@ifc-lite/lists

Configurable property tables and schedules from IFC data. Define a list once (entity types, columns, filter conditions, grouping) and execute it against any model through a ListDataProvider interface to get typed rows, group summaries, and CSV output. This is the engine behind entity tables and schedules in the ifc-lite viewer.

Install

npm install @ifc-lite/lists

Usage

import { executeList, listResultToCSV, LIST_PRESETS } from '@ifc-lite/lists';
import type { ListDataProvider } from '@ifc-lite/lists';

const provider: ListDataProvider = createMyProvider(myData);

// LIST_PRESETS includes ready-made schedules (for example a Wall Schedule)
const result = executeList(LIST_PRESETS[0], provider);
console.log(result.rows);

const csv = listResultToCSV(result);

Features

• ListDefinition: entity types, columns, property conditions, grouping, or an explicit express-ID scope per model
• Column sources: entity attributes, property sets, quantity sets, materials, classifications, spatial containers (storey, building, site, project), and source model
• Filtering with typed PropertyCondition operators, including Bonsai-style /regex/ name patterns (compileNameMatcher, isNamePattern)
• Grouping with per-group summaries (summariseListRows)
• discoverColumns finds available columns from the actual model data
• CSV export with formula-injection guarding (listResultToCSV)
• LIST_PRESETS with common schedules
