Getting Started

Prerequisites

Before you can use this library, you must complete the following steps:

1. Create a Gelato Account
2. Generate an API Key

Installation

# npm
npm install gelato-admin

# yarn
yarn add gelato-admin

Usage

Every API service is tied to a GelatoClient instance, whose sole purpose is to handle the request/response life-cycle when querying and mutating your Gelato data.

There are two ways to initialize a GelatoClient:

1. Using an environment variable (recommended)

See .env.example.

# .env

GELATO_API_KEY=my-api-key

import { initializeClient } from 'gelato-admin';

// Auto-detect API key from `.env` file
const client = initializeClient();

// The above snippet is a short-hand equivalent for:
const client = initializeClient({ apiKey: process.env.GELATO_API_KEY });

2. Setting API key explicitly

Useful for on-demand client initialization. Required for named clients.

import { initializeClient } from 'gelato-admin';

const client = initializeClient({ apiKey: 'my-api-key' });

Using named clients

Note: The usage of named clients is not a native Gelato API feature. It is a design decision based on the idea that you may have different Gelato accounts you want to use within the same application context.

You may initialize as many client instances as you like, provided you initialize them with a unique name. If you only have a single Gelato account, however, there is no need to use named clients at all.

To initialize a named client, pass an unique name as the second argument.

import { initializeClient } from 'gelato-admin';

// Auto-detect API key from `.env` file, but use a specific name for the client instance.
const myDefaultNamedClient = initializeClient({}, 'my-named-client');

// Use another Gelato account API key
const myOtherClient = initializeClient({ apiKey: 'other-account-api-key' }, 'other-account-client');

Accessing client instances

import { getClient } from 'gelato-admin';

// Get the default client
const defaultClient = getClient();

// Get a named client
const myNamedClient = getClient('my-named-client');

Using API services

Here is an overview of Gelato API services available in this library.

Default client

import { getProductsAPI } from 'gelato-admin/products';

// Get the products API service from the default client.
const productsAPI = getProductsAPI();

// Get a list of all catalogs
const catalogs = await productsAPI.getCatalogs();

Named client

To target a named client, pass the client instance as the first argument to the desired API service function:

import { initializeClient } from 'gelato-admin';
import { getOrdersAPI } from 'gelato-admin/orders';

// Initialize a named client with the API key from the environment variable
const mySpecialClient = initializeClient({ apiKey: 'my-other-api-key' }, 'my-special-client');

// Get the products API service using the named client.
const ordersAPI = getOrdersAPI(mySpecialClient);

// Get a list of all orders
const orders = await ordersAPI.getOrders();

Running tests

Unit tests

yarn run test

E2E tests

yarn run test:e2e

E2E tests only create draft orders. In case E2E tests fail, make sure to check your Gelato dashboard for whether any orders other than draft orders were created. If so, you must delete them manually.
