@suaveplan/api-plugin-export - Data-export plugin for @suaveplan/api: CSV (RFC 4180), JSON, and XLSX (SpreadsheetML XML) exporters, in-memory job store, OpenAPIHono route group at /exports, ExportError hierarchy, OTel instruments.

Data-export plugin for @suaveplan/api. Turns any registered resource into a CSV (RFC 4180), JSON, or XLSX (SpreadsheetML XML) blob through three self-contained exporter classes, a DataProvider registry, an in-memory job-lifecycle store, and an OpenAPIHono route group at the configured basePath (default /exports).

Quick start

import { createPluginRegistry } from "@suaveplan/api-plugin";
import {
    createExportPlugin,
    type DataProvider,
} from "@suaveplan/api-plugin-export";

const registry = createPluginRegistry();
registry.register(createExportPlugin({ basePath: "/v1/exports" }));
await registry.init();
await registry.ready();

const providers = registry.getService("exportProviders");
if (providers) {
    const userProvider: DataProvider = {
        resource: "users",
        fetch: async () => db.select("user").get(),
    };
    providers.set(userProvider.resource, userProvider);
}

POST /v1/exports/  → { format: "csv", resource: "users" }
GET  /v1/exports/  → { items: ExportJob[], total }
GET  /v1/exports/{id}  → ExportJob
DELETE /v1/exports/{id}  → { success: true }

Scope notes

This package ships the upstream §2 functional surface (CSV / JSON / SpreadsheetML XML exporters + in-memory job store + four-route Hono group). The upstream §3–§4 enhancements (streaming exporters, S3-backed blob store, auth/permissions/rate-limit/idempotency middleware, OOXML/ZIP writer, scheduled exports, signed download URLs, Parquet/Markdown formats) are deferred to follow-up changes — they require downstream plugins that have not yet landed .
