# Developer Setup Guide
> Before anything else, please read the [[Contributing]] guidelines.
## Prerequisites
- Node.js 22+
- npm
- Git
- A GitHub account
---
## 1. Fork & Clone the Repository
Go to the [TREK repository](https://github.com/mauriceboe/TREK) and click **Fork** to create your own copy.
Then clone your fork locally:
```bash
# Clone your fork, checking out the dev branch
git clone -b dev git@github.com:your-username/TREK.git
cd TREK
```
---
## 2. Configure Git Remotes
Add the original repository as `upstream` so you can pull in future updates:
```bash
git remote add upstream git@github.com:mauriceboe/TREK.git
```
You should now have two remotes:
| Remote | URL | Purpose |
|------------|----------------------------------------------|--------------------------------|
| `origin` | `git@github.com:your-username/TREK.git` | Your fork — push changes here |
| `upstream` | `git@github.com:mauriceboe/TREK.git` | Main repo — pull updates from here |
---
## 3. Keep Your Fork Up to Date
Before starting any work, make sure your local `dev` branch is in sync with upstream:
```bash
git fetch upstream
git rebase upstream/dev # or: git merge upstream/dev
```
---
## 4. Create a Feature Branch
Working on a dedicated branch keeps your changes isolated and makes PRs easier to review:
```bash
# Create a new branch off of dev
git checkout -b fix/my-changes origin/dev
```
Branch naming conventions:
- `feat/short-description` for new features
- `fix/short-description` for bug fixes
- `chore/short-description` for maintenance tasks
---
## 5. Install Dependencies
The repo is an npm workspace monorepo. One command at the root installs everything:
```bash
npm ci
```
---
## 6. Optional: KItinerary (Booking Import)
The booking-confirmation import feature uses [KDE KItinerary](https://apps.kde.org/itinerary/) to parse travel documents. The server works without it, but the import endpoint will be non-functional.
### Linux — amd64
Download the static binary from the KDE CDN and verify the checksum:
```bash
wget -qO /tmp/ki.tgz https://cdn.kde.org/ci-builds/pim/kitinerary/release-26.04/linux/kitinerary-extractor-x86_64-26.04.0.tgz
echo "b7058d98990053c7b61847fef0c21e02d59b60e323e2b171ca210b682334e801 /tmp/ki.tgz" | sha256sum -c
sudo tar -xz -C /usr/local -f /tmp/ki.tgz bin/kitinerary-extractor share/locale
rm /tmp/ki.tgz
```
### Linux — arm64
```bash
sudo apt-get install -y libkitinerary-bin
sudo ln -sf "$(find /usr/lib -name kitinerary-extractor -type f | head -1)" /usr/local/bin/kitinerary-extractor
```
### Environment variables
Add these to your local `.env` (or export them before starting the server):
```bash
# Required: path to the extractor binary
KITINERARY_EXTRACTOR_PATH=/usr/local/bin/kitinerary-extractor
# Prevent Qt from probing for a display in headless/server environments
QT_QPA_PLATFORM=offscreen
# KDE cache directory (avoids writing to $HOME)
XDG_CACHE_HOME=/tmp/kf6-cache
```
You can override `KITINERARY_EXTRACTOR_PATH` if you installed the binary to a different location.

## 7. Available Scripts
### Root (`/`)
These commands run across all workspaces at once and are the recommended way to work:
| Command | Description |
|----------------------|---------------------------------------------------------------------|
| `npm run dev` | Build shared, then start shared (watch), server, and client together via `concurrently` |
| `npm run build` | Build shared → server → client in order |
| `npm test` | Run tests in shared, server, and client |
| `npm run test:cov` | Run coverage for server and client |
| `npm run test:e2e` | Run end-to-end tests (server) |
| `npm run lint` | Lint shared, server, and client |
| `npm run format` | Format shared, server, and client |
| `npm run format:check` | Check formatting across all workspaces |
### Shared (`/shared`)
The `@trek/shared` package is the single source of truth for code shared between the client and server. It holds the **Zod schemas that define the API contracts** (request/response shapes, common primitives, pagination) and the **i18n translation layer** (per-language keys and types). Both workspaces import from it, so schema and translation changes propagate to both sides from one place.
> **Tip:** run `npm run i18n:parity` (or `i18n:parity:strict`) in this package to verify every locale exposes the same translation keys — the CI parity gate runs the strict variant.
| Command | Description |
|-----------------------------|--------------------------------------|
| `npm run build` | Compile shared package (tsup) |
| `npm run build:watch` | Compile in watch mode |
| `npm test` | Run tests |
| `npm run typecheck` | Type-check without emitting |
| `npm run i18n:parity` | Check locale key parity |
| `npm run i18n:parity:strict`| Strict locale key parity (CI gate) |
| `npm run lint` | Lint source |
| `npm run format` | Format source |
### Root (`/`)
These commands run across all workspaces at once and are the recommended way to work:
| Command | Description |
|----------------------|---------------------------------------------------------------------|
| `npm run dev` | Build shared, then start shared (watch), server, and client together via `concurrently` |
| `npm run build` | Build shared → server → client in order |
| `npm test` | Run tests in shared, server, and client |
| `npm run test:cov` | Run coverage for server and client |
| `npm run test:e2e` | Run end-to-end tests (server) |
| `npm run lint` | Lint shared, server, and client |
| `npm run format` | Format shared, server, and client |
| `npm run format:check` | Check formatting across all workspaces |
### Shared (`/shared`)
The `@trek/shared` package is the single source of truth for code shared between the client and server. It currently holds **Zod schemas that define API contracts** (request/response shapes, common primitives, pagination). Both workspaces import from it so schema changes automatically propagate to both sides.
> **Upcoming:** the i18n translation layer will be migrated into this package so that translation keys and types are enforced across the stack from one place.
| Command | Description |
|------------------------|------------------------------------|
| `npm run build` | Compile shared package (tsup) |
| `npm run build:watch` | Compile in watch mode |
| `npm test` | Run tests |
| `npm run typecheck` | Type-check without emitting |
| `npm run lint` | Lint source |
| `npm run format` | Format source |
### Server (`/server`)
| Command | Description |
|----------------------------|------------------------------------------|
| `npm start` | Start the server (production) |
| `npm run dev` | Start the server in watch mode |
| `npm run build` | Compile server |
| `npm run typecheck` | Type-check without emitting |
| `npm test` | Run all tests |
| `npm run test:unit` | Run unit tests only |
| `npm run test:integration` | Run integration tests |
| `npm run test:ws` | Run WebSocket tests |
| `npm run test:e2e` | Run end-to-end tests |

| `npm run build` | Build for production (runs icon generation first) |
| `npm run preview` | Preview the production build locally |
| `npm test` | Run all tests |
| `npm run test:unit` | Run unit tests only |

## 8. Commit & Push Your Changes
```bash
git add .
git commit -m "fix: describe your change"
# Push to your fork's dev branch
git push origin fix/my-changes
# Or if working directly on dev
git push origin dev
```
Then open a Pull Request from your fork to `mauriceboe/TREK` targeting the `dev` branch. If your PR only modifies files under `wiki/`, it is exempt from branch enforcement and may target any branch.
---
## Tips
- Always branch off from an up-to-date `dev` — run `git fetch upstream && git rebase upstream/dev` before starting new work.
- Run tests before pushing: `npm test` at the repo root runs all workspaces.
- Follow the commit message conventions described in the [[Contributing]] guidelines.
