Email Configuration Setup

Overview

This application uses environment variables for email configuration instead of Firebase Functions config (which is being deprecated).

Required Environment Variables

Email Server Configuration

EMAIL_HOST - SMTP server host (default: smtp.gmail.com)
EMAIL_PORT - SMTP server port (default: 587)
EMAIL_SECURE - Use secure connection (default: false)
EMAIL_USER - SMTP username/email
EMAIL_PASS - SMTP password or app password
EMAIL_FROM - From email address (default: noreply@cim-summarizer.com)

Weekly Email Recipients

WEEKLY_EMAIL_RECIPIENT - Email address for weekly summary reports (default: jpressnell@bluepointcapital.com)

Setup Instructions

For Local Development

Create a .env file in the backend directory
Add the required environment variables:

EMAIL_HOST=smtp.gmail.com
EMAIL_PORT=587
EMAIL_SECURE=false
EMAIL_USER=your-email@gmail.com
EMAIL_PASS=your-app-password
EMAIL_FROM=noreply@cim-summarizer.com
WEEKLY_EMAIL_RECIPIENT=recipient@example.com

For Firebase Functions (Production)

Set environment variables using Firebase CLI:

firebase functions:config:set email.host="smtp.gmail.com"
firebase functions:config:set email.port="587"
firebase functions:config:set email.secure="false"
firebase functions:config:set email.user="your-email@gmail.com"
firebase functions:config:set email.pass="your-app-password"
firebase functions:config:set email.from="noreply@cim-summarizer.com"
firebase functions:config:set email.weekly_recipient="recipient@example.com"

IMPORTANT: After December 31, 2025, you must migrate to environment variables:

firebase functions:config:unset email

And set environment variables instead:

firebase functions:secrets:set EMAIL_HOST
firebase functions:secrets:set EMAIL_PORT
firebase functions:secrets:set EMAIL_SECURE
firebase functions:secrets:set EMAIL_USER
firebase functions:secrets:set EMAIL_PASS
firebase functions:secrets:set EMAIL_FROM
firebase functions:secrets:set WEEKLY_EMAIL_RECIPIENT

Gmail Setup (Recommended)

Enable 2-factor authentication on your Gmail account
Generate an App Password:
- Go to Google Account settings
- Security → 2-Step Verification → App passwords
- Generate a password for "Mail"
Use the generated password as EMAIL_PASS

Testing

Use the test script to verify email configuration:

cd backend
npm run test:email

Migration from functions.config()

The application has been updated to use environment variables directly instead of functions.config(). This change ensures compatibility after the Firebase Functions configuration API is deprecated on December 31, 2025.
