JSONPath looks simple until you actually need a filter, a slice, or a recursive match - then the handful of symbols that looked obvious start behaving unpredictably. This is a complete reference: every operator with a…
I recently shipped Mermaid diagram support to Forem, the open source platform that powers DEV. Fenced mermaid code blocks now render as actual diagrams instead of plain highlighted source. Which means this renders,…
Axios has gained another 7 stars today, a small signal that this promise-based HTTP client remains relevant across browser applications, Node.js services, and internal platform tooling. Its appeal is straightforward: a…
