Can't import enum from generated GraphQL type definition files

[vincaslt]

The GraphQL type definitions are generated into admin.types.d.ts file as per: https://github.com/Shopify/shopify-api-js/blob/3e55838fe4f192d5d639670834f2a002800ba271/packages/api-codegen-preset/src/helpers/api-configs.ts#L24

The problem I'm facing is that I can't import enum from the generated file - .d.ts files are discarded during compilation.

So this import won't work:

import { ImageContentType } from "~/types/admin.types";

[ERROR] Could not resolve "~/types/admin.types":

Am I maybe wrong to try to import stuff from those files and they should be used somehow differently?

[vincaslt]

For the time being this is a workaround (in .graphqlrc.ts):

  const defaultCfg = shopifyApiProject({
    apiType: ApiType.Admin,
    apiVersion: LATEST_API_VERSION,
    documents: ["./app/**/*.{js,ts,jsx,tsx}"],
    outputDir: "./app/types",
  });

  // Change the output file of extension for enum exports to work
  defaultCfg.extensions.codegen.generates[`${outputDir}/admin.types.ts`] =
    defaultCfg.extensions.codegen.generates[`${outputDir}/admin.types.d.ts`];
  delete defaultCfg.extensions.codegen.generates[
    `${outputDir}/admin.types.d.ts`
  ];

  const config = {
    default: defaultCfg,
    // ...
  }

Hi @vincaslt, would it work if you used import type { ImageContentType } from "~/types/admin.types"; instead of import?

I've just hit this too. Unfortunately you can't use enums from a .d.ts file. A couple of examples where I'm doing that:

const metafieldTypes = Object.values(MetafieldOwnerType)

		const response = await client.request(metafieldDefinitionsQuery, {
			variables: {
				first: 10,
				after,
				ownerType: type,
				sortKey: MetafieldDefinitionSortKeys.PinnedPosition,
				reverse: true,
			},
		})

The import type doesn't work either. Still getting the same error message

No, I have tried it, enum is not used as a type here, so it's double issue.

[matteodepalo]

Ok thank you for trying that, we've put this issue in our backlog and we'll work on it.

@vincaslt This should be solved in @shopify/api-codegen-preset. But while it's not solved, you can fix it on project level.
Modify .graphqlrc.ts file with the following code. And you will get union types instead of enums. (at least this works for me).

  for (const key in defaultProject.extensions.codegen.generates) {
    if (Object.prototype.hasOwnProperty.call(defaultProject.extensions.codegen.generates, key)) {
      const element = defaultProject.extensions.codegen.generates[key] as unknown as CodegenConfig;
      if (!element) continue;
      if (element.config) element.config.enumsAsTypes = true;
      else element.config = { enumsAsTypes: true }
    }
  }

Full config here

import fs from "fs";

import { LATEST_API_VERSION } from "@shopify/shopify-api";
import { shopifyApiProject, ApiType } from "@shopify/api-codegen-preset";
import type { IGraphQLConfig } from "graphql-config";
import type { CodegenConfig } from '@graphql-codegen/cli';

function getConfig() {
  const defaultProject = shopifyApiProject({
    apiType: ApiType.Admin,
    apiVersion: LATEST_API_VERSION,
    documents: ["./app/**/*.{js,ts,jsx,tsx}"],
    outputDir: "./app/types",
  });

  // customize graphql-codegen configuration
  for (const key in defaultProject.extensions.codegen.generates) {
    if (Object.prototype.hasOwnProperty.call(defaultProject.extensions.codegen.generates, key)) {
      const element = defaultProject.extensions.codegen.generates[key] as unknown as CodegenConfig;
      if (!element) continue;
      if (element.config) element.config.enumsAsTypes = true;
      else element.config = { enumsAsTypes: true }
    }
  }

  const config: IGraphQLConfig = {
    projects: {
      default: defaultProject,
    },
  };

  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;
}

module.exports = getConfig();

In case you want to use enums - you can modify configuration in a way to generate .ts files instead of .d.ts. See graphql-codegen typescript docs for more details.

Hi! Thank you for the proposed solution, I want to use enums to be compiled into values for run-time usage. I entered the docs documentation that you added but I don't understand exactly how or where to create the config file, do you have info? Do I need to install another package?

We're labeling this issue as stale because there hasn't been any activity on it for 60 days. While the issue will stay open and we hope to resolve it, this helps us prioritize community requests.

You can add a comment to remove the label if it's still relevant, and we can re-evaluate it.

Just want to give @kusyka911 a shoutout here - thanks! 🙏🏻

Hey folks, we've recently made some improvements to the @shopify/graphql-codegen package, which now allows configuring .ts outputs. Apps should be able to pull enums from those files directly and use them in your code normally.

To use that, you can:

• If you're using the preset directly: change your output from *.d.ts to .ts in your codegen config
• If you're using shopifyApiTypes or shopifyApiProject: pass in the declarations: false setting

Please see the README for more details. This will be available in the next release, but for extra context this is the PR that made the change: #939.

I'm going to close this issue since I believe the original issue is resolved, but please let us know if you still get errors with the next version!
