Usage

Initialize Mongo Provider

First, you need to initialize the MongoProvider with your MongoDB configurations.

import { MongoProvider } from '@wistle/mongo';

// MongoDB configuration
const mongoDBConfig = {
  user: {
    url: 'mongodb://localhost:27017',
    dbName: 'wistleDB'
  }
};

// Initialize MongoProvider with multiple connections
await MongoProvider.addConnections(mongoDBConfig);

Using Mongo Service

Once the MongoProvider is initialized, you can use MongoService to perform MongoDB operations on a specific collection.

const mongoService = MongoProvider.getConnection('user');

// Example: Insert multiple users into the 'users' collection
const users = [
  { name: 'Alice', email: '[email protected]' },
  { name: 'Bob', email: '[email protected]' }
];
await mongoService.insertMany('users', users);

CRUD Operations

Insert Documents

const newUser = { name: 'Charlie', email: '[email protected]' };
await mongoService.insertOne('users', newUser);

Find All Documents

const allUsers = await mongoService.find('users');
console.log(allUsers);

Find by ID

const userId = 'someObjectIdHere';
const user = await mongoService.findById('users', userId);
console.log(user);

Update Document by ID

const userId = 'someObjectIdHere';
await mongoService.updateById('users', userId, { $set: { email: '[email protected]' } });

Delete Document by ID

const userId = 'someObjectIdHere';
await mongoService.deleteById('users', userId);

Aggregation

const aggregationPipeline = [
  { $match: { email: { $regex: /example.com$/ } } },
  { $group: { _id: null, total: { $sum: 1 } } }
];

const result = await mongoService.aggregate('users', aggregationPipeline);
console.log(result);

Pagination

const page = 1;
const limit = 10;
const users = await mongoService.paginate('users', {}, page, limit);
console.log(users);
