Session app - upload data from a external csv file

[Anonymous]

Hi all,

Need help for the following things.

1) Can we upload data from a external file (csv,xls etc) into a session app ?

2) Can we call the Qlik API methods on session app object? example sessionapp.getFieldList(); ?

3) Script : The demos available online by Qlik just demonstrates a simple dynamic LOAD script.Is there a way using which we can Load data using inline load method or any other method?

Hi,

We have a helper library for loading data in you sessionApp GitHub - qlik-oss/halyard.js: JavaScript library for generating Qlik Load Scripts using an abstracte...

1) yes for ex. with halyard,js

2) yes, the only difference between app and sessionApp it's if it is persisted - all API's are the same

3) (if I understood well) yes haylard.js or setScript method ‒ Qlik Sense Developers

I hope this helps

Hi aaz‌,

Thanks for your reply!

I tried using halyard.js, it is good.But, I am new to node.js and the library requires node.js to run/create load scripts on the fly.Node js runs using a command prompt.Do i need to open a command prompt each time to run the application?(Might be a silly question new to node.js). From the end user perspective, how would the app function like a web app without need to run the node commands ?

Thanks for your help !

Hi,

You need to run halyard.js from the browser. Unfortunately we haven't any examples of how this is done with halyard.js. But we have this enigma.js example https://github.com/qlik-oss/enigma.js/tree/master/examples/complete/car-models that creates a session app with data from a CSV file and visualize it using d3.

I hope this helps

hi Stefan,

Thanks for your help !I am facing issue understanding the flow of the code as it uses node and other dependencies.

I need to achieve the connection to Qlik engine(to create new connection to upload data from external file like csv, create apps/vizualizations on the fly) etc. using a wizard like functionality in a browser. Using node.js for this particular app is cumbersome.

Can you please help me with a simple example to use enigma.js in a browser?The main problem that i am facing is upload data from external file (absolute/relative) path without enabling "Legacy Mode". Halyard.js is a great library with cool mixins but it again uses node.

Some insight about this would help

Thanks,

Abhishek
