SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Connects a vanilla JavaScript frontend to a backend API with a centralized api.js wrapper, token management, and unified loading/error UX across pages.

Core Features & Use Cases

Centralized API wrapper (api.js) to standardize all fetch calls, automatic token inclusion, and uniform error handling.
JWT authentication management (auth.js) to persist login state and secure session flow.
Consistent UI helpers (ui.js) for loading states, toasts, and error presentation.
SSE-based streaming UX for chat-like interfaces and live updates.
Directory normalization and consolidation guidance to remove duplicated front-end assets and create a single source of truth.

Quick Start

Begin by wiring your HTML pages to the api.js wrapper, implement auth.js for token management, and integrate ui.js to handle loading and errors, then replace duplicated front-end code with a clean, centralized structure.

How do I connect a vanilla JavaScript frontend to a backend API?▼

Connect a vanilla JavaScript frontend to a backend API using a centralized api.js wrapper that standardizes fetch calls, includes automatic token management, and provides uniform error handling across all pages.

What's the best way to manage JWT authentication in vanilla JS?▼

Manage JWT authentication in vanilla JS by implementing a dedicated auth.js module to persist login state, secure session flows, and automatically attach tokens to centralized API fetch requests.

How do I handle loading states and error UX consistently across HTML pages?▼

Handle loading and error UX consistently across HTML pages by using shared UI helper functions that standardize loading indicators, toast notifications, and error presentation throughout the vanilla JavaScript project.

Can I implement Server-Sent Events streaming UI in a vanilla JS project?▼

Yes, you can implement Server-Sent Events (SSE) streaming UI in a vanilla JS project for chat-like interfaces and live updates by integrating the streaming data flow directly into the centralized frontend structure.

How do I consolidate duplicated frontend assets in an HTML/CSS/JS project?▼

Consolidate duplicated frontend assets in an HTML/CSS/JS project by applying directory normalization guidance to remove redundant files, creating a single source of truth for stable and centralized code.
