Usage

This example shows you how to create a math service with an add action which can add two numbers.

const { Weave } = require('@weave-js/core')

const broker = Weave({
    nodeId: 'my-first-node'
})

broker.createService({
  name: 'math',
  actions: {
    add(context) {
      return Number(context.data.a) + Number(context.data.b)
    }
  }
})

broker.start()
  .then(() => {
    // Call service
    broker.call('math.add', { a: 5, b: 3 })
      .then(result => console.log('5 + 3 =', result))
      .catch(error => console.error(`Something went wrong! ${error.message}`))
