Dynamic Items

While some items come in well-defined shapes, others, such as a database record or a spreadsheet row, don't have a definitive one. Or maybe it's a mix of the two, with an item that support custom fields. A connector can easily support these use cases by dynamically building the schema of its items.

const schema: FieldSchema[] = [
  {
    name: 'id',
    label: 'Unique ID',
    type: FieldValueType.STRING,
  }
];

for await (const customField of fetch(...)) {
  schema.push({
    name: customField.name,
    label: customField.label,
    type: customField.type
  })
}

return schema

Be careful to properly map the types of your dynamic fields to ones that are supported by the specification.
