Implementation of fabric.js in react

I am trying to implement fabric.js in react. I have js code of drawing line using fabric.js and I want to convert it into react code. can anyone help me here is my js code. It is running fine in pure js but not react.;

         let canvas = new fabric.Canvas("canvas", {
             width: 600,
             height: 400,
             backgroundColor: "#808080"
            });
        
        let lineBtn = document.getElementById("adding-line");
        let newLineCoor = {};
        let line;
        let isMouseDown = false;
        let addingLineBtnClicked = false;
        
        const activateAddingLine = () => {
          if (addingLineBtnClicked === false) {
            addingLineBtnClicked = true;
            canvas.on("mouse:down", startAddingLine);
            canvas.on("mouse:move", startDrawingLine);
            canvas.on("mouse:up", stopDrawingLine);
            canvas.selection = false;
            // canvas.defaultCursor = "auto";
            canvas.hoverCursor = "auto";
            canvas.getObjects().forEach((element) => {
              if (element.id === "added-line") {
                element.set({
                  selectable: false
                });
              }
            });
          }
        };
        
        lineBtn.addEventListener("click", activateAddingLine);
        
        const startAddingLine = (o) => {

          });
          canvas.add(line);
          canvas.requestRenderAll();

Problem in react implementation that I am maintain state of each variables but I cant draw on canvas

It is working now. But need improvement
