Below is a step‑by‑step guide to produce a system design diagram tailored to the “sonic‑client‑web” project, the Vue 3 front‑end for the Sonic Cloud real‑device platform.

1. Identify Project Type & Purpose

• It’s a Single‑Page Application (SPA) built with Vue 3 + Element Plus, designed as the web front end for Sonic Cloud’s real‑mobile‑device testing platform.

• It runs in the user’s browser, communicates over HTTP/REST and WebSocket to the Sonic back‑end, and displays remote device screens (via scrcpy).

2. Analyze File Structure

• Top‑level:

– index.html, main.js, vite.config.js → SPA bootstrap & build

– nginx.conf → reverse‑proxy/static server config

– Dockerfile → containerization

• src/ → application code:

– src/router → route definitions

– src/store → Vuex (central state)

– src/http/axios.js → HTTP client setup

– src/lib/audio‑processor/socket.js → WebSocket audio channel

– src/components & src/views → UI building blocks (components and page views)

– src/config, src/utils, src/locales → cross‑cutting modules (i18n, caching, locale)

3. Examine README for Tech Stack & Runtime

• Vue 3.2.x, Element Plus, Vite, Docker

• Deployed as static assets behind Nginx, packaged via Docker

• Communicates with sonic‑server APIs & WebSocket endpoints

4. Main Components & Their Interactions

a. Client Browser (SPA)

– Router module directs to Views → composed of Components

– Store (Vuex) holds application state

– HTTP layer (axios) → REST calls to sonic-server APIs

– WebSocket (audio‑processor) → real‑time audio stream

– i18n module → localized UI

b. Static Server / Reverse Proxy

– Nginx serves compiled assets (CSS/JS/HTML)

– Routes API requests (optionally proxy to sonic-server)

c. Backend Services

– sonic-server REST API

– WebSocket/audio‑processor endpoint

– scrcpy service for remote screen streaming

5. Architectural Patterns & Design Principles

• Component‑based UI (Vue’s MVVM)

• Centralized state management (Vuex)

• Modular directory layout (router, store, components, views, utils)

• Separation of concerns:

– Presentation (components/views) vs. business logic (store/actions) vs. services (http, socket)

• Containerization (Docker) + static hosting (Nginx)

6. Diagramming Guidelines

- Draw high‑level boxes for:

[Browser SPA] → [Nginx Container] → [Backend Services]

- Inside the SPA box, subdivide into:

• Router & Views Layer

• Component Library

• Store (Vuex)

• HTTP Client & WebSocket Client

• Utils / i18n / Config

- Show directional arrows:

• HTTP REST calls from HTTP Client to Backend REST API

• WebSocket connections from audio‑processor to Backend WS

• User interactions from Browser UI to Router / Store

- Color‑code or shape‑code:

• Blue boxes for UI layers

• Green for state & services

• Orange for external/backend services

- Label all arrows with protocols (HTTP, WS) and data types (JSON, audio stream).

7. Tailoring to This Front‑end Project

- Emphasize the SPA’s boundary: index.html → main.js → mounts App.vue

- Show how Dockerfile builds the SPA and Nginx serves it

- Highlight the audio‑processor library’s WebSocket channel for device audio

- Call out the scrcpy integration under src/views/RemoteEmulator

8. Key Elements to Include

• Clear component boxes: Browser, SPA sub‑modules, Nginx, Backend API, WebSocket server

• Directional arrows with protocol labels

• Legend or color key distinguishing UI vs. state vs. external services

• Annotations for important files (e.g., nginx.conf, Dockerfile, vite.config.js)

By following this outline, you’ll create a detailed system design diagram that accurately reflects how the Vue SPA is structured internally and how it interacts externally, capturing all essential architectural elements without over‑splitting.
