(regl) Error compiling fragment shader

Hello everyone,
I'have a problem on my angular 5 project.
I try to use this chart : Polar Chart, but i have an error.

Plotly.js version : 1.35.2
Errors :

file number 0: webpack-internal:///../../../../plotly.js/node_modules/regl-scatter2d/scatter.js:188:21
1| ./marker-frag.glsl | ^^^ | syntax error

I use the framwork correctly with good data.
I checked this issue : #2258 but i'm not sure if my problem is link to this.

Thank's you !

How are you building your bundle?

See #2502 for a similar report.

I installed the latest version of plotly from npm website.
i import plotly like this : import * as Plotly from 'plotly.js';

Then i init my chart exactly like this : https://codepen.io/plotly/pen/wypMvM

i just replace "plot" by "newPlot" in the last line : Plotly.plot('myDiv', data, layout);
by Plotly.newPlot(this.chart1.nativeElement, data, layout);

I have this result :

I don't think your problem is caused by your JS script. It is caused by how you're building plotly.js (with webpack I presume).

Yeah you right, i found my problem:
I did not import this line in my tsconfig.json

"compilerOptions": {
    "paths": {
        "plotly.js": [
            "../node_modules/plotly.js/lib/core.js"
        ]
    }
}

Related to this issue : #2260

I have no errors right now but i can't see bubbles like the example on the website :

@vador31

@vador31 you make it very hard to help you.

Can you paste the full webpack config you're using? While at it, can you paste the JS code you're using as well? Looks like the screenshot from #2560 (comment) uses scatterpolar whereas your latest #2560 (comment) uses a legacy r/t scatter trace.

@etpinard

@etpinard yeah sorry, it's because i don't really know where i need to watch to resolve my problem.

I checked this commit which resume my problem.
If I understand correctly, to use scatterpolar ,I have to make an eject of the project in order to retrieve the webpack.config.
Then i need to add a loader to use GLSL plots.
Is that correct ??

I haven't modify my webpack.config.js file.

Then i need to add a loader to use GLSL plots.
Is that correct ??

YES. See -> https://github.com/plotly/plotly.js#building-plotlyjs-with-webpack

Problem solved !! 👍 Thank's you very very very much !! 😄
