Simple File System Storage Provider for mongoose-attachments.
$ npm install mongoose-attachments-localfs
The library will register automatically with mongoose-attachments by performing require and
return a reference to the mongoose-attachments plugin:
var attachments = require('mongoose-attachments-localfs');
For further instructions check mongoose-attachments.
localfs
The following snippet extends PhotoSchema to use mongoose-attachments and locate all the uploads in public directory, perfectly suited for Express.js applications:
var path = require('path');
var os = require('os');
var attachments = require('mongoose-attachments-localfs');
MySchema.plugin(attachments, {
directory: os.tmpdir(),
storage : {
providerName: 'localfs',
options: {
directory: '/absolute/path/to/public/images'
}
},
properties: {
image: {
styles: {
original: {
// keep the original file
},
thumb: {
thumbnail: '100x100^',
gravity: 'center',
extent: '100x100',
'$format': 'jpg'
},
detail: {
resize: '400x400>',
'$format': 'jpg'
}
}
}
}
});
MySchema.virtual('detail_img').get(function() {
return path.join('detail', path.basename(this.image.detail.path));
});
MySchema.virtual('thumb_img').get(function() {
return path.join('thumb', path.basename(this.image.thumb.path));
});
The URL to the images would then be http://<your host>/<mount path>/images prepended to the value of MyModel.detail_img and MyModel.thumb_img.
For other configurations check mongoose-attachments.
If you define a style called thumb and directory points to <web-app-dir>/public/images
When storing data into the schema, the thumbnail created by mongoose-attachemnts is stored as <web-app-dir>/public/images/thumb/<ObjectID>-thumb.<format>.
The absolute path to the image is stored in Model.image.<type>.path.
