From 1644110ceeba0eaaf6e919f89f3bd90979093fc4 Mon Sep 17 00:00:00 2001 From: DSS Date: Wed, 10 Dec 2025 14:02:01 -0300 Subject: [PATCH] feat(storybook): Add Web Component support to story generator MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Storybook generator now supports Web Components in addition to React: - Added ComponentType enum (REACT, WEB_COMPONENT) - Enhanced _parse_component to detect Web Components via HTMLElement/customElements - Added _parse_web_component to extract attributes from JSDoc and observedAttributes - Added _generate_csf3_web_component for Web Component story generation - Updated file patterns to include .js files - Moved ds-button.js to src/components/ for proper discovery - Fixed missing requests import in figma.py The generator now successfully generates Storybook stories for admin-ui's ds-button Web Component with all variants, sizes, and states. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- admin-ui/ds.config.json | 2 +- admin-ui/{js => src}/components/ds-button.js | 0 dss/project/figma.py | 1 + dss/storybook/generator.py | 447 +++++++++++++++++-- 4 files changed, 421 insertions(+), 29 deletions(-) rename admin-ui/{js => src}/components/ds-button.js (100%) diff --git a/admin-ui/ds.config.json b/admin-ui/ds.config.json index 915703c..b6407b4 100644 --- a/admin-ui/ds.config.json +++ b/admin-ui/ds.config.json @@ -24,5 +24,5 @@ ] }, "created_at": "2025-12-10T12:52:18.513773", - "updated_at": "2025-12-10T13:01:40.642236" + "updated_at": "2025-12-10T13:46:05.807775" } \ No newline at end of file diff --git a/admin-ui/js/components/ds-button.js b/admin-ui/src/components/ds-button.js similarity index 100% rename from admin-ui/js/components/ds-button.js rename to admin-ui/src/components/ds-button.js diff --git a/dss/project/figma.py b/dss/project/figma.py index 76dbb61..9201269 100644 --- a/dss/project/figma.py +++ b/dss/project/figma.py @@ -9,6 +9,7 @@ import os import json import asyncio import time +import requests from datetime import datetime from pathlib import Path from typing import Any, Dict, List, Optional, Tuple diff --git a/dss/storybook/generator.py b/dss/storybook/generator.py index 1cd6452..7136eeb 100644 --- a/dss/storybook/generator.py +++ b/dss/storybook/generator.py @@ -7,14 +7,21 @@ variants, and integration points.
