使用 Photon 的 R 闪亮独立应用程序

Question

我正在寻找一种简单的方法来从闪亮的应用程序创建独立的应用程序。我第一次看到凯蒂的“闪亮遇见电子”演讲（参见谷歌）。浏览他们的网站后，我认为 Photon 是他们最新的方法！

我尝试以最简单的方式测试 Photon 但没有成功。

To test Photon, I did the following:

1. install node.js (works, tested 'npm' in CMD line, recognised)

2. install git (works, tested 'git' in CMD line, recognised)

3. install Photon using your instructions

4. Open new basic shinyApplications: RStudio > File > New file > Shiny Web App... >>
--> Name 'PhotonTestApp'
--> multiple fFIle (ui.R/server.R)
--> C:/ShinyApps
Tested to see the app works, the basic Geyser data app.

5. setwd("C:\ShinyApps\PhotonTestApp\")

6. Launch Photon app builder
--> Shiny App Directory: C:/ShinyApps/temp
--> left default NULL in all three package inputs
--> Build

我收到以下错误：

> photon:::photon_rstudioaddin()
Listening on http://127.0.0.1:3898

Running Photon
Warning in normalizePath(path.expand(path), winslash, mustWork) :

我看到创建了一个目录： C:\ShinyApps\temp\electron-quick-start\ ，其中包含一个隐藏的 .git 目录，该目录为空。

一些附加信息：

Answer 1

打开 git cmd 将目录更改为 app.r 文件夹

然后运行以下命令： git clone https://github.com/ColumbusCollaboratory/electron-quick-start

之后从 rstudio 启动 photon 应用程序构建器并选择 app.r 的目录，该目录现在也应该有“电子快速启动”目录
