Preset for graphql-codegen to parse and type queries to Shopify APIs
npm install @shopify/api-codegen-preset@shopify/api-codegen-preset

This package enables JavaScript / TypeScript apps to use a #graphql tag to parse queries with graphql-codegen.
It produces TypeScript types for every query picked up by your codegen configuration.
Shopify's clients are then able to use those types to automatically type your operation's variables and return types.
The first step is to install the @shopify/api-codegen-preset package, using your preferred package manager:
``sh`
yarn add --dev @shopify/api-codegen-preset
`sh`
npm add --save-dev @shopify/api-codegen-preset
`sh`
pnpm add -D @shopify/api-codegen-preset
This package provides 3 key exports, that make it increasingly easier to set up a project:
1. preset: provides the low-level implementation that converts the schema into types. Include this in a generates step.shopifyApiTypes
1. : provides all the generates steps needed for a project.shopifyApiProject
1. : one-stop-shop setup for an entire codegen project.
Use this as a Codegen preset inside a generates step.
This gives you complete control over your configuration if you want to set up a fully custom scenario.
| Option | Type | Default | Description |
| ------- | --------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| apiType | ApiType | _N/A_ | The API to pull schemas from. |string?
| module | | Depends on ApiType | Change the module whose types will be overridden. Use this to override the types for any package, as long as it uses the same names. |
> [!TIP]
> You can also set your codegen configuration to output .ts files, instead of .d.ts.
> That may slightly increase build sizes, but it enables you to import enums from the schema in your app code.
#### Example .graphqlrc.ts file
`ts
import {ApiType, pluckConfig, preset} from '@shopify/api-codegen-preset';
export default {
// For syntax highlighting / auto-complete when writing operations
schema: 'https://shopify.dev/admin-graphql-direct-proxy/2025-01',
documents: ['./*/.{js,ts,jsx,tsx}'],
projects: {
default: {
// For type extraction
schema: 'https://shopify.dev/admin-graphql-direct-proxy/2025-01',
documents: ['./*/.{js,ts,jsx,tsx}'],
extensions: {
codegen: {
// Enables support for #graphql tags, as well as / GraphQL /`
pluckConfig,
generates: {
'./types/admin.schema.json': {
plugins: ['introspection'],

Use this function if you want to configure a custom project, or add your own steps.
| Option | Type | Default | Description |
| ------------ | ----------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| apiType | ApiType | _N/A_ | The API to pull schemas from. |string?
| apiVersion | | Oldest stable version| Pull schemas for a specific version. |string?
| apiKey | | _N/A_ | The app's API key. This can be found in the app's page in Shopify Partners in the "Authentication" section. Required and only valid for the customer API preset and helpers for now |string?
| outputDir | | . | Where to output the types files. |string[]?
| documents | | ./*/.{ts,tsx} | Glob pattern for files to parse. |string?
| module | | Depends on ApiType | Change the module whose types will be overridden. Use this to override the types for any package, as long as it uses the same names. |boolean?
| declarations | | true | When true, create declaration (.d.ts) files with the types. When false, creates .ts files that can be imported in app code. May slightly increase build sizes. |boolean?
| enumsAsConst | | false | When true, generates enums as const assertions instead of TypeScript enums. This removes the need for runtime imports. |
#### Example .graphqlrc.ts file
`js
import {
ApiType,

shopifyApiTypes,
} from '@shopify/api-codegen-preset';
export default {
// For syntax highlighting / auto-complete when writing operations

