PHP Json Feed

This library provides a way to generate JSON feeds, a format recently introduced to the community.

Installation via Composer

$ composer require mateusjatenee/php-json-feed

Laravel Installation

On your config/app.php file, register the service provider:

'providers' => [
    ...
    Mateusjatenee\JsonFeed\JsonFeedServiceProvider::class,
];

And on the aliases array, register the facade:

'aliases' => [
    ...
    'JsonFeed' => Mateusjatenee\JsonFeed\Facades\JsonFeed::class,
];

Usage

The library is really simple to use and actually does not depend on Laravel itself, though it allows you to use a config file (not yet). It automatically filters formats the JSON and removes any unnecessary property.

If you're not using Laravel, jump to this part.

How to use it? Let's take the following JSON as an example:

{
    "title": "My JSON Feed test",
    "home_page_url": "https://mguimaraes.co",
    "feed_url": "https://mguimaraes.co/feeds/json",
    "author": {
        "url": "https://twitter.com/mateusjatenee",
        "name": "Mateus Guimarães"
    },
    "icon": "https://mguimaraes.co/assets/img/icons/apple-touch-icon-72x72.png",
    "favicon": "https://mguimaraes.co/assets/img/icons/favicon.ico",
    "version": "https://jsonfeed.org/version/1",
    "items": [
        {
            "content_text": "Great book. It's the best book.",
            "date_published": "2017-05-22T00:00:00+00:00",
            "title": "1984",
            "author": {
                "name": "Mateus",
                "url": "https://mguimaraes.co"
            },
            "content_html": "<p>Great book. It's the best book.</p>",
            "id": "abc123",
            "url": "https://mguimaraes.co",
            "external_url": "https://laravel.com",
            "date_modified": "2017-05-22T00:00:00+00:00"
        },
        {
            "content_text": "Great book. It's the best book.",
            "date_published": "2017-05-22T00:00:00+00:00",
            "title": "1984",
            "author": {
                "name": "Mateus",
                "url": "https://mguimaraes.co"
            },
            "content_html": "<p>Great book. It's the best book.</p>",
            "id": "abc123",
            "url": "https://mguimaraes.co",
            "external_url": "https://laravel.com",
            "date_modified": "2017-05-22T00:00:00+00:00"
        }
    ]
}

To do this, first you need to set the config — you can set it at any time during runtime (on a Service Provider, perhaps) using the Facade or instantiating it through the container (i.e app('jsonFeed'))

<?php

use Mateusjatenee\JsonFeed\Facades\JsonFeed;

$config = [
    'title' => 'My JSON Feed test',
    'home_page_url' => 'https://mguimaraes.co',
    'feed_url' => 'https://mguimaraes.co/feeds/json',
    'author' => [
        'url' => 'https://twitter.com/mateusjatenee',
        'name' => 'Mateus Guimarães',
    ],
    'icon' => 'https://mguimaraes.co/assets/img/icons/apple-touch-icon-72x72.png',
    'favicon' => 'https://mguimaraes.co/assets/img/icons/favicon.ico',
];

JsonFeed::setConfig($config);

Then, you need to set the items. The items may be an array of objects or a collection of objects. We're gonna talk about this a bit later.

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use JsonFeed;

class JsonFeedController extends Controller
{
    public function index()
    {
        $posts = App\Post::all();

        return JsonFeed::setItems($posts)->toJson();
    }
}

All at once

Alternatively, you may do all at once, specially if you are not using Laravel.

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use JsonFeed;

class JsonFeedController extends Controller
{
    public function index()
    {
        $posts = App\Post::all();

        $config = [
            'title' => 'My JSON Feed test',
            'home_page_url' => 'https://mguimaraes.co',
            'feed_url' => 'https://mguimaraes.co/feeds/json',
            'author' => [
                'url' => 'https://twitter.com/mateusjatenee',
                'name' => 'Mateus Guimarães',
            ],
            'icon' => 'https://mguimaraes.co/assets/img/icons/apple-touch-icon-72x72.png',
            'favicon' => 'https://mguimaraes.co/assets/img/icons/favicon.ico',
        ];

        return JsonFeed::start($config, $posts)->toJson();
    }
}

How to get each item properties

It's really simple. An item only requires an id, the other fields are optional but highly recommended. First of all, your model (or any other object that is gonna be used on the json feed) needs to implement \Mateusjatenee\JsonFeed\Contracts\FeedItemContract and it's only method - getFeedId(). It should return an unique Id relative to that item. Below is a list of each method and what it does.

Method	What it does	Expects
`getFeedId`	Gets a unique ID	string
`getFeedUrl`	Gets the URL of the resource	string
`getFeedExternalUrl`	Gets the URL of the page elsewhere	string
`getFeedTitle`	Gets the resource title	string
`getFeedContentHtml`	Gets the HTML of the content	string
`getFeedContentText`	Gets the text of the content	string
`getFeedSummary`	Gets the resource summary	string
`getFeedImage`	Gets the resource image	string
`getFeedBannerImage`	Gets the resource banner image	string
`getFeedDatePublished`	Gets the resource published date. The lib automatically converts it to the specific date format.	string
`getFeedDateModified`	Gets the resource modified date. The lib automatically converts it to the specific date format.	string
`getFeedAuthor`	Gets the resource author. If not specified, the same as the top level one is going to be used.	string
`getTags`	Gets the resource tags.	array

You may find all accepted methods on the JSON Feed Spec
