Installation

Getting Started

You are looking at the depricated version of the docs. See https://docs.lucidarch.dev for the latest documentation.

This is no longer the way to install Lucid, see installation docs for the modern method.

Laravel • Lucid Monolith

This example uses Laravel with the Lucid Monolith installation (in contrast with Microservice). For more on the differences see Definitions [coming soon].

Initialise a Laravel project with Lucid, using the latest version:

composer create-project lucid-arch/laravel lucid-demo

This will install a new Laravel project with the latest version, structured as per the Lucid architecture, as well as the Lucid Console which provides a command line interface and a user interface to help you manage your Lucid components.

To install a specific version use notation such as lucid-arch/laravel=5.8.x instead of lucid-arch/laravel. This is literally 5.8.x and not 5.8.0 or 5.8.1.

Directory Structure

What you should know about the directories that you will find in addition to the ones included in Laravel by default:

src
├── Data
├── Domains
    └── * domain name *
            ├── Jobs
├── Foundation
└── Services
    └── * service name *
        ├── Console
        ├── Features
        ├── Http
        ├── Providers
        ├── Tests
        ├── database
        └── resources

Components

Use the table below to help you place the different Lucid components

Component Definitions

Component	Path	Description
Service	src/Service/[service]	Place for the Services
Feature	src/Services/[service]/Features/[feature]	Place for the Features of Services
Job	src/Domains/[domain]/Jobs/[job]	Place for the Jobs that expose the functionalities of Domains
Operation	src/Operations	Place for the Operation that can call multiple Jobs from different domains
Data	src/Data	Place for models, repositories, value objects and anything data-related
Foundation	src/Foundation	Place for foundational (abstract) elements used across the application

Setup

The lucid executable will be in vendor/bin. If you don't have ./vendor/bin/ as part of your shell PATH you will need to execute it using ./vendor/bin/lucid, otherwise add it with the following command to be able to simply call lucid when in the project's root directory [recommended]:

export PATH="./vendor/bin:$PATH"

For a list of all the commands that are available run lucid or see the CLI Reference.

Seek your shell session's docs to see how to add this to your shell profile permanently.

Description

Before we dive into code, here's what we are about to do:

We will create an application with basic functionality to create and list articles, where an article simply having title and content. The application will have two services: Api and Admin . Each will expose the features correspondingly, where the Api service will receive and return JSON data, while Admin will serve them rendered using Blade.

Overview

• Part I

  1. Create Api Service

  2. Write functionality & tests

  3. Serve feature

• Part II

  1. Create Admin Service

  2. Share functionality from Api

  3. Add display functionality

  4. Test Admin [manual]

• Part III

  • Repository pattern for data storage

  • Optional Job parameters

  • Operations

  • Error handling

    • Abstraction in sharing data provider between validation and feature?
