I want to use this in react-native app but it failed with this error about tiny-secp256k1 HOT 12 CLOSED

Metro maintainer here - thanks @junderw for calling attention to this, it's a known issue on the Metro side. See facebook/metro#815 (comment) for a workaround.

How to replace tiny-secp256k1 with @noble/secp256k1? They have different methods. I want to use it with bitcoinjs-lib

Take a look to this npm package: https://github.com/bitcoinerlab/secp256k1.

Probably better to ask this on the metro repo.

@Ella-noncelab did you have any luck with this one? I have the same issue.

from tiny-secp256k1.

It's probably an issue with hybrid packages.

1. Node uses a new exports key in package.json to denote the ESM vs. the CJS modules.
2. Some legacy tools require a main key in package.json to point to CJS.
3. Your tool probably bundles the ESM but then looks for the main key (CJS) and is probably getting confused.

But I don't know, since I am not the developer of metro

Please ask them.

I've gone ahead and reported the issue on your behalf, hopefully a solution will be found.

Thanks for the temporary solution and confirmation that the fix is on your radar.

Thanks guys! Appreciate the help.

Sorry.. I just gave up to use this. Because I only have to get addresses and keys so I use 'hdkey' package instead. https://www.npmjs.com/package/hdkey

Anyway guys, be aware that tiny-secp256k1 uses WASM which is not supported by react-native Javascript Core engine (iOS / Android). It does work on react-native-web though. Note that Android emulator may run WASM but it will not run on the actual device.

You can use the older version tiny-secp256k1@1 (which is quite slow on devices but does the job) or @noble/secp256k1 which is super fast (order-of-magnitude comparable to WASM) and works together just fine with bitcoinjs-lib.

One last thing. One problem with @noble/secp256k1 is that it is based on BigInt, which is only supported in React-Native by iOS right now, but will also join Android in the upcoming RN-0.70 release (using the new Hermes Js engine).

This helped. If you are running RN >0.70 with Hermes, this might unblock you.
