MongoDB from a websocket, with extra features:
- Access-rights on documents
- Notifications
It works by sending {fn: someFunction, args: someArguments} following the syntax of Mongo's Java driver
Example in javascript:
send({fn:'find', args:[{a: 2}]}, function(d){console.log(d)})
send({fn:'save', args:[{a:3}]}, function(d){console.log(d)})
send({fn:'find', args:[{a: {$gt:2}}]}, function(d){console.log(d)})
send({fn:'findAndModify', args:[{a:3},{$set:{a:5,b:12}}]}, function(d){console.log(d)})
send({fn:'findAndModify', args:[{a:6},{a:5,b:12},true, false]}, function(d){console.log(d)})
send({fn:'remove', args:[{a: {$exists: true}}]}, function(d){console.log(d)})
//when you're authentified, access-rights are enabled
send({fn:'save', args:[{a:4, _canRemove:['john@gmail.com']}]}, function(d){console.log(d)})
send({fn:'save', args:[{a:5,_canRead:['john@gmail.com'],_canUpsert:['john@gmail.com'],_canRemove:['john@gmail.com']}]}, function(d){console.log(d)})
//notifications:
connected clients receive the update when their rights allow it
note: not all methods will trigger notifications findAndModify, findAndRemove do
update, remove won't since it just return the number of updates.
