push data to firebase

[mathias]

Hello,

Has anyone worked with firebase yet? (www.firebase.com)

I need to push data from an automated SAS egp to firebase.

This will allow me to request it easily from a web app and set user permissions on it.

https://www.firebase.com/docs/rest/guide/saving-data.html

Beause it's still new, I cannot find a single article/post/question about this.

Many thanks,

EDIT: I have SAS 9.3 and I'm working in Enterprise Guide 5.1 on Windows7

I have no experience with this. But since firebase supports a REST Interface you might be able to use Proc HTTP

Mathias,

I would look into the following two Procedures in SAS 9.4

 - Proc JSON: To convert your SAS tables into JSON format

 - Proc HTTP: To connect to your Firebase database via Rest

Good luck,

Ahmed

I forgot to say that I'm working on SAS 9.3 and with Enterprise guide 5.1

I don't think I have proc json, but I already have created the json file with a data step.

It worked!

I'll post the code here when I'm back at work Tuesday.

This is working for me:

%let firebaseURL = https://YOURFIREBASEAPP.firebaseio.com/;
%let filePath = \\FILESERVER\BLA\BLA\BLA\;
%let jsonFile = MYDATA.json;

filename resp TEMP;
filename headout TEMP;
filename input "&filePath.&jsonFile";

proc http 
	method="PUT"
	url="&firebaseURL.&jsonFile"
	in=input
	out=resp
	headerout=headout
;run;

(POST is also working but adds a random id to your data.)

I created a JAVA adapter for Firebase.  Check it out!

https://github.com/FriedEgg/firebase4sas

filename fbase "/path/to/firebase-client-jvm-2.3.1.jar"; /*https://cdn.firebase.com/java/firebase-client-android-2.3.1.jar*/
filename fb4sas "/path/to/firebase4sas.jar"; /*https://github.com/FriedEgg/firebase4sas/releases*/

/* create a file reference for the classes we are going to compile below with PROC GROOVY*/
filename cp temp;
proc groovy classpath=cp;

   /* add the two dependent libraries*/
   add classpath=fbase;
   add classpath=fb4sas;

   /* create a Model for the objects we are going to load. */
   submit load;
      public class Person {
         private String sex;
         private double age;
         private double height;
         private double weight;

         public Person(String sex, double age, double height, double weight) {
            this.sex    = sex;
            this.age    = age;
            this.height = height;
            this.weight = weight;
         }

         public String getSex() {
            return sex;
         }

         public double getAge() {
            return age;
         }

         public double getHeight() {
            return height;
         }

         public double getWeight() {
            return weight;
         }

         public String toString() {
            return "Person: Sex=" + sex + ", Age=" + age + ", Height" + height + ", Weight" + weight;
         }
      }
   endsubmit;

   /* create a class from the abstract to perform the load of our model */
   submit load;
      import java.lang.InterruptedException;

      public class PersonLoader extends AbstractFirebase4Sas {
         public PersonLoader(String firebase, String dsn, String name, String sex, double age, double height, double weight) {
            setFirebase(firebase);

            Person p = new Person(sex, age, height, weight);
            setLoaderObject(p);

            addChild(dsn);
            addChild(name);

            try {
               loadObject();
            } catch (InterruptedException e) {
               e.printStackTrace();
            }
         }
      }
   endsubmit;

   /* you can test it in PROC GROOVY */
   /*
   submit;
      lp = new LoadPerson("MYFIREBASE", "class", "Frog", "F", 14.1, 15.1, 16.1);
   endsubmit;
   */

quit;

/* add compiled classes from PROC GROOVY to session CLASSPATH */
options set=classpath "%sysfunc(pathname(cp,f))";

/* use data step JavaObject Component to load our data set to Firebase */
data _null_;
   set sashelp.class indsname=dsn;

   declare javaObj lp;
   lp = _new_ javaObj ("LoadPerson","MYFIREBASE",scan(dsn,2,'.'),name,sex,age,height,weight);

   lp.flushJavaOutput();
   lp.delete();

run;

You can create you own model and loader classes simply enough to load any table.  It should work with SAS 9.3+

I've made a macro that takes a sas dataset and writes it to firebase with parametrable variable names

https://gist.github.com/mathiasleroy/f22face83d696b45c17a

%macro pushFirebase(dataset,firebaseName,fbObject,variables);
/*
	! change temporaryFilePath to fit your environement

	dataset 	= sas data set to push to firebase
	firebaseName= name of your firebase app name (xxx.firebaseio.com)
	fbObject  	= name of the firebase object to create
	variables 	= list of variables to include, separated by dashes -
*/


	/* CONSTANTS */
	%let temporaryFilePath = \\sas9xbi\Data2\tmp\;

	/* VARIABLES */
	%let firebaseURL = https://&firebaseName..firebaseio.com/;
	%let fileName = &fbObject..json;
	%let variablesLength =  %sysfunc(count(&variables,-));

	
	/********************************************************************
		CREATE JSON OBJECT
	********************************************************************/

	data _null_;
		set &dataset nobs=nobs end=end;
		file "&temporaryFilePath.&fileName";

		if _n_=1 then put '{';
		
			put '"' %scan(&variables,1,-) +(-1) '":{';

				%do i = 1 %to &variablesLength+1;
					variable = %sysfunc(strip("%scan(&variables,&i,-)"));
					*this is a repetition, but it makes json cleaner;
					if (&i ne 1) then put ',"' variable +(-1) '":' %scan(&variables,&i,-) ;
					else put '"' variable +(-1) '":' %scan(&variables,&i,-) ;
				%end;
			put '}';

			if not end then do;
				put ',';
				end;

		if end then do;

			end;
		run;
