Prerequisites

Before setting up IELTS Mastery Hub, install the following tooling for your platform.

Required tooling

Tool	Version	Notes
Node.js	LTS (see .nvmrc, currently lts/jod)	Use nvm use to match the pinned version
npm	bundled with Node.js	Package manager used by the repo scripts
Rust	stable, via rustup	Compiled automatically by Tauri — see warning below
Tauri CLI	installed as a dev dependency (@tauri-apps/cli)	Invoked via npm run tauri / npm run tauri:build

Platform-specific Tauri system dependencies

Tauri 2 requires a native WebView on each OS:

• Windows — WebView2 (usually preinstalled on modern Windows; otherwise install the Evergreen Bootstrapper).
• Linux — webkit2gtk and libayatana-appindicator (exact packages vary by distro, e.g. webkit2gtk-4.1, libayatana-appindicator3-dev on Debian/Ubuntu).
• macOS — Xcode Command Line Tools (xcode-select --install).

See the official Tauri prerequisites guide for the full, current per-OS dependency list.

:::warning Do not build the Rust binary manually Rust is compiled automatically by Tauri tooling. Do not invoke raw cargo build/cargo run for the app binary — use npm run tauri (dev) or npm run tauri:build (production) instead. Isolated cargo commands (e.g. cargo test, cargo clippy) inside src/core/ are fine for backend-only work. :::

Verification checklist

Run these commands and confirm each one returns a version:

node -v          # should match the version in .nvmrc
npm -v
rustc --version
cargo --version

If any command is missing, revisit the installation steps for that tool before continuing to Installation & Local Setup.
