Vagrant X Ruby On Rails

I'm the bigfan of gorails.com website and I'm using for the past 5 years. It helps me to setup Ruby on Rails locally either on Windows or Ubuntu.

For Vagrant, I'm following this article to setup it with Ruby on Rails: https://gorails.com/guides/using-vagrant-for-rails-development

Issue

There is multiple when following those article. Hence, I decided to configure it manually where Vagrant only works as ruby interpreter and PostgreSQL installed on the host operating system.

async (event, steps) => {
  // NodeJS implementation in Pipedream of "Intent to Receive" for Xero webhooks

  const { createHmac } = await import('crypto');
  const xero_webhook_key = 'OSd0eLlVIY9ZhViEqlDUh4+6n6M+Lo+eDaEJheJ6OCCgWwIz2D3JIAU6jPMipHRbgKTLz2uJ+xiACXGDBLrgdA==' // Get this from the Xero app
  const body_string = Buffer.from(steps.trigger.raw_event.body_b64, 'base64').toString() // Use RAW body data so that Pipedream doesn't break our data
  const xero_hash = steps.trigger.event.headers["x-xero-signature"] // Could probably shorten, but keeping it long for consistency

  let our_hash = createHmac('sha256', xero_webhook_key).update(body_string).digest("base64") // Generate the hash Xero wants
  let statusCode = xero_hash == our_hash ? 200 : 401 // If the hashes match, send a 200, else send a 401
