Tech Context

Technologies Used

Val Town: The primary platform for hosting and running the webmail application, providing serverless capabilities for HTTP and email triggers.
Deno: The runtime environment used by Val Town for executing TypeScript code, ensuring compatibility with modern JavaScript features.
SQLite: The database solution provided by Val Town for persistent storage of email data.
Drizzle ORM: An Object-Relational Mapping tool used for type-safe database interactions with SQLite, enhancing maintainability over raw SQL.
TypeScript: The programming language used for writing the application, ensuring type safety and better development experience.
@libsql/client: A library used with Drizzle ORM to interact with SQLite databases in a way compatible with Val Town's environment.

Val Town Environment: Scripts are deployed as vals within Val Town, with webmail.ts serving as an HTTP endpoint and reciever.ts as an email trigger.
Code Structure: Organized into webmail.ts for frontend and data fetching, reciever.ts for email processing, and shared/db/schema.ts for database schema definitions.

Serverless Limitations: Must operate within Val Town's serverless constraints, affecting how migrations and file management are handled.
SQLite Compatibility: Need to ensure database operations are compatible with Val Town's SQLite implementation, using @libsql/client for connectivity.

Val Town Standard Libraries: Utilizes sqlite from https://esm.town/v/std/sqlite for initial database access.
Drizzle ORM Packages: Includes npm:drizzle-orm, npm:drizzle-orm/libsql, and npm:@libsql/client for ORM functionality and database connectivity.
No External Secrets: Following Val Town best practices, no API keys or secrets are hardcoded; environment variables would be used if needed.

Drizzle ORM Query Builder: Used for constructing type-safe queries and inserts in both webmail.ts and reciever.ts.
Migration Management: Drizzle ORM's migration system is set up for schema management, pending user-provided migration files or alternative strategies.
