## API Reference
### Array Utilities
#### `getArrFromObj(object: Record, key?: string): Array`
Converts an object to an array with customizable ID field.
```typescript
const obj = { '1': { name: 'John' }, '2': { name: 'Jane' } };
const arr = getArrFromObj(obj); // [{ id: "1", name: "John" }, { id: "2", name: "Jane" }]
```
#### `getArrFromSnap(snapshot: FirebaseSnapshot, key?: string): Array`
Converts a Firebase snapshot to an array.
```typescript
const arr = getArrFromSnap(snapshot); // [{ id: "doc1", ...data }]
```
#### `getArrFromNestedSnap(snapshot: FirebaseSnapshot, primaryKey?: string, secondaryKey?: string): Array`
Flattens a nested Firebase snapshot into a single array. Useful for handling nested collections in Firebase.
```typescript
// Example Firebase nested data
const snapshot = {
val: () => ({
store1: {
order1: { product: 'A', quantity: 1 },
order2: { product: 'B', quantity: 2 },
},
store2: {
order3: { product: 'C', quantity: 3 },
},
}),
exists: () => true,
};
// Default keys
const result1 = getArrFromNestedSnap(snapshot);
/* Output:
[
{ id: 'order1', _id: 'store1', product: 'A', quantity: 1 },
{ id: 'order2', _id: 'store1', product: 'B', quantity: 2 },
{ id: 'order3', _id: 'store2', product: 'C', quantity: 3 }
]
*/
// Custom keys
const result2 = getArrFromNestedSnap(snapshot, 'orderId', 'storeId');
/* Output:
[
{ orderId: 'order1', storeId: 'store1', product: 'A', quantity: 1 },
{ orderId: 'order2', storeId: 'store1', product: 'B', quantity: 2 },
{ orderId: 'order3', storeId: 'store2', product: 'C', quantity: 3 }
]
*/
```
### Currency Utilities
#### `formatCurrency(amount: number, currency?: currency): string`
Formats a number as currency with proper localization.
```typescript
formatCurrency(1000); // "₹1,000.00"
formatCurrency(1000, 'USD'); // "$1,000.00"
formatCurrency(1000, 'EUR'); // "€1,000.00"
```
Supports 160+ currencies including:
- USD (US Dollar)
- EUR (Euro)
- GBP (British Pound)
- JPY (Japanese Yen)
- And many more...
### Date Utilities
#### `getFutureDays(numberOfDays?: number): Date[]`
Returns an array of future dates.
```typescript
getFutureDays(3); // Next 3 days as Date objects
```
#### `getDayName(dayIndex?: number): string`
Gets the name of a day by index (0-6).
```typescript
getDayName(1); // "Monday"
getDayName(); // Current day name
```
#### `getDatesBetween(startDate: Date, endDate: Date, includeEndDate?: boolean): Date[]`
Returns an array of dates between two dates.
```typescript
const dates = getDatesBetween(new Date('2024-01-01'), new Date('2024-01-05'));
```
## TypeScript Support
This library is written in TypeScript and includes type definitions. Types are automatically imported when using TypeScript.
```typescript
import { currency } from '@ashirbad/js-core';
const price: number = 1000;
const formattedPrice: string = formatCurrency(price, 'USD');
```
