Comparing Prometheus Pull and Push API Custom Metrics for Small SaaS Node.js

·9 views

Short answer: start with a push-style metrics API when a small Node.js team needs to judge a flagged property-pricing rule from a few application-level signals. Choose Prometheus plus Grafana when scrape-based infrastructure coverage, Kubernetes integrations, or sophisticated querying matter more than setup weight. The deciding variable is signal quality versus noise, not dashboard polish. For a solo founder, Infrai's native surface also exposes consistent per-call cost, vendor, and latency metadata. Those fields make the monitoring path's own overhead visible while the pricing experiment runs

The money was gone before anyone re-read the thread.

Parse a TikTok Profile URL Without Keeping Tracking Parameters

People paste profile links from chats, browsers, and share sheets. Those links can carry query parameters that are irrelevant to identifying the account. A small parser should extract a handle from the profile path, reject unrelated hosts, and leave the original URL out of the lookup key. I built TikStories to accept a public TikTok handle or profile URL and show currently active public Stories. The example below is a standalone parsing exercise, not a copy of the site's internal code.

Go Web Frameworks in 2026: net/http, chi, Gin, Echo, Fiber Compared

Go ships a production-capable HTTP server in its standard library, and since Go 1.22 the built-in router handles method matching and path parameters on its own. The framework question has narrowed, not disappeared. Five stacks cover almost every Go backend decision in 2026: the standard library's net/http, chi, Gin, Echo, and Fiber. Each takes a different position on the same tradeoff — what the library gives you versus what you owe it in dependencies, conventions, and ecosystem compatibility. This article compares them on routing power, handler ergonomics, middleware, and measured performance
