Here are the highlights:
- [Rich Harris](https://twitter.com/rich_harris) took us through a tour of Svelte's history and announced [his move to Vercel](https://vercel.com/blog/vercel-welcomes-rich-harris-creator-of-svelte) - where he will be helping maintain Svelte full-time!

CSS is a core part of any web app. By extension, a UI framework that doesn't have a built-in way to add styles to your components is unfinished.

# Rollup - 下一代 ES6 模块化打包工具 - 对 Rich Harris 的采访

鉴于浏览器目前尚不能按照“原样”解析 JavaScript 源码，所以**打包**这一步必不可少。将源代码编译成浏览器可以理解的形式，这是打包工具（例如 Browserify，Rollup 或者 webpack）存在的原因。

为了深入探讨这个话题，我们正在采访 Rollup 的作者  [Rich Harris](https://twitter.com/Rich_Harris)。

> 我早些时候已经采访过 [Rich，他同样是 UI 框架 Svelte 的作者](https://survivejs.com/blog/svelte-interview/)。

## 你可以介绍下自己吗？

Earlier this month, I had the privilege of appearing on [The Changelog](https://changelog.com/podcast), a podcast about software development. We had a fun (for me) and wide-ranging conversation:

* life as a coder inside a newsroom
* the big compilers-as-frameworks trend
* scalability

* svelte-vscode
* associating .svelte files with HTML in VSCode, Sublime, etc.
