dhis2w-browser 0.21.0

Playwright-based helpers for DHIS2 UI automation.

dhis2w-browser

Playwright-based helpers for DHIS2 UI automation. Separate from dhis2w-client so API-only callers never pull in Chromium.

Install

uv add 'dhis2w-cli[browser]'            # pulls dhis2w-browser alongside the main CLI
playwright install chromium           # one-off; pulls the actual browser driver

Library-only consumers (no CLI) can install dhis2w-browser on its own.

Surface

The CLI lives on the main d2w entry point as a plugin; there's no separate dhis2w-browser binary. Workflows mount under d2w browser <subcommand>:

d2w browser pat --url http://localhost:8080 --username admin --password district
d2w browser dashboard screenshot --output-dir /tmp/out --only <uid>
d2w browser viz screenshot --output-dir /tmp/out --only <uid>
d2w browser map screenshot --output-dir /tmp/out --only <uid>

Library callers import from dhis2w_browser directly:

Entry point	Purpose
dhis2w_browser.logged_in_page(url, username, password)	Async context manager yielding a (BrowserContext, Page) tuple logged into DHIS2 via the React login form.
dhis2w_browser.session_from_cookie(url, jsessionid)	Fast-path variant — inject a pre-minted JSESSIONID instead of driving the login form.
dhis2w_browser.create_pat(url, username, password, options=...)	Mint a Personal Access Token V2 (POST /api/apiToken) through an authenticated browser session. Returns the d2p_... token string. DHIS2 only returns the token value once — store it immediately.
dhis2w_browser.drive_oauth2_login(profile_name, *, username, password)	Run d2w profile login <name> --no-browser end-to-end — spawns the CLI, reads the authorize URL from its stderr, and drives Chromium through the DHIS2 React login + Spring AS consent screen + loopback redirect. Returns an OAuth2LoginResult model.
dhis2w_browser.drive_login_form(auth_url, *, username, password)	Lower-level companion to drive_oauth2_login — navigates Chromium to an already-built authorize URL, fills the login form + consent screen, waits for the loopback redirect. For wiring Playwright into an in-process OAuth2Auth.redirect_capturer.
dhis2w_browser.capture_dashboard(...) / capture_visualization(...) / capture_map(...)	Render a DHIS2 dashboard / chart / map as a PNG via the respective web app. Banner + background-trim helpers available for report-friendly output.

Headless vs headful

Headless by default. Two ways to flip to visible:

1. Env var: DHIS2_HEADFUL=1 (or true/yes/on) — applies to every Playwright entry point in this package.
2. Explicit kwarg: logged_in_page(..., headless=False) — overrides env.

The d2w browser pat CLI command defaults to headful (--headful) so first-time users can watch the login; pass --headless to flip.

Why: automation wants headless for speed; humans debugging a flow want to see it. One env var covers every caller (CLI, library, tests) uniformly. See docs/decisions.md 2026-04-17.

Example

import asyncio
from dhis2w_browser import PatOptions, create_pat

async def main() -> None:
    token = await create_pat(
        "http://localhost:8080",
        "admin",
        "district",
        options=PatOptions(
            name="automation-bot",
            expires_in_days=90,
            allowed_methods=["GET", "POST"],
        ),
    )
    print(token)  # d2p_...

asyncio.run(main())

Architecture

See docs/architecture/browser.md for the longer write-up: why PAT creation has to go through a browser (DHIS2 gates /api/apiToken behind a session cookie), how logged_in_page drives the React login form, and what's on the roadmap.
