templates/bet/handlers/index.ts (2)

1-6: LGTM! Consider using named exports for better refactoring support.

The 'use server' directive and imports are correctly implemented. The imports cover various aspects of the betting process, aligning well with the PR objectives.

Consider using named exports instead of default exports in the imported files. This can make future refactoring easier and provide better autocompletion support in IDEs.

---

1-18: Overall, good implementation of a central handler access point.

This file successfully centralizes access to various betting-related handlers, aligning well with the PR objectives of implementing a p2p betting system. The structure allows for easy management and extension of betting functionality, which is crucial for the FrameTrain platform.

To further improve the architecture:

1. Consider adding JSDoc comments to describe the purpose of each handler.
2. If the handlers grow in number, consider grouping them into categories (e.g., betHandlers, arbitrationHandlers, etc.).
3. Implement error handling at this central point to ensure consistent error responses across all handlers.

templates/bet/handlers/page.ts (3)

6-13: Function signature looks good, but consider improving type safety.

The function signature is well-structured for a page handler. However, to improve type safety and reduce potential errors, consider the following suggestion:

 export default async function page({
     config,
+    body,
+    storage,
+    params,
 }: {
     body: FramePayloadValidated
     config: Config
     storage: Storage
     params: any
 }): Promise<BuildFrameData> {

This change ensures that all parameters are explicitly declared, even if not used in the current implementation. It can help prevent future errors if these parameters are needed later.

---

14-24: Implementation looks good, but consider adding more context-specific buttons.

The function implementation correctly returns a BuildFrameData object and aligns with the PR objectives. However, to enhance the betting template functionality, consider the following suggestions:

1. Add more context-specific buttons based on the betting flow. For example:

 buttons: [
     {
         label: '←',
     },
+    {
+        label: 'Place Bet',
+    },
+    {
+        label: 'View Details',
+    },
 ],

2. Consider making the aspect ratio configurable based on the content:

-aspectRatio: '1:1',
+aspectRatio: config.aspectRatio || '1:1',

3. Add error handling for the PageView component creation:

-component: PageView(config),
+component: PageView(config) || fallbackErrorView(),

These changes would make the betting template more flexible and robust, aligning better with the comprehensive betting experience outlined in the PR objectives.

---

1-24: Good start, but several key features are missing.

The current implementation provides a solid foundation for the betting template. However, to fully meet the objectives outlined in the PR summary and linked issue #158, consider implementing the following features in subsequent commits:

1. Add support for private and public bets.
2. Implement multiple currency support.
3. Include arbitrator and backup arbitrator functionality.
4. Add a "Share" button for sharing the bet via a deep link.
5. Implement different views based on user roles (creator, counterparty, or arbitrator).
6. Include sections for general settings and customization options in the inspector component.

To accommodate these features, you might need to:

• Expand the Config type to include bet visibility, currency options, and arbitrator information.
• Create additional handler functions for different stages of the betting process.
• Implement state management to track the current user's role and bet status.

Would you like assistance in planning the implementation of these features?

templates/bet/views/page.tsx (1)

1-3: LGTM! Consider destructuring the import.

The imports and 'use client' directive are correctly implemented. For better readability and to potentially reduce bundle size, consider destructuring the template import if you're only using specific properties.

You could update the import like this:

-import template from '..'
+import { initialConfig } from '..'

Then update the usage accordingly in the component.

templates/bet/views/counterpartyAccepted.tsx (1)

5-19: LGTM: Component logic is clear and concise.

The component logic is well-structured and easy to understand. Using constants for text content enhances maintainability. The BasicView component is correctly utilized with all necessary props.

Consider adding a blank line between the constant declarations and the return statement to improve readability:

 const bottomMessage = `Waiting for the deadline or arbitrator's decision`

+
 return (
     <BasicView
         title={title}

templates/bet/views/arbitratorDecided.tsx (2)

4-4: Consider destructuring function parameters for improved readability.

While the current implementation is functional, destructuring the config and storage objects in the function parameters can enhance code readability and make it clear which properties are being used.

Here's a suggested refactor:

-export default function ArbitratorDecidedView(config: Config, storage: Storage) {
+export default function ArbitratorDecidedView({
+  amount,
+  currency,
+  background,
+  primaryColor,
+  secondaryColor,
+  fontFamily
+}: Config, { winner }: Storage) {

This change would require updating the references to these properties within the function body.

