options.strict is enabled then errors will be thrown. Note when NOT **prodcution** strict is automatically enabled when strict is undefined. This is done to ensure there are not duplicate registrations and routes in a production environment.\n\nListening to all events for a given group.\n\n```ts\ntensil.on(`route`, (type, ...args) => {\n // do something with route.\n});\n```\n\nTo listen to a specific event type you combine the event with the type separated by a colon. When listening to a specific event type the **type** is removed from the first argument.\n\n```ts\ntensil.on(`route:mounted`, (...args) => {\n // do something with route.\n});\n```\n\nYou can also listen to ALL events as follows:\n\n\n```ts\ntensil.on(`*`, (event, type, ...args) => {\n // do something with event.\n});\n```\n\n| Event | Type | Value1 | Value2 |
