿ˜‚ It doesn't look flashy at first, but the additions are genuinely useful in everyday code. I wrote a code-heavy tour, here's what stood out ๐Ÿงต

    New post: Writing middlewares for #Rust #Lambda functions ๐Ÿฆ€ The #AWS Lambda Rust runtime already ships a middleware engine: tower. Almost nobody is using it. Deep dive + a complete #DynamoDB rate limiter you can steal: loige.co/writing-middleโ€ฆ
