Not ready for production. Work-in-progress. Instructions may not yet be functional.
Install
npm install @wsdot/bridge-vcUse
This sample demonstrates using this code via JavaScript Modules. You can also use Webpack (or a similar tool) to bundle your code and the imported modules together to be compatible with more browsers.
index.mjs
This is the code for the demo page's JavaScript Module.
// import functions
import { createControl, fetchCrossingInfo } from "./node_modules/@wsdot/bridge-vc/dist/esm/index.mjs";
// Get crossing location ID URL search parameter.
const urlSearchParams = new URLSearchParams(location.search);
const idString = urlSearchParams.get("id");
const crossingId = parseInt(idString);
// Write error message if ID is invalid.
if (isNaN(crossingId)) {
const p = document.createElement("p");
p.textContent = `invalid crossing id: ${idString}`;
document.body.appendChild(p);
} else {
// Query SOE for crossing location info,
// then create control displaying that info.
const mapServiceUrl =
"https://www.example.com/arcgis/rest/services/Bridge/BridgeVerticalClearance/MapServer";
fetchCrossingInfo(crossingId, mapServiceUrl).then(
result => {
const control = createControl(result);
document.body.appendChild(control);
},
error => {
const p = document.createElement("p");
p.textContent = error.message;
document.body.appendChild(p);
}
);
}If using webpack and / or TypeScript, the import statement would be slightly different. Only the package name is used, instead of the path to the packages main module script file.
import { createControl, fetchCrossingInfo } from "@wsdot/bridge-vc";index.html
