Alterior MongoDB Support

NOTE: This library is intended for use with Alterior 2.x. It is not compatible with Alterior 3.x.

Use this package if you want to connect to MongoDB from your Alterior application.

Accessing MongoDB from Alterior

npm i mongodb @alterior/mongo

Now use mongoProvider to inject an instance of mongodb.Db into your application:

import { AppOptions } from '@alterior/core';
import { mongoProvider } from '@alterior/mongo';
import * as mongodb from 'mongodb';

@AppOptions({
    providers: [mongoProvider(mongodb.Db)]
})
class App { 
}

Now, you can inject mongodb.Db into your controllers:

import { Controller, Get } from '@alterior/core';
import * as mongodb from 'mongodb';

@Controller()
class SampleController {
    constructor(
        private db : mongodb.Db
    ) {
    }
    
    @Get('/stuff')
    public getStuff() {
        return this.db.collection('stuff').find().toArray();
    }
}

You can pass any token into mongoProvider, which can be used to inject multiple database connections if necessary.

Storing Sessions in MongoDB

This package also provides a connector for storing Express sessions in MongoDB using mongo-connect.

import * as mongodb from 'mongodb';
import { mongoProvider, mongoSession } from '@alterior/mongo';

@AppOptions({
	providers: [mongoProvider(mongodb.Db)]
	middleware: [mongoSession(mongodb.Db, SESSION_SECRET)]
})
export class App { }

You can then access and modify session data from your route methods. We recommend you make an interface representing your session data.

interface SessionData {
	displayName : string;
	cartTotal : number;
}

@Controller()
class SampleController {
	@Get('/cart/total') 
	public get(session : SessionData) {
		return session.cartTotal;
	} 
}
