在前一篇文章中,我們探討了 TypeScript 的導入策略,建立了型別安全的開發基礎。今天我們將面對前端開發中最關鍵的架構決策:框架選擇。在當今的前端生態中,React、Vue、Angular 三大框架形成了穩固的「三強鼎立」格局,共同佔據了超過 76% 的市場份額,在 2025 年呈現更加成熟穩定的發展態勢。每個框架都代表著不同的技術哲學和開發模式,這個決定將深刻影響你的開發體驗、團隊協作模式,以及專案的長期維護成本。
三大框架的市場地位與技術定位
當今前端開發生態已經形成了穩定的「三強鼎立」格局,React、Vue、Angular 各自在不同領域建立了自己的優勢地位:
排名 | 框架 | 市場佔有率 | GitHub Stars | NPM 週下載量 | 設計哲學 |
---|---|---|---|---|---|
🥇 | React | 39.5% | 235k+ | 22M+ | 函式式組件化 |
🥈 | Vue | 20.1% | 215k+ | 5.2M+ | 漸進式框架 |
🥉 | Angular | 16.8% | 98k+ | 3.5M+ | 企業級全功能框架 |
📊 市場總計:三大框架佔據 76.4% 的市場份額

語法糖普及讓我們透過同一個功能的不同實作方式,來理解三大框架的核心差異:
// 同一個使用者資料組件的三種實作方式
// === React:函式式 + JSX ===

React 的核心價值主張
// React 的進階模式:自定義 Hook + Context
import { createContext, useContext, useReducer, useEffect } from 'react';
// 狀態管理
const UserContext = createContext();
function userReducer(state, action) {
switch (action.type) {
case 'LOADING':
return { ...state, loading: true, error: null };
case 'SUCCESS':
return { ...state, loading: false, user: action.payload, error: null };
case 'ERROR':
return { ...state, loading: false, error: action.payload };
default:
return state;
}
}
// 自定義 Hook
function useUser(userId) {
const [state, dispatch] = useReducer(userReducer, {
user: null,
loading: false,
error: null
});
useEffect(() => {
if (!userId) return;
const loadUser = async () => {
dispatch({ type: 'LOADING' });
try {
const user = await fetchUser(userId);
dispatch({ type: 'SUCCESS', payload: user });
} catch (error) {
dispatch({ type: 'ERROR', payload: error.message });
}
};
loadUser();
}, [userId]);
return state;
}
// 組件使用
function UserProfile({ userId }) {
const { user, loading, error } = useUser(userId);
if (loading) return <LoadingSpinner />;
if (error) return <ErrorMessage error={error} />;
if (!user) return <EmptyState />;
return (
<div className="user-profile">
<UserHeader user={user} />
<UserDetails user={user} />
<UserActions user={user} />
</div>
);
}

