I have personally put a ts-ignore for ignore errors.

// @ts-ignore
import GraphQLUpload from 'graphql-upload/GraphQLUpload.js';
// @ts-ignore
import Upload from 'graphql-upload/Upload.js';

And imports like that. I hope it can help even if it's dirty!

graphql-upload library doesn't have any main index.js re-export for all of its functions. It has direct file exports for all the specific functionalities. It is specified in its package.json file under exports key like so:

"exports": {
    "./GraphQLUpload.js": "./GraphQLUpload.js",
    "./graphqlUploadExpress.js": "./graphqlUploadExpress.js",
    "./graphqlUploadKoa.js": "./graphqlUploadKoa.js",
    "./package.json": "./package.json",
    "./processRequest.js": "./processRequest.js",
    "./Upload.js": "./Upload.js"
  },

So instead of directly importing from package root you need to specify a sub-module path like this:

import graphqlUploadKoa from "graphql-upload/graphqlUploadKoa.js";

Reference: package.json of graphql-upload

So the problem was in the .default build settings. You can remove it, but when we removed it we saw the problem with other modules, so we resolved this issue via this:

import Upload = require('graphql-upload/Upload.js');

It looks very dirty, but it works.

You can check conversation about this module in issues on GitHub: https://github.com/jaydenseric/graphql-upload/issues/305#issuecomment-1136574019

The owner of the package just chooses to restrict importing everything from the index file, so to run the new version (> 13.0.0) you have to change the way you are importing the package:

const graphqlUploadExpress = require('graphql-upload/graphqlUploadExpress.js');

or

const GraphQLUpload = require('graphql-upload/GraphQLUpload.js');

Alternatively, you can download grade your package to version 13.0.0

Just like every answer, the maintainer of the package has chosen to restrict the imports for this package. I run into the same issue and have decided to stick with version 13 moving forward.

You can use the old imports with version 13

import { graphqlUploadExpress } from 'graphql-upload';

Just ran into this problem. Apparently, the the new version i.e. ^16 ,has a major update

now you need to do

const Upload = require('graphql-upload/Upload.mjs');

or

import { default as Upload } from 'graphql-upload/Upload.mjs';

Instead of .js, all the imports needs to be from .mjs.

Hope this helps!

use version v15.0.1 for graphql-upload

import like this:

import GraphQLUpload from 'graphql-upload/GraphQLUpload.js';

import graphqlUploadExpress from 'graphql-upload/graphqlUploadExpress.js';

https://github.com/jaydenseric/graphql-upload/issues/314#issuecomment-1140441744

https://github.com/jaydenseric/graphql-upload/releases/tag/v15.0.1

Supported runtime environments:

Node.js versions ^14.17.0 || ^16.0.0 || >= 18.0.0.

  • Projects must configure TypeScript to use types from the ECMAScript modules that have a // @ts-check comment:

  • compilerOptions.allowJs should be true.

  • compilerOptions.maxNodeModuleJsDepth should be reasonably large, e.g. 10.

  • compilerOptions.module should be "node16" or "nodenext".
