Documenso Local Dev Loop

Overview

Configure a fast local development environment for Documenso integrations. Covers project structure, environment configs, self-hosted Documenso via Docker, test utilities, and cleanup scripts.

Prerequisites

• Completed documenso-install-auth setup
• Node.js 18+ with TypeScript
• Docker (for self-hosted local Documenso)

Instructions

Step 1: Project Structure

my-signing-app/
├── src/
│   └── documenso/
│       ├── client.ts          # Configured SDK client
│       ├── documents.ts       # Document operations
│       ├── recipients.ts      # Recipient management
│       └── webhooks.ts        # Webhook handlers
├── scripts/
│   ├── verify-connection.ts   # Quick health check
│   ├── create-test-doc.ts     # Generate test documents
│   └── cleanup-test-docs.ts   # Remove test data
├── tests/
│   └── integration/
│       ├── document.test.ts
│       └── template.test.ts
├── .env.development
├── .env.test
└── .env.production

Step 2: Environment Configuration

.env.development:

DOCUMENSO_API_KEY=api_dev_xxxxxxxxxxxx
DOCUMENSO_BASE_URL=https://stg-app.documenso.com/api/v2
DOCUMENSO_WEBHOOK_SECRET=whsec_dev_xxxxxxxxxxxx
LOG_LEVEL=debug

.env.test:

DOCUMENSO_API_KEY=api_test_xxxxxxxxxxxx
DOCUMENSO_BASE_URL=https://stg-app.documenso.com/api/v2
DOCUMENSO_WEBHOOK_SECRET=whsec_test_xxxxxxxxxxxx
LOG_LEVEL=warn

Step 3: Client Wrapper with Dev Helpers

// src/documenso/client.ts
import { Documenso } from "@documenso/sdk-typescript";

let _client: Documenso | null = null;

export function getClient(): Documenso {
  if (!_client) {
    _client = new Documenso({
      apiKey: process.env.DOCUMENSO_API_KEY!,
      ...(process.env.DOCUMENSO_BASE_URL && {
        serverURL: process.env.DOCUMENSO_BASE_URL,
      }),
    });
  }
  return _client;
}

// Dev helper: list recent documents for debugging
export async function listRecentDocs(limit = 5) {
  const client = getClient();
  const { documents } = await client.documents.findV0({
    page: 1,
    perPage: limit,
    orderByColumn: "createdAt",
    orderByDirection: "desc",
  });
  return documents;
}

Step 4: Self-Hosted Local Documenso (Docker)

# Pull the official Documenso Docker image
docker pull documenso/documenso:latest

# Create docker-compose.local.yml

# docker-compose.local.yml
services:
  documenso:
    image: documenso/documenso:latest
    ports:
      - "3000:3000"
    environment:
      - NEXTAUTH_URL=http://localhost:3000
      - NEXTAUTH_SECRET=local-dev-secret-change-me
      - NEXT_PRIVATE_ENCRYPTION_KEY=local-encryption-key
      - NEXT_PRIVATE_ENCRYPTION_SECONDARY_KEY=local-secondary-key
      - NEXT_PUBLIC_WEBAPP_URL=http://localhost:3000
      - NEXT_PRIVATE_DATABASE_URL=postgresql://documenso:password@db:5432/documenso
      - NEXT_PRIVATE_DIRECT_DATABASE_URL=postgresql://documenso:password@db:5432/documenso
      - NEXT_PRIVATE_SMTP_TRANSPORT=smtp-auth
      - NEXT_PRIVATE_SMTP_HOST=mailhog
      - NEXT_PRIVATE_SMTP_PORT=1025
    depends_on:
      - db
      - mailhog

  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: documenso
      POSTGRES_PASSWORD: password
      POSTGRES_DB: documenso
    volumes:
      - pgdata:/var/lib/postgresql/data

  mailhog:
    image: mailhog/mailhog
    ports:
      - "8025:8025"  # Web UI for email inspection
      - "1025:1025"

volumes:
  pgdata:

docker compose -f docker-compose.local.yml up -d
# Documenso at http://localhost:3000
# MailHog at http://localhost:8025 (view sent emails)

.env.local (for self-hosted dev):

DOCUMENSO_API_KEY=api_local_xxxxxxxxxxxx
DOCUMENSO_BASE_URL=http://localhost:3000/api/v2

Step 5: Quick Verification Script

// scripts/verify-connection.ts
import { getClient } from "../src/documenso/client";

async function verify() {
  const client = getClient();
  try {
    const { documents } = await client.documents.findV0({ page: 1, perPage: 1 });
    console.log("Connection OK");
    console.log(`Documents accessible: ${documents.length >= 0 ? "yes" : "no"}`);
  } catch (err: any) {
    console.error(`Connection FAILED: ${err.message}`);
    if (err.statusCode === 401) console.error("Check DOCUMENSO_API_KEY");
    process.exit(1);
  }
}
verify();

Step 6: Test Cleanup Script

// scripts/cleanup-test-docs.ts
import { getClient } from "../src/documenso/client";

async function cleanup() {
  const client = getClient();
  const { documents } = await client.documents.findV0({ page: 1, perPage: 100 });

  const testDocs = documents.filter((d: any) =>
    d.title.startsWith("[TEST]") || d.title.startsWith("Hello World")
  );

  for (const doc of testDocs) {
    if (doc.status === "DRAFT") {
      await client.documents.deleteV0(doc.id);
      console.log(`Deleted: ${doc.title} (${doc.id})`);
    } else {
      console.log(`Skipped (${doc.status}): ${doc.title}`);
    }
  }
  console.log(`Cleaned up ${testDocs.filter((d: any) => d.status === "DRAFT").length} test docs`);
}
cleanup();

Step 7: Development Scripts (package.json)

{
  "scripts": {
    "dev:verify": "tsx scripts/verify-connection.ts",
    "dev:test-doc": "tsx scripts/create-test-doc.ts",
    "dev:cleanup": "tsx scripts/cleanup-test-docs.ts",
    "dev:local": "docker compose -f docker-compose.local.yml up -d",
    "dev:local:stop": "docker compose -f docker-compose.local.yml down",
    "test:integration": "vitest run tests/integration/"
  }
}
