FAQ

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.

Installation

Step 1: Install via Composer

Run the following command in your terminal:

bash composer require teksite/handler

Step 2: Register the Service Provider

For Laravel > 9

Add the service provider to the bootstrap/providers.php file:

Note: Laravel 5.5 and above supports auto-discovery, so this step is not required for newer versions.

Features

Simplify exception handling with ServiceWrapper

Teksite\Handler\Actions\ServiceWrapper

Basic Usage

Advanced Configuration

Event Dispatching

The run() method accepts two optional parameters to dispatch custom events:

Example:

Event Classes Configuration:

Define your event classes in config/handler.php:

Note: Events are resolved using Laravel's service container, so dependency injection is fully supported in your event constructors.

ServiceResult Wrapper

By default, the output of both do() and ifFailed() is wrapped in a ServiceResult instance for consistent return values:

Disable wrapping:

Streamlined Database Query Methods

Teksite\Handler\Facade\FetchData (backed by Teksite\Handler\Services\FetchDataService)

FetchDataService is resolved from the container (it depends on the current Request), so use the FetchData facade or dependency injection - it is not a static class.

Example with ServiceWrapper

Standalone Usage

Fluent Usage

Every option can also be set fluently before calling get(), which is handy when the same query is built up conditionally:

Method Parameters

Search with Operators:

Once you're done with a shared/injected instance, resetOnly(), resetWith(), resetWithCount(), resetSearch(), resetOrdering(), resetPagination() and reset() clear the fluent state so it can be reused for a different query. forgetColumnsCache($model) and forgetAllColumnsCache() clear the cached column listing used to validate orderBy() input (this is also flushed automatically after migrations run).

HTTP Response Helper

Event System

How It Works

The ServiceWrapper automatically dispatches events when configured:

  1. Success Events - Triggered when the do() closure executes without errors
  2. Failure Events - Triggered when an exception is caught

Custom Event Example

Create your event class:

Configure in config/handler.php:

Use in your codes:

Control event dispatch per method call:
