Answer 1

The Schema object you're passing may not work correctly because you are nesting 'unique' attribute into 'index' attribute, try something like this (it works as intended) :

User = mongoose.model('User', new Schema({
    firstName:  {
        type:String,
        required: true,
    },
    lastName: {
        type:String,
        required: true,
    },
    email: {
        type:String,
        required: true,
        unique: true
    },
    address: String,
    phone: {
        type:String,
        required: true,
    },
    password:  {
        type:String,
        required: true,
        set: Data.prototype.saltySha1 // some function called before saving the data
    },
    role: String
},{strict: true}));

Or more specifically for your example :

var Tasks = new Schema({
    project: { 
        type: String, 
        unique: true,
        index: true
    },
    description: String
});

Note : I don't know what you're trying to do with the "dropDups" parameter, it doesn't seems to be in the mongoose documentation.
