Generate PDF for Stripe invoice using AWS Lambda

This is a lambda function that takes an stripe invoice object (JSON) and customer related info to generate a PDF. The PDF will be saved to a S3 bucket where it could then be distributed (email, download, etc)

Requirements

1. Serverless framework
2. NodeJS 8.10
3. An AWS account

Configuration

1. Fill out your company information on handler.js configuration variables:

const COMPANY_NAME = 'Arena.im'
const COMPANY_ADDRESS = '2443 Fillmore St #380-5512'
const COMPANY_ZIPCODE = '94115'
const COMPANY_CITY = 'San Francisco'
const COMPANY_COUNTRY = 'United States'
const COMPANY_LOGO_PATH = './arena-logo-purple.png'
const COLOR = '#2C75FF'
const S3_BUCKET = 'arena-billing-invoices' //where the PDF generated will be saved

2. Change serverless.yml configuration

Change line 12 to your specific S3 bucket ARN

Change line 32 to include your logo file to the package

Build and Deploy

1. npm install
2. serverless deploy (https://serverless.com/framework/docs/providers/aws/guide/deploying/)

Usage

The lambda function receives an event parameter that is a JSON object with the following structure:

{
  invoice, //actual invoice object from Stripe, see https://stripe.com/docs/api#invoice_object
  clientInfo : { //customer being invoiced info
    client_company_name, 
    client_company_address, 
    client_company_zipcode, 
    client_company_city, 
    client_company_country, 
    receipt_number
  }
}

The function will then generate a PDF and save it to the S3 Bucket defined.
