API
You can use this library with callbacks, or with promises.
callbacks
var thumb = require('node-thumbnail').thumb;
// thumb(options, callback);
thumb({
source: 'source/path', // could be a filename: dest/path/image.jpg
destination: 'dest/path',
concurrency: 4
}, function(files, err, stdout, stderr) {
console.log('All done!');
});default options:
defaults = {
prefix: '',
suffix: '_thumb',
digest: false,
hashingType: 'sha1', // 'sha1', 'md5', 'sha256', 'sha512'
width: 800,
concurrency: <num of cpus>,
quiet: false, // if set to 'true', console.log status messages will be supressed
overwrite: false,
skip: false, // Skip generation of existing thumbnails
basename: undefined, // basename of the thumbnail. If unset, the name of the source file is used as basename.
ignore: false, // Ignore unsupported files in "dest"
logger: function(message) {
console.log(message);
}
};Note you must specify at least source and destination
promises
The options that you can pass in are the same as above.

console.log('Success');
}).catch(function(e) {
console.log('Error', e.toString());
