Thinking about encryption and performance, I think it is. But it will take a long time to spread.

But there're some bugs, see https://github.com/philipwalton/flexbugs

I think it is necessary sometimes. E.g, in componentDidMount() .

I created a demo( v2ex-preact ) with preact/redux/react-router/react-redux/react-router-redux . It works fine mostly, but I found a bug that the author promised to fix. I suggest you using preact-compat to make preact acting as react , in case you encounter some issues that matter to your application, you can switch to react quickly.

We use echarts , http://echarts.baidu.com/ , in Chinese.

My option is, "rem" and "em" are both unsafe for layout because of rounding to "px". I reject it.

Thanks. Dependency-tree IS in the memory, but that costs very little. The key is, every node transforms files(called Stream in panto.js ) holds a copy of file content, that may takes a lot of memory. My solution is, if the size of content exceed 1Mb, save it to tmp file. I'm thinking about convert strings to buffer in the near future. And the stream idea is great, like gulp does, but I need to merge multiple processes into one. I'm considering how to implement that.

tree-shaking is the key, Webpack is good at "Single Page App", you can use rollup more flexibly

Agree, but fetch requires Promise , what is the best Promise polyfill ?
