Response Generator

Json Response Generator for Laravel Projects

I use this package to make it easier to change the JSON response structure.

Introduction

Use this package to make more flexible responses. This package can only be used in Laravel.

Usage

First install the package via composer using the following command :

composer requires milito/response-generator

Then import the MilitoResponseGeneratorServiceProvider service provider to config/app.php file :

<?php

return [
    //....
    
    "providers" => [
        //...
                \Milito\ResponseGenerator\Providers\MilitoResponseGeneratorServiceProvider::class,
        //...
    ]
];

Now you can use MilitoResponseGenerator facade to generate your responses.

• MilitoResponseGenerator::success() : SuccessState This is used for success responses.
• MilitoResponseGenerator::failed() : FailedState This is used for failed responses.

Example

Success Response

This is for success response :

<?php
use Illuminate\Support\Facades\Route;
use Milito\ResponseGenerator\Facades\MilitoResponseGenerator;

Route::get('/', function () {
    return MilitoResponseGenerator::success()
            ->succeeded() // Sets the `Http Status code` field of response to `HTTP_OK` (200).
            ->message("Success response message") // Sets the `message` field of response.
            ->data([
                "body" => "Success response body"
            ]) // Sets the `data` field of response.
            ->send(); // Generates the response as a `json` response.
});

The response should be like this :

{
  "message": "Success response message",
  "success": true,
  "code": 200,
  "data": {
    "body": "Success response body"
  }
}

Failed Response

This is for failed response :

<?php
use Illuminate\Support\Facades\Route;
use Milito\ResponseGenerator\Facades\MilitoResponseGenerator;

Route::get('/', function () {
    return MilitoResponseGenerator::failed()
            ->code(\Illuminate\Http\Response::HTTP_INTERNAL_SERVER_ERROR) // Sets the `Http Status code` field of response to `SERVER_ERROR` (500).
            ->message("Error Response message") // Sets the `message` field of response.
            ->errors(["Yeah this is error"]) // Sets the `error` & the `errors` fields of response.
            ->send(); // Generates the response as a `json` response.
});

The response should be like this :

{
  "message": "Error Response message",
  "success": false,
  "code": 500,
  "error": "Yeah this is error",
  "errors": {
    "all": [
      "Yeah this is error"
    ]
  }
}

Note 1 : If you don't want to show success, code, or errors fields, you can disable them through the config file.

Note 2 : If you want to change the position of the fields, you can change it through the config file.

Functions & Classes

Now, how to handle success response. For example, we use facade to start a response, we set response fields step by step. Now we need to know how to work with these functions and how to generate our success response.

Success Response

SuccessState

After usingMilitoResponseGenerator::success() function to start a success response, we will have an object of SuccessState type. We will have the following functions for SuccessState (This is an object) :

Function	Input	Output	Description
code(int $code)	int status_code	MessageState object	Sets Http code (what ever you want)
succeeded()	void	MessageState object	Sets Http code as HTTP_OK code (200)
created()	void	MessageState object	Sets Http code as HTTP_CREATED code (201)
accepted()	void	MessageState object	Sets Http code as HTTP_ACCEPTED code (202)
updated()	void	SendState object	Sets http code as HTTP_NO_CONTENT code and doesn't need a body (204)

Note : If used updated() function, it means we need no content response. Because of that, the next state is SendState to generate the response.

MessageState

MessageState has these functions :

Function	Input	Output	Description
message(string $message)	string message	DataState object	Sets the message field of response

DataState

DataState has these functions :

Function	Input	Output	Description
data(mixed $data)	mixed data	SendState object	Sets the data field of response
send(array $headers = [])	array headers	JsonResponse object	Generates Response.

Note 1 : mixed input type because we pass array or object or json resources or etc... to our data function.

Note 2 : We can send a response with an empty data.

SendState

SendState is the last step. After that, we use send function to generate a response and return it to client.

Function	Input	Output	Description
send(array $headers = [])	array headers	JsonResponse object	Generates Response.

Failed Response

FailedState

After using MilitoResponseGenerator::failed() function to start a failed response, we will have an object of FailedState type. We will have the following functions for FailedState (This is an object) :

Function	Input	Output	Description
code(int $code)	int status_code	MessageState object	Sets the Http code (what ever you want)

MessageState

MessageState has these functions :

Function	Input	Output	Description
message(string $message)	string message	ErrorState object	Set message field of response

MessageState

MessageState has these functions :

Function	Input	Output	Description
errors(mixed $errors)	mixed message	DataState object	Sets the error & the errors (as object) fields of response
send(array $headers = [])	array headers	JsonResponse object	Generates Response.

Note 1 : mixed input type because we pass array or object or string or etc... to our errors function.

Note 2 : We can generate response without the error & the errors fields value.

DataState

DataState has these functions :

Function	Input	Output	Description
data(mixed $data)	mixed data	SendState object	Sets the data field of response
send(array $headers = [])	array headers	JsonResponse object	Generates Response.

Note 1 : mixed input type because we pass array or object or json resources or etc... to our data function.

Note 2 : We can send a response with an empty data.

Note 3 : Sometimes we need to send data after our request failed. Because of that, we have DataState here.

SendState

SendState is the last step. After that, we use send function to generate a response and return it to client.

Function	Input	Output	Description
send(array $headers = [])	array headers	JsonResponse object	Generates Response.

Publish config

Use the following command to publish the config file to change the response fields name or makes some fields hidden from the response :

php artisan vendor:publish --tag=milito-response-config

Test

Use the following command to run tests:

composer test
