<p>开启严格模式，仅需在创建 store 的时候传入 <code>strict: true</code>：</p>
<pre class="language-"><code class="lang-js"><span class="token keyword">const</span> store <span class="token operator">=</span> <span class="token keyword">new</span> <span class="token class-name">Vuex<span class="token punctuation">.</span>Store</span><span class="token punctuation">(</span><span class="token punctuation">{</span>
<span class="token comment" spellcheck="true">// ...</span>
strict<span class="token punctuation">:</span> <span class="token boolean">true</span>
<span class="token punctuation">}</span><span class="token punctuation">)</span>
</code></pre>
<p>在严格模式下，无论何时发生了状态变更且不是由 mutation 函数引起的，将会抛出错误。这能保证所有的状态变更都能被调试工具跟踪到。</p>
<h3 id="开发环境与发布环境">开发环境与发布环境</h3>
<p><strong>不要在发布环境下启用严格模式！</strong>严格模式会深度监测状态树来检测不合规的状态变更——请确保在发布环境下关闭严格模式，以避免性能损失。</p>
<p>类似于插件，我们可以让构建工具来处理这种情况：</p>
<pre class="language-"><code class="lang-js"><span class="token keyword">const</span> store <span class="token operator">=</span> <span class="token keyword">new</span> <span class="token class-name">Vuex<span class="token punctuation">.</span>Store</span><span class="token punctuation">(</span><span class="token punctuation">{</span>
