-# Create a CMS-Powered Blog Using Vue.js
+恭喜你已经发布了你的 Vue.js 网站！现在你想要在网站上快速加入一个博客，但不想新起一台服务器去部署一个 WordPress 实例 (或任何基于数据库的 CMS)。你希望只添加一些 Vue.js 的博客组件和一些路由就能搞定对吧？你想要的就是直接消费你的 Vue.js 应用中 API 来完全支撑起一个博客站。这份教程将会告诉你如何做到这一点，所以让我们来看看吧！
 
-So you've just launched your Vue.js website, congrats! Now you want to add a blog that quickly plugs into your website and you don't want to have to spin up a whole server just to host a Wordpress instance (or any DB-powered CMS for that matter). You want to just be able to add a few Vue.js blog components and some routes and have it all just work, right? What you're looking for a blog that's powered entirely by API's you can consume directly from your Vue.js application. This tutorial will teach you how to do just that, let's dive in!
+我们将会使用 Vue.js 快速构建一个基于 CMS 的博客站。它使用了 [ButterCMS](https://buttercms.com/)，一个 API 优先的 CMS，让你使用 ButterCMS 仪表盘管理内容并将我们的内容 API 集成到你的 Vue.js 应用。你可以为一个新的项目或在一个已有的 Vue.js 项目使用 ButterCMS。
 
-We're going to quickly build a CMS-powered blog with Vue.js. It uses [ButterCMS](https://buttercms.com/), an API-first CMS that lets you manage content using the ButterCMS dashboard and integrate our content API into your Vue.js app. You can use ButterCMS for new or existing Vue.js projects.

 })
 ```
 
-This API request fetches your blog posts. Your account comes with one example post which you'll see in the response.
+这个 API 请求会获取你的博客文章列表。你将会在请求的响应中看到你的账户的一篇示例博文。
 
-## Display posts
-To display posts we create a `/blog` route (using vue-router) in our app and fetch blog posts from the Butter API, as well as a `/blog/:slug` route to handle individual posts.
+## 展示博文
 
-See the ButterCMS [API reference](https://buttercms.com/docs/api/?javascript#blog-posts) for additional options such as filtering by category or author. The response also includes some metadata we'll use for pagination.
+为了展示博文，我们在应用中创建了一个 `/blog` 路由 (使用 Vue Router) 并从 Butter API 获取博文列表，同样的还创建了一个 `/blog/:slug` 路由来处理单篇博文。

-Now our app is pulling all blog posts and we can navigate to individual posts. However, our next/previous post buttons are not working.
+需要注意的一点是在通过参数控制路由时，比如当用户从 `/blog/foo` 导航至 `/blog/bar` 时，我们复用了相同的组件实例。因为这两个路由渲染了相同的组件，所以比销毁老实例再创建新实例的效率更高。
 
-One thing to note when using routes with params is that when the user navigates from /blog/foo to /blog/bar, the same component instance will be reused. Since both routes render the same component, this is more efficient than destroying the old instance and then creating a new one.
+<p class="tip">注意，用这种方式使用组件意味着这个组件的生命周期钩子将不会被调用。请移步 Vue Router 的文档了解[动态路由匹配](https://router.vuejs.org/en/essentials/dynamic-matching.html)。</p>
 
-<p class="tip">Be aware, that using the component this way will mean that the lifecycle hooks of the component will not be called. Visit the Vue.js docs to learn more about [Dynamic Route Matching](https://router.vuejs.org/en/essentials/dynamic-matching.html)</p>
+为了解决这个问题，我们需要匹配 `$route` 对象并在路由发生变化的时候调用 `getPost()`。

-## Alternative Patterns
-
-An alternative pattern to consider, especially if you prefer writing only in Markdown, is using something like [Nuxtent](https://nuxtent.now.sh/guide/writing#async-components). Nuxtent allows you to use `Vue Component` inside of Markdown files. This approach would be akin to a static site approach (i.e. Jekyll) where you compose your blog posts in Markdown files. Nuxtent adds a nice integration between Vue.js and Markdown allowing you to live in a 100% Vue.js world.
-
+## 替代方案
 
-## Wrap up
+有一个替代方案，尤其在你只喜欢写 Markdown 时适用，就是使用诸如 [Nuxtent](https://nuxtent.now.sh/guide/writing#async-components) 的工具。Nuxtent 允许你在 Markdown 文件内部使用 `Vue Component`。它类似一个静态站点工具 (例如 Jekyll)，让你在 Markdown 文件中撰写你的博文。Nuxtent 将 Vue.js 和 Markdown 很好地集成了起来，让你完全生活在 Vue.js 的世界里。
 
-That's it! You now have a fully functional CMS-powered blog running in your app.  We hope this tutorial was helpful and made your development experience with Vue.js even more enjoyable :)
+## 总结
 
+差不多就是这些了！现在你已经在自己的应用中拥有了一个可以正常工作的 CMS 博客。我们希望这份教程可以帮助你，使你的 Vue.js 开发体验更有乐趣 :)
