abstract_flask

A composable toolkit for standing up Flask APIs without repeating yourself. Handles blueprint discovery, CORS, request parsing, endpoint introspection, and route generation — so the only code you write is the code that matters.

Install

pip install abstract_flask

Quickstart

# my_api/__init__.py
from . import routes
from abstract_flask import get_Flask_app

app = get_Flask_app(routes=routes, allowed_origins=["https://yourdomain.com"])

That's it. Blueprints are discovered from any *_bp objects in your routes module, CORS is applied, and introspection endpoints are registered automatically.

Full signature

app = get_Flask_app(
    name="my_api",              # Flask app name (default: caller's __name__)
    routes=routes,              # module to scan for *_bp Blueprints
    bp_list=None,               # or pass blueprints explicitly
    url_prefix="v1",            # prefix for blueprint registration + filtered /endpoints
    allowed_origins=["https://example.com"],
    supports_credentials=True,
)

Running

from abstract_flask import main_flask_start

main_flask_start(app, key_head="MYAPI", env_path=".env")
# reads MYAPI_DEBUG, MYAPI_HOST, MYAPI_PORT from env

Core modules

App factory (abstract_flask.py)

Function	Purpose
get_Flask_app(...)	One-call app factory: blueprints, CORS, logging, introspection
get_bp(name, abs_path)	Create a named Blueprint with a logger
main_flask_start(app)	Run the app using env-driven host/port/debug

Every app gets these endpoints for free:

• GET /endpoints — all registered routes
• GET /<prefix>/endpoints — routes under that prefix
• GET /prefixes — unique top-level route segments

Request utilities (request_utils/)

from abstract_flask.request_utils import get_request_data, required_keys, parse_request

• get_request_data(req) — Returns a dict from JSON body, form data, or query string (checked in that order).
• extract_request_data(req, res_type) — Full extraction: user, IP, headers, cookies, files, metadata. Pass res_type to narrow scope.
• required_keys(keys, req, defaults) — Validate that required keys are present; returns the data dict or a 400 error payload.
• parse_request(req) — Split a request into positional args and kwargs.
• get_spec_kwargs(var_types, args, **kwargs) — Type-coerced argument extraction against a schema.

Route generator (generator/)

Auto-generate Flask endpoints from plain Python files:

from abstract_flask.generator import generate_from_files

source = generate_from_files(
    directory="./my_functions",
    bp_name="auto_bp",
    url_prefix="generated",
)

Every public function becomes a GET/POST endpoint. Async functions are preserved. Pass ?help to any generated endpoint to get parameter introspection via offer_help.

Register routes programmatically against an existing blueprint:

from abstract_flask.generator import register_category

register_category(bp, "math", {
    "add": lambda a, b: a + b,
    "multiply": lambda a, b: a * b,
})
# creates /math/add, /math/multiply

Network utilities (network_utils/)

from abstract_flask.network_utils import get_host_ip, get_user_ip

User utilities (user_utils/)

from abstract_flask.user_utils import get_user_name

Resolves username from the request's .user attribute, falling back to IP-based lookup via UserIPManager.

Dependencies

• flask, flask_cors, werkzeug
