postgraphql-hook-demo's Introduction

postgraphql-hook-demo

setup and demo

This demo builds upon postgraphql ^4.0 to show how to send emails via mailgun.

For now, postgraphql-hook is used to help setup the hook. This library may or may not be subsumed into the postgraphql library in some way.

After setting up your mailgun account, follow these steps to send an email through postgraphql:

git clone https://github.com/stlbucket/postgraphql-hook-demo.git

Create a new database to use with the demo - 'pgql_hook' is a good name, but use whatever you like.

Copy 'example_config.js' to 'config.js' in root directory and update the following settings:

DB_CONNECTION_STRING
MAILGUN_API_KEY
MAILGUN_DOMAIN

npm install

If you do not already have knex-migrate installed globally:

npm install -g knex-migrate

knex-migrate up

npm start

Navigate to http://localhost:3000/graphiql and execute this mutation:

mutation {
  sendEmail(input: {
    _fromAddress: "YOUR VALID FROM EMAIL"
    _toAddress: "YOUR VALID TO EMAIL"
    _subject: "Mailgun Test"
    _body: "You got it, you get it, you're gonna get it!"
  }) {
    emailInfo {
      id
      fromAddress
      toAddress
      subject
      body
    }
  }
}

the code that matters

sendEmail.js

const apiKey = process.env.MAILGUN_API_KEY
const domain = process.env.MAILGUN_DOMAIN

const mailgun = require('mailgun-js')({apiKey: apiKey, domain: domain})
const appendMutation = require('postgraphql-hook').appendMutation

async function handler (args, result) {
  const emailInfo = result.data

  const mailgunData = {
    from: `Postgraphql-Mailgun Demo <${emailInfo.fromAddress}>`,
    to: emailInfo.toAddress,
    subject: emailInfo.subject,
    text: emailInfo.body
  }

  console.log('SENDING EMAIL', emailInfo)

  mailgun
    .messages()
    .send(mailgunData, function (error, body) {
      if (error) {
        console.log('MAILGUN ERROR', error)
      } else {
        console.log('MAILGUN RESULT', body)
      }
    })
}

const plugin = appendMutation({
  mutationName: 'sendEmail',
  handler: handler
})

module.exports = plugin

Edit: I know this is super early stuff and you probably didn't expect anyone to find this. I found it in the V4 announcement as I follow postgraphql pretty closely. The npm package postgraphql-hook probably should be transpiled into ES5 in the package and republished.
