# 12306 Train Query

Query train schedules and remaining tickets from China Railway 12306.

## Query Tickets

```bash
node {baseDir}/scripts/query.mjs <from> <to> [options]
```

- HTML mode (default): writes file, prints path to stdout
- Markdown mode (`-f md`): prints table to stdout

### Examples

```bash
# All trains from Beijing to Shanghai (defaults to today)
node {baseDir}/scripts/query.mjs 北京 上海

# Markdown table output (to stdout, good for chat)
node {baseDir}/scripts/query.mjs 北京 上海 -t G -f md

# Morning departures, 2h max, with second class available
node {baseDir}/scripts/query.mjs 上海 杭州 -t G --depart 06:00-12:00 --max-duration 1h --seat ze

# Only bookable trains arriving before 6pm
node {baseDir}/scripts/query.mjs 深圳 长沙 --available --arrive -18:00

# Custom output path
node {baseDir}/scripts/query.mjs 广州 武汉 -o /tmp/tickets.html

# JSON output (to stdout)
node {baseDir}/scripts/query.mjs 广州 武汉 --json
```

### Options

- `-d, --date <YYYY-MM-DD>`: Travel date (default: today)
- `-t, --type <G|D|Z|T|K>`: Filter train types (combinable, e.g. `GD`)

- `--arrive <HH:MM-HH:MM>`: Arrive time range (e.g. `-18:00`, `14:00-20:00`)
- `--max-duration <duration>`: Max travel time (e.g. `2h`, `90m`, `1h30m`)
- `--available`: Only show bookable trains
- `--seat <types>`: Only show trains with tickets for given seat types (comma-separated: `swz,zy,ze,rw,dw,yw,yz,wz`)
- `-f, --format <html|md>`: Output format — `html` (default, saves file) or `md` (markdown table to stdout)
- `-o, --output <path>`: Output file path, html mode only (default: `{baseDir}/data/<from>-<to>-<date>.html`)
- `--json`: Output raw JSON to stdout
