Add in your code

require('seneca')()
  .use('seneca-as-promised');

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().
