Rule: Domo App Platform Data Access (Toolkit-First)

This rule is toolkit/query-first. Use @domoinc/query for dataset reads in apps.

Canonical Query Approach

1) Use @domoinc/query for dataset queries

yarn add @domoinc/query

import Query from '@domoinc/query';

const salesByRegion = await new Query()
  .select(['region', 'Sales_Amount'])
  .groupBy('region', { Sales_Amount: 'sum' })
  .orderBy('Sales_Amount', 'descending')
  .fetch('sales');

2) Keep SQL as exception-only

If you use SQL (SqlClient), remember it does not automatically respect page filters in dashboards.

import { SqlClient } from '@domoinc/toolkit';

const sqlClient = new SqlClient();
const result = await sqlClient.get(
  'sales',
  'SELECT region, SUM(Sales_Amount) AS total FROM sales GROUP BY region'
);
const rows = result.body.rows;

Required Manifest Wiring

Every dataset still must be declared in manifest.json under datasetsMapping.

{
  "datasetsMapping": [
    { "alias": "sales", "dataSetId": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee", "fields": [] }
  ]
}

Critical gotcha:

• fields must exist (can be []) to avoid manifest parsing errors.

Local Development

• Use @domoinc/ryuu-proxy for local API routing.
• Authenticate with domo login.

Checklist

• datasetsMapping aliases configured and valid
• Queries implemented with Query (not raw /data/v1 by default)
• Aggregations use actual dataset field names
• .aggregate() not used
