Project Title: FireData: Connecting R to Google Firebase

---

FireData integrates R Datascience with the abilities and possibilities of the Google Firebase Framework.

Firebase makes it possible to exchange in real-time information in the Cloud and thereby opening the R language to IoT hardware/data processing. Other than that it is also immensely useful for shiny application to integrate Social Authentications and persistent data & uploads.

This package was created within the framework of Google Summer of Code 2017 and 2018.

Database Setup:

• visit https://firebase.google.com/
• login and enter the "console"
• add new project
• find the API keys at the "overview" page clicking on add firebase to web-app
• certain functions requires OAuth 2.0 access which needed client_id and client_secret, these can be found from the google developer console

R Package Setup:

if (!require("devtools")) install.packages("devtools")
devtools::install_github("Kohze/fireData")

library(fireData)

Authentification

• using anonymous login

token <- anonymous_login(project_api = "AIzaSyAjZLO9-CRV3gObpwdFz-k8AiTOxHSBmdc")

token$idToken

General Functions:

• uploading a data.frame:

upload(x = mtcars, projectURL = "https://firedata-b0e54.firebaseio.com/", directory = "main")

• patching a data.frame:

patch(x = mtcars, projectURL = "https://firedata-b0e54.firebaseio.com/", directory = "main/-KxwWNTVdplXFRZwGMkH")

• putting a data.frame:

put(x = mtcars, projectURL = "https://firedata-b0e54.firebaseio.com/", directory = "main/-KxwWNTVdplXFRZwGMkH")

• download a data.frame:

download(projectURL = "https://firedata-b0e54.firebaseio.com/", fileName = "main/-KxwWNTVdplXFRZwGMkH")

• register a new user

createUser(projectAPI = "AIzaSyAjZLO9-CRV3gObpwdFz-k8AiTOxHSBmdc", email = "your@email.com", password = "12341234" )

• create token for authenticated requests (can be used for the token argument of upload/download)

auth(projectAPI = "AIzaSyAjZLO9-CRV3gObpwdFz-k8AiTOxHSBmdc", email = "robin@kohze.com", password = "12341234")

• reset user password

resetPassword(projectAPI = "AIzaSyAjZLO9-CRV3gObpwdFz-k8AiTOxHSBmdc", email = "useYourOwn@email.com")

• backup the database and save as .json

dataBackup(projectURL = "https://firedata-efa5a.firebaseio.com", secretKey = "2bYA6k72wKna90MqPGa6yuMG7jAysoDJZwJqYXsm", "test.json")

fireData is already integrated into a several projects.

• SpatialMaps: A spatial proteomics platform that utilizes firebase as cross platform database.

• Cryptotrade-hq bot: A simple data collector (with shiny) that uses firebase for secure storage of API keys.

We are currently planning to add the new Cloud Firebase database and enhance the integration into R web applications.
