# zope.browserresource — Browser resources implementation for Zope.

License: unclear · Maintenance: active · Downloads: 131.5K/mo

## What it is and what it does

zope.browserresource is a Zope Toolkit component that implements a registration and serving system for static browser resources—files like images, stylesheets, and scripts. Resources are registered under symbolic names via ZCML configuration directives, decoupling their logical identity from their physical filesystem location. The package handles directory-based resource publishing, internationalization, and HTTP ETag support for caching.

The package is tightly integrated with the Zope Toolkit ecosystem and depends on 10 other Zope packages (zope.component, zope.configuration, zope.interface, zope.schema, zope.traversing, and others). It is maintained as part of the Zope Toolkit project and is not designed for reuse outside a Zope application context. Current support covers Python 3.9–3.13 on CPython and PyPy.

Use it for:

- Register CSS, JavaScript, and image files under symbolic names in a Zope application to decouple resource URLs from filesystem paths.
- Serve internationalized static resources (e.g., locale-specific images or stylesheets) through a unified resource interface.
- Publish a directory of static assets with automatic file-type-based resource factory selection and forbidden-name filtering.
- Integrate HTTP ETag generation for static resources to enable browser caching and conditional requests in Zope-based web applications.

## Worth the install?

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

Registers and serves static browser resources (images, CSS, JavaScript) under symbolic names via ZCML directives, with support for internationalization and directory-based resource publishing.

Yes, if you are building or maintaining a Zope Toolkit–based application and need to manage static browser resources. No, if you are working outside the Zope ecosystem—the package is explicitly not reusable without the full Zope Toolkit stack. The package is actively maintained, has no known vulnerabilities, and supports modern Python versions, but its utility is confined to Zope projects.

## Install

pip install zope-browserresource
uv add zope-browserresource
poetry add zope-browserresource

## Installing zope.browserresource

Before you install: Low friction install with a wheel available. Active maintenance; latest release 336 days ago with support for Python 3.9–3.13. Depends on 10 Zope Toolkit packages, which will pull in a substantial dependency tree.

License in practice: Licensed under ZPL-2.1 (Zope Public License). License treatment is marked unclear in the fact sheet; review the license terms before use in proprietary or copyleft-sensitive projects.

Quickstart:

pip install zope.browserresource

from zope.browserresource.interfaces import IResourceFactory
from zope.component import adapter, provideAdapter

@adapter(IResourceFactory)
def my_resource_factory(context):
    pass

Requires Python >=3.9. Designed to work within a Zope Toolkit environment; standalone use outside a Zope application is not practical.

Verify before relying:

- Whether the package can be used independently or requires a full Zope application stack to be functional.
- Specific details on how ZCML directives are configured and what additional setup is required beyond installation.
