Reducto plugin

Use Reducto through Corsair: one client, typed API calls, local DB sync. What you get:

20 typed API operations
12 synced entities (classifyOutputs, editFormFields, editOutputs, extractCitations, extractOutputs, extractRecords, and 6 more) for fast .search() / .list()

Setup

Install

npm install corsair @corsair-dev/reducto better-sqlite3
npm install --save-dev @types/better-sqlite3

yarn add corsair @corsair-dev/reducto better-sqlite3
yarn add --dev @types/better-sqlite3

pnpm install corsair @corsair-dev/reducto better-sqlite3
pnpm install --save-dev @types/better-sqlite3

bun add corsair @corsair-dev/reducto better-sqlite3
bun add --dev @types/better-sqlite3

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { reducto } from '@corsair-dev/reducto';

export const corsair = createCorsair({
	plugins: [
		reducto(),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

With multiTenancy: true, scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

API Key (Recommended)

Store the Reducto API key before the first call: pnpm corsair setup --plugin=reducto --tenant=acme api_key=<your-key> (leave out --tenant without multiTenancy), or pass it as key in the plugin options. With Hub, each tenant enters their own key on the connect page. See API key auth.

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'reducto',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

List jobs

const tenant = corsair.withTenant('acme');
await tenant.reducto.api.jobs.list({});

Parse a document

const tenant = corsair.withTenant('acme');
await tenant.reducto.api.parse.parse({ input: 'https://example.com/invoice.pdf' });

See the full list on the API page.

Query synced data

Search synced jobs without hitting Reducto.

const tenant = corsair.withTenant('acme');
const rows = await tenant.reducto.db.jobs.search({
	data: {},
	limit: 50,
});

Synced entities: classifyOutputs, editFormFields, editOutputs, extractCitations, extractOutputs, extractRecords, jobs, parseBlocks, parseChunks, parseOcrItems, pipelineOutputs, splitSegments. See Database for filters and operators.
