## Changelog
|
||||
|
||||
|
||||
- Inicializamos el proyecto, usando npm init, con la node@latest (v24.4.1)
|
||||
- Añadimos dependencias que voy a usar
|
||||
- Creo una estructura de directorio inicial
|
||||
- Añado un primer test (database.test.ts) para jest

||||

|
||||
|
||||
- [#1 PR : feat/project_structure ](https://github.com/aabril/dailytrends/pull/1)

- Añado un primer test (database.test.ts) para jest
|
||||
|
||||
- [#2 PR : feat/database_and_feed_model ](https://github.com/aabril/dailytrends/pull/2)
|
||||
- Añadimos `moongose` a las dependencias
|
||||
- Añado un docker-compose con mongo local (luego lo ampliaré para esta propia app)
|
||||
- Modificar el docker para tenerlo multistage y reducir el tamaño de las imagenes de contenedores
|
||||
- añadir documentación de Docker, docker-compose
|
||||
- añadir documentación de las capas de abstracción de "Feed"
|
||||
- añadir tests para la conexión con la base de datos con Mocks (el mocking aqui a veces se complica)
|
||||
- añadir primeras definiciones de Feed, empezaremos de lowerst a higher abstraction: tipo -> modelo -> repo -> servicio -> controller
|
||||
|
||||
|
||||
## Feed layer abstractions
|
||||
|
||||
From higher to lower:
|
||||
|
||||
- Layer 1: HTTP/Controller (Highest Abstraction)
|
||||
- `FeedController.ts` : Handles HTTP requests/responses, API endpoints
|
||||
|
||||
- Layer 2: Business Logic/Service
|
||||
- `FeedService.ts` : Implements business rules, validation, orchestration
|
||||
|
||||
- Layer 3: Data Access/Repository
|
||||
- `FeedRepository.ts` : Abstracts database operations, CRUD methods
|
||||
|
||||
- Layer 4: Data Model/Schema
|
||||
- `Feed.ts` : Mongoose schema, database validations, indexes
|
||||
|
||||
- Layer 5: Type Definitions (Lowest Abstraction)
|
||||
- `Feed.ts` : TypeScript interfaces, enums, DTOs
|
||||
- `config.ts` : Configuration settings
|
||||
|
||||
## Dockerfile simple to multistage
|
||||
|
||||
I rebuild the Dockerfile to be multistage, since the image was heavy because all the node_modules dependencies.
|
||||
The size of the image has been reduced from 717Mb to 376.
