Development

Routes and Controllers

Set up routes at app/modules/routes/routes.ts importing the correct functions to the application. You should use Controllers at app/modules/controller to create database communication methods, and set up viewers at app/modules/routes/route-domain to instantiate and call controller's methods.

AbstractEntity

The AbstractEntity::class should be extended to every controller that will use database connection as it contains basic implementes methods that can be overridden.

import { AbstractEntity } from '@/abstract/AbstractEntity';
import { MyDataModel } from '@/interfaces/MyDataModel';

class MyController extends AbstractEntity {
 protected table = "MyTable";
 protected data: MyDataModel;
 
 constructor(data?: MyDataModel) {
     super();
     this.data = data;
 }

 async getCertainDocument(){
     const dbm = this.mongodb.connect();
     const collection = dbm.collection(this.table);
     const result = await collection.findAll();
     this.disconnect();
     return result;
 }

 async overrideFindOne(query: FilterQuery<any>, opts?: FindOneOptions<any>) {
     return await this.findOne(query, opts);
 }
 // ... other methods
}

CryptoJsHandler

CryptoJsHandler::class provides encryption and decryption methods. To start using, create a ssh key called crypto-js in app/.shh.

import { CryptoJsHandler } from '@/util/CryptoJSHandler';
 
 // Instantiates the handler
 const handler = new CryproJSHandler();
 
 // Encrypt some string
 const encrypted = handler.encrypt('MySensitiveData123');
 // encrypted = "e69b2774de366007b336f5cb0ea8ecb4336cbd69a4a5e6d4c7068fd59866a384"

 // Decript some string
 const decrypted = handler.decrypt(encrypted);
 // decrypted = "MySensitiveData123"
 

Documentation

Keep the documentation up to date before pushing up.

Services

Services are classes used to perform outside world communication such as any API, or external integration. The orientation of use will vary between Controllers and viewers, depending on what kind of job it will do. For example, if you need to proxy a request, use inside a viewer. If you need to check something while processing data, use inside a controller method.

Avoid using static methods and keep the single responsibility standard up to date. Use interfaces to better organize entities and control the data flow.

Deploy

Deploy this application using docker-compose up -d. This application uses a MongoDB container to support the platform.

You can use docker's mongodb container name as mongodb.host in environment file.

Before deploying, change docker-compose.yml with a secure username and password to mongodb and add it to the .env file.

Verify docker-compose's ports to avoid conflicts.
