papercut.set('storage', 'file')
papercut.set('directory', './images/uploads')
papercut.set('url', '/images/uploads')
});
papercut.configure('production', function(){
papercut.set('storage', 's3')
papercut.set('S3_KEY', process.env.S3_KEY)
papercut.set('S3_SECRET', process.env.S3_SECRET)
papercut.set('bucket', 'papercut')
});
AvatarUploader = papercut.Schema(function(schema){
schema.version({
name: 'avatar',
size: '200x200',
process: 'crop'
});
schema.version({
name: 'small',
size: '50x50',
process: 'crop'
});
});
uploader = new AvatarUploader();
uploader.process('image1', file.path, function(images){
console.log(images.avatar); // '/images/uploads/image1-avatar.jpg'
console.log(images.small); // '/images/uploads/image1-small.jpg'
})
In papercut, you can set the image directory and default process by getter and setter:
var papercut = require('papercut');
//storage type, have file and s3
papercut.set('storage', 'file');
//directory for saving image
papercut.set('directory', './images/uploads');
//url path to the directory
papercut.set('url', '/images/uploads');
//set output images extension
papercut.set('extension', 'jpg');
Also, you can set the environment dependent configuration, it detect the process.env.NODE_ENV
param.
you can call export NODE_ENV=[environment]
to change environment.
papercut.configure('production', function(){
//set storage to s3 for production environment
papercut.set('storage', 's3');
//set s3 key from environment.
papercut.set('S3_KEY', process.env.S3_KEY);
papercut.set('S3_SECRET', process.env.S3_SECRET);
//s3 bucket name
papercut.set('bucket', 'papercut');
});
After configuration, you can create an uploader to process images with multiple version by Schema
var Uploader = papercut.Schema(function(schema){
schema.version({
name: 'thumbnail',
size: '45x45',
process: 'crop'
});
schema.version({
name: 'large',
size: '600x480',
process: 'resize'
});
schema.version({
name: 'origin',
process: 'copy'
});
});
With uploader, you can pass the image identifier and image path to process images.
Also with images url in different versions:
var uploader = new Uploader();
uploader.process('412341', '/tmp/13912304.jpg', function(err, images){
console.log(images);
// {
// thumbnail: '/images/upload/412341-thumbnail.jpg',
// large: '/images/upload/412341-large.jpg',
// origin: '/images/upload/412341-origin.jpg'
// }
});
