Advanced tools
Uppy plugin that generates small previews of images to show on your upload UI.
@uppy/thumbnail-generator is a plugin for the Uppy file uploader that generates image thumbnails for preview purposes. It is particularly useful for providing users with a visual representation of the images they are uploading.
Generate Thumbnails
This feature allows you to generate thumbnails for images that are being uploaded. The `thumbnailWidth` option specifies the width of the generated thumbnail. The `thumbnail:generated` event is triggered when a thumbnail is successfully created, providing the file and preview URL.
const Uppy = require('@uppy/core');
const ThumbnailGenerator = require('@uppy/thumbnail-generator');
const uppy = Uppy();
uppy.use(ThumbnailGenerator, {
thumbnailWidth: 200,
});
uppy.on('thumbnail:generated', (file, preview) => {
console.log(file.name, preview);
// You can now use the preview URL to display the thumbnail
});Custom Thumbnail Dimensions
This feature allows you to specify custom dimensions for the generated thumbnails. By setting both `thumbnailWidth` and `thumbnailHeight`, you can control the size of the thumbnails more precisely.
const Uppy = require('@uppy/core');
const ThumbnailGenerator = require('@uppy/thumbnail-generator');
const uppy = Uppy();
uppy.use(ThumbnailGenerator, {
thumbnailWidth: 300,
thumbnailHeight: 300,
});
uppy.on('thumbnail:generated', (file, preview) => {
console.log(file.name, preview);
// You can now use the preview URL to display the thumbnail
});Thumbnail Quality
This feature allows you to set the quality of the generated thumbnails. The `quality` option accepts a value between 0 and 1, where 1 is the highest quality.
const Uppy = require('@uppy/core');
const ThumbnailGenerator = require('@uppy/thumbnail-generator');
const uppy = Uppy();
uppy.use(ThumbnailGenerator, {
thumbnailWidth: 200,
quality: 0.8,
});
uppy.on('thumbnail:generated', (file, preview) => {
console.log(file.name, preview);
// You can now use the preview URL to display the thumbnail
});Sharp is a high-performance image processing library that can resize, crop, and convert images in various formats. Unlike @uppy/thumbnail-generator, which is specifically designed for generating thumbnails within the Uppy ecosystem, Sharp is a more general-purpose library that can be used in a variety of image processing tasks.
Jimp is an image processing library for Node.js that supports image resizing, cropping, and various other manipulations. Similar to Sharp, Jimp is a general-purpose library and not specifically tied to any file uploader like Uppy. It offers a wide range of image processing functionalities.
GraphicsMagick (gm) is a Node.js wrapper for the GraphicsMagick and ImageMagick image processing libraries. It provides extensive image manipulation capabilities, including resizing and thumbnail generation. Unlike @uppy/thumbnail-generator, gm is not specifically designed for integration with file uploaders but offers a broader range of image processing features.
Uppy plugin that generates small previews of images to show on your upload UI.
Uppy is being developed by the folks at Transloadit, a versatile file encoding service.
const Uppy = require('@uppy/core')
const ThumbnailGenerator = require('@uppy/thumbnail-generator')
const uppy = Uppy()
uppy.use(ThumbnailGenerator, {
thumbnailWidth: 200
})
$ npm install @uppy/thumbnail-generator --save
We recommend installing from npm and then using a module bundler such as Webpack, Browserify or Rollup.js.
Alternatively, you can also use this plugin in a pre-built bundle from Transloadit's CDN: Edgly. In that case Uppy will attach itself to the global window.Uppy object. See the main Uppy documentation for instructions.
