itkwidgets for javascript

[Tinanuaa]

Hi,
I am trying to use itkwidgets in my react app, I found the itkwidgets package here https://npm.io/package/itkwidgets. After I install itkwidgets in my react app, I can import the viewer etc in a js file, the js file is like below

import {
   ViewerModel,
   ViewerView,
   LineProfilerModel,
   LineProfilerView 
 } from "itkwidgets";

 import {
   Grid 
 } from "@mui/material";
export const LiveViewer=()=>{
   return (<Grid></Grid>)
}

Then, I import LiveViewer in another tsx file and use the LiveViewer component defined above,

import React, { useEffect, useState, useRef, useMemo } from "react";
// import { useStyles } from "./Monitoring.styles";
import { useTheme } from "@mui/material/styles";
import {
  Box,
  Typography,
  Grid,
  Snackbar,
  Alert,
  avatarClasses,
  Stack,
  Button,
} from "@mui/material";

import {LiveViewer} from "./LiveViewer";
 

const Monitoring = () => {
 

  return (
    <Box sx={{ width: "100%", height: "100%" }}>
 
      <Grid>
 
        <LiveViewer/>
      </Grid>
    </Box>
  );
};
export default Monitoring;

I got the following errors, is itkwidgets compatible with typescript?

Let me suggest using the JavaScript project that backs itkwidgets: https://github.com/Kitware/itk-vtk-viewer

And see PR Kitware/itk-vtk-viewer#485 for how to bundle the viewer into your project.

Also, if you are looking for a javascript medical image viewer to integrate into a new app, you may also want to look at VolView: Try it: https://volview.netlify.app/ See the open-source code: https://github.com/Kitware/VolView s

Hi Paul, thanks for the recommendation, but the errors I had above are all related to itk-vtk-viewer and the PR doesn't seem to relate to the errors above.

[PaulHax]

Your right, the errors are from itk-vtk-viewer. Seems your setup is trying to build itk-vtk-viewer directly. You should not need to. I dont think the itkwidget npm package is maintained.

If you want to use the viewer in your project, follow the pattern in Kitware/itk-vtk-viewer#485

Or pull the pre-build itkVtkViewer.js bundle from the CDN, like this project: https://github.com/InsightSoftwareConsortium/itk-viewer-bootstrap-ui/blob/main/index.html

Hi PaulHax, I tried to play with itk-vtk-viewer, I'm using create-react-app typescript template as a start, and I followed this link(https://kitware.github.io/itk-vtk-viewer/docs/embeddedViewer.html), I can display the image like this

but I can't see a histogram like this

Is there an example for react-app so I can try to set up a live viewer with histogram just like what itkwidgets has?(https://hub.ovh2.mybinder.org/user/insightsoftware-tium-itkwidgets-ip6sy2yi/doc/tree/examples/Hello3DWorld.ipynb)

I tried to follow Kitware/itk-vtk-viewer#485 to set up itk-vtk-viewer in the create-react-app typescript template, I can set the publicPath to '', but I can't find the pipeline.worker.js and I don't know how I can lift it. I'm using craco to change the config for the create-react-app app. And after I changed the publicPath, I still can't import itk-vtk-viewer, the error is

Failed to parse source map from '/workspaces/itk-vtk-viewer-pg/my-app-ts-itk-vtk-viewer/node_modules/itk-vtk-viewer/dist/itkVtkViewer.js.map' file: Error: ENOENT: no such file or directory, open '/workspaces/itk-vtk-viewer-pg/my-app-ts-itk-vtk-viewer/node_modules/itk-vtk-viewer/dist/itkVtkViewer.js.map'
