Apify

A pretty library to help developers build RESTful APIs lightly, quickly and properly even without writing code.

It's always easy to customize to suit any need such as defining data relationships, authorization, caching, communicating or integrating into other systems.

Features

• Serves RESTful APIs for any MySql database
  • Pagination
  • Sorting
  • Selection
  • Grouping, Having
  • Filtering
  • Relationships
  • Metadata
• Supports Event Bus

Use HTTP clients like Postman to invoke RESTful API calls.

Combine with API Gateway is also recommended to build a completely development environment for microservice.

Installation

Apify is packed as a composer package. So it's installed quickly in 2 steps

1. Require the composer package

   composer require megaads/apify

2. Register the provider:

   Megaads\Apify\ApifyServiceProvider

System requirements

• PHP: >= 5.6
• Laravel/ Lumen Framework: 5.4.*
• MySQL
• Message queue server: optional

API Overview

| HTTP Method | API URL | Description | For example |-------------|----------------------------------|-----------------------|--------------------------------- | GET | /api/entity | List all records of table that match the query | curl http://my-api.com/api/user?filters=age>20 | | GET | /api/entity/:id | Retrieve a record by primary key :id | curl http://my-api.com/api/user/123 | | POST | /api/entity | Insert a new record, bulk inserting is also avaiable | curl -X POST http://my-api.com/api/user -d '[{"username":"user1", "age":"20"},{"username":"user2", "age":"25"}]' -H "Content-Type: application/json" | | PUT | /api/entity/:id | Replaces existed record with new one | curl -X PUT http://my-api.com/api/user/123 -d '{"id":"123", "username":"user1", "age":"20"}' -H "Content-Type: application/json" | | PATCH | /api/entity/:id | Update record element by primary key | curl -X PATCH http://my-api.com/api/user/123 -d '{"age":"21"}' -H "Content-Type: application/json" | | DELETE | /api/entity/:id | Delete a record by primary key | curl -X DELETE http://my-api.com/api/user/123 | | DELETE | /api/entity | Delete bulk records that match the query | curl -X DELETE http://my-api.com/api/user?filters=age>100 | | POST | /api/upload | Upload a file | curl -X POST http://my-api.com/api/upload -H "Content-Type: multipart/form-data" -F "data=@song.mp3"

Pagination

| Parameter | Required | Default | Description | |-------------|-------------|------------|------------------------------------------------------------------| | page_id | No | 0 | Page index, start at 0 | page_size | No | 50 | Number of rows to retrieve per page

/api/post?page_id=2&page_size=20

Sorting

Order by multiple columns using sorts parameter

Sort ascending

/api/post?sorts=user_id

Sort descending

/api/post?sorts=-created_at

Sort by multiple columns

/api/post?sorts=user_id,-created_at

Selection

Select columns from the records using fields parameter. SQL aggregate functions such as COUNT, MAX, MIN, SUM, AVG, SQL aliases are also available

/api/post?fields=id,content,user_id,sum(view_count) as view_sum

Group By

Group the result-set by one or more columns using groups parameter and combine with aggregate functions using Selection

/api/post?fields=user_id,sum(view_count)&groups=user_id

Filtering

| Operator | Condition | For example
|--------------|--------------------|---------------------------------- | = | Equal to | /api/post?filters=user_id=1 | != | Not equal | /api/post?filters=user_id!=1 | > | Greater | /api/post?filters=user_id>1 | >= | Greater or equal | /api/post?filters=user_id>=1 | < | Less | /api/post?filters=user_id<1 | <= | Less or equal | /api/post?filters=user_id<=1 | ={} | In | /api/post?filters=user_id={1;2;3} | !={} | Not in | /api/post?filters=user_id!={1;2;3} | =[] | Between | /api/post?filters=user_id=[1;20] | !=[] | Not between | /api/post?filters=user_id!=[1;20] | ~ | Like | /api/post?filters=title~hello | !~ | Not like | /api/post?filters=title!~hello

Apify supports filtering records based on more than one AND, NOT condition by using comma. For example:

/api/post?filters=user_id=1,status={enabled;pending},tile~hello,view_count!=null

Complex conditions that combine AND, OR and NOT will be available soon.

Entity conventions

Apify works by a simple mechanism, looking for a model class that correspond to the API entity, otherwise the API entity will be matched to a suitable DB table. That means no model class is required to create, do it only in the case of defining relationships, customizing.

So API entity name should follow one of the conventions:

• The API entity name is the same as a model class name

• Or the API entity name in snake_case that correspond to a model class with the name in CamelCase

• Or the API entity name is the same as a DB table name

Relationships

Apify is packed into a Laravel/ Lumen package so relationships also are defined as methods on Eloquent model classes.

See Laravel docs for details: https://laravel.com/docs/5.6/eloquent-relationships

Let's consider the following relationship definations:

• A Nation has many City (one-to-many relationship)

namespace App\Models;
class Nation extends \Apify\Models\BaseModel {
    protected $table = 'location_nation';
    public function cities() {
        return $this->hasMany('App\Models\City', 'nation_id', id);
    }
}

• A City belongs to a Nation (many-to-one relationship)
• A City has many District (one-to-many relationship)

namespace App\Models;
class City extends \Apify\Models\BaseModel {
    protected $table = 'location_city';
    public function nation() {
        return $this->belongsTo('App\Models\Nation', 'nation_id');
    }
    public function districts() {
        return $this->hasMany('App\Models\District', 'city_id', id);
    }
}

• A District belongs to a City (many-to-one relationship)

namespace App\Models;
class District extends \Apify\Models\BaseModel {
    protected $table = 'location_district';
    public function city() {
        return $this->belongsTo('App\Models\City', 'city_id');
    }
}    

Selection on relationships

Apify provides the ability to embed relational data into the results using embeds parameter

For example

/api/nation?embeds=cities

/api/city?embeds=nation,districts

/api/district?embeds=city

Even nested relationships

/api/nation?embeds=cities.districts

/api/district?embeds=city.nation

Filtering on relationships

/api/city?filters=nation.location_code=EU,districts.name~land

Metric

metric=get (by default): Retrieve all records that match the query

/api/post

or

/api/post?metric=get

Response format

{
    "meta": {
        "has_next": true,
        "total_count": 100,
        "page_count": 2,
        "page_size": 50,
        "page_id": 0
    },
    "result": [],
    "status": "successful"
}

metric=first: Retrieve the first record that matchs the query

/api/post?metric=first

Response format

{    
    "result": {},
    "status": "successful"
}

metric=count: Retrieve the number of records that match the query

/api/post?metric=count

Response format

{    
    "result": 50,
    "status": "successful"
}

metric=increment/ decrement: Provides convenient methods for incrementing or decrementing the value of a selected column

/api/post?metric=increment&fields=view_count

Response format

{    
    "result": 1,
    "status": "successful"
}

Event Bus
