API Reference

Complete reference for Wealthfolio addon APIs. All functions require appropriate permissions in manifest.json.

Context Overview

The AddonContext is provided to your addon's enable function:

typescript
export interface AddonContext {
  api: HostAPI;
  sidebar: SidebarAPI;
  router: RouterAPI;
  onDisable: (callback: () => void) => void;
}

Basic usage:

typescript
export default function enable(ctx: AddonContext) {
  // Access APIs
  const accounts = await ctx.api.accounts.getAll();
  #### `onDropHover(callback: EventCallback): Promise<UnlistenFn>`
  Fires when files are hovered over for import.

  ```typescript
  const unlistenHover = await ctx.api.events.import.onDropHover((event) => {
    console.log('File hover detected');
    showDropZone();
  });

onDrop(callback: EventCallback): Promise<UnlistenFn>

Fires when files are dropped for import.

typescript
const unlistenImport = await ctx.api.events.import.onDrop((event) => {
  console.log("File dropped:", event.payload);
  // Trigger import workflow
  handleFileImport(event.payload.files);
});

onDropCancelled(callback: EventCallback): Promise<UnlistenFn>

Fires when file drop is cancelled.

typescript
const unlistenCancel = await ctx.api.events.import.onDropCancelled(() => {
  console.log("File drop cancelled");
  hideDropZone();
});

Navigate programmatically within the Wealthfolio application.

Methods

navigate(route: string): Promise<void>

Navigate to a specific route in the application.

typescript
// Navigate to a specific account
await ctx.api.navigation.navigate("/accounts/account-123");

// Navigate to portfolio overview
await ctx.api.navigation.navigate("/portfolio");

// Navigate to activities page
await ctx.api.navigation.navigate("/activities");

// Navigate to settings
await ctx.api.navigation.navigate("/settings");

Info Navigation Routes: The navigation API uses the same route structure as the main application. Common routes include /accounts, /portfolio, /activities, /goals, and /settings.

Query API

Access and manipulate the shared React Query client for efficient data management.

Methods

getClient(): QueryClient

Gets the shared QueryClient instance from the main application.

typescript
const queryClient = ctx.api.query.getClient();

// Use standard React Query methods
const accounts = await queryClient.fetchQuery({
  queryKey: ["accounts"],
  queryFn: () => ctx.api.accounts.getAll(),
});

invalidateQueries(queryKey: string | string[]): void

Invalidates queries to trigger refetch.

typescript
// Invalidate specific query
ctx.api.query.invalidateQueries(["accounts"]);

// Invalidate multiple related queries
ctx.api.query.invalidateQueries(["portfolio", "holdings"]);

// Invalidate all account-related queries
ctx.api.query.invalidateQueries(["accounts"]);

refetchQueries(queryKey: string | string[]): void

Triggers immediate refetch of queries.

typescript
// Refetch portfolio data
ctx.api.query.refetchQueries(["portfolio"]);

// Refetch multiple queries
ctx.api.query.refetchQueries(["accounts", "holdings"]);

Integration with Events

Combine Query API with event listeners for reactive data updates:

typescript
export default function enable(ctx: AddonContext) {
  // Invalidate relevant queries when portfolio updates
  const unlistenPortfolio = await ctx.api.events.portfolio.onUpdateComplete(
    () => {
      ctx.api.query.invalidateQueries(["portfolio", "holdings", "performance"]);
    },
  );

  // Invalidate market data queries when sync completes
  const unlistenMarket = await ctx.api.events.market.onSyncComplete(() => {
    ctx.api.query.invalidateQueries(["quotes", "assets"]);
  });

  ctx.onDisable(() => {
    unlistenPortfolio();
    unlistenMarket();
  });
}

UI Integration APIs

Add navigation items to the main application sidebar.

addItem(item: SidebarItem): SidebarItemHandle

typescript
const sidebarItem = ctx.sidebar.addItem({
  id: "my-addon",
  label: "My Addon",
  route: "/addon/my-addon",
  icon: MyAddonIcon, // Optional React component
  order: 100, // Lower numbers appear first
});

// Remove when addon is disabled
ctx.onDisable(() => {
  sidebarItem.remove();
});

Router API

Register routes for your addon's pages.

add(route: RouteConfig): void

typescript
ctx.router.add({
  path: "/addon/my-addon",
  component: React.lazy(() => Promise.resolve({ default: MyAddonComponent })),
});

// Multiple routes
ctx.router.add({
  path: "/addon/my-addon/settings",
  component: React.lazy(() => Promise.resolve({ default: MyAddonSettings })),
});

Error Handling

API Error Types

typescript
interface APIError {
  code: string;
  message: string;
  details?: any;
}

Common error codes:

  • PERMISSION_DENIED - Insufficient permissions
  • NOT_FOUND - Resource not found
  • VALIDATION_ERROR - Invalid data provided
  • NETWORK_ERROR - Connection issues
  • RATE_LIMITED - Too many requests

Best Practices

typescript
try {
  const accounts = await ctx.api.accounts.getAll();

`search(

page: number, pageSize: number, filters: ActivitySearchFilters, searchKeyword: string, sort?: ActivitySort, ): Promise<ActivitySearchResponse>`

Search activities with pagination, filters, and a single optional sort.

  • page: Zero-based page index. Use 0 for the first page (e.g., for exports you can pass 0 with a large pageSize such as 1000).
