[ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './ed25519' is not defined by "exports"

[HernanPaez]

Hi! I am trying to replace the old web3storage library with the new one but I am having problems when I try to run my server

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './ed25519' is not defined by "exports" in /Users//server-proyect/node_modules/@ucanto/principal/package.json

I don't know how to fix this issue. This is a new typescript project

Here is my code:

import { Signer } from '@ucanto/principal/ed25519'
import { importDAG } from "@ucanto/core/delegation";
import { CarReader } from "@ipld/car";
import { create, Client } from "@web3-storage/w3up-client";

class Web3StorageClient {
  client?: Client;

  async init() {
    if (process.env.W3_KEY && process.env.W3_PROOF) {
      const principal = Signer.parse(process.env.W3_KEY);
      const client = await create({ principal });

      // now give Agent the delegation from the Space
      const proof = await this.parseProof(process.env.W3_PROOF);
      const space = await client.addSpace(proof);
      await client.setCurrentSpace(space.did());
    } else {
      throw "check W3_KEY and W3_PROOF environment variables";
    }
  }

  /** @param {string} data Base64 encoded CAR file */
  async parseProof(data: string) {
    const blocks: any = [];
    const reader = await CarReader.fromBytes(Buffer.from(data, "base64"));
    for await (const block of reader.blocks()) {
      blocks.push(block);
    }
    return importDAG(blocks);
  }

  async storeFile(id: string, bufferPdf: any, extension = "pdf") {
    if (!this.client) {
      throw "Client has not been initialized";
    }

    const file = new File([bufferPdf], `${id}.${extension}`);
    const cid = await this.client.uploadFile(file);
    return cid.toString();
  }

  async createNftMetadata(nftRequestJson: File[]) {
    const res = await this.client?.uploadDirectory(nftRequestJson);
    return res?.toString();
  }
}

export default Web3StorageClient;

This is also happening to me. In fact, attempting to import any of the 4 necessary dependencies causes errors; '@ucanto/principal/ed25519', '@ucanto/core/delegation', '@ipld/car', '@web3-storage/w3up-client' all cannot be imported/accessed.

I am attempting to import and access these dependencies in a Docker image with Typescript.

When I try to isolate "the" issue to a single dependency by only importing/accessing one dependency at a time, I get the following errors;

I'm experiencing the same problem. To provide additional context, my code is executed within a Docker environment, and I'm using Node.js version 16.20.2.

[heyjay44]

@HernanPaez which version of node are you using? The client requires version 18 or higher.

@thanapat-civicledger let us know if the issue persists after upgrading node.

[heyjay44]

@magror which version of node are you using?

[magror]

@magror which version of node are you using?

@heyjay44 Im using Node 18

My Dockerfile uses Node 18, too: FROM public.ecr.aws/lambda/nodejs:18

[vasco-santos]

Hey folks @HernanPaez @magror

Looks like this is a result of typescript project being compiled to CJS, which is not supported anymore by web3.storage. Like most of JS ecosystem we are moving towards ESM only module publishing.

I created a local typescript project where I made package.json to have a "type": "module", + on your tsconfig.json I updated the module to NodeNext. Can you try it out?

[magror]

@vasco-santos What is "CSM"? I cannot find any information about that acronym. Did you mean "CJS"?

[vasco-santos]

Bahm, yes CJS 🤦🏼‍♂️

[magror]

@vasco-santos adding type: module to package.json and setting module: NodeNext in tsconfig.json has allowed me to import/access this dependency. Thank you
