bilig
Run workbook-shaped business rules inside Node.
Bilig gives services, queue workers, tests, MCP servers, and tool integrations a typed WorkPaper object: write inputs, recalculate formulas, read outputs, persist JSON, restore, and verify. It fits pricing models, quote approval, payout checks, import validation, forecasts, and formula-backed workflow steps.
Run the no-project service check from any Node project:
npm exec --yes --package @bilig/workpaper@latest -- bilig-evaluate --door workpaper-service --jsonExpected WorkPaper service result:
{
"schemaVersion": "bilig-evaluator.v1",
"door": "workpaper-service",
"verified": true,
"evidence": {
"editedCell": "Inputs!B2",
"dependentCell": "Summary!B2",
"before": 24000,
"after": 38400,
"afterRestore": 38400,
"persistedDocumentBytes": 999
}
}For TypeScript services that should own the workbook model:
npm create @bilig/workpaper@latest pricing-workpaper
cd pricing-workpaper
npm install
npm run smoke
