TS: yarn install freezes the system | typescript

[Revantark]

Trying to integrate tbtc-v2.ts in my project, but when i do
yarn install
after a while, the system freezes.

It is happening in the postInstall script npm rebuild

To reproduce :

1. clone tbtc-v2 repo;
2. cd typescript
3. run yarn install

this just hangs forever

@Revantark, thanks for reporting! The problem you observed sometimes happens when using Node versions greater than 14. We need to investigate it and develop a solution. As a short-term workaround, I recommend you use Node 14. Sorry for the inconvenience!

node-gyp rebuild fails on bcrypto package.

Using node 14

@Revantark, please make sure you have all OS-specific prerequisites of node-gyp listed here: https://github.com/nodejs/node-gyp#installation

@lukasz-zimnoch
I build the package successfully thanks.

But when using it in a project, I'm getting this error
Cannot find module 'bcrypto.node' from tbtc-v2.ts

I'm using yarn to link the local package to a project.

[lukasz-zimnoch]

@Revantark please try doing npm rebuild in your project just after you install all dependencies with yarn install.

[Revantark]

@lukasz-zimnoch Yes, I was doing it. But still i get Cannot find module 'bcrypto.node' error in a node project.

How to reproduce :

yarn: 1.22.19
node: v14

1. create an empty node project using npm init
2. run npm install @keep-network/tbtc-v2.ts
3. run npm rebuild
4. create a file called app.js and add the below code const tbtc = require('@keep-network/tbtc-v2.ts');
5. run npm start which runs app.js

Error: Cannot find module 'bcrypto.node'

@lukasz-zimnoch In which places do we need bcrypto in tbtc-v2.ts? In the worst case, we can copy only the code needed.

All hash computations. Copying is not an option as this is native code that must be compiled for specific targets.

bcrypto generally provides (slower) alternatives for the browser--perhaps we can copy and lean on those, if available in this case?

[lukasz-zimnoch]

We are working on removing the problematic bcrypto and bcoin dependencies. Once done, the problem described here will be solved as well. Closing this issue in favor of #695