---

5-9: Enhance robustness of winner determination in subtitle.

The current implementation assumes that storage.winner can only be 'user' or something else. It would be more robust to handle potential edge cases explicitly.

Consider refactoring the subtitle construction as follows:

const getWinnerText = (winner: string) => {
  switch(winner) {
    case 'user':
      return 'Creator';
    case 'counterparty':
      return 'Counterparty';
    default:
      return 'Unknown';
  }
};

const subtitle = `${config.amount} ${config.currency} - Winner: ${getWinnerText(storage.winner)}`;

This approach provides more explicit handling of the winner value and allows for easier extension if more winner types are added in the future.

templates/bet/handlers/initial.ts (3)

7-14: LGTM: Function signature is well-defined with proper typing.

The async function signature with typed parameters enhances code reliability and readability.

Consider using type aliasing for the function parameters to improve readability:

type InitialParams = {
    config: Config
    storage: Storage
}

export default async function initial({ config, storage }: InitialParams): Promise<BuildFrameData> {
    // ...
}

---

14-14: LGTM: Font loading is implemented correctly with a fallback.

The font loading logic is well-implemented, using optional chaining and providing a default font.

Consider extracting the default font name to a constant for better maintainability:

const DEFAULT_FONT = 'Roboto';
const fonts = await loadGoogleFontAllVariants(config.fontFamily ?? DEFAULT_FONT);

---

16-29: LGTM: Return statement is well-structured and aligns with requirements.

The returned object includes all necessary components for the betting interface, including buttons, fonts, and the main component.

For consistency, consider using object shorthand notation for the fonts property:

return {
    buttons: [
        { label: 'Bet' },
        {
            label: 'Create Your Own',
            action: 'link',
            target: 'https://frametra.in',
        },
    ],
    fonts,
    component: CoverView(config, storage),
    handler: 'bet',
};

templates/bet/views/cover.tsx (3)

5-10: LGTM: Function declaration and title/subtitle logic are well-implemented.

The conditional title logic correctly differentiates between public and private bets, aligning with the PR objectives. The subtitle includes key bet information as required.

Consider adding type checking or default values for the properties accessed from config and storage to improve robustness. For example:

const title = config.isPublic
    ? `Bet: ${config.betIdea ?? 'Unnamed Bet'}`
    : `This is a bet between @${config.counterparty ?? 'Unknown'} and the creator!`
const subtitle = `${config.amount ?? 0} ${config.currency ?? 'Unknown'} - Arbitrated by @${config.arbitrator ?? 'Unknown'}`

---

11-21: LGTM: BasicView component is well-utilized for the betting interface.

The BasicView component is correctly implemented with all necessary props to display the bet information and styling. The conditional bottomMessage provides appropriate feedback on the bet status.

To improve robustness, consider adding null checks or default values for the config properties used in the BasicView props. For example:

<BasicView
    // ... other props
    background={config.background ?? 'defaultBackground'}
    primaryColor={config.primaryColor ?? 'defaultPrimaryColor'}
    secondaryColor={config.secondaryColor ?? 'defaultSecondaryColor'}
    fontFamily={config.fontFamily ?? 'defaultFontFamily'}
/>

This ensures that the component doesn't break if these properties are undefined in the config object.

---

1-22: Great implementation of the CoverView component for the betting interface.

The CoverView component successfully implements the requirements outlined in issue #158. It handles both public and private bets, displays key bet information, and provides feedback on the bet status. The use of the BasicView component for rendering is appropriate and maintainable.

To further improve the component:

1. Consider adding prop validation using PropTypes or TypeScript interfaces to ensure all required props are passed and of the correct type.
2. Implement error boundaries to gracefully handle any rendering errors that might occur due to unexpected prop values.
3. Add unit tests to verify the component's behavior under different scenarios (public/private bets, accepted/waiting status).

Example of prop validation using TypeScript:

interface CoverViewProps {
  config: {
    isPublic: boolean;
    betIdea: string;
    counterparty: string;
    amount: number;
    currency: string;
    arbitrator: string;
    background: string;
    primaryColor: string;
    secondaryColor: string;
    fontFamily: string;
  };
  storage: {
    betAccepted: boolean;
  };
}

export default function CoverView({ config, storage }: CoverViewProps) {
  // ... rest of the component implementation
}

This will provide better type safety and catch potential errors earlier in the development process.

templates/bet/handlers/counterpartyAccepted.ts (3)

1-15: LGTM! Consider adding JSDoc for better documentation.

