Cannot use compiled package with jest due to ESM errors about alpaca-ts HOT 16 CLOSED

I think it has to do with the CommonJS and ES6 module issues.

Jest is trying to transpile the mjs files but not able to do it correctly. We were able to fix this by directing Jest to use the cjs files:

try this in your jest.config.js:

    moduleNameMapper: {
        '@master-chief/alpaca': '<rootDir>/node_modules/@master-chief/alpaca/dist/cjs/index.cjs',
    },

from alpaca-ts.

Apologies, still haven't had time to circle back to this.

@117 hey nico much thanks. It's very nice of you to credit. If I may could you help to credit @wailinkyaww as well? We found the solution together.

P.S However the underlying issue is not really resolved, but I guess we can go with this. I met similar problems with my repos. I just ditched the whole cjs and mjs altogether, and output a commonJS distro that is compatible with both require and import interfaces:

calvintwr/not@6ce195d

Added. This issue has been an enigma to me for months! Thank you both, I'm glad we have at least a client-side solution to direct people to now. :)

This is so odd, I've used ts-jest and mocked the AlpacaClient itself in my own projects with no issue before. Now I can't seem to find a configuration that works.

I spent quite a while trying to figure out where the breakage is, but I'm totally stumped right now

When I have free time I'm going to keep looking into resolving this.

I also started getting this #77 . It's a bummer as it's failing all other tests when I use this library.
I tried Jest's config to include library.. but didn't help..

module.exports = {
  ...
  transformIgnorePatterns: ["<rootDir>/node_modules/(?!@master-chief/alpaca)"],
};

@kevindra I've done some research into it across other related issues on GitHub, could not find a way to get it behaving nicely across the board. Open to ideas though.

Thanks! I've switched to mocha and sinon now. No issues there. Spend few hours fixing this issue but couldn't so had to make this call. 🙂

Hello, I am experiencing this as well.

I want to keep this issue fresh as this is a great solution I hope not to have to depart from!

I have not yet come up with anything, but I'll report back if I do. I've got some old projects on a retired machine that might have some answers. We shall see...

It's a tough one, any help appreciated 🙏.

No luck.

In the meantime, I am using jest's mocks for the library, which is good for my needs (primarily boundary testing). I normally achieve that via spies and forget about it.

I am admittedly perplexed by this issue. It may be something I circle back to, but I've got my own problems to solve and need to keep at it. I'll stay tuned though.

Thanks for the prompt replies and attention!

I totally get it, same situation here. I've spent hours digging to solve it and it's still an enigma.

I just tested this locally.... it works. Thank you!
