lia-web (renamed to cross-web)

0.3.1 · renamed · verified Sun Apr 12

The `lia-web` package has been renamed to `cross-web`. This entry describes `cross-web`, which provides a unified, framework-agnostic interface for common web framework operations, allowing developers to write code that can easily adapt to various Python web frameworks like FastAPI, Flask, and Django. It is currently in early development. The latest version of `cross-web` is 0.4.1, released on January 9, 2026.

Warnings

breaking The `lia-web` package has been renamed to `cross-web`. Users should migrate to `cross-web` as `lia-web` is no longer maintained and installs an older, deprecated version. Functionality and APIs may differ significantly.
Fix: Uninstall `lia-web` and install `cross-web` using `pip uninstall lia-web && pip install cross-web`.
gotcha The `cross-web` library is in early development. This implies that APIs, functionality, and stability may change frequently without strict backward compatibility guarantees.
Fix: Monitor the official GitHub repository for updates and breaking changes. Pin your dependency versions to specific releases to avoid unexpected breakage.
gotcha Avoid using mutable objects (like lists or dictionaries) as default arguments in function definitions within `cross-web` callbacks or extensions. This can lead to unexpected state sharing and bugs across multiple function calls.
Fix: Use `None` as a default value, and initialize the mutable object inside the function if `None` is provided. E.g., `def my_func(arg, my_list=None): if my_list is None: my_list = []`

Install

pip install cross-web Install cross-web (recommended)
pip install lia-web # This package is deprecated and will install an old version. Install deprecated lia-web

Imports

CrossAdapter
```
from crossweb import CrossAdapter
```
Based on project description; actual primary import may vary as project is in early development.

Quickstart

This quickstart demonstrates a hypothetical initialization of a `CrossAdapter` object from the `crossweb` library. As `cross-web` is in early development and primarily focuses on providing a unified interface for web framework operations, specific code examples are not yet widely available in public documentation. This snippet infers a possible entry point and usage pattern.

import os
from crossweb import CrossAdapter

# Placeholder for framework-agnostic application setup
# In a real scenario, this would integrate with a specific web framework (e.g., Flask, FastAPI)
# and CrossAdapter would provide utilities.

# Example: Initialize an adapter (inferred usage)
try:
    app_adapter = CrossAdapter()
    print("CrossAdapter initialized successfully.")
    
    # Example of a generic operation (inferred)
    # This part is highly speculative without official code examples.
    # print(app_adapter.get_current_request_context())
    
except ImportError:
    print("crossweb library not found. Please install with 'pip install cross-web'.")
except Exception as e:
    print(f"An error occurred during CrossAdapter initialization: {e}")
