If you want to contribute, please start with translating the UI messages in the dictionary-<ISO 639-1 code>.json file in the data directory. Then, if you have extra energy, add the title of each item in your language to airports.json, flight-statuses.json, operators.json, poi.json, rail-directions.json, railways.json, stations.json, train-types.json in the data directory.

About Data

The data for this visualization are sourced from the Public Transportation Open Data Center, which includes station information and train timetables as well as real-time data such as train location information and status information of multiple railway lines in the Greater Tokyo area.

How to Build

First, get access tokens for the public transportation data and map tiles by signing up at Public Transportation Open Data Center and Mapbox. Then, create a file named secrets which has access tokens in the following format in the root directory of the application.

    "odpt": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

The latest version of Node.js is required. Move to the root directory of the application, run the following commands, then the script, dataset and static web page will be generated in the build directory.

npm install
npm run build-all

Finally, replace the accessToken property, which is passed to a Map constructor, with your Mapbox access token in index.html.

See the Developer Guides for more details.
