  1. Run this in your app folder. It adds the module, registers it and creates its database tables.

    yarn mercato module add @northbound-run/sync-google-sheets@0.2.0 --allow-third-party && yarn generate && yarn db:migrate

    Or with create-mercato-module:

    npx create-mercato-module install @northbound-run/sync-google-sheets@0.2.0 && yarn generate && yarn db:migrate
  2. In the admin, open Roles (/backend/roles) and give its 4 permissions to the roles that need them.

  3. Restart the app.

Readme

This is the author's README, shortened. To install, use the steps in Install.

The catalog tests those steps. Install notes in the README may be out of date. The author declares Open Mercato ^0.6.5. The catalog's test installed it on 0.9.

@northbound-run/sync-google-sheets

A standalone Open Mercato Data Sync adapter that connects Google Sheets to any entity in your Open Mercato app. Import rows on demand, run them on a schedule, or keep a sheet and your entity store in sync bidirectionally — all without touching this package's source. The adapter is entity-agnostic: it delegates writes to a pluggable EntityWriter registry, so teams can support their own entity types from their own module's di.ts without forking the package.

The adapter ships in three increments: Increment 1 (import + OAuth) is production-ready today. Increment 2 adds scheduled sync by reusing the core SyncSchedule primitive. Increment 3 completes the export and bidirectional path with per-row conflict policies — the export engine design is first-of-kind within the Data Sync framework.

Requirements

  • An Open Mercato app on @open-mercato/core 0.6.x or later (the data_sync and integrations modules must be enabled)
  • Node.js 24 or later (the package builds for the node24 target and uses native fetch and other modern Node APIs)
  • A Google Cloud project with an OAuth 2.0 Client ID (Web application type), the Google Sheets API enabled, and the Google Drive API enabled

Install

1. Add the package
yarn add @northbound-run/sync-google-sheets

The package declares @open-mercato/core / @open-mercato/shared as peer dependencies — your app provides them. This matters: the Data Sync adapter registry is process-global, so a second, nested copy of core installed under this package would leave the adapter invisible to queue workers.

2. Register the module

Add one line to src/modules.ts in your Open Mercato app:

// src/modules.ts
import { enabledModules } from './modules-base'

export default [
  ...enabledModules,
  { id: 'sync_google_sheets', from: '@northbound-run/sync-google-sheets' },
]
3. Generate and migrate

Run these commands in a fresh container or terminal (not while the dev server is running the first time):

yarn generate
yarn db:migrate

yarn generate picks up the new module's entities, routes, and navigation entries. yarn db:migrate applies the migration the module ships, which creates two metadata tables — sync_google_sheets_bindings (one row per sheet↔entity binding) and sync_google_sheets_content_hashes (the echo-prevention sidecar for bidirectional sync). OAuth tokens are not stored in a module-owned table; they live in the framework's integration credential store (see How It Works).


Google OAuth Setup

Create an OAuth 2.0 Client
  1. Open Google Cloud Console and select your project (or create one).
  2. Go to APIs & Services → Credentials → Create Credentials → OAuth 2.0 Client ID.
  3. Choose Web application.
  4. Under Authorized redirect URIs add:
   https://<your-app-origin>/api/sync_google_sheets/oauth/callback

For local development also add:

   http://localhost:3000/api/sync_google_sheets/oauth/callback
  1. Copy the Client ID and Client Secret — you will need them for the environment variables below.
Enable APIs

In APIs & Services → Library, enable:

  • Google Sheets API
  • Google Drive API (used to resolve spreadsheet metadata and list available sheets)

Environment Variables

VariableRequiredDescription
GOOGLE_SHEETS_OAUTH_CLIENT_IDYesOAuth 2.0 Client ID from Google Cloud Console
