Upgrade Guide

This is the recommended configuration for API Platform 3.2. We review each of these changes in this document.

api_platform:
    title: Hello API Platform
    version: 1.0.0
    formats:
        jsonld: ['application/ld+json']
    docs_formats:
        jsonld: ['application/ld+json']
        jsonopenapi: ['application/vnd.openapi+json']
        html: ['text/html']
    defaults:
        stateless: true
        cache_headers:
            vary: ['Content-Type', 'Authorization', 'Origin']
        extra_properties:
            standard_put: true
            rfc_7807_compliant_errors: true
    event_listeners_backward_compatibility_layer: false
    keep_legacy_inflector: false

We noticed that API Platform was enabling json by default because of our OpenAPI support. We introduced the new application/vnd.openapi+json. Therefore if you want json you need to explicitly handle it:

formats: 
    json: ['application/json']

You can also remove documentations you’re not using via the new docs_formats.

A new option error_formats is also used for content negotiation.

For new users we recommend to use

event_listeners_backward_compatibility_layer: false

This allows API Platform to not use http kernel event listeners. It also allows you to force options like read: true or validate: true. This simplifies use cases like validating a delete operation Event listeners will not get removed and are not deprecated, they’ll use our providers and processors in a future version.

We’re switching to symfony/string inflector, to keep using doctrine/inflector use:

keep_legacy_inflector: true

We strongly recommend that you use your own inflector anyways with a PathSegmentNameGenerator.

defaults:
    extra_properties:
        rfc_7807_compliant_errors: true

As this is an extraProperties it’s configurable per resource/operation. This is improving the compatibility of Hydra errors with JSON problem. It also enables new extension points on Errors such as Error provider and Error Resource.