#### Example .graphqlrc.ts file
`js
import {shopifyApiProject, ApiType} from '@shopify/api-codegen-preset';
export default {
// For syntax highlighting / auto-complete when writing operations
schema: 'https://shopify.dev/admin-graphql-direct-proxy/2025-01',
documents: ['./app/*/.{js,ts,jsx,tsx}'],
projects: {
// To produce variable / return types for Admin API operations
default: shopifyApiProject({
apiType: ApiType.Admin,
apiVersion: '2025-01',
documents: ['./app/*/.{js,ts,jsx,tsx}'],
outputDir: './app/types',
}),
},
};
`
#### Example with enumsAsConst option
`js
import {shopifyApiProject, ApiType} from '@shopify/api-codegen-preset';
export default {
schema: 'https://shopify.dev/admin-graphql-direct-proxy/2025-01',
documents: ['./app/*/.{js,ts,jsx,tsx}'],
projects: {
default: shopifyApiProject({
apiType: ApiType.Admin,
apiVersion: '2025-01',
documents: ['./app/*/.{js,ts,jsx,tsx}'],
outputDir: './app/types',
enumsAsConst: true, // Generate enums as const assertions
}),
},
};
`
With enumsAsConst: true, you can use enum values directly without imports:
`typescript
// Without enumsAsConst (default)
import { MetafieldOwnerType } from './app/types/admin.types';
const variables = { ownerType: MetafieldOwnerType.Product };
// With enumsAsConst: true
const variables = { ownerType: 'PRODUCT' }; // No import needed!
`
#### Example .graphqlrc.ts file with to generate types for UI extensions.graphqlrc.ts
You can specify multiple APIs in your file by adding multiple projects. See Generating types for multiple APIs for more information.
`js
import { ApiVersion } from "@shopify/shopify-api";
import { shopifyApiProject, ApiType } from "@shopify/api-codegen-preset";
import type { IGraphQLConfig } from "graphql-config";
function getConfig() {
const config: IGraphQLConfig = {
projects: {
default: shopifyApiProject({
apiType: ApiType.Admin,
apiVersion: ApiVersion.July25,
documents: ["./app//.{js,ts,jsx,tsx}", "./app/.server//.{js,ts,jsx,tsx}" ],
outputDir: "./app/types",
}),
UIExtensions: shopifyApiProject({
apiType: ApiType.Storefront,
apiVersion: ApiVersion.July25,
documents: ["./extensions//.{js,ts,jsx,tsx}", "./extensions/.server//.{js,ts,jsx,tsx}"],
outputDir: "./extensions/types",
}),
},
};
const config = getConfig();
export default config;
`
ts
import fs from "fs";
import { ApiVersion } from "@shopify/shopify-api";
import { shopifyApiProject, ApiType } from "@shopify/api-codegen-preset";
import type { IGraphQLConfig } from "graphql-config";function getConfig() {
const config: IGraphQLConfig = {
projects: {
// Generate types for your app
default: shopifyApiProject({
apiType: ApiType.Admin,
apiVersion: ApiVersion.July25,
documents: ["./app//.{js,ts,jsx,tsx}", "./app/.server//.{js,ts,jsx,tsx}"],
outputDir: "./app/types",
}),
},
};
// Enables autocompletion for your Shopify Functions
let extensions: string[] = [];
try {
extensions = fs.readdirSync("./extensions");
} catch {
// ignore if no extensions
}
for (const entry of extensions) {
const extensionPath =
./extensions/${entry};
const schema = ${extensionPath}/schema.graphql;
if (!fs.existsSync(schema)) {
continue;
}
config.projects[entry] = {
schema,
documents: [${extensionPath}/*/.graphql],
};
} return config;
}
const config = getConfig();
export default config;
`Generating types
Once you configure your app, you can run
graphql-codegen to start parsing your queries for types.To do that, add this
script to your package.json file:`json
{
"scripts": {
// ...
"graphql-codegen": "graphql-codegen"
}
}
`You can then run the script using your package manager:
`sh
yarn graphql-codegen
``sh
npm run graphql-codegen
``sh
pnpm graphql-codegen
`$3
If you have specified more than one API in your
.graphqlrc.ts file, you can run the script for each API by passing the --project flag.`sh
npm run graphql-codegen --project=UIExtensions
``sh
yarn graphql-codegen --project=UIExtensions
``sh
pnpm graphql-codegen --project=UIExtensions
`> [!NOTE]
> Codegen will fail if it can't find any documents to parse.
> To fix that, either create a query or set the
ignoreNoDocuments option to true.
> Queries and mutations must have a name for the parsing to work.Once the script parses your operations, you can mark any operations for parsing by adding the
#graphql tag to the string.
For example:`ts
import '../types/admin.generated.d.ts';const response = await myGraphqlClient.graphql(
#graphql,
{
variables: {
first: 1,
} as GetProductsQueryVariables,
},
);const data: GetProductsQuery = response.data;
`You'll note that once the script parses this query, the
admin.generated.d.ts file will start including a new GetProductsQuery type that maps to your query.You can commit these types to your repository, so that you don't have to re-run the parsing script every time.
To make your development flow faster, you can pass in the
--watch flag to update the query types whenever you save a file:`sh
npm run graphql-codegen -- --watch
`$3
With Shopify App Bridge, you can use Direct API Access to make API requests from your apps frontend directly to the Admin API.
Because you are using the Fetch API directly, the responses cannot be automatically typed. Here is how to manually type them using the automatically generated types:
`js
import type { GetProductsQuery } from "app/types/admin.generated";const fetchProduct = async () => {
const res = await fetch('shopify:admin/api/graphql.json', {
method: 'POST',
body: JSON.stringify({
query:
#graphql as const,
variables: { first: 1 },
}),
}); const { data } = (await res.json()) as { data: GetProductsQuery };
console.log(data.products.edges[0]?.node);
};
