# Modrinth Monorepo

This is the Modrinth monorepo — it contains all Modrinth projects, both frontend and backend. When entering a project, either to edit or analyse, you should read it's CLAUDE.md.

## Architecture

- **Monorepo tooling:** [Turborepo](https://turbo.build/) (`turbo.jsonc`) + [pnpm workspaces](https://pnpm.io/workspaces) (`pnpm-workspace.yaml`)
- **Frontend:** Vue 3 / Nuxt 3, Tailwind CSS v3
- **Backend:** Rust (Labrinth API), Postgres, Clickhouse
- **Indentation:** Use TAB everywhere, never spaces

## Pre-PR Commands

Run these from the **root** folder before opening a pull request - do not run these after each prompt the user gives you, only run when asked, ask the user a question if they want to run it if the user indicates that they are about to create a pull request.

- **Website:** `pnpm prepr:frontend:web`
- **App frontend:** `pnpm prepr:frontend:app`
- **Frontend libs:** `pnpm prepr:frontend:lib`
- **All frontend (app+web):** `pnpm prepr`
- **Labrinth (backend):** See `apps/labrinth/CLAUDE.md`

The website and app `prepr` commands

## Dev Commands

- **Website:** `pnpm web:dev` (copy `.env` template in `apps/frontend/` first)
- **App:** `pnpm app:dev` (copy `.env` template in `packages/app-lib/` first)
- **Storybook (packages/ui):** `pnpm storybook`

## Project-Specific Instructions

Each project may have its own `CLAUDE.md` with detailed instructions:

- [`apps/labrinth/CLAUDE.md`](apps/labrinth/CLAUDE.md) — Backend API
- [`apps/frontend/CLAUDE.md`](apps/frontend/CLAUDE.md) - Frontend Website

## Code Guidelines

### Comments
- DO NOT use "heading" comments like: // === Helper methods === .
- Use doc comments, but avoid inline comments unless ABSOLUTELY necessary for clarity. Code should aim to be self documenting!

## Bash Guidelines

### Output handling
- DO NOT pipe output through `head`, `tail`, `less`, or `more`
- NEVER use `| head -n X` or `| tail -n X` to truncate output
- Run commands directly without pipes when possible
- If you need to limit output, use command-specific flags (e.g. `git log -n 10` instead of `git log | head -10`)
- ALWAYS read the full output — never pipe through filters

### General
- Do not create new non-source code files (e.g. Bash scripts, SQL scripts) unless explicitly prompted to
