Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

• Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
• Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
• Async methods return Task<T> instead of Promise<T>
• Objects should be disposed with using statements
• Access via JS.Get<WorkerOptions>(...) or constructor new WorkerOptions(...)

Using Trusted Types

if (typeof trustedTypes === "undefined")
  trustedTypes = { createPolicy: (n, rules) => rules };

Using Trusted Types

const workerScriptAllowList = [
  // Some list of allowed URLs
];
const policy = trustedTypes.createPolicy("worker-url-policy", {
  createScriptURL(input) {
    if (workerScriptAllowList.includes(input)) {
      return input; // allow the script
    }
    console.log(`Script not in workerScriptAllowList: ${input}`);
    return ""; // Block the script
  },
});

Using Trusted Types

// The potentially malicious worker URL
// We won't be including untrustedScript in our workerScriptAllowList array
const untrustedScriptURL = "https://evil.example.com/naughty.js";

// Create a TrustedScriptURL instance using the policy
const trustedScriptURL = policy.createScriptURL(untrustedScriptURL);

// Construct the worker with the trusted URL
const myWorker = new Worker(trustedScriptURL);
