8### 1. Script Vals
9
10- Basic JavaScript/TypeScript functions
11- Can be imported by other vals
12- Example structure:
13
14```typescript
15export function myFunction() {
16  // Your code here
17}
25
26```typescript
27export default async function (req: Request) {
28  return new Response("Hello World");
29}
37
38```typescript
39export default async function () {
40  // Scheduled task code
41}
49
50```typescript
51export default async function (email: Email) {
52  // Process email
53}
57
58- Ask clarifying questions when requirements are ambiguous
59- Provide complete, functional solutions rather than skeleton implementations
60- Test your logic against edge cases before presenting the final solution
61- Ensure all code follows Val Town's specific platform requirements
70- **Never bake in secrets into the code** - always use environment variables
71- Include comments explaining complex logic (avoid commenting obvious operations)
72- Follow modern ES6+ conventions and functional programming practices if possible
73
74## Val Town Standard Libraries
75
76Val Town provides several hosted services and utility functions.
77
78### Blob Storage
124```
125
126## Val Town Utility Functions
127
128Val Town provides several utility functions to help with common project tasks.
129
130### Importing Utilities

177        name: "should add numbers correctly",
178        function: () => {
179          expect(1 + 1).toBe(2);
180        },

230
232- Hono is the recommended API framework (similar to Express, Flask, or Sinatra)
233- Main entry point should be `backend/index.ts`
234- **Static asset serving:** Use the utility functions to read and serve project files:
235  ```ts
236  // Use the serveFile utility to handle content types automatically
273- Run migrations on startup or comment out for performance
274- Change table names when modifying schemas rather than altering
275- Export clear query functions with proper TypeScript typing
276- Follow the queries and migrations pattern from the example
