Build and runtime issues on node with ESBuild

[dankelleher]

Describe the bug
ESBuild has issues building this library.

The three issues I am having:

1. (build time) ../../node_modules/ky-universal/index.js:28:30: ERROR: Top-level await is currently not supported with the "cjs" output format
   Related to Lack of CommonJS support #49 (comment)

2. (runtime) TypeError [ERR_INVALID_ARG_TYPE]: The "id" argument must be of type string. Received undefined (tracked this down to an issue in web-workers

3. (runtime Runtime.ImportModuleError: Error: Cannot find module './fetch.node'

To Reproduce
First issue

1. Install esbuild (yarn add -D esbuild)
2. Install [email protected]
3. Create the following file:

src/index.ts

import { auth } from '@iden3/js-iden3-auth';

export const login = async () => {
    return auth.createAuthorizationRequestWithMessage("foo", "bar", "baz", "https://localhost:3000")
};

4 Attempt to build using `yarn esbuild src/index.ts --bundle --outfile=out.js --platform=node

I get:

$ /Users/daniel/code/civicteam/polypass/node_modules/.bin/esbuild src/index.ts --bundle --outfile=out.js --platform=node
✘ [ERROR] Top-level await is currently not supported with the "cjs" output format

I can hack around this by going into node_modules/@digitalbazaar/http-client/dist/cjs/index.cjs and replacing the import of ky-universal with ky.

Building then works, but I get the other two issues at runtime. I don't think they are related to ky-universal

Expected behavior
Building should work and the createAuthorizationRequestWithMessage function should execute at runtime, resulting in a login JSON

Screenshots
If applicable, add screenshots to help explain your problem.

** Environment info (please complete the following information):**

• Mac OS
• Node 18-17
• Package version 1.0.0-beta.7
• Build cjs

Additional context
I first experienced this using serverless with AWS lambda. Steps to reproduce that:

• npx serverless create --template aws-nodejs-typescript myapp
• cd myapp
• yarn install @iden3/js-iden3-auth

then you can add the same code to the file src/functions/hello/handler.ts
then call
yarn serverless invoke local --function hello
