F8App-ReactNative项目源码分析1-初体验

近期开始研究Facebook f8app项目，目标是理解Facebook官方React Native f8app的整体技术架构，给公司目前几个的React Native项目开发提供官方经验借鉴，并对原生开发和React Native开发进行框架层面的融合。

我目前的技术情况是熟悉Android，Swift iOS，Node.js，MongoDB和JavaScript移动端开发，了解Objective C,React.js和React Native,但缺少实际开发经验，对Parse，GraphQL只是听说过。所以只能一步一步折腾了。本文将介绍f8app的实际上手经验，如何把f8app在Mac上run起来。

首先是阅读秋百万的构建 F8 App / React Native 开发指南 对项目有个整体了解。

然后到git上clone代码按说明运行起来，这一步遇到了坑，原因是官方的安装过程有错误，少了react-native start这个命令。

iOS启动后会报错，运行 react-native start就可以了

2016-05-17 11:34:12.357 [fatal][tid:main] Cannot find entry file index.ios.js in any of the roots: ["/Users/zhangxitao/work/github/f8app"]

项目依赖 Requirements

React Native (follow iOS and Android guides)

Xcode 7.3 +

CocoaPods (only for iOS)

Version 1.0+ recommended (

gem install cocoapods --pre

)

MongoDB (needed to run Parse Server locally)

修改后的安装过程

Clone the repo

$ git clone https://github.com/fbsamples/f8app.git $ cd f8app

Install dependencies (npm v3+):

$ npm install
$ (cd ios; pod install)        # only for iOS version

Make sure MongoDB is running:

先下载mongodb或直接通过

brew install mongodb

命令安装。Mongodb不熟悉的需要先学习下mongodb的常用命令，和mysql有些类似。

$ lsof -iTCP:27017 -sTCP:LISTEN
$  mongod   --dbpath  YOURDATAPATH/mongodata/ &  #启动mongodb

NOTE: if installed with Homebrew run

brew info mongo

and

check out the Caveats section.

If you prefer to use an external MongoDB server, set

DATABASE_URI

:

$ export DATABASE_URI=mongodb://example-mongo-hosting.com:1337/my-awesome-database

Start Parse/GraphQL servers:

$ npm start
$ react-native start

Import sample data (the local Parse Server should be running): 并验证一下数据是否导入正确。

$ npm run import-data
$ mongo
MongoDB shell version: 2.6.5

#会查到很多数据

Make sure everything works by visiting:

Parse Dashboard: http://localhost:8080/dashboard

Graph*i*QL: http://localhost:8080/graphql

Running on Android:

$ react-native run-android
$ adb reverse tcp:8081 tcp:8081   # required to ensure the Android app can
$ adb reverse tcp:8080 tcp:8080   # access the Packager and GraphQL server

Running on iOS:

$ react-native run-ios

实际运行效果

这样安卓和iOS模拟器应该都跑起来了。实际效果如下：
