Vibe Coding Your First OSDK App

In this video, "Vibe Coding Your First OSDK App" by Ontologize, former Palantir engineers demonstrate how to build and deploy a custom, production-grade React web application—a "Coffee Operating Picture" (COP)—using Palantir's Ontology SDK (OSDK), Developer Console, and Continue.dev (an AI coding assistant inside VS Code Workspaces) [00:00].

By leveraging the OSDK, developers gain the security and real-time state management of the Palantir Ontology backend while retaining full design freedom to build custom UI components (like an animated ingredient stock ticker) that fall outside standard Workshop widgets [01:27].

Architectural Process Map: OSDK Vibe Coding & Deployment Lifecycle

The end-to-end workflow transitions across four core phases: Ontology setup, Developer Console registration, AI-driven React generation, and Production Subdomain Hosting [03:09, 18:23].

Step-by-Step Guidance: Building and Deploying an OSDK App

1. Inspect Ontology Dependencies: Define backing object types, link relationships, and workspace scope.

2. Verify your backend Ontology objects exist (e.g., Supplier, Delivery Log, Ingredient and their linking relationships) [02:01].

3. Note the exact Object Type API names to ensure correct binding during SDK generation [06:33].

4. Register Application in Developer Console: Configure application gateway, client types, and OAuth settings.

5. Press Ctrl + J to open global search and launch Developer Console [02:55].

6. Click + New Application, name it (e.g., Coffee Operating Picture), and assign it to your project folder [03:22, 03:50].

7. Select Client-Facing Application (uses end-user OAuth permissions) [04:04].

8. Auto-fill the initial development OAuth Redirect URI and click Create Application [04:34].

9. Configure Ontology SDK & Bootstrap Environment: Bind object types and generate TypeScript v2 bindings.

10. Under Ontology SDK, click Select Ontology and choose your target Ontology (irreversible choice) [06:03].

11. Click Add Object Types and select Supplier, Delivery Log, and Ingredient [06:33]. (Link types are auto-included) [06:43].

12. Click Start Developing $\rightarrow$ Select Bootstrap in Foundry $\rightarrow$ Choose TypeScript [07:02, 07:35].

13. Click Generate First Version and inspect the generated SDK documentation [07:16, 07:50].

14. Click Create Code Repository, select the React template, and click Open in VS Code Workspaces [08:21, 09:02].

15. Authorize Workspace & Vibe Code UI via Continue.dev: Authenticate dev environment and engineer UI via AI prompts.

16. Click the yellow Configure OAuth banner $\rightarrow$ Click Register Workspace to add the workspace preview URL to approved OAuth redirects [09:38].

17. Open Continue.dev in the sidebar [10:33].

18. Submit a comprehensive design prompt specifying layout, styling, and business rules [11:04]:

• Style: Dark terminal layout, monospace typography, warm brown/copper accents [11:14].
• Header Widget: Animated scrolling stock ticker displaying ingredient names, quantities, units, and status badges (green/orange/red) [12:17].
• Delivery Table: Columns for Supplier, Ingredient, Expected/Received Date, Expected/Received Quantity, and Status [13:28].
• Business Logic: Flag orders as Short if received quantity is less than expected quantity; flag orders as Overdue if missing received dates [13:56, 16:58].

1. Accept proposed code edits and authorize runtime data access requests in the preview panel [14:25, 15:45].

2. Configure Hosting Domain, Update Configs, and Tag Release: Register custom domain, update Vite configs, and tag release.

3. In Developer Console, navigate to Website Hosting $\rightarrow$ Click Request a Website Domain (e.g., coffee-operating-picture) [18:36]. Approve the request via administrative accounts [19:16].

4. In Developer Console under OAuth & Scopes, click Autofill for me to add the new production URL to allowed redirect origins, and copy the full production URL string [19:40].

5. In your code repository, open the configuration files (search for vite) and update the production redirect URL entry with the copied domain string [20:03, 20:32].

6. Click Tags $\rightarrow$ Tag Version, enter a commit message, and trigger the release build [20:41].

7. Wait for CI/CD checks to pass, then launch the live production app URL [21:24].
