# trying-nestjs-ddd

Based on layered architecture.

# Development

- Install dependencies by running `yarn install`.

- Copy the **.env.example** as **.env**.

- Add values to the **.env**.

- Create **trying_nestjs_ddd** to your mysql database.

  - Initialize tables by running `yarn migration`.

  - Initialize data by running `yarn seed`.

  - If you wan't to use **in-memory repository**, switch the **REPOSITORY_TYPE** to **in-memory**.  

  In this case, no database is needed.

- Start development by running `yarn start:dev`.

# Rough requirement definition

- It's a task management application.

- It's a web server.

- The user is only you.

- Task contains rules below.

  - Task has it's name and done state.

  - Task name must not be duplicated.

  - Name of the task is 1 to 20 characters.

- It provides the following features.

  - Create a task.

  - Get all tasks.

  - Update a task.

  - Delete a task.

# Rough development policy

- Based on layered architecture.

- Since the unit of aggregation is only task, there are no modules or packages that are conscious of aggregation.

  - For example, there is no directory named task.

- Try not to depend on libraries as much as possible at the application or domain layers.

- Task identifiers are serial numbers.

- Executing domain behavior is not allowed in presentation layer.
