README

This PostHog (HogQL) Laravel Query Builder package enables you to interact with PostHog's HogQL API using Laravel's query builder. This package simplifies the process of building and executing analytical queries, allowing you to leverage Laravel's intuitive query syntax while working with PostHog's powerful data analytics platform.

Features

• Familiar Syntax: Use Laravel's query builder syntax to construct complex queries.
• Secure Access: Validate and restrict access to specific tables within PostHog.
• Seamless Integration: Execute queries and retrieve results directly from PostHog.
• Configurable Aliases: Easily map and alias table and column names for better readability.
• Eloquent Metrics: Easily integrate and use with moirei/eloquent-metrics.

Installation

composer require moirei/hogql

Publish the config (optional).

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

Setup

After installation, you'll need to obtain your Product ID and a personal API key. This key will need atleast query:read scope.

Update your .env file with POSTHOG_PRODUCT_ID and POSTHOG_API_TOKEN accordingly.

Usage

use MOIREI\HogQl\Facade as HogQl;
...

HogQl::select(['event_name', 'COUNT(*) as event_count'])
                ->whereBetween('timestamp', ['2024-01-01 12:00:00', '2024-07-28 10:15:39'])
                ->groupBy('event_name')
                ->orderBy('event_count', 'DESC')
                ->get();

Note: the get() operation always transforms the raw result. E.g. the query above returns a collection of arrays with event_name and event_count keys/values.

Extended usage

Get a DB Query Builder instance:

$query = HogQl::query();
// OR
$query = HogQl::query('some_other_table');

$result = $query->get();

Start a query with select statement:

$query = HogQl::select('properties.$os as os')->where('os', 'iOS');
$result = $query->count();

Referencing aliases:

Setup aliases in config:

// config/hogql.php
...
    'aliases' => [
        'device' => 'properties.$device',
        'os' => 'properties.$os',
        ...
    ],

Reference them via selects:

$query = HogQl::select(['device', 'os']);
$result = $query->get();

Get an Eloquent Query Builder instance:

Returns eloquent model instances.

$query = HogQl::model();
// OR
$query = HogQl::eloquent();

$result = $query->select(['properties.$current_url', 'properties.$device'])->get();

Parse a query string:

$query = HogQl::parse('SELECT event FROM events');
$result = $query->where('properties.my_user', $user->id)->count();

Get the results of a string query:

$response = HogQl::get('SELECT event, COUNT() FROM events GROUP BY event ORDER BY COUNT() DESC');

Get the raw results of a string query:

Returns the raw original HogQLQueryResponse response.

$response = HogQl::getRaw('SELECT event, COUNT() FROM events GROUP BY event ORDER BY COUNT() DESC');

With moirei/eloquent-metrics:

moirei/eloquent-metrics is Chartjs compatible.

$query = HogQl::eloquent()->where('event', '$pageview');

$metrics = Trend::make()
            ->name('Page views')
            ->period('week')
            ->sumByDays($query);
