# drf-standardized-errors — Standardize your API error responses.

License: permissive · Maintenance: active · Downloads: 510.4K/mo

## What it is and what it does

DRF Standardized Errors is an exception handler for Django REST Framework that intercepts API errors and reformats them into a consistent JSON structure. Instead of DRF's default varied error responses, it normalizes all 4xx and 5xx errors into a unified format with a type field (validation_error, client_error, or server_error), an errors array containing code, detail, and attr fields, and optional field-level attribution for validation failures.

The package is designed to be plugged into DRF's exception handling pipeline via a single settings change. It handles nested serializers and ListSerializer errors, integrates with error monitoring tools like Sentry, and offers customization hooks to override specific aspects of error handling without rewriting the entire handler. It does not intercept middleware-level errors or unhandled exceptions in debug mode by default.

Use it for:

- Standardize validation error responses across all endpoints so clients parse a consistent structure.
- Provide field-level error attribution (attr field) to help frontend forms display errors next to the right inputs.
- Integrate with Sentry or similar error monitoring to receive errors in a predictable format.
- Build API documentation that documents a single error response schema instead of multiple formats.
- Customize error codes and messages globally without modifying individual serializers or views.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Converts all Django REST Framework API error responses (4xx and 5xx) into a standardized JSON format with consistent error structure, type classification, and field attribution.

Yes. The package is actively maintained, has no known vulnerabilities, low install friction, and solves a real pain point in DRF development—inconsistent error response formats. It's particularly valuable if you're building client-facing APIs or integrating with error monitoring. Install it if you want predictable, standardized error responses across your DRF project.

## Install

pip install drf-standardized-errors
uv add drf-standardized-errors
poetry add drf-standardized-errors

## Installing drf-standardized-errors

Before you install: Low friction: pure Python wheel with only django and djangorestframework as runtime dependencies. Actively maintained with recent releases; last commit 2026-07-13 and 347 repository stars indicate ongoing support.

License in practice: MIT licensed under permissive terms, allowing commercial and private use with minimal restrictions.

Quickstart:

pip install drf-standardized-errors

# In settings.py INSTALLED_APPS:
INSTALLED_APPS = ["drf_standardized_errors"]

# In REST_FRAMEWORK settings:
REST_FRAMEWORK = {
    "EXCEPTION_HANDLER": "drf_standardized_errors.handler.exception_handler"
}

Requires Django >= 3.2 and djangorestframework >= 3.12; only handles errors that reach DRF API views, not middleware-level errors.

Verify before relying:

- Whether the package handles all custom exception types or only DRF built-ins.
- Performance overhead of exception transformation on high-traffic APIs.
- Compatibility with async DRF views or ASGI deployments.
