Update: README.md RESTful API

This is a big commit, some font-end function are still working,
including manage, error handle, as others.

 # MSW Open Music Project
 
-## 简介
+## Introduction
 
-Fork from `msw-file`，目前是一个音乐播放器。
+A light weight personal music streaming platform.
 
 ![demo1](demo1.jpg)
 
 [toc]
 
-## 编译 & 构建
+## How to build
 
-### 编译后端
+### Build the back-end server
 
-`go build`
+`make linux` or `make windows`
 
-如无任何输出，说明构建成功，可执行程序位于 `msw-open-music`
+The executable file is named `msw-open-music` or `msw-open-music.exe`
 
-### 构建前端
+### Build the font-end web pages
 
-`make`
+To build production web page `make web`
 
-说明：`Makefile` 脚本中的代码会在 `dist` 目录生成用于生产环境的前端 web 文件。这个脚本做的事情是简单地将 `vue` `vue-router` 等 js 文件替换成生产版本。并使用 `minify` 工具处理 `css` 和 `html` 文件。
+This command will go into `web` directory and install `node_modules`. Then execute `npm run build` command. The built web pages is under `web/build` directory.
 
-## 使用
+To start the development, run `cd web` and `npm start`
 
-### 后端使用
+## Usage
 
-初次使用请配置 `config.json`， **最重要的是配置 `token`** 。
+Start back-end server. Server will listen on 8080 port.
 
-默认 ffmpeg 线程 `ffmpeg_threads` 为 1 ，大于 1 以上的值似乎对编码音频没有效果。
+Build the font-end web page, then go to <http://127.0.0.1:8080>
 
-#### config.json 说明
+By default:
 
-- `database_name` 字符串类型，指定 sqlite3 单文件数据库的位置，如果不存在则会自动创建。
+- URL matched `/api/*` will process by back-end server.
-- `addr` api 服务监听端口，该参数会被传入 `http.Serve.Addr`
+- Others URL matched `/*` will be served files under `web/build/`
-- `token` 字符串，作为管理密码
-- `ffmpeg_configs`，字典，其键是 ffmpeg 配置的名称，其值是放入 `ffmpeg -i input.mp3 -vn [此处] -f matroska -` 的参数，类型是字符串。 **注意：** 前端会按键名来排序配置列表，并以列表中的第一项作为默认配置。
-- `file_life_time` 临时文件生存时间，超过该时间没有访问该临时文件，tmpfs 将删除此文件。
-- `cleaner_internal` 清理器的检查间隔。
-- `root` 存放该临时文件目录， **Windows 用户请替换成合适的目录。**
 
-### 前端使用
+### Run back-end server
 
-前端文件引用均使用相对路径，将前端文件放到同一目录下即可。
+Configuration file is  `config.json`， **Please modify your `token`** 。
 
-前端在调用后端 api 时使用的是绝对路径，例如 `/api/v1/hello`。如需更改，可以修改后端 `api.go` 中的 `apiMux` 和 `mux` 的相关属性。
+Default `ffmpeg_threads` is 1. Seems value larger than 1 will not increase the audio encode speed.
 
-## 关于临时文件夹的说明
+#### config.json description
 
-前端播放器中勾选了 `Prepare` ，后端将转码文件到临时文件夹，然后直链提供文件。这有助于修复网路不稳定时 TCP 链接断开，stream 模式下 ffmpeg 中断输出并且不能断点续传的问题。
+- `database_name` string type. The filename of `sqlite3` database. Will create if that file doesn't exist.
+- `addr` string type. The listen address and port.
+- `token` string type. Password.
+- `ffmpeg_config_list` list type, include `ffmpegConfig` object.
+- `file_life_time` integer type (second). Life time for temporary file. If the temporary file is not accessed for more than this time, back-end server will delete this file.
+- `cleaner_internal` integer type (second). Interval for `tmpfs` checking temporary file.
+- `root` string type. Directory to store temporary files. Default is `/tmp`, **please modify this directory if you are using Windows.**
 
-临时文件夹管理器位于 `internal/pkg/tmpfs` 中，默认删除时间是 10 分钟。10分钟内如果没有对该临时文件的访问，则会删除此临时文件。
+### Run font-end web page
+
+Open your web browser to <http://127.0.0.1:8080> you will see the web pages.
+
+## About tmpfs
+
+If the `Prepare` mode is enabled in the font-wed player, back-end server will convert the whole file into the temporary folder, then serve file using native method. This can avoid ffmpeg pipe break problem cause by unstable network connection while streaming audio.
+
+The default temporary folder is `/tmp`, which is a `tmpfs` file system in Linux operating system. Default life time for temporary files is 600 seconds (10 minutes). If the temporary file is not accessed for more than this time, back-end server will delete this file.
 
 ## Change log
 
-- `v1.0.0` 首个版本
+- `v1.0.0` First version. Ready to use in production environment.
+- `v1.1.0` Use `React` to rewrite the font-end web pages (Previous using `Vue`).
 
-## 后端 API 文档
+## Back-end API references
 
-说明中带有 `stream` 或 `流` 相关字样的，说明该 API 以 `io.Copy` 方式传输文件，不支持断点续传
+API named `stream` means it transfer data using `io.Copy`, which **DO NOT** support continue getting a partially-downloaded audio.
 
-无需返回数据的 API 将返回 OK，某些 API 可能会在 `status` 字段中返回详细的执行信息。
+API does not need to respond any data will return the following JSON object.

+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
+
+The page will reload if you make edits.\
+You will also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
+
+If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
+
+You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
+
