API

addAsync()

Behaves exactly like seneca.add(), but supports promise-returning functions.

seneca.addAsync('role:hex,color:red', async function(msg) {
  await someAsyncStuff();
  return { color: '#FF0000' };
});

Actions added via addAsync() have an additional priorAsync method in the this context, which is a promisified version of this.prior().

actAsync()

Behaves exactly like seneca.act(), but returns a promise. Also supports callbacks.

const color = await seneca.actAsync('role:hex,color:red');

wrapAsync()

Behaves exactly like seneca.wrap(), but supports promise-returning functions.

seneca.wrapAsync('role:hex', async function(msg) {
  const color = await this.priorAsync(msg);
  color.format = 'css';

  return color;
});

Wrappers added via wrapAsync() have an additional priorAsync method in the this context, which is a promisified version of this.prior().
