README

Simply create a .json file with the schema for your database, and run the artisan command json:migrate schema.json to create all the migrations for your project.

Note: This package is built to be used to kickstart your Laravel projects, and not to use on something that's already been built.

Installation

You can install this package by running the below composer command:

composer require --dev andyabih/json-to-laravel-migrations

Creating the JSON schema

Create a schema.json file in the root of your project, and use a template like the below:

{
    "posts": {
        "name"   : "string:50|index:50",
        "state"  : "enum:active,inactive|default:active",
        "text"   : "text",
        "slug"   : "string:50|unique",
        "active" : "boolean|default:false",
        "user_id": "foreign|nullable|constrained|onDelete"
    },

    "categories": {
        "name" : "string",
        "image": "string"
    },

    "subcategories": {
        "name"       : "string",
        "category_id": "foreign|constrained"
    }
}

The main keys of your JSON represent the table names. Make sure to create them in order in case a table has a relationship with another. In this case, posts, categories, and subcategories are our tables.

Next, for each table, define your columns as keys (so name, state, text, ... in this case), and set their properties.

Properties

Properties are separated with a pipe (|), and the first property should always be the column type. The package supports every column type in Laravel.

Additional options (such as string length) can be supplied using a colon (:), followed by the value of the option. Multiple options can be supplied (for float, for example).

Migrations

Run the above using:

php artisan json:migrate schema.json

The above schema will create something three different migrations. The posts schema will look like:

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreatePostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string("name", 50)->index();
            $table->enum("state", ['active', 'inactive'])->default('active');
            $table->text("text");
            $table->string("slug", 50)->unique();
            $table->boolean("active")->default(false);
            $table->foreignId("user_id")->nullable(true)->constrained()->onDelete('cascade');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Future plans

• Creating pivot tables.
• Creating models (with relationship).
• Backpack integration. Backpack is my favorite Admin panel, and would love to have something that integrates with them and creates CRUD controllers with fields automatically.
• Open to any suggestions! Whatever idea you have, please let me know.
