Laravel: Facebook EdgeRank Algorithm for Laravel

This package is a simple and flexible implementation of the Facebook EdgeRank algorithm for Laravel. Ideal for newsfeeds like Twitter, Facebook, LinkedIn, etc. Use the EdgeRank algorithm to sort posts and similar content based on factors such as likes, comments, shares, and time. The configuration makes it easy to manage the weighting of different parameters.

Installation and setup

Installation with Composer

composer require nikolajlovenhardt/laravel-edgerank

Publish resources

Config

php artisan vendor:publish --tag="edgerank-config"

Migrations

php artisan vendor:publish --tag="edgerank-migrations"

Use-cases and demos

Sort posts using default weights

use LaravelEdgeRank\Builders\EdgeRankBuilder;

$posts = EdgeRankBuilder::make()
    ->get();

Limits and offsets

Simple pagination

Paginate with a simple limit and offset

use LaravelEdgeRank\Builders\EdgeRankBuilder;

$posts = EdgeRankBuilder::make()
    ->limit(50)
    ->offset(100)
    ->get();

Cursor

Do you need to paginate using ids? No worries, we got your back

use LaravelEdgeRank\Builders\EdgeRankBuilder;

$posts = EdgeRankBuilder::make()
    ->after(100, 'id') // Get older posts than #100
    ->get();

Custom query

Use the $builder->query() method to access the query builder before fetching the results. This allows you to add custom query code still utilizing the EdgeRank-sort.

use LaravelEdgeRank\Builders\EdgeRankBuilder;
use App\Models\Feed\Item;

$friendIds = [1, 2, 3, 4];

$posts = EdgeRankBuilder::make(Item::class)
    ->query()
    ->where(function ($query) use ($friendIds) {
        $query->whereIn('user_id', $friendIds)
        
        $query->orWhereHas('user', function () {
            $query->where('is_public', '=', true)
        });
    })
    ->get();

Custom model / Override config

Use a custom model without configuration using the EdgeRankBuilder::make() method, and add custom config using weights()and options()-methods.

use LaravelEdgeRank\Builders\EdgeRankBuilder;
use App\Models\Feed\Item;

$posts = EdgeRankBuilder::make(Item::class)
    ->weights([
        'likes' => 10,
        'hates' => 2,
        'customRelation' => 1.5, // Item->customRelation(): HasMany
    ])
    ->get();
