tfl-cli

Use tfl for London transport: tube status, journey planning, disruptions, live arrivals, bike availability, and stop search.

Setup

• npm install -g @shan8851/tfl-cli
• Optional: set TFL_APP_KEY for higher rate limits (basic usage works without any key)

Status

• All lines: tfl status
• Specific line: tfl status jubilee
• Filter by mode: tfl status --mode tube,dlr

Disruptions

• Current disruptions: tfl disruptions
• Specific line: tfl disruptions piccadilly

Journey Planning

• Station to station: tfl route "waterloo" "kings cross"
• Postcode to postcode: tfl route "SE1 9SG" "EC2R 8AH"
• Arrive by time: tfl route "waterloo" "bank" --arrive-by --time 09:00
• With preferences: tfl route "waterloo" "paddington" --preference least-interchange
• Via a waypoint: tfl route "waterloo" "paddington" --via "bank"
• Project one route field: tfl route "SE1 9SG" "EC2R 8AH" --output journeys.0.durationMinutes
• Project route legs: tfl route "waterloo" "canary wharf" --output journeys.0.legs

Arrivals

• Next arrivals: tfl arrivals "waterloo"
• Specific line: tfl arrivals "king's cross" --line northern --limit 5
• Filter direction: tfl arrivals "waterloo" --direction inbound
• Project one value: tfl arrivals "waterloo" --output arrivals.0.timeToStationSeconds
• Project in JSON: tfl arrivals "waterloo" --json --output arrivals.0.lineName

Bikes

• Near postcode: tfl bikes "SE1 9SG"
• Custom radius: tfl bikes "waterloo" --radius 750 --limit 5
• Project one value: tfl bikes "SE1 9SG" --output bikePoints.0.bikes
• Project one subtree: tfl bikes "SE1 9SG" --output bikePoints.0

Search

• Find stops/stations: tfl search stops "paddington"
• Limit results: tfl search stops "paddington" --limit 10

Output

• All commands default to text in TTY and JSON when piped
• Force JSON: tfl status --json
• Force text: tfl status --text
• Disable colour: tfl --no-color status
• Success envelope: { ok, schemaVersion, command, requestedAt, data }
• Error envelope: { ok, schemaVersion, command, requestedAt, error }

Agent Notes

• --output is available on route, arrivals, and bikes
• Paths use dot notation with zero-based array indexes, for example journeys.0.durationMinutes or arrivals.0.lineName
• In text mode, scalar projections print just the value
• In text mode, object or array projections print plain pretty JSON
• Projection errors are structured: malformed paths return INVALID_INPUT, missing paths return NOT_FOUND

Notes

• No API key required for basic usage
• Accepts station names, postcodes (SE1 9SG), coordinates (51.50,-0.12), and TfL stop IDs
• Status and disruptions cover tube, overground, DLR, and Elizabeth line
• Exit codes: 0 success, 2 bad input or ambiguity, 3 upstream failure, 4 internal error
• When a station name is ambiguous, the error includes candidate suggestions
