</div>

Overview

Tento provides a simple yet powerful API for working with Shopify data, including metaobjects and metafields. It also provides a CLI tool for two-way synchronization between your local schema definition and Shopify.

Quick Start

Installation

You can install Tento with your preferred package manager:

npm install @drizzle-team/tento
yarn add @drizzle-team/tento
pnpm add @drizzle-team/tento
bun add @drizzle-team/tento

Schema

Declare your Tento metaobjects schema in schema.ts file. As of now Tento CLI only supports one schema file:

import { metaobject } from '@drizzle-team/tento';

export const designers = metaobject({
  name: 'Designer',
  type: 'designer',
  fieldDefinitions: (f) => ({
    fullName: f.singleLineTextField({
      name: 'Full Name',
      required: true,
      validations: (v) => [v.min(5), v.max(100)],
    }),
    description: f.singleLineTextField({
      name: 'Description',
      required: true,
      validations: (v) => [v.min(5), v.max(300)],
    }),
    link: f.url(({
      name: 'Link',
      validations: (v) => [v.allowedDomains(["github.com"])],
    }),
  }),
});

Tento queries client

import { tento } from '@drizzle-team/tento';
import * as schema from './schema';

// Using @shopify/shopify-api (or its wrappers)
import '@shopify/shopify-api/adapters/node';
import { shopifyApi, ApiVersion } from '@shopify/shopify-api';
const shopifyClient = shopifyApi({ ... });
const gqlClient = new shopifyApiClient.clients.Graphql({
  session: ...,
});

// Using raw fetch
import { createClient } from '@drizzle-team/tento';
const gqlClient = createClient({
  shop: 'your-shop-name',
  headers: {
    // any headers you need
    // Content-Type is added automatically unless you override it
    'X-Shopify-Access-Token': 'your-admin-api-access-token',
  },
  fetch: customFetch, // optionally provide your own fetch implementation
});

// Create Tento client from any Shopify client above
const client = tento({
  client: gqlClient,
  schema,
});

// Apply the local schema to Shopify
await client.applySchema();

// Query metaobjects
const designers = await tento.metaobjects.designers.list({
  first: 10,
});
/* 
  {
    _id: string;
    _handle: string;
    _updatedAt: Date;
    fullName: string;
    description: string;
    link: string;
  }[]
*/

Schema Migrations | Pull

Now let's pull your existing Shopify Metaobjects schema, first we need to create a tento.config.ts file:

import { defineConfig } from '@drizzle-team/tento/cli';

export default defineConfig({
  schemaPath: './src/schema.ts',
  shop: 'd91122',
  headers: {
    'X-Shopify-Access-Token': process.env['SHOPIFY_ADMIN_API_TOKEN']!,
  },
});

Now let's run Tento CLI pull command

npx tento pull
yarn tento pull
pnpm tento pull
bun tento pull

Tento CLI will consume tento.config.ts and fetch your Shopify schema to your project schema.ts file:

import { metaobject } from '@drizzle-team/tento';

export const orm = metaobject({
  name: 'ORM',
  type: 'orm',
  fieldDefinitions: (f) => ({
    name: f.singleLineTextField({
      name: 'Name',
      required: true,
      validations: (v) => [v.min(1), v.max(50)],
    }),
    git_hub_repo: f.url({
      name: 'GitHub repo',
      required: true,
      validations: (v) => [v.allowedDomains(["github.com"])],
    }),

Schema Migrations | Push

Whenever you change your locall schema - you can apply changes to your Shopify by using tento push command:

~ npx tento push

- Updated metaobject definition "ORM"
✅ All changes applied

It will consume your tento.config.ts file, traverse your schema and apply any diffs to Shopify.

Queries

Tento supports all Shopify Metaobject API methods:

.list()

tento.metaobjects.designers.list({
  query: {
    $raw: 'state:disabled AND ("sale shopper" OR VIP)',
  },
});

tento.metaobjects.designers.list({
  query: ['Bob', 'Norman'],
});

tento.metaobjects.designers.list({
  query: {
    displayName: {
      $raw: 'Bob Norman',
    },
  },
});

tento.metaobjects.designers.list({
  query: {
    displayName: 'Bob Norman',
    updatedAt: new Date('2023-01-01'),
  },
});

tento.metaobjects.designers.list({
  query: {
    updatedAt: {
      $gte: new Date('2023-01-01'),
      $lte: new Date('2024-01-01'),
    },
  },
});

tento.metaobjects.designers.list({
