Example: Inventory Tracker

An inventory management app demonstrating number and boolean fields, category filtering, and bulkUpdateRecords for stocktake adjustments.

Schema

Entity: Items — key: items

Field	Type	Notes
`name`	text
`sku`	text
`category`	enum	electronics / furniture / supplies / other — indexed
`quantity`	number	min: 0
`unit_price`	currency	min: 0
`location`	text
`is_low_stock`	boolean
`last_restocked`	date
`notes`	multiline

Key Patterns

Boolean Filter

// Low stock only
filter.is_low_stock = { eq: true };

// In stock only
filter.is_low_stock = { eq: false };

Number Field Handling

Always convert form input strings to numbers before sending to the SDK — form inputs return strings even for type="number":

quantity: document.getElementById('quantity').value !== ''
  ? Number(document.getElementById('quantity').value)
  : null,

Bulk Stocktake Adjustment

Update multiple items at once after a stocktake. The update is all-or-nothing: if any item fails validation, nothing is changed and the call throws.

const adjustments = [
  { id: '01JA...', data: { quantity: 45, is_low_stock: false } },
  { id: '01JB...', data: { quantity: 3,  is_low_stock: true  } },
  { id: '01JC...', data: { quantity: 0,  is_low_stock: true  } },
];

try {
  await sdk.bulkUpdateRecords('items', adjustments);
} catch (error) {
  if (error instanceof HaspSDK.HaspSDKError && error.code === HaspSDK.ErrorCode.ValidationFailed) {
    // No quantities were changed. Keys look like 'updates.1.data.quantity'.
    console.warn('Stocktake rejected:', error.getFieldErrors());
  } else {
    throw error;
  }
}

Low-Stock Indicator

const qtyClass = item.is_low_stock ? 'low' : 'ok';
// render: <span class="qty low">3 <span class="low-badge">LOW</span></span>
