Generate Image Placeholder
A cli tool which generates a json with base64 placeholders for a given set of images.
The tool resizes each image to a given size and transforms it into a base64 string which later on can be used as value for the src attribute of an img element until the full image is being loaded.
Installation
npm install -g gen-img-placeholder
Usage
gen-img-placeholder [options] <images glob pattern>
Options:
- -h, --help - output usage information
- -V, --version - output the version number
- -s, --size - New size for the placeholder, in percentage (default: 1%)
- -o, --output - Path for the output json (default: stdout)
Example
gen-img-placeholder -s 1 -o './placeholders.json' 'assets/**/*.png'
