Wunderlist -> Todoist

This is a migration helper from Wunderlist to Todoist.

Collects tasks in Wunderlist and imports them to a Todoist project with the same name with its list in Wunderlist. If there is not a corresponding project in Todoist, it creates a new project.

Recurrence is supported. Subtask is not supported.

Requirements

• Node.js which supports async and await

Usage

Run npm install.

Create ./secret.json and fill your tokens as below:

{
  "wunderlist": {
    "clientID": "...",
    "accessToken": "..."
  },
  "todoist": {
    "token": "..."
  }
}

Run node --harmony-async-await fetch_tasks_from_wunderlist.js, then tasks in Wunderlist will be exported into ./task.json.

Run node --harmony-async-await add_tasks_to_todoist.js to import ./task.json to your Todoist account.
