  运行 npm start build 的时候报错 Cannot find type definition file for 'chai'
  添加依赖 就好了。

"@types/chai": "^3.4.34"

这个不知道 是不是我这边的问题。

When I tried to execute the command below:

npm i -g ts-node && ts-node example/switchMap.ts

to see the execution result of switchMap, I had this error:

Error: Cannot find module 'typescript'

Is there something I missed to install?

升级版本之后webpack配置也要修改

我checkout了master分支，npm install ,然后checkout seed分支，又执行了npm install ，npm start 还是提示有些module没有，试图安装了几个，还是有问题。麻烦你看一下是不是把所有的依赖都写进去了。或者，update一下readme

RROR in /Users/**/learning-rxjs/tsconfig.json
error TS2688: Cannot find type definition file for 'node'.

切换成 seed 分支无法运行, master 分支是可以的

解决办法：
package.json
"typescript": "^2.3.4",
改为"typescript": "2.3.4",
重新install

I have a question in the codes below which generates the stream of the click on the items. What .filter(e => e.target === $todoItem) is for?

When I commented that line, the toggle works too.

const toggle$ = item$.mergeMap($todoItem => {
  return Observable.fromEvent<MouseEvent>($todoItem, 'click')
    // Can I comment this line? 
    // .filter(e => e.target === $todoItem)
    .mapTo($todoItem)
})
  .do(($todoItem: HTMLElement) => {
    if ($todoItem.classList.contains('done')) {
      $todoItem.classList.remove('done')
    } else {
      $todoItem.classList.add('done')
    }
  })

The same question in the codes of generating the stream of add.

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because we are using your CI build statuses to figure out when to notify you about breaking changes.

Since we did not receive a CI status on the greenkeeper/initial branch, we assume that you still need to configure it.

If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with greenkeeper/.

We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

这个API 是不是有问题，const apiHost = 'http://127.0.0.1:5000/api' ，反正是报错的，是我打开的方式不对，还是要添加什么？

win10
npm 3.8.9
node v6.2.0
我切换分支后，再npm start报错，要怎么解决？

================
还有个小白问题，刚接触TypeScript和RxJS，不是很熟悉。
按官网的npm install rxjs-es安装后，自己编了hello.ts文件,内容如下：
import Rx from 'rxjs/Rx';

Rx.Observable.of(1,2,3)
.map(x => console.log(x));

tsc hello.ts编译之后生成hello.js，放在html的<script>里测试显示找不到这个依赖

Uncaught ReferenceError: require is not defined
at greeter.js:2

这个要怎么解决，是要在特定目录下写ts文件吗？
