What is validate.js?

validate.js is a 2kb vanilla JavaScript library for validating data against schemas, supporting primitives like strings and numbers, plus objects, arrays, unions, intersections, and custom rules. Drop the single file into any JS or TypeScript project—no bundler or npm needed—and use parse() to validate inputs with type narrowing, or is() for boolean checks. It follows Standard Schema for swapping with other libraries and handles validate json against schema tasks effortlessly.

Why is it gaining traction?

In a field packed with Zod and Valibot, it shines as pure vanilla JS: no dependencies, instant vendoring, and JSDoc-powered TypeScript types even in plain JS files. Developers love its hq vanilla tiny rocks simplicity amid github tiny trends like tiny c compiler or github tiny 11 builder—perfect for mini vanilla setups without build step bloat. The hook? It just works everywhere, from static sites to prototypes.

Who should use this?

Frontend devs building no-bundler sites, like htmx apps or vanilla TS dashboards, who need quick form or API validation. Suited for indie hackers prototyping with mini vanilla ice cream simplicity, or anyone validating user inputs without package.json overhead. Skip if you're in heavy npm ecosystems.

Verdict

Solid docs, full test coverage, and Standard Schema compliance make it usable now, but 12 stars and 1.0% credibility score signal early immaturity—expect tweaks ahead. Try for tiny vanilla extract projects; otherwise, stick to battle-tested alternatives.
