ASGI middleware for logging traffic to a SQLite database

See [Logging to SQLite using ASGI middleware](https://simonwillison.net/2019/Dec/16/logging-sqlite-asgi-middleware/) for background on this project.

## Installation

    pip install asgi-log-to-sqlite

## Usage

```python

from asgi_log_to_sqlite import AsgiLogToSqlite

from my_asgi_app import app

app = AsgiLogToSqlite(app, "/tmp/log.db")

```

Requests to your ASGI app will now be logged to the SQLite database file at `/tmp/log.db`.

## Schema

The database used to log requests has one key table - `requests` - and 6 lookup tables: `paths`, `user_agents`, `referers`, `accept_languages`, `content_types` and `query_strings`.

The full schema is as follows:

```sql

CREATE TABLE [paths] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_paths_name

                ON paths (name);

CREATE TABLE [user_agents] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_user_agents_name

                ON user_agents (name);

CREATE TABLE [referers] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_referers_name

                ON referers (name);

CREATE TABLE [accept_languages] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_accept_languages_name

                ON accept_languages (name);

CREATE TABLE [content_types] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_content_types_name

                ON content_types (name);

CREATE TABLE [query_strings] (

   [id] INTEGER PRIMARY KEY,

   [name] TEXT

);

CREATE UNIQUE INDEX idx_query_strings_name

                ON query_strings (name);

CREATE TABLE [requests] (

   [start] FLOAT,

   [method] TEXT,

   [path] INTEGER REFERENCES [paths]([id]),

   [query_string] INTEGER REFERENCES [query_strings]([id]),

   [user_agent] INTEGER REFERENCES [user_agents]([id]),

   [referer] INTEGER REFERENCES [referers]([id]),

   [accept_language] INTEGER REFERENCES [accept_languages]([id]),

   [http_status] INTEGER,

   [content_type] INTEGER REFERENCES [content_types]([id]),

   [client_ip] TEXT,

   [duration] FLOAT,

   [body_size] INTEGER

);
