Welcome to your go-to guide for diving into IOV-Core, an outstanding cross-platform TypeScript library packed with core functionalities for building CLI clients, automated scripts, and BCP-proxy apps. In this article, we will break down the primary functionalities, ensure a smooth setup process, and address common troubleshooting scenarios.

Main Functionalities

• Solid cryptocurrency library with HD support for ed25519.
• Secure private key management with encrypted local storage.
• Type-safe adaptor for Tendermint RPC server communication.
• Tools for querying and creating transactions in the IOV BNS blockchain.
• High-level controllers for managing user profiles across multiple blockchains.
• Integration with REPL for interactive coding and quick prototyping.

Getting Started

Before we jump into the code, think of IOV-Core as the toolkit you need to set up a successful construction project. Just as a builder uses blueprints, tools, and materials to create a sturdy building, you will need IOV-Core’s libraries and components to create robust applications.

To start building, follow these steps:

1. Ensure you have Node.js (10.13+) and Yarn installed (not npm).
2. Run yarn install in your terminal to install dependencies.
3. Build the project by executing yarn build.
4. Run tests using yarn test to ensure everything is functioning correctly.

Building and Testing

IOV-Core relies on the compiled code from Node packages, ensuring compatibility with modern browsers. If you face issues, you may want to check your environment and ensure that you haven’t installed dependencies using npm, as that can lead to problems. Instead, stick to Yarn throughout your development.

Integration Tests

When you’re ready to test integrations, especially with Tendermint or the BNS blockchain, you need to set up a test server. If you’re using Docker, make sure it’s properly configured for your environment.

Steps for Running Tests

Here’s the process:

1. For Tendermint, use the commands:

export TENDERMINT_ENABLED=1
cd packages/iov-tendermint-rpc
yarn test
cd ....unset TENDERMINT_ENABLED

2. For BNS, run:

cd packages/iov-bns
yarn test

Troubleshooting

If you encounter issues, here are some common troubleshooting tips:

• Libusb fails to build: Ensure you have the necessary dependencies installed (for Ubuntu, run: sudo apt-get install libudev-dev libusb-1.0-0 libusb-1.0-0-dev).
• Docker fails to run a test server: Ensure that your $TMPDIR is added to the shared paths in Docker preferences.
• CI rejects PR: Ensure you ran yarn test in all directories where code was modified.
