<p>一组标签和过滤器可以封装为一个 <strong>插件</strong>，通常发包到 NPM 来方便使用。本文介绍如何创建和使用插件。</p>
|
|
<h2 id="编写插件" class="article-heading"><a href="#编写插件" class="headerlink" title="编写插件"></a>编写插件<a class="article-anchor" href="#编写插件" aria-hidden="true"></a></h2><p>LiquidJS 插件就是一个简单的函数，它的第一个参数是 <a href="../../api/classes/liquid_.liquid.html">Liquid 类</a>，其中的 <code>this</code> 是它被注册到的 Liquid 实例。可以通过 <code>this</code> 来调用 Liquid API，比如 <a href="./register-filters-tags.html">注册标签和过滤器</a>。</p>
|
|
<p>现在我们来写一个插件并在其中注册一个过滤器，来把输入字符串转换为大写：</p>
|
|
<figure class="highlight javascript"><table><tr><td class="code"><pre><span class="line"><span class="comment">/**</span></span><br><span class="line"><span class="comment"> * Inside the plugin function, `this` refers to the Liquid instance.</span></span><br><span class="line"><span class="comment"> *</span></span><br><span class="line"><span class="comment"> * <span class="doctag">@param </span>Liquid: provides facilities to implement tags and filters.</span></span><br><span class="line"><span class="comment"> */</span></span><br><span class="line"><span class="built_in">module</span>.exports = <span class="function"><span class="keyword">function</span> (<span class="params">Liquid</span>) </span>{</span><br><span class="line"> <span class="built_in">this</span>.registerFilter(<span class="string">'upup'</span>, <span class="function"><span class="params">x</span> =></span> x.toUpperCase());</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
|
|
|
|
<p>把上述代码保存为 <code>upup.js</code>。</p>
|
|
<h2 id="使用插件" class="article-heading"><a href="#使用插件" class="headerlink" title="使用插件"></a>使用插件<a class="article-anchor" href="#使用插件" aria-hidden="true"></a></h2><p>把插件传递给 <code>.plugin()</code> 方法即可注册插件，例如：</p>
|
|
<figure class="highlight javascript"><table><tr><td class="code"><pre><span class="line"><span class="keyword">const</span> engine = <span class="keyword">new</span> Liquid()</span><br><span class="line"></span><br><span class="line">engine.plugin(<span class="built_in">require</span>(<span class="string">'./upup.js'</span>));</span><br><span class="line">engine.parseAndRender(<span class="string">'{{ "foo" | upup }}'</span>).then(<span class="built_in">console</span>.log)</span><br></pre></td></tr></table></figure>
|
|
|
|
<p>上述代码将会输出 <code>"FOO"</code>。</p>
|
|
<h2 id="插件列表" class="article-heading"><a href="#插件列表" class="headerlink" title="插件列表"></a>插件列表<a class="article-anchor" href="#插件列表" aria-hidden="true"></a></h2><p>由于本仓库只包含 <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/Shopify/liquid/">Shopify/liquid</a> 核心仓库的标签和插件（参考 <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs#differences-and-limitations">https://github.com/harttle/liquidjs#differences-and-limitations</a>），Shopify 平台上特有的插件只能通过插件来使用。</p>
