[react.js] 初學筆記

記錄一下react.js學習上要懂的ecosystem，
做一下自已要速查的note

npm套件管理工具

node.js用來裝需求的套件的工具，安裝完的套件可以給node.js後端用或透過webpack ES6方法來載入套件

webpack build tool (可以用Gulp+browserify)

因為早期都用gulp，但webpack出到v3了，這次就換試webpack這個工具

[react.js] 雷雷小伙伴之坑

記錄一下菜B巴react.js之旅的error

Warning: Invalid DOM property `class`. Did you mean `className`?

就是JSX裡面用了html的保留字class啦，要用className

Uncaught Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function but got: object

//死亡的原因是import加了{}

// import { App}  from './components/App';

import  App  from './components/App';

[node.js] 如何切換development與production模式

有關node.js處理NODE_ENV來切換developer/production的方法種類

export NODE_ENV=production

Or if you are in windows you could try this:

SET NODE_ENV=production

or you can run your app like this:

NODE_ENV=production node app.js

You can also set it in your js file:

process.env.NODE_ENV = 'production';
