@runhare/next v0.2.1

@runhare/next

Node wrapper for NextJS (https://nextjs.org/) based consumers of RunHare events.

Create a Consumer

Inside your API folder create a new file.

// 'src/pages/api/send-email.ts'
import consumer from '@runhare/next'

interface SendEmail {
  to: string
  subject: string
  content: string
}

interface DemoEvents {
  'send-email': SendEmail
}

export default consumer<RunHareEvents>(
  ['send-email'],
  process.env.CLIENT_SECRET,
  async (event, payload, headers) => {
    console.log(
      `Received Event: ${event} with payload: ${JSON.stringify(payload)}`
    )

    // TODO: Process event

    return { result: 'sucess' }
  }
)

API Reference

Exported types

import { ConsumerOptions, ConsumerResponse } from '@runhare/node'
import { NextApiRequest, NextApiResponse } from 'next'
declare const consumer: <T, K extends keyof T = keyof T>(
  events: (keyof T)[],
  sendKey: string,
  consumerHandler: (
    event: K,
    payload: T[K],
    headers: any
  ) => Promise<ConsumerResponse>,
  options?: ConsumerOptions | undefined
) => (req: NextApiRequest, res: NextApiResponse) => Promise<void>
export default consumer

consumer<T>([events], sendKey, handler) -> nextApiHandler

• [events] : Events this consumer will be processing.
• sendKey : Shared secret used to authenticate request
• consumerHandler : Async function that does the actual message processing.
• options.rejectUnregisteredMessages : If set, messages received not in the subscription list will be marked as failed (potentially retrying them)

Using next-connect

next-connect (https://www.npmjs.com/package/next-connect) is a cool project to allow method routing on API routes on NextJS.

Make sure you use the helper functions .use(...) since the RunHare SDK for Nextjs handles both GET and POST requests (POST to consumer events, GET to get health and stack info)

// 'src/pages/api/send-email.ts'
import { NextApiRequest, NextApiResponse } from 'next'
import nc from 'next-connect'
import consumer from '@runhare/next'

interface SendEmail {
  to: string
  subject: string
  content: string
}

interface DemoEvents {
  'send-email': SendEmail
}

export default nc<NextApiRequest, NextApiResponse>({
  onError: onErrorHandler
}).use(
  consumer<DemoEvents>(
    ['send-email'],
    process.env.CLIENT_SECRET,
    async (event, payload, headers) => {
      console.log(
        `Received Event: ${event} with payload: ${JSON.stringify(payload)}`
      )

      // TODO: Process event

      return { result: 'sucess' }
    }
  )
)
