SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill implements optimisticCommand for blocking one-time actions with immediate UI updates and automatic rollback on failure.

Core Features & Use Cases

  • Supports optimistic updates for creating, deleting, and updating items, as well as form submissions, file uploads, and payments.
  • Updates the UI instantly, runs the server operation asynchronously, and rolls back on failure.
  • Provides a clear flow: identify the operation, apply an optimistic update, perform the server call, and optionally reconcile with server data or customize rollback.

Quick Start

Define an optimisticCommand workflow in your Cubit to update the UI immediately and reconcile with the server response.

FAQPage Schema
How do I implement optimistic UI updates with automatic rollback in a Cubit?

Implement optimistic updates by applying an optimistic value to your state, sending the command to the server asynchronously, and automatically rolling back the state if the server operation fails. This provides immediate UI feedback for blocking actions.

What is optimistic state management for one-time actions like form submissions?

Optimistic state management for one-time actions updates the UI instantly while running server operations asynchronously in the background. If the server operation fails, the state automatically rolls back to its previous value to ensure data consistency.

Can I use optimistic updates for file uploads and payments, or just item creation?

You can use optimistic updates for file uploads, payments, form submissions, and creating, deleting, or updating items. The workflow applies immediate UI changes across various blocking one-time actions and rolls back safely on failure.

What parameters are required to set up an optimistic command workflow?

Setting up an optimistic command workflow requires a key, an optimistic value, a function to get the value from state, a function to apply the value to state, and a function to send the command to the server. Optional hooks handle server response, rollback, and reload logic.

How does server synchronization work after applying an optimistic update?

After applying an optimistic update to the UI, the workflow sends the command to the server asynchronously. You can use optional hooks to reconcile the local state with the actual server response or execute custom reload logic upon successful synchronization.

When should I avoid optimistic updates for state management?

Avoid optimistic updates for actions where immediate UI feedback is undesirable or when the server operation has a high probability of failure. Because optimistic updates instantly change the UI, frequent failures will cause UI flickering from constant state rollbacks.
