You can query the REST endpoint of a hosted feature layer in ArcGIS Online. However, there's no option to measure the distance from the input geometry. That would require a geoprocessing task of some kind. A quick search didn't reveal anything like that available in ArcGIS Online but I'm not that familiar with that stuff. Here's an example hosted feature layer and here's a URL to query the first 8 records within 100 miles of the input geometry (point as lon/lat). Changing the f=pjson to f=html will let you see the all the query parameters available. https://services7.arcgis.com/LXCny1HyhQCUSueu/arcgis/rest/services/Definitive_Healthcare_USA_Hospital_Beds/FeatureServer/0/query?where=1%3D1&objectIds=&time=&geometry=-90.270527%2C+38.637732&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&resultType=none&distance=100&units=esriSRUnit_StatuteMile&returnGeodetic=false&outFields=&returnGeometry=true&featureEncoding=esriDefault&multipatchOption=xyFootprint&maxAllowableOffset=&geometryPrecision=&outSR=&datumTransformation=&applyVCSProjection=false&returnIdsOnly=false&returnUniqueIdsOnly=false&returnCountOnly=false&returnExtentOnly=false&returnQueryGeometry=false&returnDistinctValues=false&cacheHint=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&having=&resultOffset=0&resultRecordCount=8&returnZ=false&returnM=false&returnExceededLimitFeatures=true&quantizationParameters=&sqlFormat=none&token=&f=pjson ...

Sounds like you want to create an API rather than a web app. Look into publishing a geoprocessing service. ... View more

You can set the color but I don't think font weight applies to SVG icons. In your sample, why can't you change the color property on line 82 where you define the textSymbol for drawing the point? Also, if you are adding the icon with your own html, you can change the class name to change the color. ... View more

Keep in mind that you'll probably need to connect as the owner of the table to rename it. Depending on how your database is organized, you may need to work out a way to reconnect as the appropriate user each time you encounter a new schema. I did something similar here that you can use for ideas. ... View more

I'm not really sure how visible: false works on the back end of the API. I just tested this with the Query features from a FeatureLayer sample by taking out visible: false where the quakesLayer FeatureLayer was defined and removing the quakesLayer from the layers property where the map was initialized. The app still seemed to function normally. Do some experiments with your own app to be sure. As for creating a symbol, check out the Symbol Playground. ... View more

Check out this sample. The quakesLayer FeatureLayer is defined with visible: false so it doesn't display in the map. Then, the section at the end with the last three functions section of code is what queries the quakes and displays them. // query for earthquakes with the specified magnitude // within the buffer geometry when the query button // is clicked queryQuakes.addEventListener("click", function () { queryEarthquakes().then(displayResults); }); function queryEarthquakes() { var query = quakesLayer.createQuery(); query.where = "mag >= " + magSlider.values[0]; query.geometry = wellBuffer; query.spatialRelationship = "intersects"; return quakesLayer.queryFeatures(query); } // display the earthquake query results in the // view and print the number of results to the DOM function displayResults(results) { resultsLayer.removeAll(); var features = results.features.map(function (graphic) { graphic.symbol = { type: "simple-marker", // autocasts as new SimpleMarkerSymbol() style: "diamond", size: 6.5, color: "darkorange" }; return graphic; }); var numQuakes = features.length; document.getElementById("results").innerHTML = numQuakes + " earthquakes found"; resultsLayer.addMany(features); } Notice the results are added to a GraphicsLayer called resultsLayer. That is defined earlier as var resultsLayer = new GraphicsLayer(); ... View more

Welcome! When executing a query, you can specify geometry to use as a spatial extent (intersect) for the results. Here's a sample. ... View more

It looks like you're already getting your query parameters and setting an expression. However, it doesn't look like you're doing anything to query or highlight the features. Take a look at this sample. ... View more
