Express Docs v0.1.0


Express Docs / default

Variable: default ​

const default: object

Defined in: src/index.ts:111

Type Declaration ​

__diagnostics ​

__diagnostics: () => DiagnosticsInfo

Returns build-time diagnostics. Safe to call at any time — never throws, never exposes secret values (only key names, not values).

Returns ​

DiagnosticsInfo

ExpressButtons ​

ExpressButtons: (config) => ExpressButtonsInstance

Creates an ExpressButtonsInstance that manages one or more express checkout button providers.

The returned instance is inert until render() is called. Provider SDK loading, telemetry initialization, and button rendering all happen lazily inside render().

Parameters ​

config ​

ExpressButtonsConfig

The full configuration object describing which providers to render and the callback handlers (onClick, onCancel, onError).

Returns ​

ExpressButtonsInstance

An ExpressButtonsInstance with render(), teardown(), and teardownProvider() methods.

Example ​

ts
const buttons = CollanaPay.ExpressButtons({
  providers: [
    {
      providerProtocolType: 'PayPal',
      paymentMethodType: 'PayPalExpress',
      container: '#paypal-btn',
    },
  ],
  onClick: async (identity) => {
    const resp = await fetch('/api/orders', { method: 'POST' });
    const data = await resp.json();
    return data.checkoutData; // base64-encoded string from backend
  },
  onCancel: (identity) => { console.log('Cancelled', identity.paymentMethodType); },
  onError: (error) => { console.error(error.code, error.message); },
});
await buttons.render();
