Symfony Profiler Response Bundle

Dev-only Symfony bundle that adds a "Response Body" panel to the Web Profiler, showing JSON/text response payloads with size limits and sensible guards.

Features

• Captures response body for textual and JSON-like MIME types
• Skips streamed/binary responses to avoid breaking downloads
• Truncates large payloads (default 256 KB) to protect the toolbar
• Pretty-prints JSON when possible

Installation

1. Install the bundle:

      composer require --dev savinmikhail/symfony-profiler-response-bundle

2. Copy the configuration file:

      cp vendor/savinmikhail/symfony-profiler-response-bundle/config/packages/response_profiler.yaml config/packages/

3. The bundle will be automatically registered by Symfony Flex.

Usage

• In the Web Profiler, open any request and look for the new "Response Body" tab.
• The toolbar badge shows MIME and size; the panel shows headers and the (pretty-printed) body, truncated if oversized.

Appearance

Notes

• This bundle is designed for development. Do not enable in production.
• Streamed and binary responses are ignored.
• Pretty-printing of very large JSON may be skipped when payloads are huge.