The import statements and function signature look good. The use of TypeScript for type safety is commendable. The function aligns well with the PR objectives for handling bet acceptance.

Consider adding a JSDoc comment above the function to describe its purpose and parameters. This would enhance code documentation and maintainability.

Example:

/**
 * Handles the acceptance of a bet by the counterparty.
 * @param {Object} params - The parameters object.
 * @param {FramePayloadValidated} params.body - Validated frame payload.
 * @param {Config} params.config - Configuration object.
 * @param {Storage} params.storage - Storage object.
 * @returns {Promise<BuildFrameData>} Frame data for the response.
 */

---

22-27: LGTM! Consider allowing button customization.

The return statement correctly structures the frame data, including a navigation button, fonts, and the appropriate view component.

To enhance flexibility, consider allowing button customization through the config:

buttons: [{ label: config.backButtonLabel || 'Back to Bet' }],

This would allow users to customize the button text if needed, while still providing a default.

---

1-28: Overall, good implementation with room for minor improvements.

The counterpartyAccepted handler is well-implemented and aligns with the PR objectives for the betting functionality. The use of TypeScript for type safety is commendable, and the overall structure is clear and maintainable.

To further improve the code:

1. Consider extracting the storage update logic into a separate function for better modularity.
2. Implement proper error handling throughout the function, especially for external operations like font loading.
3. Allow for more customization options through the config object, such as button labels and error messages.

These improvements will enhance the robustness and flexibility of the betting template, making it easier to maintain and extend in the future.

templates/bet/handlers/arbitratorDecided.ts (1)

28-34: Use Constants for Button Indices and Winner Values

Defining constants for button indices and winner values enhances readability and maintainability by reducing magic numbers and string literals in your code.

Define constants at the top of your file:

const BUTTON_INDEX_USER_WINNER = 1
const BUTTON_INDEX_COUNTERPARTY_WINNER = 2

const WINNER_USER = 'user'
const WINNER_COUNTERPARTY = 'counterparty'

Update the conditional statements:

- if (body.tapped_button.index === 1) {
-     storage.winner = 'user'
- } else if (body.tapped_button.index === 2) {
-     storage.winner = 'counterparty'
+ if (body.tapped_button.index === BUTTON_INDEX_USER_WINNER) {
+     storage.winner = WINNER_USER
+ } else if (body.tapped_button.index === BUTTON_INDEX_COUNTERPARTY_WINNER) {
+     storage.winner = WINNER_COUNTERPARTY
  } else {
      throw new FrameError('Invalid button pressed')
  }

templates/bet/handlers/createPaymentTransaction.tsx (2)

35-37: Provide more specific error messages

The current error message combines two potential issues:

throw new FrameError('No winner decided or counterparty address not set')

For better clarity, specify which field is missing:

 if (!storage.winner) {
     throw new FrameError('No winner decided')
 }
 if (!storage.counterpartyAddress) {
     throw new FrameError('Counterparty address not set')
 }

This way, users can quickly identify and fix the missing information.

---

47-47: Avoid unnecessary conversion to string

parseUnits returns a bigint, and if the value field accepts bigint, you don't need to convert it to a string:

value = parseUnits(config.amount.toString(), 18)

If value must be a string, ensure consistent typing throughout your code and document why the conversion is necessary.

templates/bet/views/bet.tsx (1)

31-35: Display Currency Symbols in Subtitle

In the getSubtitle function, displaying the currency symbol can enhance user understanding. Consider mapping config.currency to its corresponding symbol.

You might adjust the subtitle line:

 let subtitle = `${config.amount} ${config.currency} - Arbitrated by @${config.arbitrator}`
+// If you have a function to get the currency symbol:
+let subtitle = `${config.amount} ${getCurrencySymbol(config.currency)} - Arbitrated by @${config.arbitrator}`

And define a helper function getCurrencySymbol if it's not already available.

templates/bet/handlers/bet.ts (1)

92-92: Provide more informative error messages

The error message 'Unauthorized action' at line 92 is generic and may not provide enough context for debugging.

Enhance the error message with additional information:

-throw new FrameError('Unauthorized action')
+throw new FrameError(`Unauthorized action for user role: ${userRole}`)
