tidewave 0.2.0

Tidewave Web for Django, FastAPI, and Flask

Tidewave

Tidewave is the coding agent for full-stack web app development. Integrate Claude Code, OpenAI Codex, and other agents with your web app and web framework at every layer, from UI to database. See our website for more information.

This project supports Django, FastAPI, and Flask. It can also be used as a standalone Model Context Protocol (MCP) server for your editors.

Installation

Django

Add tidewave[django] as a dependency to your pyproject.toml:

"tidewave[django]",

Then open up your settings.py and add the following after your MIDDLEWARE and INSTALLED_APPS definition:

if DEBUG:
    INSTALLED_APPS.insert(0, "tidewave.django.apps.TidewaveConfig")
    MIDDLEWARE.insert(0, 'tidewave.django.Middleware')

If you are using Jinja2, you need to add our extension too (preferably in DEBUG mode only):

JINJA2_ENVIRONMENT_OPTIONS = {
    "extensions": [
        "tidewave.jinja2.Extension"
    ],
}

Now make sure Tidewave is installed and you are ready to connect Tidewave to your app.

Settings

• TIDEWAVE["allow_remote_access"] - Whether to allow remote connections (default False)
• TIDEWAVE["team"] - Enable your Tidewave Team configuration, such as TIDEWAVE = {"team": {"id": "dashbit"}}

Note Tidewave only runs in DEBUG mode.

Flask

Add tidewave[flask] as a dependency to your pyproject.toml:

"tidewave[flask]",

Now, in your application definition, you can initialize the Tidewave class and pass your Flask application to init_app:

if app.debug:
    from tidewave.flask import Tidewave
    tidewave = Tidewave()
    tidewave.init_app(app)

Note Tidewave only runs when app.debug is True. Therefore, remember to start your dev server with the --debug flag. If you are setting app.debug programatically, remember to do so before you call tidewave.init_app.

Now make sure Tidewave is installed and you are ready to connect Tidewave to your app.

Configuration

When initializing Tidewave(), the following options are supported:

• allow_remote_access: allow remote connections when True (default False)
• team: enable Tidewave Web for teams

Tidewave will automatically detect if your Flask application is using SQLAlchemy and Jinja2 and configure them automatically.

FastAPI

Tidewave Web is currently not supported for FastAPI.

Add tidewave[fastapi] as a dependency to your pyproject.toml:

"tidewave[fastapi]",

Now, in your application definition, you can initialize the Tidewave class and pass your FastAPI application to install. Note that you only want to do this in development mode:

# Your preferable way of detecting dev mode.
is_dev = os.environ.get("RUN_MODE", None) == "development"

if is_dev:
    from tidewave.fastapi import Tidewave
    tidewave = Tidewave()
    tidewave.install(app)

If you are using Jinja2, you need to add our extension too:

if is_dev:
    # ...

    from tidewave.jinja2 import Extension
    templates.env.add_extension(Extension)

If you are using SQLAlchemy, then you need to pass your Base class and the underlying engine as arguments to install:

tidewave.install(app, sqlalchemy_base=Base, sqlalchemy_engine=engine)

Note: when using SQLModel, you should set sqlalchemy_base=SQLModel.

Now make sure Tidewave is installed and you are ready to connect Tidewave to your app.

Configuration

When initializing Tidewave(), the following options are supported:

• allow_remote_access: allow remote connections when True (default False)
• team: enable Tidewave Web for teams

Available tools

• execute_sql_query - executes a SQL query within your application database, useful for the agent to verify the result of an action (if Django or SQLAlchemy are configured)

• get_docs - get the documentation for a given module/class/method. It consults the exact versions used by the project, ensuring you always get correct information

• get_logs - reads logs written by the server

• get_models - lists all modules in the application and their location for quick discovery (if Django or SQLAlchemy are configured)

• get_source_location - get the source location for a given module/class/method, so an agent can directly read the source skipping search

• project_eval - evaluates code within the web server itself, giving the agent access to your runtime, dependencies, and in-memory data

Troubleshooting

Content security policy

If you have enabled Content-Security-Policy, Tidewave will automatically enable "unsafe-eval" under script-src in order for contextual browser testing to work correctly. It also disables the frame-ancestors directive.
