flask-apispec-tools 0.2.0

A set of tools to aid in adding APISpec to Flask projects.

Installation

pip install flask-apispec-tools

Configuration

flask-apispec-tools requires the following inside the Flask app config.

[FLASK_APISPEC_TOOLS]
version =
title =
description =
docs_dir =
docs_type =

version	The version of your api.
title	The name of your api.
description	A description of your api.
docs_dir	The directory where api docs are to be stored.
docs_type	The format you want your docs created as. Can be either "json" or "yaml".

Setting Config Values

There are multiple ways to add the config items to the Flask app. See Flask Configuration Handling. While it is recommended to use separate config files or environment variables, flask-apispec-tools allows you to pass configuration values to the init() function. See Configuring flask-apispec-tools with init().

Referencing Other Config Options

Config values can be references to other config options using the format ${section:option}.

[FLASK_APISPEC_TOOLS]
version = ${METADATA:version}
title = ${METADATA:title}
description = ${METADATA:description}
docs_dir = myproj/static/docs
docs_type = json

Initialization

flask_apispec_tools.init(app)

This registers the cli command generate-api-docs with Flask and adds 3 endpoints ( /docs, /docs/json or /docs/yaml, /version) to the app.

Customizing Built-in Endpoints

Adding these endpoints can be disabled or their paths can be changed by passing additional arguments to init().

The example below sets the paths for the docs and docs_json endpoints and disables the version endpoint.

flask_apispec_tools.init(
    app,
    docs_endpoint='/api/docs',
    docs_json_endpoint='/api/docs/json',
    version_endpoint=False
)

APISpec Plugins

A list of apispec plugins can be passed to init() and they will be given to the APISpec object. See APISpec Using Plugins. You do not need to give init() the FlaskPlugin.

flask_apispec_tools.init(
    app,
    plugins=[MarshmallowPlugin(), MyCustomPlugin()]
)

Configuring flask-apispec-tools with init()

flask-apispec-tools can be configured by passing a dictionary of config values to init(). This will override any existing configuration values.

flask_apispec_tools.init(
    app,
    config_values={
        'docs_dir': '/docs',
        'docs_type': 'json'
    }
)

Generating API Docs

flask generate-api-docs

Options

-a, --all Include enpoints marked 'Exclude From Spec'.

Excluding Endpoints

Endpoints can be excluded from docs by adding Exclude From Spec at the top of the docstring. This exclusion can be ignored using -a or --all with flask generate-api-docs.

class MyEndpoint(MethodView):
    """Exclude From Spec"""

    def get(self):
        ...

Built-in Endpoints

endpoint	description	query parameters
/docs	Display docs with Swagger UI.	version (optional): Which version of the API docs to get.
/docs/json	Get docs as JSON.	version (optional): Which version of the API docs to get.
/docs/yaml	Get docs as YAML.	version (optional): Which version of the API docs to get.
/version	Get the API version.
