Hi Bob, it seems like this is a duplicate post. let's move the accuracy discussion to this other thread => https://community.esri.com/t5/arcgis-api-for-javascript-questions/poor-accuracy-of-locate-widget/m-p/1192491#M77928

Hi @BobCowling2 thanks for reaching out, can you please open a support ticket? That way they can gather all the necessary information from your set up. The bouncing around might be related to spurious location values not being filtered out.

Hi @DamonDamon here are Mozilla's guidelines for trying to address problems similar to yours: https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration. Have you looked into this?

Hi All, Please provide a simple GitHub repo that reproduce these errors so that we can investigate your issue. We recommend you start with one of our ES modules samples: https://github.com/Esri/jsapi-resources/tree/master/esm-samples. "unexpected token" errors are very common in JavaScript. It's related to a parsing error in the code. With JavaScript frameworks, this is most commonly caused by configuration issues.

@turbolego can you share your package.json and tsconfig here? Also, please retest using the .browserslistrc file I link to above, and then try setting your tsconfig to target ES2020.

Hi @Anirban_Banerjee we recommend using ES modules "@arcgis/core" with new React projects rather than esri-loader. Here is a working example: https://github.com/Esri/jsapi-resources/tree/master/esm-samples/jsapi-create-react-app.

@turbolego thanks for sharing, we'll look into this further. I'm not liking that you had to downgrade your JS API version to get it to work.

Hi @turbolego those errors seem to be showing a configuration issue in Angular and not an issue with arcgis/core. Did the app work with a previous version of arcgis/core? We'll need a simple a GitHub repo that reproduces the issue. Also, check your TSConfig and browserslistrc. Here's the browsers list from our Angular 11 sample (~early 2021, v4.19) https://github.com/Esri/jsapi-resources/blob/9b4b278c2611f413fdfaa8c880177052fda9e336/esm-samples/jsapi-angular-cli/.browserslistrc and tsconfig https://github.com/Esri/jsapi-resources/blob/9b4b278c2611f413fdfaa8c880177052fda9e336/esm-samples/jsapi-angular-cli/tsconfig.json

Correct, we measure a variety of stats including the size of the entire build folder for each of the samples. A 1GB folder could the the result of things like configuration issues, third party libraries, a very large and complex application, lots of image files, etc.

@JamesBrett Nope, that doesn't sound right. Can you provide a simple github repo that we can look at? Here are our sample app build sizes for comparison: https://github.com/Esri/jsapi-resources/blob/master/esm-samples/.metrics/4.23.0.csv

I also updated my previous code snippet to hopefully make the pattern more clear.

Oh, whoops, you have to import the module first, here's a working AMD codepen example: https://codepen.io/andygup/pen/rNJrbzM?editors=1000. <html>
<head>
<meta charset="utf-8" />
<meta
name="viewport"
content="initial-scale=1,maximum-scale=1,user-scalable=no"
/>
<style>
html,
body,
#viewDiv {
padding: 0;
margin: 0;
height: 100%;
width: 100%;
}
</style>
<link
rel="stylesheet"
href="https://js.arcgis.com/4.23/esri/themes/light/main.css"
/>
<script src="https://js.arcgis.com/4.23/"></script>
<script>
require(["esri/Map",
"esri/views/MapView",
"esri/core/reactiveUtils"], (Map, MapView, reactiveUtils) => {
const map = new Map({
basemap: "topo-vector"
});
const view = new MapView({
container: "viewDiv",
map: map,
zoom: 4,
center: [15, 65]
});
const handle = reactiveUtils.when(
// getValue function
() => view.updating === false,
// Callback function
() => {
console.log("view update: ", view.updating);
}
);
});
</script>
</head>
<body>
<div id="viewDiv"></div>
</body>
</html> With ES modules the import pattern would look like this: import { when } from "esri/core/reactiveUtils";
when(() => item.layer.visible === true, () => layerListFormat(item));
when(() => item.layer.visible === false, () => layerListFormat(item));

We are updating the docs for 4.24. This might help in the meantime: // watchUtils
watchUtils.whenTrue(foo, "some.value", () => console.log("True"));
watchUtils.whenFalse(foo, "some.value", () => console.log("False"));
// Equivalent in reactiveUtils
reactiveUtils.when(() => some.value === true, () => console.log("True"));
reactiveUtils.when(() => some.value === false, () => console.log("False"))

Oh, one more thought. Even if it is a life-cycle issue related to something like a Symbol.iterator, we'd still need a repro case to figure out what part of the API might be choking.
