Micromodal is a lightweight JavaScript library for creating accessible modal dialogs. The library addresses the challenge of building modals that meet accessibility standards without requiring heavy dependencies or complex configuration. It handles the core accessibility concerns automatically: toggling ARIA attributes on open and close, trapping tab focus within the modal, focusing the first focusable element, and restoring focus to the previously focused element after the modal closes. The tool also manages common user interactions like closing on overlay click or pressing the escape key, and supports nested modals.
Developers should choose this tool if they need a minimal, dependency-free solution for modal dialogs and want accessibility built in from the start rather than bolted on afterward. The library is particularly suited to projects where bundle size matters or where you want to avoid framework-specific modal solutions. At roughly 1.8kb minified and gzipped, it integrates easily into vanilla JavaScript projects or as a complement to existing frameworks.
The project maintains an open contribution process with a simple development setup: cloning the repository, installing dependencies, and running a dev server with live reload. The codebase follows the standardjs coding standard, enforced through the package configuration. The team actively manages releases through a structured process involving version updates, changelog maintenance, and automated documentation deployment to GitHub Pages triggered by release creation. The project is actively seeking additional core maintainers to share maintenance responsibilities.
