  handler: (req, reply) => {
    reply.act({ topic: 'math', cmd: 'add', a: req.query.a, b: req.query.b })

fastify.route({
  method: 'GET',
  url: '/math/add',
  handler: async function (req, reply) {
    let resp = await req.hemera.act({ topic: 'math', cmd: 'add', a: req.query.a, b: req.query.b })
    // access result
    resp.data
    // retain parent context
    resp = resp.context.act(...)
  }
})

Test

Testsuite makes use of hemera-testsuite, so your setup should meet it's prerequisits, esp.:

A nats server must be installed on your machine nats.io and executable as gnatsd. So add nats-server as gnatsd to your PATH as alias, link whatever works. Check if it's available:

$ gnatsd --help

Usage: nats-server [options]

[...]

Now test should succeed by running:

$ yarn test
