Display list very slow

[matthieup240]

I have a list with about 20k lines. To display this list, this take a very long time.
Is there a solution to resolve this inconvenient ? Thanks

This is a common issue, try enabling LazyLoading via:

const dataProvider = FirebaseDataProvider(firebaseConfig, {
  lazyLoading: {
    enabled: true,
  },
});

Related to #59

Thanks, I have tried it but when I want to do a filter, the values not already available are not founded.
Is there a solution about filters with lazyLoading enabled ?

Is there a solution with the new "count" result announced last week at the Firebase Submit ?

I experienced the same problem with slow lists and I can't yet enable lazyLoading because of the problems with filters too. I used a permanent filter as a workaround. I added this to the List component:

filter={{ collectionQuery: c => c.where('orderDate', '>=', aWeekAgo).where('orderDate', '<=', today) }}

Thanks for your answer.
Don't understand your query.
Could you adding some details please ? What is orderDate ? Is it like CreatedAt ?

[adrianbruegger]

Yes, orderDate is like a CreateAt. The whole List component looks like this:

<List actions={<ListActions />} filters={orderFilter} filter={{ collectionQuery: c => c.where('orderDate', '>=', aWeekAgo).where('orderDate', '<=', today) }} sort={{ field: 'orderDate', order: 'DESC' }} {...props}>

Hope it helps.

Ok thanks. But with this filter, I have no result....
