fs-thumbnail

Node.js library that generates thumbnails for files in the file system.

Overview

fs-thumbnail was designed for Ogma. It generates thumbnails based on file system paths of files. It tries several different libraries and uses the best match to generate the thumbnail. Libraries used for thumbnail generation are listed below. The ones labelled with peer dependency must be installed separately, either using npm or your OS-specific package manager.

  • sharp (peer dependency: npm). Used for JPEG, PNG, WebP, TIFF, GIF and SVG images.
  • ffmpeg (peer dependency: OS-specific). Used to generate video thumbnails.

If you want to request support for a specific file type, please create an issue.

Installing

Install the main package:

npm install fs-thumbnail

Install some subset of peer dependencies that is relevant to your project:

# On all machines 
npm install sharp@0
 
# Make `ffmpeg` command available in your PATH. 
# E.g. on Debian and Ubuntu you can run: 
apt install ffmpeg

Now you can use the library:

const ThumbnailGenerator = require('fs-thumbnail');
const thumbGen = new ThumbnailGenerator({
    verbose: true, // Whether to print out warning/errors
    size: [500, 300], // Default size, either a single number of an array of two numbers - [width, height].
    quality: 70, // Default quality, between 1 and 100
});
 
thumbGen.getThumbnail({
    path: '/path/to/my/image.png',
    output: '/thumbnail/folder/thumbnail.jpg',
    size: 300, // You can override the default size per thumbnail
    quality: 70, // You can override the default quality per thumbnail
})
    .then(thumbnailPath => {
        if (!thumbnailPath) console.log('Could not generate the thumbnail!');
        else console.log(`Thumbnail generated! Find it here: ${thumbnailPath}`);
    });

Install
