Your implementation is pretty close what you are trying to do. You have method
public getLength(){
this.todoService.lengthTodos();
}
Which is reading the todo length from the service. You just need to return the value from service class. Make the following changes and use this function in html.
public getLength(){
return this.allTodos.filter(todo => !todo.completed).length;
}
Change in the html of footer component
<span class="todo-count"><strong>{{getLength()}}</strong> item left</span>
