+title: 为 Astro 加上在新标签页打开链接的功能
+published: 2025-08-31
+tags: ["插件", "网站"]
+description: 原版 Astro（包括 Fuwari） 中，打开外部链接是在当前页面打开，而非在新标签页打开。这个插件完美适配了这个需求，让我们的链接可以在新的标签页打开。
+image: ../assets/images/newtab-link-npm-plugin-info-1.png
+customcover: ../assets/images/newtab-link-npm-plugin-info-2.png
+showcover: false
+category: 教程
+---
+
+# 前言
+看标题可能不明白在说什么。但是如果我放出这两个链接让你点，你应该知道是什么意思。
+
+<a href="https://www.bing.com">打开必应</a> &nbsp; | &nbsp; <a href="https://www.bing.com" target="_blank">在新标签页打开必应</a>
+
+可以看到，第一个按钮是在**当前页面**打开必应，而第二个是在**新标签页**打开必应。如果你用的是手机，那这两种在外观上看不出很大的区别（手机版 Chrome 点击第二个按钮会表现为右上角的标签页个数+1）。但是如果你用的是电脑浏览器，那就很容易看出区别了： ![chrome-newtab-blogbing](../assets/images/chrome-newtab-blogbing.png)  
+浏览器开了一个新标签页用于访问必应，这就是我们想要的，因为 Astro 的打开行为是第一个按钮（在本页打开）。下面是这两个按钮的代码：
+
+```html title=打开必应
+<a href="https://www.bing.com">打开必应</a>
+```
+```html title=在新标签页打开必应
+<a href="https://www.bing.com" target="_blank">在新标签页打开必应</a>
+```
+
+仔细观察，会发现第二个按钮的代码多了一个 `target="_blank"。这个就是控制这个链接的打开方式，如果不写 target 就是默认为当前页面打开，**Astro 就是这样**。 [&lt;a&gt;：锚元素#target - MDN - Mozilla](https://developer.mozilla.org/zh-CN/docs/Web/HTML/Reference/Elements/a#target)
+
+**设想一下，看的教程需要我们打开一个链接操作，但是点了之后，链接就立马在本页打开，教程就被那个链接的新页面覆盖，看不到了。那这时候你要么鼠标中键开链接（快速用新标签页打开链接），要么右键开。不过，还是挺麻烦的吧。**
+
+所以我们需要：**让我们的链接通过新标签页打开，而非在当前页面打开**。
+
+当然，你自己在文章里写 `<a href="https://xxx.com" target="_blank">xxx</a>` 也是一样的效果，但谁又会有这么多时间去写这么一长串的a元素呢？
+# 使用插件 rehype-external-links
+::github{repo="rehypejs/rehype-external-links"}
+
+:::note[笔记]
+即使这个插件的官方 npm 文档 [When should I use this?](https://www.npmjs.com/package/rehype-external-links?activeTab=readme#when-should-i-use-this) 中描述的样例和我们的需求有着天壤之别，但没关系，它的功能已经包含了我们需要的东西。
+:::
+
+## 安装插件
+假如你的项目使用的包管理器是 pnpm，那就用 pnpm 的命令安装。npm 同理。
+
+```bash title="使用 pnpm 包管理器安装"
+pnpm i rehype-external-links
+```
+
+```bash title="使用 npm 包管理器安装"
+npm i rehype-external-links
+```
+
+安装成功后你的 `package.json` 中会新增一个类似于 `"rehype-external-links": "^3.0.0",` 的行：
+
+```json title=package.json ins={2} startLineNumber=50
+    "rehype-components": "^0.3.0",
+    "rehype-external-links": "^3.0.0",
+    "rehype-katex": "^7.0.1",
+```
+
+## 配置插件
+在根目录的 `astro.config.mjs` 文件内加入以下**5行**代码：
+```js title=astro.config.mjs collapse={2-105, 145-177} ins={132-137}
+import sitemap from "@astrojs/sitemap";

+			[
+				rehypeComponents,
+				{
+					components: {
+						github: GithubCardComponent,
+						note: (x, y) => AdmonitionComponent(x, y, "note"),
+						tip: (x, y) => AdmonitionComponent(x, y, "tip"),
+						important: (x, y) => AdmonitionComponent(x, y, "important"),
+						caution: (x, y) => AdmonitionComponent(x, y, "caution"),
+						warning: (x, y) => AdmonitionComponent(x, y, "warning"),
+					},
+				},
+			],
+			[
+				rehypeExternalLinks,
+				{
+				target: '_blank',
+				},
+			],
+			[
+				rehypeAutolinkHeadings,
+				{
+					behavior: "append",
+					properties: {
+						className: ["anchor"],
+					},
+					content: {
+						type: "element",
+						tagName: "span",
+						properties: {
+							className: ["anchor-icon"],
+							"data-pagefind-ignore": true,
+						},
+						children: [
+							{
+								type: "text",
+								value: "#",
+							},
+						],
+					},
+				},
+			],
+		],
+	},
+	vite: {
+		build: {
+			rollupOptions: {
+				onwarn(warning, warn) {
+					// temporarily suppress this warning
+					if (
+						warning.message.includes("is dynamically imported by") &&
+						warning.message.includes("but also statically imported by")
+					) {
+						return;
+					}
+					warn(warning);
+				},
+			},
+		},
+	},
+});
+```
+
+至此，插件的配置就完成了。随便找个**文章内链接**点击，应该会在**新标签页**打开，而非原来的在当页打开。
