Using the captcha-less iosec antibot verification
import { CONFIG, Iosec, IosecOptions } from "@iocaptcha/client";
// should throw errors instead of returning them?
// CONFIG.throw_errors = true;
const iosec = new Iosec();
function tokenCallback(token) {
console.log("New iosec token: " + token)
// You can now use the token to verify the user by
// sending the token to your server, and verifying it
// using the server-side SDK (https://npmjs.com/package/@iocaptcha/server)
// or by direct HTTP api calls (https://docs.io.software/api)
}
// Create options with the tokenCallback function, to receive new tokens.
// The callback will be called within ~3 seconds (depending on endpoint difficulty).
const options = {
public_key: "AAAA",
action: "submit-form-1",
callbackTokenRefresh: tokenCallback,
callbackError: (err) => {
console.error("Error during token refresh:", err);
}
}
// Executes the iosec widget and starts the process
let widget = iosec.execute(options);
// OPTIONAL: Verify that no errors happened during execution
if (widget instanceof Error) {
console.error("Error during widget creation!");
} else {
console.log("Widget created successfully.")
}
// the tokenCallback function will now be called within a few seconds, depending on the endpoint difficulty.Implicit rendering
// Sometimes, you might want to render the widget yourself in a pre-specified DOM element.
// This can be done by using the execute_with_implicit_dom function.

The UMD version does not differ from the ES6 version, except a global "iosec" object is added to the global scope. The size of the UMD version is approx. ~3kb (minified + gzipped).
