hx744 load cell weight node red

Hi everyone. I'm still a beginner and I'm preparing a program that displays the current weight on node red using a load cell and hx711 and raspberry pi3. I have the python program that calculates the weight it works well but when I try to associate this with node red I'm completely blocked since I would like to take the result generated by my python program and display it on nod red directly. I looked in the node red palette if an hx711 library do exist but i found nothing then Ive decided to build my own node red hx711 node I found that i have to assemble three types of files : html js and jason to do this. I found these three files well prepared by someone but I'm stuck there I don't know how to do that

am i thinking right ? can anybody tell me how to do that just by using raspberry ?
