Example
However, if you're really serious about storage, and you want to store millions of images, you're going to need to leverage Mongo's GridFS infrastructure, and create yourself a storage layer. For that, you're going to need the excellent CollectionFS subsystem.
Start by adding the necessary packages.
meteor add cfs:standard-packages
meteor add cfs:filesystem
And adding a file upload element to your object model.
<template name="yourTemplate">
<input class="your-upload-class" type="file">
</template>
Then add an event controller on the client.
Template.yourTemplate.events({
'change .your-upload-class': function(event, template) {
FS.Utility.eachFile(event, function(file) {
var yourFile = new FS.File(file);
yourFile.creatorId = Meteor.userId(); // add custom data
YourFileCollection.insert(yourFile, function (err, fileObj) {
if (!err) {
// do callback stuff
}
});
});
}
});
And define your collections on your server:
YourFileCollection = new FS.Collection("yourFileCollection", {
stores: [new FS.Store.FileSystem("yourFileCollection", {path: "~/meteor_uploads"})]
});
YourFileCollection.allow({
insert: function (userId, doc) {
return !!userId;
},
update: function (userId, doc) {
return doc.creatorId == userId
},
download: function (userId, doc) {
return doc.creatorId == userId
}
});
Thanks to Raz for this excellent example. You'll want to check out the complete CollectionFS Documentation for more details on what all CollectionFS can do.
