I try to run MapBox under Blazor , using the next library
https://api.tiles.mapbox.com/mapbox-gl-js/v1.5.0/mapbox-gl.js
When I delete the line (from default app)
<script src="_framework/blazor.server.js"></script>
MapBox library works , except events. When i restore that line then events works, but the map disappear
How to fix the problem?

index.razor:

Did so:

#inject IJSRuntime JSRuntime;
<div id='map'></div>
#code {
protected override void OnAfterRender(bool firstRender)
{
JSRuntime.InvokeVoidAsync("mapBoxFunctions.initMapBox");
}
}
P.S. I noticed that despite the fact that the site seems to work fine, but in the console you can see an error at startup
Can't anybody say how to fix the problem.
After publishing the application - no error is visible in the browser

I am trying to use import in the script I loaded in HTML, but the error occurs:
Uncaught ReferenceError: require is not defined.
I am trying to order my code with classes in typescript. Does that mean everything I write for the renderer process in vscode extensions has to be in one js file?
New to extension programming, any help appreciated.
Here is how I build HTML:
webviewPanel.webview.html = getHtmlTemplate(webviewPanel, this.context);
and my HTML looks like:
export function getHtmlTemplate(webviewPanel: vscode.WebviewPanel, context: vscode.ExtensionContext) : string {
const scriptUri = webviewPanel.webview.asWebviewUri(vscode.Uri.joinPath(
context.extensionUri, 'out', 'main.js'));
const styleResetUri = webviewPanel.webview.asWebviewUri(vscode.Uri.joinPath(
context.extensionUri, 'media', 'reset.css'));
const styleVSCodeUri = webviewPanel.webview.asWebviewUri(vscode.Uri.joinPath(
context.extensionUri, 'media', 'vscode.css'));
const styleMainUri = webviewPanel.webview.asWebviewUri(vscode.Uri.joinPath(
context.extensionUri, 'media', 'style.css'));
// Use a nonce to whitelist which scripts can be run
const nonce = getNonce();
return `

I am writing main.ts which will be compile into main.js, and I would like to use import in main.ts
I have been using the chalkboard plugin for a reveal presentation. As it is written on the github page (https://github.com/rajgoel/reveal.js-plugins/tree/master/chalkboard), I saved the drawings in a json file by pressing d (as far as I can tell, the data was correctly stored in the json file) and then I added the line src: "prova/cb.json", to the initialization for chalkboard and loaded the presentation with ?print-pdf.
However, when I open the presentation, there is no trace of the drawings that should be loaded.
This is the html of a minimal (non) working example...
Does anyone know what's going on?

I'm trying to follow the instructions here: https://docs.mapbox.com/mapbox-gl-js/example/simple-map/
My code is as follows, just as in the example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Display a map</title>
<meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no" />
<script src="https://api.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.js"></script>
<link href="https://api.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.css" rel="stylesheet" />
<style>
body { margin: 0; padding: 0; }
#map { position: absolute; top: 0; bottom: 0; width: 100%;}
</style>
</head>
<body>
<div id="map"></div>
<script>
mapboxgl.accessToken = 'MY_TOKEN';
var map = new mapboxgl.Map({
container: 'map', // container id
style: 'mapbox://styles/ericgithinji/ckfchv1sr0u581amw703zg3jh',//it also fails when I use one of the public styles
center: [-74.5, 40], // starting position [lng, lat]
zoom: 9 // starting zoom
});
</script>
</body>
</html>
The div for the map doesn't display anyting, i.e. I get a blank web page. I've followed the tests here for style_id, tileset id, and access token and they all work: https://docs.mapbox.com/help/troubleshooting/blank-tiles/
I have no idea what could be the problem. If it helps,my Index.html is hosted locally on Ubuntu Apache2 server.
I was making two mistakes: 1 - using my secret token instead of my public token and 2 - not generating a style for myself first (it didn't work with the default style from the example).
I am using Mapbox API to create simple maps and learn. I have written a very simple code to display the centre on some coordinates but the map won't show.

What am I doing wrong here?
You're using the wrong parameters for L.mapbox.map, the first element is correct, that's for the ID of a HTML element or a reference to an HTML element. The second however, isn't for the options object. The second is for your mapbox mapid (or url, or tilejson), which you get when you create your own map via the Mapbox editor: https://www.mapbox.com/editor/#app The third parameter is for the options object.
L.mapbox.accessToken = 'pk.eyJ1IjoicGF1bC12ZXJob2V2ZW4iLCJhIjoiZ1BtMWhPSSJ9.wQGnLyl1DiuIQuS0U_PtiQ';
var map = L.mapbox.map('map', 'examples.map-i86nkdio', {
center: [28.611690, 77.191008],
zoom: 13
});
I updated leaflet elevation example gpx just changing the gox name, working locally on win 7 or OS X and Safari or Chrome. Nothing shows up.
var map = new L.Map('map');
var url = 'http://otile{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.jpeg',
attr ='Tiles Courtesy of MapQuest — Map data © OpenStreetMap contributors, CC-BY-SA',
service = new L.TileLayer(url, {subdomains:"1234",attribution: attr});
var el = L.control.elevation();
el.addTo(map);
var g=new L.GPX("./maggiore.gpx", {
async: true,
marker_options: {
startIconUrl: './lib/leaflet-gpx/pin-icon-start.png',
endIconUrl: './lib/leaflet-gpx/pin-icon-end.png',
shadowUrl: './lib/leaflet-gpx/pin-shadow.png'
}
});
g.on('loaded', function(e) {
map.fitBounds(e.target.getBounds());
});
g.on("addline",function(e){
el.addData(e.line);
});
g.addTo(map);
map.addLayer(service);

All I get is a grey page with zoom control and an empty diagram
do you have the leaftlet.elevation dist files ?
looking at your example you have :
<link rel="stylesheet" href="../dist/Leaflet.Elevation-0.0.2.css" />
<script type="text/javascript" src="../dist/Leaflet.Elevation-0.0.2.min.js"></script
you may copy these files to the lib folder.
