Here is a neutral and interesting summary of the provided text in one paragraph: To build an emergency contact notification system with Twilio SMS, developers need to install Node.js 14.16 or above, create a free Twilio account, obtain a Twilio phone number, and set up the Twilio CLI on their machine. They then initialize a new Functions service, add their Twilio credentials, and define a function that will send an SMS to all emergency contacts with one text message. The function includes a list of emergency contact phone numbers, a custom message, and error handling for failed sending attempts. Once the app is coded, it can be deployed using the Twilio CLI and connected to a Twilio phone number through the Twilio Console. With this system, users can quickly notify multiple people with one quick message in an emergency situation, potentially getting help faster or reuniting their family sooner.
