Val Town Code SearchReturn to Val Town

3## Description
4
5This is an AI-powered Grocery Shopping assistant that turns an imprecise list of items like "milk, bread, eggs" into a Kroger cart full of groceries. It relies on the Kroger API to search each item, then uses an LLM to decide which specific UPC to add to the cart (again, using the Kroger API). Once an item is selected, we store the UPC in the database so we can avoid consulting the LLM for that item again.
6
7Households have preferences for which items to buy, and what priorities they have for each item. For example, we prefer to buy free range eggs and poultry, but don't particularly care whether they are organic or not. These details are stored in a database, which should also be consulted to add context to the LLM's decisions.

9## Kroger OAuth Implementation
35- **User Management**: Create/update users based on Kroger profile ID

37## Database Schema
38
39The database consists of the following tables:
40
41### kroger_users_1
119├── backend/
120│   ├── index.ts              # Main HTTP handler with OAuth routes
121│   ├── database/
122│   │   ├── migrations.ts     # Database schema setup
123│   │   └── krogerQueries.ts  # Database query functions
124│   └── services/
125│       └── krogerAuth.ts     # Kroger OAuth service

95- **HTTP-Only Cookies**: Session cookies are not accessible via JavaScript
96- **Token Refresh**: Automatic refresh of expired access tokens
97- **Secure Storage**: Tokens are stored securely in the database

270- Handle API calls properly with proper error catching

272### Database Patterns
273- Run migrations on startup or comment out for performance
274- Change table names when modifying schemas rather than altering

9- [ ] make it one click to branch off like old jp townie demos
10- [ ] opentownie as a pr bot
11- [ ] give it the ability to see its own client-side and server-side logs by building a middleware that shoves them into a SQL light database date and then give it a tool to access them
12- [ ] do a browser use or screenshot thing to give it access to its own visual output
13- [ ] Have it default to creating a new branch off main

6// Eventually we'll have a user database,
7// but in the meantime, we can cache user info in memory
8const userIdCache: { [key: string]: any } = {};
