# Upgrade Guide
# Upgrading to 2.x from 1.x
Version 2.0 adds support for PHP 8.1, and supports both Laravel 8 and 9. Although we had to make some breaking changes to support PHP 8.1, these will not affect the majority of applications. You should therefore find you can upgrade very quickly to the new version.
This chapter provides details of the main changes that in theory could affect applications.
# Updating Dependencies
# Laravel Version
If you are still on Laravel 8, the minimum supported version is now
Ensure you are on at least this version before upgrading.
# Composer Dependencies
To upgrade, first run the following commands:
composer require laravel-json-api/laravel --no-update composer require laravel-json-api/testing --dev --no-update
Then if you have installed any of the following optional packages, run the appropriate command from the following:
composer require laravel-json-api/hashids --no-update composer require laravel-json-api/non-eloquent --no-update composer require laravel-json-api/cursor-pagination --no-update composer require laravel-json-api/boolean-softdeletes --no-update
Then finally run the following command to updated all the dependencies:
composer up laravel-json-api/* cloudcreativity/*
# PHP Return Types
PHP is beginning to transition to requiring return type definitions on PHP
methods such as
offsetSet, etc. In light of this, Laravel
JSON:API has implemented these return types in its code base. Typically,
this should not affect user written code; however, if you are overriding one
of these methods by extending Laravel JSON:API's classes, you will need to add
these return types to your own application.
Server classes had a protected
$app property, that you could use
to access the application instance. This property is now private. If you are
accessing it via
$this->app in your
Server class, you should now use the
$this->app() method instead.
# Eloquent Fields
PHP 8.1 introduced
readonly as a keyword. Previously the Laravel JSON:API
Eloquent package had both an interface and a trait called
ReadOnly. We have
therefore had to rename this interface and trait. Both are now called
You are only likely to be using either of these if you have written your own field classes. In which case, you need to make the following changes:
When upgrading the testing package, we removed some methods that were marked as deprecated some time ago. These methods were also not documented in the testing chapters, so hopefully you have not been using them.
The removed methods are documented here, just in case:
