I've been trying for the last hour to write a user module for passport.js with the findOne, findOneOrCreate, etc. methods, but can't get it right.
User.js
var User = function(db) {
this.db = db;
}
User.prototype.findOne(email, password, fn) {
// some code here
}
module.exports = exports = User;
app.js
User = require('./lib/User')(db);
User.findOne(email, pw, callback);
I've been through dozens of errors, mostly
TypeError: object is not a function
or
TypeError: Object function () {
function User(db) {
console.log(db);
}
} has no method 'findOne'
How do I create a proper module with these functions without creating an object/instance of User?
Update
I went over the proposed solutions:
var db;
function User(db) {
this.db = db;
}
User.prototype.init = function(db) {
return new User(db);
}
User.prototype.findOne = function(profile, fn) {}
module.exports = User;
No luck.
TypeError: Object function User(db) {
this.db = db;
} has no method 'init'
A couple of things are going on here, I've corrected your source code and added comments to explain along the way:
lib/User.js
// much more concise declaration
function User(db) {
this.db = db;
}
// You need to assign a new function here
User.prototype.findOne = function (email, password, fn) {
// some code here
}
// no need to overwrite `exports` ... since you're replacing `module.exports` itself
module.exports = User;
app.js
// don't forget `var`
// also don't call the require as a function, it's the class "declaration" you use to create new instances
var User = require('./lib/User');
// create a new instance of the user "class"
var user = new User(db);
// call findOne as an instance method
user.findOne(email, pw, callback);
You need to new User(db) at some point.
You could make an init method
exports.init = function(db){
return new User(db)
}
And then from your code:
var User = require(...).init(db);
