{"id":12624,"library":"vue2-dropzone","title":"Vue 2 Dropzone Component","description":"Vue2-dropzone is a Vue 2 wrapper component for the popular Dropzone.js library, enabling easy integration of drag-and-drop file upload functionalities into Vue applications. The current stable version is 3.6.0. While the project is functional and receives periodic maintenance updates for bug fixes, dependency upgrades (such as Dropzone.js itself), and minor feature enhancements like support for new image formats, it is actively seeking co-maintainers, indicating a shift towards community-driven maintenance. Its primary differentiator is providing a pre-packaged Vue 2 component for Dropzone.js, abstracting away direct DOM manipulation. A separate, Nuxt SSR-compatible version is also available from a different maintainer. Releases are typically driven by bug reports, security patches, and updates to the underlying Dropzone.js library.","status":"maintenance","version":"3.6.0","language":"javascript","source_language":"en","source_url":"ssh://git@github.com/rowanwins/vue-dropzone","tags":["javascript"],"install":[{"cmd":"npm install vue2-dropzone","lang":"bash","label":"npm"},{"cmd":"yarn add vue2-dropzone","lang":"bash","label":"yarn"},{"cmd":"pnpm add vue2-dropzone","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Provides the core drag-and-drop file upload functionality.","package":"dropzone","optional":false}],"imports":[{"note":"This component is typically imported as a default export and registered globally or locally within a Vue component.
