After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

📋 Table of Contents

🚀 Installation

  1. Install via Composer:

  2. Publish the configuration and migration:

    This will publish config/lamet.php and the migration to database/migrations/lamet/.

    Alternatively, you can publish them separately:

  3. Configure your database and cache:

    • Set up your desired database connection in config/database.php (e.g., sqlite, mysql, pgsql). Postgres is recommended

    • Create a new cache store or use an existing one from config/cache.php (e.g., redis).
    • Add and update the .env variables for the new database connection

    [!NOTE] > Quick Setup: Use the provided misc/postgres-docker-compose.yml example to quickly spin up a PostgreSQL container for development and testing.

  4. Run the migration:

    [!IMPORTANT] The 5th step is very important. If you skip this your metrics won't be saved in the database. Also keep in mind that you have to set the frequency lower than the ttl value in config/lamet.php

  5. Schedule periodic flushing: In app/Console/Kernel.php:

    [!TIP] Higher frequency means less granularity, not suitable for realtime metrics but lower memory usage Lower frequency means more granularity, suitable for realtime metrics but higher memory usage Keep it between 5-20 minutes in general.
