@grams-dev/core

Welcome to the @grams-dev/core package — your comprehensive toolkit tailored for the Grams ecosystem. This package houses essential modules, making it effortless to fuel cross-platform applications with unmatched efficiency.

Prerequisites

Before diving in, ensure you have the following tools installed:

• Python <3.11
• Yarn: Install via npm install -g yarn
• Visual C++ Build Tools: Essential for crafting native modules. Download here.
• Rust & Cargo: These are vital for certain cryptographic functionalities offered by IOTA. Here's an installation guide.

For Windows users, remember to also install LLVM. It's also likely you'll need to configure an environment variable RUSTFLAGS with the value -C target-feature=+crt-static.

Bindings

Venture into the bindings directory for nuanced implementations.

• Node.js: Seamlessly infuse core functionalities into Node.js applications.
• WebAssembly (Wasm): Paves the way for high-performance execution in web-native environments.

Which bindings to choose?

With @grams-dev/core, we offer dedicated bindings to cater to various platforms. Understanding the differences between Wasm and Node.js bindings can be crucial:

| | Wasm bindings | Node.js bindings | |:--------------|:-----------------:|:---------------------:| | Environment | Node.js, browsers | Node.js | | Installation | - | Rust, Cargo required* | | Performance | ✔️ | ✔️✔️ | | Ledger Nano | ❌ | ✔️ | | Rocksdb | ❌ | ✔️ | | Stronghold | ❌ | ✔️ |

tl;dr: Opt for Node.js bindings whenever feasible, especially in server environments. On the other hand, Wasm bindings offer portability, making them suitable for browser environments.

Installation

Add the core package to your project via npm:

npm install @grams-dev/core

Or with yarn:

yarn add @grams-dev/core
