The Vonage Messages API has been updated to allow sending MMS from US 10DLC, TFN, and Shortcode numbers in the dashboard to other numbers within the United States. To send an MMS using Node.js with the official vonage-node-sdk client library, a basic understanding of JavaScript & Node.js is required, along with a fresh US SMS & MMS capable number. A Vonage API account is also necessary, which includes a public/private key pair for authentication. The Vonage Messages API can be used to send MMS messages from one virtual number to another, but only for A2P (Application to Person) use cases. To set up the API, a new application must be created in the dashboard, and a status URL and inbound URL must be specified, which can point to a mockbin or ngrok service. The code provided uses the vonage-node-sdk client library to send an MMS message using a Node.js script, which logs any errors to the console if the message fails to send, otherwise it logs the message UUID.

The Vonage SMS API is a service that allows developers to send and receive SMS messages using their preferred programming languages, including Java. To use the Vonage SMS API in Java, developers need to create a Java application, configure the Vonage Java SDK, and then send an SMS message using the client object created in the previous step. The Vonage SMS API provides a simple way for developers to integrate SMS functionality into their applications, with features such as support for multiple countries and brands, as well as documentation and resources available to help with implementation.

The Video Video Media Processor API is now available on all supported native platforms (iOS, Android, Windows, and macOS), allowing developers to add custom transformations to their published video.

A developer guide is also available to help create custom transformers using the Media Processor API. Sample applications showcasing the media processor are available for testing and experimentation on different platforms.

ngrok is a tool that creates tunnels, connecting local codebases with public sites without configuration. It's useful for developers who need to share their projects with others or test webhooks in APIs. The tool is free for non-commercial use but requires a paid account for commercial use. Installing ngrok involves installing the agent, creating an account, and connecting it to the account. For Ruby on Rails development, adding ngrok requires modifying the `config/environments/development.rb` file. Common mistakes include leaving HTTPS in the config.hosts, forgetting to restart the rails server after updating the config.hosts, or adding the config.hosts outside of the `Rails.application.configure do` block.

The Vonage SMS API enables businesses to connect with customers via SMS, voice, and messaging apps through its cloud communication platform. The ESP32 microcontroller can be used to control home devices remotely using the Vonage SMS API by setting up a webhook. This involves installing the ArduinoJson and ESPAsyncWebSrv libraries, initializing the web server, handling incoming requests, routing them to functions, and sending responses back to Vonage. Once set up, the system can send requests to Vonage when a digital pin is updated, allowing for remote control of home devices. Ngrok can be used to expose the local endpoint to the internet and receive incoming requests from the Vonage SMS API. The Vonage webhook can then forward these messages to the ESP32, enabling the system to respond to incoming SMS commands.

The authors of the website Vivid's design system documentation site describe how they improved their website's performance by using service workers, which are a powerful tool for web developers that allow them to control communication between the server and client. The main goal was to reduce the number of calls to the server and speed up page load times. To achieve this, they removed prefetching, bundled all files into one big bundle, and implemented caching using service workers. The service worker intercepts requests, caches responses, and returns cached responses on subsequent requests, reducing the need for network requests. They also implemented versioning for their service worker to ensure that users receive the latest version of the application. By implementing these changes, they were able to improve their website's performance, reduce load times, and provide a better user experience.
