@ghatul , I was thinking about it, when I will have a free time I will implement integration with mongo :)

[Valentyn Yakymenko]

@ghatul , can you provide more details what are not working for you ?

[krishna ghatul]

i use https://github.com/mgechev/angular2-seed this seed project and build my client and server in nodejs with typescript with mongo , i try to integrate client and server as per your seed ,i suceesfully integrate client but i getting confused for integration of server ...

[Valentyn Yakymenko]

@ghatul , any errors? Have you read the documentation in README.md ?

[krishna ghatul]

yes , i read that

[Valentyn Yakymenko]

@ghatul , can you show your .ts or .js code to connect with MongoDB ?

[krishna ghatul]

`import Mongoose = require("mongoose");

class DataAccess {
static mongooseInstance:any;
static mongooseConnection:Mongoose.Connection;

constructor() {
    DataAccess.connect();
}

static connect():Mongoose.Connection {
    if (this.mongooseInstance) return this.mongooseInstance;

    this.mongooseConnection = Mongoose.connection;
    this.mongooseConnection.once("open", () => {
        console.log("Connected to mongodb.");
    });
    this.mongooseInstance = Mongoose.connect('mongodb://127.0.0.1/seed-backend');
    return this.mongooseInstance;
}

}
DataAccess.connect();
export = DataAccess;
`

@ghatul , have you installed typings install dt~mongoose --save --global ?
You MongoDB is running ? What error do you have? Maybe you have some debug log ?
Code in ts or js ?

Hi, i'm using mongoose in my project with this seed and it's working as expected...

[André Silva]

typings.json
"mongoose": "registry:dt/mongoose#4.5.4+20160807120805",

db.conf.ts

'use strict';

import * as mongoose from 'mongoose';

export class DBConfig {

  static init(): void {

    const URL = 'mongodb://xxxxx/database';
    mongoose.connect(URL, (err) => {

      if (err) {

        console.log(err.message);
        console.log(err);

      } else {

        console.log('Connected to MongoDb');
      }
    });
  }
}

then in server/index.ts we just need to init the DBConfig

import { DBConfig } from './configs/db.conf';

var _clientDir = '../client';
var app = express();

export function init(port: number, mode: string) {

  app.use(bodyParser.urlencoded({extended: false}));
  app.use(bodyParser.json());
  app.use(bodyParser.text());
  app.use(compression());

  // DB Init
  DBConfig.init();
...
}

and this is one example of mongoose model

import * as mongoose from 'mongoose';

export class ExportState {
  static Processing: string = 'Processing';
  static Finished: string = 'Finished';
  static Failed: string = 'Failed';
  static Deleted: string = 'Deleted';
}

export interface FiltersInterface {
  startDate: Date;
  endDate: Date;
  users: string[];
  dataTypes: string[];
  lowQualityValues: boolean;
}

export interface ExportResult {
  medableExportDuration: number; // in miliseconds
  internalExportDuration: number; // in miliseconds
  numberOfLines: number;
  fileSize: number; // in bytes
}

export interface ExportInterface {
  userId: string;
  name: string;
  filters: FiltersInterface;
  state: string;
  fileUrl: string;
  fileName: string;
  exportResultDetails: ExportResult;
  creationTime: Date;
  deletionTime: Date;
}

export const DataExportSchema = new mongoose.Schema({
  userId: String,
  name: String,
  filters: {
    startDate: Date,
    endDate: Date,
    users: [String],
    dataTypes: [String],
    lowQualityValues: Boolean
  },
  state: String,
  fileUrl: String,
  fileName: String,
  exportResultDetails: {
    medableExportDuration: Number,
    internalExportDuration: Number,
    numberOfLines: Number,
    fileSize: Number
  },
  creationTime: Date,
  deletionTime: Date
}, {versionKey: false});

export interface DataExportType extends ExportInterface, mongoose.Document {
}

export const DataExport = mongoose.model < DataExportType >('DataExport', DataExportSchema);

thanks !
typings install dt~mongoose --save --global work for me
