# Environment variables — full reference

qiming-file-server can be configured entirely through environment variables. This document lists every supported variable.

## Precedence

From highest to lowest:

1. **CLI arguments**
2. **Process environment variables**
3. **Env files** (`.env.production`, `.env.development`, `.env.test` — loaded according to project conventions; see `src/env.*`)
4. **Built-in defaults**

## Env files

Files under `src/` are selected based on `NODE_ENV`:

## Examples

### Use production defaults but override paths

In real deployments you often keep `env.production` as the base and only override paths:

#### Example A: production + custom paths

```bash
qiming-file-server start \
  --env production \
  --port 60000 \
  PROJECT_SOURCE_DIR=/data/my-projects \
  DIST_TARGET_DIR=/var/www/my-app \
  UPLOAD_PROJECT_DIR=/data/uploads \
  LOG_BASE_DIR=/var/log/qiming
```

#### Example B: multiple instances on one host

```bash
# Instance 1 — main
qiming-file-server start \
  --env production \
  --port 60001 \
  PROJECT_SOURCE_DIR=/data/main-site \
  DIST_TARGET_DIR=/var/www/main-site

# Instance 2 — staging
qiming-file-server start \
  --env production \
  --port 60002 \
  PROJECT_SOURCE_DIR=/data/test-site \
  DIST_TARGET_DIR=/var/www/test-site

# Instance 3 — internal
qiming-file-server start \
  --env production \
  --port 60003 \
  PROJECT_SOURCE_DIR=/data/internal \
  DIST_TARGET_DIR=/var/www/internal
```

> Only pass `--port` and the paths you need; everything else comes from `env.production`.

#### Example C: override file

```bash
cat > env.override << 'EOF'
# Path overrides for production
PROJECT_SOURCE_DIR=/data/override-projects
DIST_TARGET_DIR=/var/www/override-nginx
UPLOAD_PROJECT_DIR=/data/override-uploads
LOG_BASE_DIR=/var/log/override
EOF

qiming-file-server start --env production --env-file ./env.override
```

#### Example D: Kubernetes ConfigMap

```bash
kubectl create configmap qiming-overrides \
  --from-literal=PROJECT_SOURCE_DIR=/data/k8s-projects \
  --from-literal=DIST_TARGET_DIR=/usr/share/nginx/apps \
  --from-literal=UPLOAD_PROJECT_DIR=/data/k8s-uploads \
  --from-literal=LOG_BASE_DIR=/var/log/qiming
```

Reference it in the Deployment:

```yaml
envFrom:
  - configMapRef:
      name: qiming-overrides
```

#### Example E: full path set (illustrative)

Below lists path-related variables you might set. Trim to what you actually need:

```bash
# Production with defaults from env.production, paths overridden
qiming-file-server start \
  --env production \
  --port 60000

# Or set paths explicitly
qiming-file-server start \
  --env production \
  --port 60000 \
  INIT_PROJECT_NAME_REACT=react-vite-template \
  INIT_PROJECT_NAME_VUE3=vue3-vite-template \
  INIT_PROJECT_DIR=/app/project_init \
  UPLOAD_PROJECT_DIR=/app/project_zips \
  PROJECT_SOURCE_DIR=/app/project_workspace \
  DIST_TARGET_DIR=/app/project_nginx \
  LOG_BASE_DIR=/app/logs/project_logs \
  COMPUTER_WORKSPACE_DIR=/app/computer-project-workspace \
  COMPUTER_LOG_DIR=/app/logs/computer_logs
```

#### Path variables as documented for `env.production`

| Variable | Example default | Description |
| -------- | --------------- | ----------- |
| `INIT_PROJECT_NAME_REACT` | `react-vite-template` | Built-in scaffold name for React projects |
| `INIT_PROJECT_NAME_VUE3` | `vue3-vite-template` | Built-in scaffold name for Vue3 projects |
| `INIT_PROJECT_DIR` | `/app/project_init` | Init project directory |
| `UPLOAD_PROJECT_DIR` | `/app/project_zips` | Uploaded zips |
| `PROJECT_SOURCE_DIR` | `/app/project_workspace` | Project workspace |
| `DIST_TARGET_DIR` | `/app/project_nginx` | Build output (nginx root) |
| `LOG_BASE_DIR` | `/app/logs/project_logs` | Log root |
| `COMPUTER_WORKSPACE_DIR` | `/app/computer-project-workspace` | Computer workspace |
| `COMPUTER_LOG_DIR` | `/app/logs/computer_logs` | Computer logs |

#### Path-only snippets

```bash
# 1) Only change project sources
qiming-file-server start \
  --env production \
  --port 60000 \
  PROJECT_SOURCE_DIR=/data/my-projects

# 2) Several paths
qiming-file-server start \
  --env production \
  --port 60000 \
  PROJECT_SOURCE_DIR=/data/projects \
  DIST_TARGET_DIR=/var/www/html \
  UPLOAD_PROJECT_DIR=/data/uploads

# 3) Full path set
qiming-file-server start \
  --env production \
  --port 60000 \
  INIT_PROJECT_NAME_REACT=my-react-template \
  INIT_PROJECT_NAME_VUE3=my-vue3-template \
  INIT_PROJECT_DIR=/data/init \
  UPLOAD_PROJECT_DIR=/data/zips \
  PROJECT_SOURCE_DIR=/data/workspace \
  DIST_TARGET_DIR=/var/www/nginx \
  LOG_BASE_DIR=/var/logs/project_logs \
  COMPUTER_WORKSPACE_DIR=/data/computer \
  COMPUTER_LOG_DIR=/var/logs/computer
```

> `--port` selects the HTTP port; unset path keys keep their values from `env.production`.

#### Verify overrides

```bash
qiming-file-server status
curl http://localhost:60000/health | jq

# Check startup logs for loaded env (messages are in English, e.g. "Loaded environment files: ...")
grep -E "Loaded environment|Environment configuration file" /var/log/qiming/server.log
```

### CLI overrides precedence

CLI wins over env files and plain env:

```bash
qiming-file-server start --port 8080

qiming-file-server start --env production

qiming-file-server start --env production --port 8080
```

### Shell environment

#### Linux / macOS

```bash
export PORT=8080
export NODE_ENV=production
export LOG_LEVEL=info

# Persist in ~/.bashrc or ~/.zshrc
echo 'export PORT=8080' >> ~/.bashrc
source ~/.bashrc
```

#### Windows

```cmd
set PORT=8080
set NODE_ENV=production

setx PORT 8080
setx NODE_ENV production
```

## Verifying configuration

```bash
curl http://localhost:60000/health
```

The JSON body includes the active environment name (e.g. `"env": "production"`).

## Troubleshooting

### Changes not applied

1. Confirm the correct env file path and `NODE_ENV`.
2. Variable names are case-sensitive.
3. Validate YAML/JSON if you embed config in manifests.
4. Read server logs for load errors.

### Port already in use

If `PORT` is taken, startup fails. Pick another port or free the listener.

### Permissions

Ensure log and data directories are writable:

```bash
chmod -R 755 /path/to/logs
mkdir -p /path/to/logs /path/to/projects
```

### Docker env not visible

Pass variables with `environment:` or `envFrom:`:

```yaml
environment:
  - NODE_ENV=production
  - PORT=60000

envFrom:
  - configMapRef:
      name: my-config
```
