About Código ao Ponto

Código ao Ponto is a hub of free browser-based developer tools alongside articles and videos covering web development topics such as Vue.js, Node.js, and React.js. The tools include generators and validators for Brazilian identification formats (CPF, RG, CNPJ) and credit card numbers for testing purposes, a UUID generator supporting v4 and v7 in bulk, and a JSON formatter with validation and a tree view. Tools require no sign-up and run directly in the browser.

The content side publishes weekly articles and videos aimed at teaching programming in a practical, concise format, with topics spanning frameworks like Vue and Nuxt, JavaScript fundamentals, and career advice. The site is run by Thiago Nunes Batista, a senior front-end developer with experience in React, Nuxt, and Vue, who also speaks at technology events on topics like web performance and native browser APIs.

The site is aimed at developers looking for quick-access testing utilities and at those learning or improving their skills in front-end and JavaScript-adjacent technologies through articles and video lessons.
