View.py

Quickstart


$ pip install -U view.py


Breaking Change

The `body` parameter in `Response` is now required. For example, the following code **does not** work on Alpha 9:

py
from view import new_app, Response

app = new_app()

app.get("/")
def index():
res = Response()
return res

app.run()


What's New?

- Added the `context` decorator and the `Context` type
- Added the `headers` parameter to functions on `TestingContext`
- Added `Route.middleware`
- Added `route` and `App.route`
- Added docstrings to router functions
- Added the `JSON` response class
- Added the `custom` body translate strategy
- Added the `extract_path` utility
- Added the `view build` command
- Added `App.template`
- Added `compile_type` and `TCValidator`
- Added `markdown` and `App.markdown`
- Added the `Error` class
- Added the `error_class` parameter to both `new_app` and `App`
- Added the `ERROR_CODES` constant

Bug Fixes

- Fixed syntax errors in `view init`
- Fixed `template` attribute with the `view` template renderer

Other Changes

- Modified some behavior of automatic route inputs
- Routes with equivalent paths but different methods now return `405 Method Not Allowed` when accessed
- Route errors now display the error message when `dev` is `True`
- Changed exception rendering in route errors to use the `rich` renderer
