Herbarium

Herbarium is a centralized and standardized repository and discovery service for Herbs objects (entities, use cases, repositories) allowing glues (ex: Herbs Shelf, herbs2rest, herbs2gql, herbs2knex, etc) to access, explore and find these objects.

Installing

$ npm install @herbsjs/herbarium

Initializing

const { herbarium } = require('@herbs/herbarium')
herbarium.requireAll(options)

This will require all entities, use cases and repositories files.

You can check which files were found within the herbarium.requireAll(options) method using:

const { herbarium } = require('@herbs/herbarium')
const retqAll = herbarium.requireAll(options)

/* Will return an object of array of files founded
 {
   entities:[],
   usecases":[],
   repositories:[]
  }
*/

Advanced Options

options:

• initialPath: (optional) default process.cwd()
• avoidFiles: (optional) default (fileName) => (fileName.includes('.spec.js') || fileName.includes('.test.js') ? false : fileName)
• onlySpecs: (optional) default (fileName) => (fileName.includes('.spec.js') ? fileName : false)
• entitiesPath: (optional) default /src/domain/entities
• usecasesPath: (optional) default /src/domain/usecases
• specPath: (optional) default /src/domain/
• repositoriesPath: (optional) default /src/infra/repositories

Adding Objects and Metadata

Entities

// src/domain/entities/item.js
const { entity, field } = require('@herbsjs/herbs')
const { herbarium } = require('@herbsjs/herbarium')

const Item =
    entity('Item', {
        ...
    })

module.exports =
    herbarium.entities
        .add(Item, 'Item')
        .entity

The second parameter of the herbarium.entities.add function is the entity id for herbarium. It is optional and if none is provided, it uses the entity name (Item).

Use Cases

// src/domain/usecases/item/createItem.js
const { usecase } = require('@herbsjs/herbs')
const { herbarium } = require('@herbsjs/herbarium')
const { Item } = require('../entities/item')

const createItem = (injection) =>
    usecase('Create Item', {
        ...
    })

module.exports =
    herbarium.usecases
        .add(createItem, 'CreateItem')
        .metadata({ group: 'Items', operation: herbarium.crud.create, entity: Item })
        .usecase

The second parameter of the herbarium.usecases.add function is the usecase id for herbarium. It is optional and if none is provided, it uses the usecase description (Create Item).

Specs

// src/domain/usecases/createItem.spec.js
const { spec, scenario, given, check } = require('@herbsjs/aloe')

const createItemSpec = spec({ 
    ...
    })

module.exports =
    herbarium.specs
        .add(createItemSpec, 'CreateItemSpec')
        .spec

The second parameter of the herbarium.specs.add function is the entity id for herbarium.

Repository

const { herbarium } = require('@herbsjs/herbarium')
const { Repository } = require("@herbsjs/herbs2knex")
const { Item } = require('../../../domain/entities/item')

class ItemRepository extends Repository {
    constructor(injection) {
        ...
    }
}

module.exports =
    herbarium.repositories
        .add(ItemRepository, 'ItemRepository')
        .metadata({ entity: Item })
        .repository

The second parameter of the herbarium.repositories.add function is the repository id for herbarium. It is optional and if none is provided, it uses the repository class name (ItemRepository).

Consuming Objects

all

const entities = herbarium.entities.all
const usecases = herbarium.usecases.all
const repositories = herbarium.repositories.all

findBy

const usecases = herbarium.usecases.findBy({
  operation: [
    herbarium.crud.create,
    herbarium.crud.update,
    herbarium.crud.delete,
  ],
})

get by id

const entity = herbarium.entities.get(1)
const usecase = herbarium.usecases.get("a")
const repository = herbarium.repositories.get(item)

TODO

• Improve Test Coverage (metadata, specialized objects, etc)
• Default IDs - No need to inform IDs when adding a item. Use entity name or use case description.
