Header files for Mongoose' 'plugin' method (extending via .methods and .statics)

Declare interfaces in passport-local-mongoose.d.ts file:

declare module 'mongoose' {    // methods    export interface PassportLocalDocument extends Document {        setPassword(pass: string, cb: (err: any) => void);    }    // statics    export interface PassportLocalModel<T extends PassportLocalDocument> extends Model<T> {        authenticate(username: string, password: string, cb: (err: any) => void);    }    // plugin options    export interface PassportLocalOptions {        usernameField?: string;        usernameLowerCase?: boolean;    }    export interface PassportLocalSchema extends Schema {        plugin(            plugin: (schema: PassportLocalSchema, options?: PassportLocalOptions) => void,            options?: PassportLocalOptions): Schema;    }    export function model<T extends PassportLocalDocument>(        name: string,        schema?: PassportLocalSchema,        collection?: string,        skipInit?: boolean): PassportLocalModel<T>;}declare module 'passport-local-mongoose' {    import mongoose = require('mongoose');    var _: (schema: mongoose.Schema, Options?: Object) => void;    export = _;}

Use it in your app.ts:

import mongoose = require('mongoose');import passportLocalMongoose = require('passport-local-mongoose');interface UserDocument extends mongoose.PassportLocalDocument {    email: string,    password: string;}var userSchema = <mongoose.PassportLocalSchema>new mongoose.Schema({    email: String,    password: String});userSchema.plugin(passportLocalMongoose, {    usernameField: 'email',    usernameLowerCase: true});var User = mongoose.model<UserDocument>('User', userSchema);User.authenticate(userName, pass, cb);var user = new User();user.setPassword(newPass, cb);