Angular 的技術特點(2025年革新):
在深入技術細節之前,讓我們先解釋為什麼本文主要聚焦於這三個技術方案,以及其他框架的考量因素。
🎯 框架選擇的戰略考量
框架 | 市場佔有率 | GitHub Stars | NPM 週下載量 | 企業採用率 | 2025年關鍵趨勢 |
---|---|---|---|---|---|
React | 39.5% | 235k+ | 22M+ | 極高 | Server Components 主流化 |
Vue | 20.1% | 215k+ | 5.2M+ | 持續上升 | Vapor Mode 編譯優化 |
Angular | 16.8% | 98k+ | 3.5M+ | 極高 | Signals 響應式革新 |
三大框架總計市場佔有率:76.4%
框架 | 市場佔有率 | 目標場景 | 學習曲線 | 核心特色 | 2025年發展重點 |
---|---|---|---|---|---|
Svelte | 6.2% | 效能優先、輕量應用 | 平緩 | 編譯時優化 | SvelteKit 企業採用增加 |
SolidJS | 2.8% | 極致效能 | 中等 | 細粒度響應式 | 效能敏感場景採用率提升 |
Vanilla JS | 基礎技術 | 標準化、高效能 | 較陡峭 | 回歸 Web 本質 | Web Components 標準化成熟 |
為什麼沒有將 Vanilla JS 列為主要選擇?
// 現代 Vanilla JS 開發模式示範
class TodoApp extends HTMLElement {
constructor() {
super();
this.attachShadow({ mode: 'open' });
this.state = {
todos: [],
filter: 'all'
};
this.render();
}
connectedCallback() {
this.addEventListener('todo-add', this.handleAddTodo);
this.addEventListener('todo-toggle', this.handleToggleTodo);
}
handleAddTodo(event) {
const newTodo = {
id: Date.now(),
text: event.detail.text,
completed: false
};
this.state.todos = [...this.state.todos, newTodo];
this.render();
}
render() {
this.shadowRoot.innerHTML = `
<style>
.todo-app { padding: 20px; }
.todo-item { padding: 10px; border-bottom: 1px solid #eee; }
.completed { text-decoration: line-through; opacity: 0.6; }
</style>
<div class="todo-app">
<todo-input></todo-input>
<todo-list .todos="${this.state.todos}"></todo-list>
</div>
`;
}
}
customElements.define('todo-app', TodoApp);
Vanilla JS 的考量因素:
適用場景:
<!-- Svelte 的簡潔語法示範 -->
<script>
export let userId;
let user = null;
let loading = true;
let error = null;
// 響應式語句 - Svelte 的核心特色
$: if (userId) {
loadUser(userId);
}
$: displayName = user ? `${user.firstName} ${user.lastName}` : '';
async function loadUser(id) {
loading = true;
error = null;
try {
const response = await fetch(`/api/users/${id}`);
user = await response.json();
} catch (err) {
error = err.message;
} finally {
loading = false;
}
}
</script>
<div class="user-profile">

<div class="loading">載入中...</div>
{:else if error}
<div class="error">錯誤:{error}</div>
{:else if user}
<h2>{displayName}</h2>

<p>部門: {user.department}</p>
{/if}
</div>
<style>
.user-profile {
padding: 20px;
border: 1px solid #ddd;
border-radius: 8px;
}
.loading, .error {
text-align: center;
padding: 20px;
}
.error {
color: #e74c3c;
}
</style>
為什麼 Svelte 不在主要比較範圍?
Svelte 的優勢與定位:
// SolidJS 的細粒度響應式示範
import { createSignal, createEffect, createMemo } from 'solid-js';
function UserProfile(props) {
const [user, setUser] = createSignal(null);
const [loading, setLoading] = createSignal(true);
const [error, setError] = createSignal(null);
// 細粒度響應式更新
const displayName = createMemo(() => {
const userData = user();
return userData ? `${userData.firstName} ${userData.lastName}` : '';
});
createEffect(async () => {
if (props.userId) {
setLoading(true);
setError(null);
try {
const response = await fetch(`/api/users/${props.userId}`);
const userData = await response.json();
setUser(userData);
} catch (err) {
setError(err.message);
} finally {
setLoading(false);
}
}
});
return (
<div class="user-profile">
{loading() ? (
<div class="loading">載入中...</div>
) : error() ? (

<h2>{displayName()}</h2>
<p>Email: {user().email}</p>

核心概念: React、Vue、Angular 形成穩固的「三強鼎立」格局,React 主導複雜應用和豐富生態,Vue 專精快速開發和學習友好,Angular 專注企業級完整解決方案
關鍵技術: 透過多維度評估模型進行客觀決策,重點考量學習曲線、開發效率、生態豐富度、企業級支援等核心要素
實踐要點: 框架選擇是長期技術投資,需基於專案特性、團隊現狀、維護週期等實際情況,並充分評估遷移成本和人才市場因素
在你目前的專案中,如果要重新選擇框架,你會基於哪些標準來評估?除了三大框架,什麼情況下你會考慮 Svelte 或 SolidJS 等新興選擇?
三大框架在你的職涯規劃中各自扮演什麼角色?你會如何平衡學習主流框架與關注新興技術的時間分配?
如何向非技術主管解釋為什麼選擇成熟框架而非最新技術?你會提供哪些風險評估和ROI數據來支持決策?
面對 Vanilla JS 的回歸趨勢和 Web Components 標準化,你認為框架的未來發展方向是什麼?何時值得投資學習原生 Web 技術?
如果你的團隊對新興框架(如 Svelte、SolidJS)有興趣,你會如何制定試驗和評估計劃?在什麼條件下才考慮在生產環境中採用?
