How to store large numbers in MongoDB with Node.js

Question

I am using MongoDB with the native node driver and need to accurately store numbers that may be larger than the int maximum 2147483647. I will need to be able to increment t

Answer 1

MongoDB has a native 64-bit long integer type, usually called NumberLong (at least in the MongoDB javascript shell/driver). If you're using the node-mongodb-native driver, I believe it is just called Long (though I am not certain of this, someone please correct me if I'm wrong). $inc works as expected against fields of type NumberLong.

Answer 2

You can now do this in Mongoose with the mongoose-long plug-in.

require('mongoose-long')(mongoose);
var SchemaTypes = mongoose.Schema.Types;
var schema = new Schema({
    ...
    usedBandwidth: {type: SchemaTypes.Long, min: 0, default: 0}
});