  • pageSize: Number of rows per page.
  • filters: Accepts single strings or arrays for accountIds and activityTypes. Empty strings/arrays are ignored.
  • searchKeyword: Free-form keyword search; pass an empty string when unused.
  • sort: Optional sort object (defaults to { id: "date", desc: true }). Only one sort is supported.
typescript
const { data, meta } = await ctx.api.activities.search(
  0,
  50,
  {
    accountIds: "account-1", // single string or string[] both work
    activityTypes: ["BUY", "DIVIDEND"],
    symbol: "AAPL", // optional exact symbol filter
  },
  "", // optional search keyword
  { id: "date", desc: true },
);

console.log(meta.totalRowCount);

update(activity: ActivityUpdate): Promise<Activity>

Updates an existing activity with conflict detection.

typescript
const updated = await ctx.api.activities.update({
  ...existingActivity,
  quantity: 150,
  unitPrice: 145.75,
});

saveMany(activities: ActivityUpdate[]): Promise<Activity[]>

Efficiently creates multiple activities in a single transaction.

typescript
const activities = await ctx.api.activities.saveMany([
  { accountId: "account-123", activityType: "BUY" /* ... */ },
  { accountId: "account-123", activityType: "DIVIDEND" /* ... */ },
]);

delete(activityId: string): Promise<void>

Deletes an activity and updates portfolio calculations.

typescript
await ctx.api.activities.delete("activity-456");

import(activities: ActivityImport[]): Promise<ActivityImport[]>

Imports validated activities with duplicate detection.

typescript
const imported = await ctx.api.activities.import(checkedActivities);

checkImport(accountId: string, activities: ActivityImport[]): Promise<ActivityImport[]>

Validates activities before import with error reporting.

typescript
const validated = await ctx.api.activities.checkImport(
  "account-123",
  activities,
);

getImportMapping(accountId: string): Promise<ImportMappingData>

Get import mapping configuration for an account.

typescript
const mapping = await ctx.api.activities.getImportMapping("account-123");

saveImportMapping(mapping: ImportMappingData): Promise<ImportMappingData>

Save import mapping configuration.

typescript
const savedMapping = await ctx.api.activities.saveImportMapping(mapping);
typescript
try {
  const accounts = await ctx.api.accounts.getAll();
} catch (error) {
  if (error.code === "PERMISSION_DENIED") {
    ctx.api.logger.error("Missing account permissions");
    // Show user-friendly message
  } else if (error.code === "NETWORK_ERROR") {
    ctx.api.logger.warn("Network issue, retrying...");
    // Implement retry logic
  } else {
    ctx.api.logger.error("Unexpected error:", error);
    // General error handling
  }
}

Advanced Usage

Batch Operations

typescript
// Efficient batch processing
const activities = await Promise.all([
  ctx.api.activities.getAll("account-1"),
  ctx.api.activities.getAll("account-2"),
  ctx.api.activities.getAll("account-3"),
]);

// You can also scope results to a single account by passing its ID as a string.
// The host normalizes this for both desktop (Tauri) and web modes—no need to
// wrap the value in an array.

// Activity search accepts single values or arrays for filters.
const { data, meta } = await ctx.api.activities.search(
  0,
  50,
  {
    accountIds: "account-1", // single string or string[] both work
    activityTypes: ["BUY", "DIVIDEND"],
    symbol: "AAPL", // optional exact symbol filter
  },
  "", // optional search keyword
  { id: "date", desc: true },
);

console.log(meta.totalRowCount);

// Batch create
const newActivities = await ctx.api.activities.saveMany([
  {
    /* activity 1 */
  },
  {
    /* activity 2 */
  },
  {
    /* activity 3 */
  },
]);

Real-time Updates

typescript
export default function enable(ctx: AddonContext) {
  // Listen for multiple events
  const unsubscribers = [
    await ctx.api.events.portfolio.onUpdateComplete(() => refreshData()),
    await ctx.api.events.market.onSyncComplete(() => updatePrices()),
    await ctx.api.events.import.onDrop((event) => handleImport(event)),
  ];

  // Clean up all listeners
  ctx.onDisable(() => {
    unsubscribers.forEach((unsub) => unsub());
  });
}

Caching Strategies

typescript
// Simple in-memory cache
const cache = new Map();

async function getCachedAccounts() {
  if (cache.has("accounts")) {
    return cache.get("accounts");
  }

  const accounts = await ctx.api.accounts.getAll();
  cache.set("accounts", accounts);

  // Invalidate cache on updates
  const unlisten = await ctx.api.events.portfolio.onUpdateComplete(() => {
    cache.delete("accounts");
  });

  return accounts;
}

TypeScript Support

Full TypeScript definitions are provided for all APIs:

typescript
import type {
  AddonContext,
  Account,
  Activity,
  Holding,
  PerformanceHistory,
  PerformanceSummary,
  // ... and many more
} from "@wealthfolio/addon-sdk";

// Type-safe API usage
const accounts: Account[] = await ctx.api.accounts.getAll();
const holdings: Holding[] = await ctx.api.portfolio.getHoldings(accounts[0].id);

Performance Tips

  1. Use batch operations when possible
  2. Implement caching for expensive operations
  3. Listen to relevant events only
  4. Clean up resources in disable function
  5. Use React.memo for expensive components
  6. Debounce user inputs for search/filter
