Discover, fork, and share data science workflows. A community-powered gallery where researchers publish their workflows and others can learn from, star, and fork them — like GitHub for data science pipelines. ## The Problem A new student joins Dr. Sarah's lab. She needs to build a diabetes prediction pipeline but has no idea where to start. There's no way to discover and reuse other people's workflows in Texera today. ## The Solution Workflow Hub — a browsable, searchable gallery of community workflows. Star your favorites, fork them into your workspace, publish your own. ## What's New ### Hub List Page (Sidebar → Hub → Workflow Hub) - Full-text search by name, tag, or description - Category filters: Biomedical, NLP, CV, Finance, EDA, Education, Tabular - Sort by: Trending, Most Stars, Most Forks, Recent - Featured workflows highlighted in a 3-column grid with DAG preview - Workflows generated by custom agents show an agent badge ### Workflow Detail Page - Author avatar, name, publish date - Full description - DAG preview showing operators as connected boxes - Tags - Fork button, Star toggle, stats panel (stars, forks, views, operators) - Agent config card with "Import Agent Config" button (when applicable) ### Fork — One-Click Reuse Click Fork → new workflow created as "[Fork] Original Title" → opens in workspace with all operators pre-configured → user adds their own data and runs. Fork creates a real workflow in Texera's backend, not a localStorage copy. ### Star — Save Favorites Toggle star on any workflow. Star count updates instantly. Persists across sessions. ### Publish — Share Your Work Click "Publish Workflow" on the Hub page → select one of your saved workflows → add title, description, category, tags → operators auto-extracted from workflow content → published workflow appears in the Hub for everyone. ### 15 Seed Workflows — Never Empty The Hub ships with curated community workflows: Biomedical: Diabetes Prediction (CRISP-DM), Heart Disease, Breast Cancer, COVID-19 Clinical Trials NLP: Sentiment Analysis, News Topic Classification Finance: Credit Card Fraud, Stock Price Regression CV: MNIST Digits EDA: Movie Recommendation EDA, Air Quality Education: UCI Iris Beginner, Titanic Survival, Wine Quality Tabular: Census Income Prediction Each seed includes title, author, description, category, tags, operator list, and star/fork/view counts. ## Demo Flow 1. Sidebar → "Workflow Hub" → 15 community workflows 2. Filter "Biomedical" → see diabetes, heart disease, cancer workflows 3. Click "Diabetes Prediction (CRISP-DM)" 4. See description, DAG preview, 142 stars, 38 forks 5. Click "Fork to My Workflows" 6. "[Fork] Diabetes Prediction" opens in workspace with operators 7. Configure CSV source with your own data → Run 8. Click "Publish Workflow" → share your own workflow back to the Hub <img width="1558" height="886" alt="Screenshot 2026-05-16 at 12 15 24 PM" src="https://github.com/user-attachments/assets/012d4464-5b60-4c16-b607-d53f89fb703a"; /> <img width="1312" height="639" alt="Screenshot 2026-05-16 at 12 15 29 PM" src="https://github.com/user-attachments/assets/cdb3b817-32f4-4f96-a06d-2c8401e3fecd"; /> <img width="1366" height="894" alt="Screenshot 2026-05-16 at 12 15 39 PM" src="https://github.com/user-attachments/assets/a219bf23-0611-4345-8627-1438483da4f7"; /> <img width="634" height="537" alt="Screenshot 2026-05-16 at 12 16 08 PM" src="https://github.com/user-attachments/assets/78ede57c-3ca5-47ce-9767-130eb1cc7428"; /> ## Files Changed New files: - dashboard/component/user/workflow-hub/workflow-hub-list/ — Hub list page with search, sort, categories, cards - dashboard/component/user/workflow-hub/workflow-hub-detail/ — Detail page with DAG preview, fork, star, stats - dashboard/component/user/workflow-hub/workflow-hub-publish-dialog/ — Publish modal - dashboard/service/workflow-hub/workflow-hub.service.ts — Service with seed data, localStorage CRUD, star/fork logic Modified files (additive only): - app-routing.module.ts — 2 new routes - app-routing.constant.ts — route constants - dashboard.component.html/ts — "Workflow Hub" sidebar link ## Testing - Angular typecheck: clean - Seed data renders on first visit - Search filters by name/tag/description - Category chips filter correctly - Sort works (trending/stars/forks/recent) - Star toggle persists - Fork creates real workflow in backend - Forked workflow opens in editor with operators - Publish extracts operators from workflow content -- This is an automated message from the Apache Git Service.
