0.9.1 / 2018-05-07

• Add new logger methods:

B.series([
  B.log('sending hello'),
  B.info('sending hello'),
  B.warn('sending hello'),
  B.error('sending hello'),

  B.sendText('hello'),
]);

It supports template too.

B.series([
  B.log('user: {{ session.user.id }} x: {{ state.x }}'),
  B.sendText('hello'),
]);

You can use your owner adapter for the logger:

const { log, info, warn, error } = B.createLogger({
  log: debug('log'),
  info: debug('info'),
  warn: debug('warn'),
  error: debug('error'),
});

B.series([log('sending hello'), B.sendText('hello')]);
