Let’s get started.


What is Laravel Fake JSON REST APIs Server

This is a kind of laravel application which provides you the access of fake rest apis to test and prototype any application. This is entirely free to use.

Generally, this library application is designed to accept and create fake rest apis set by a json file i.e db.json. You need to take care of the steps to create db.json file and place correctly as this tutorial guide you. By using this application you will create fake rest apis for HTTP Methods – GET, POST, PUT, PATCH, DELETE.

You can see an example here OWT fakeAPIs.

Other than this concept several planning regarding to extend the functionality in in progress.


How to Install Setup

To setup this application, firstly this is built in laravel 8 framework so you need to install everything what laravel 8 requires. Laravel 8 Installation Guide – PHP Framework

Clone github repository

You need to clone this github repository to setup the entire application. Here is the command.

Open terminal or command prompt and run it.

$ git clone https://github.com/owthub/laravel-json-fake-apis-server-using-json-file.git

Output

Cloning into 'laravel-json-fake-apis-server-using-json-file'...

It will download a folder with name laravel-json-fake-apis-server-using-json-file inside your system.

Open project into terminal and run artisan command to start development server

$ php artisan serve

URL: http://127.0.0.1:8000/

Alternative way,

Open project in browser (Check your system path), In this case it is –

http://localhost/laravel-json-fake-apis-server-using-json-file

If you get error of /storage/logs/laravel.log then you need to give a proper permission to /storage folder.

You will get welcome page as-

These all routes scanned and automatically created using db.json file. This db.json file exists inside /storage/json folder. You can go and check it.

When you click on any route like /employees

You can use this system by different different HTTP Request Methods like GET, POST, PUT/PATCH, DELETE.

Now, if you are thinking how can we override this existing system with your own data. Trust me it’s very very simple now to do.

Let’s see how to setup new apis routes. To setup new apis routes you need to only replace with new db.json file.


Create db.json File

When you clone setup, you will find a file db.json inside /storage/json folder. If you want something different data other than this then you need a updated db.json file. Other wise you can also work with the existing db.json file.

How To Create

db.json file is a json file as it’s extension tells you.

Routes Setup

To create resource routes you need to create json properties. For example: Routes as –

  • URL/students
  • URL/posts
  • URL/comments

JSON format should be like this – (db.json)

{
	"students": [

	],
	"posts": [

	],
	"comments": [

	]
}

Properties Setup / Fields Setup

To make everything perfect for REST APIs, needs to add an “id” field or property with each object. Rest you can add more fields as per api needs. Other than this you can create multiple objects inside each array.

So db.json will be like this –

{
    "students": [
        {
            "id": 1,
            "name": "Sanjay Kumar",
            "email": "sanjay@gmail.com"
        },
        {
            "id": 2,
            "name": "Vijay Rohila",
            "email": "vijay@gmail.com"
        },
        {
            "id": 3,
            "name": "Dhananjay Negi",
            "email": "dhananjay@gmail.com"
        },
        {
            "id": 4,
            "name": "Ashish Kumar",
            "email": "ashish@gmail.com"
        },
        ...
    ],
    "posts": [
        {
            "id": 1,
            "title": "Sample Post 1",
            "description": "This is sample post 1"
        },
        {
            "id": 2,
            "title": "Sample Post 2",
            "description": "This is sample post 2"
        },
        ...
    ],
    "comments": [
        {
            "id": 1,
            "title": "Sample comment 1",
            "description": "This is sample comment 1"
        },
        {
            "id": 2,
            "title": "Sample comment 2",
            "description": "This is sample comment 2"
        },
        ...
    ]
}

Now, you are able to use routes as –

  • URL/students – List all data
  • URL/posts
  • URL/comments
  • URL/students/{studentId} OR URL/students?id={studentId} – List single data
  • URL/posts/{postId} OR URL/posts?id={postId}
  • URL/comments/{commentId} OR URL/comments?id={commentId}

Available HTTP Methods – GET, POST, PUT / PATCH, DELETE.

Relationship Setup

If you have some data like this –

  • A Student have many posts
  • A Post have many comments

Inside student “id” will be as a primary key identifier and inside post object “studentId” is the identifier to identify the posts. Similarly inside comments we will have “postId” inside comments object.

Syntax:

{singularResourceName}Id

Example:

studentId, postId

So you need to create db.json file like this –

{
  "students":[
    {
        "id": 1,
        "name": "Sanjay Kumar",
        "email": "sanjay@gmail.com"
    },
    ...
  ],
  "posts":[
    {
        "id": 1,
        "studentId": 1,
        "title": "Sample post 1",
        "description": "This is sample post 1"
    },
    {
        "id": 2,
        "studentId": 1,
        "title": "Sample post 2",
        "description": "This is sample post 2"
    },
    {
        "id": 3,
        "studentId": 2,
        "title": "Sample post 3",
        "description": "This is sample post 3"
    }
    ...
  ],
  "comments":[
    {
        "id": 1,
        "postId": 1,
        "title": "Sample comment 1",
        "description": "This is sample comment 1"
    },
    {
        "id": 2,
        "postId": 1,
        "title": "Sample comment 2",
        "description": "This is sample comment 2"
    },
    ...
  ]
}

Available routes for relational data

  • URL/students/{studentId}/posts – List all posts by student id
  • URL/students/posts?studentId={studentId}
  • URL/posts/{postId}/comments – List all comments by post id
  • URL/posts/comments?postId={postId}

Final Words

Inside this laravel fake json rest api server, you need to keep these things while creating db.json file. This db.json file is the main file for your fake apis as well as it is decider for ret apis endpoints.

  • Routes should be created in plural and they should be the name of property inside object like
{ "students": [], "posts": [], … }
  • First value of any object should be an “id” field. Rest you can define any number of keys as per apis need.
{ "students": [ { "id": 1, "name": "Sample" }, { "id": 2, "name": "Sample" } ], … }
  • Relationship between resources as “id” for their tables and {singular}Id as for others to connect. Like “id” inside students, but for posts it will be “studentId” which connects two resources students and posts.
  • db.json file should placed inside /storage/json folder.
  • Resources names should be plural.
  • When you execute POST, PUT/PATCH, DELETE request with fake apis, they will execute even they will return a perfect json output but they don’t do anything at server. Means they don’t save, update or delete anything in real.
