Exemplary real world backend API built with Lumen + MongoDB
Lumen + MongoDB codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API.
Demo RealWorld
This codebase was created to demonstrate a fully functional REST API built with Lumen + MongoDB, including CRUD operations, authentication, routing, pagination, and more.
It borrows heavily from the excellent Laravel implementation by SandeeshS.
For more information on how this works with other frontends/backends, head over to the RealWorld repo.
Hope you'll find this example helpful. Pull requests are welcome!
Getting started
Installation
Please check the official Lumen installation guide for server requirements before you start. Official Documentation
Clone the repository
git clone [email protected]:elcobvg/lumen-realworld-example-app.git
Switch to the repo folder
cd lumen-realworld-example-app
Install all the dependencies using composer
composer install
Copy the example env file and make the required configuration changes in the .env file
cp .env.example .env
Generate a new application key
Since Lumen doesn't have the php artisan key:generate command, there's a custom route http://localhost:8000/appKey to help you generate an application key.
Generate a new JWT authentication secret key
php artisan jwt:secret
Run the database migrations (Set the database connection in .env before migrating)
php artisan migrate
Start the local development server
php -S localhost:8000 -t public
You can now access the server at http://localhost:8000
TL;DR command list
git clone git@elcobvg/lumen-realworld-example-app.git
cd lumen-realworld-example-app
composer install
cp .env.example .env
php artisan key:generate
php artisan jwt:secret
Make sure you set the correct database connection information before running the migrations Environment variables
php artisan migrate
php -S localhost:8000 -t public
Database seeding
Populate the database with seed data with relationships which includes users, articles, comments, tags, favorites and follows. This can help you to quickly start testing the api or couple a frontend and start using it with ready content.
Run the database seeder and you're done
php artisan db:seed
Note : It's recommended to have a clean database before seeding. You can refresh your migrations at any point to clean the database by running the following command
php artisan migrate:refresh
API Specification
This application adheres to the api specifications set by the Thinkster team. This helps mix and match any backend with any other frontend without conflicts.
