Node.JS MongoDB Order of Operations Use Case
What is the order of operations for the mongodb-native driver?
Let's say you have a class that's purpose is to save a document of some sort and let's say it has a long life. How many times should open be called? Once per db write? When is close supposed to be called? Essentially I want a class method that looks like this:
var myMongoClass = new MongoDB(server,port) myMongoClass.write_file(filename,callback) myMongoClass.write_doc(doc,callback)
I posted this a while ago and got it working: Problem with MongoDB GridFS Saving Files with Node.JS
It's now not working at all and failing with
TypeError: Cannot read property 'md5' of null
Every time I work with this library I want to bang my head through a wall.
It seems like the correct answer is create a client and keep that client open for the duration of the application (never explicitly calling close). I have a wrapper that keeps a reference to the connected client and my app only boots up if the connection is received.
