mongoose-find-by-whatever

0.0.2 • Public • Published

Model.findByWhatever('whatever')

Creates a find query based on the value you are trying to find by. I mostly use use this to add "login with username or password" option. For example User.findByWhatever(username or email) would turn into User.find({username: username}) or User.find({email: email}) based on some rules you define.

Install

npm install mongoose-find-by-whatever

How to use

Use like any other mongoose plugin and pass an array of rules as the 2nd argument. The order of the rules determines their precedence. A rule can be one of the following:

  • RegExp to test against value
  • Function that will get passed the value
  • "ObjectId" will search by _id
  • "*" will match anything
var whatevers = [{propertyName: rule}, {propertyName: rule}, ...];
UserSchema.plugin(require('mongoose-find-by-whatever'), [propertyName: rule]);

Example

// Given a User model
var UserSchema = mongoose.Schema({ name: String , email: String });
 
// define some finder rules
var whatevers = [
  {email: /@/} // Regexp
, {_id: 'ObjectId'} // ObjectId
, {secret: function (value) { return value.indexOf('secret') !== -1; }}
, {name:'*'} // Everything
];
 
UserSchema.plugin(require('mongoose-find-by-whatever'), whatevers);
User = mongoose.model('User', UserSchema);
 
User.findByWatever('bob@email.com') // Turns into User.find({email: 'bob@email.com'})
User.findByWatever('52aa38f7bcd27e0200000024') // Turns into User.find({_id: '52aa38f7bcd27e0200000024'})
User.findByWatever('bob') // Turns into User.find({name: 'bob'})
