MongoDB

FoalTS provides two ways to interact with a MongoDB database in your application: Mongoose and TypeORM.

Usage with Mongoose​

Generating a new project with Mongoose​

When creating an application with the --mongodb flag, the CLI generates a new project with mongoose and @foal/mongoose installed. The User model is defined using this ODM as well as the create-user script.

foal createapp my-app --mongodb

Generating a model​

You cannot create entities in a Mongoose project, as it is specific to TypeORM. Instead, you can use this command to generate a new model:

foal g model <name>

Configuration​

The URI of the MongoDB database can be passed through:

  • the config file config/default.json with the mongodb.uri key,
  • or with the environment variable MONGODB_URI.

Example (config/default.json):

{
  ...
  "mongodb": {
    "uri": "mongodb://localhost:27017/db"
  }
}

Authentication​

The MongoDBStore​

npm install @foal/mongodb

If you use sessions with @TokenRequired or @TokenOptional, you must use the MongoDBStore from @foal/mongodb.

The fetchUser function​

Example with JSON Web Tokens:

import { JWTRequired } from '@foal/jwt';
import { fetchUser } from '@foal/mongoose';

import { User } from '../models';

@JWTRequired({ user: fetchUser(User) })
class MyController {}

Usage with TypeORM​

npm uninstall sqlite3
npm install mongodb

Configuration​

ormconfig.js

const { Config } = require('@foal/core');

module.exports = {
  type: "mongodb",
  database: Config.get2('database.database', 'string'),
  dropSchema: Config.get2('database.dropSchema', 'boolean', false),
  entities: ["build/app/**/*.entity.js"],
  host: Config.get2('database.host', 'string'),
  port: Config.get2('database.port', 'number'),
  synchronize: Config.get2('database.synchronize', 'boolean', false)
}

config/default.json

{
  "database": {
    "database": "mydb",
    "host": "localhost",
    "port": 27017
  }
}

Authentication​

The MongoDBStore​

npm install @foal/mongodb

If you use sessions with @TokenRequired or @TokenOptional, you must use the MongoDBStore from @foal/mongodb. The TypeORMStore does not work with noSQL databases.

The fetchMongoDBUser function​

user.entity.ts

import { Entity, ObjectID, ObjectIdColumn } from 'typeorm';

@Entity()
export class User {

  @ObjectIdColumn()
  id: ObjectID;

}

Example with JSON Web Tokens:

import { JWTRequired } from '@foal/jwt';
import { fetchMongoDBUser } from '@foal/typeorm';

import { User } from '../entities';

@JWTRequired({ user: fetchMongoDBUser(User) })
class MyController {}

Limitations​

When using MongoDB, there are some features that are not available:

  • the foal g rest-api <name> command,
  • and the Groups & Permissions system.
