Developers working with the Moddable SDK have an amazing amount of material to help. This page is a guide to many of the the resources available including articles, example code, reference documentation, and places to get answers to questions.
The Getting Started guide provides step-by-step instructions to install the Moddable SDK for use in development on macOS, Windows, and Linux.
The Moddable SDK supports development for a wide range of microcontrollers. There are set-up guides is for each supported microcontroller. Each guide includes step-by-step instructions to install and configure the required build tools. They also include a list of supported development boards.

The Moddable SDK repository on GitHub contains the source code to the runtime and build tools. It also contains extensive documentation and example code.
The Moddable SDK brings together two different disciplines – embedded software engineering and JavaScript software development. Most people coming to the the Moddable SDK have experience with one of these but not the other. A great place to start is our book IoT Development for ESP32 and ESP8266 with JavaScript. For developers combing from an embedded background, it contains a fast-paced introduction to the JavaScript language written specifically for C and C++ developers. For JavaScript developers who haven't worked directly with hardware before, it introduces fundamental hardware concepts. And for developers of all backgrounds, it contains hundreds of practical code examples to perform common tasks.
Sometimes it is easier to learn by watching a video than reading a document. The Moddable YouTube channel contains tutorials and demonstrations to help.
Quick demo of using message tracing in xsbug, the Moddable SDK's JavaScript debugger. The message view is a useful tool for visualizing communication in IoT projects.
A quick look at the core features of mcsim including device selection, show controls and the information bar, rotating the screen, and light/dark mode selection.
A touch screen remote for selecting Photoshop Tools that you can easily customize or adapt to support other apps!
Demonstration of the JavaScript Fetch API from HTML5 running on a microcontroller. It shows a GET for the text of a web page, a JSON PUT with JSON response, and GET of JPEG image data. The example script uses asynchronous JavaScript functions to simplify the code.
Moddable Hardware is high-quality, low cost modules that are fully compatible with the Moddable SDK. Our hardware is designed to be paired with the Moddable SDK, eliminating the need for any special set‑up or configuration.
Moddable One is powered by the 80 MHz ESP8266 microcontroller with integrated Wi‑Fi and 80 KB of RAM.
Moddable Two is powered by the popular ESP32 microcontroller with two 240 MHz CPU cores, integrated Wi‑Fi, and BLE.
Moddable Three features an ePaper screen for elegant, unobtrusive display in any environment.
Year-long operation on a coin cell with BLE a fast, always-on screen, and Nordic's ultra-low power nRF52.
Some developers like to read the documentation before they start coding. Others prefer to jump in, modifying existing projects to explore how things work. The Moddable SDK has resources to support both approaches.
The examples directory contains a constantly growing collection of nearly 200 ready-to-run projects. Many run on the simulator, so no additional hardware is required. Each example is focused on demonstrating a particular capability. The example are generally less than a page of code, making them easy to understand. There's helpful video tutorial that introduces the examples and shows how to run them.
The documentation directory contains an extensive collection of reference materials for the APIs in the Moddable SDK. These are a great resource to browse to get a better understanding of the many capabilities available for projects to use. There are also many documents describing details about the XS JavaScript engine.
The Moddable SDK is constantly growing and improving thanks to the work of the Moddable team and contributions for the world-wide Moddable community. There are several ways to stay informed about the latest advances.

The @moddabletech X feed has the latest news for developers using the Moddable SDK. There are posts about software updates, new blog posts, and contributions from the community. Following @moddabletech is the easiest way to receive all the latest.
The Moddable blog is an extensive collection of news and articles about getting the most from the Moddable SDK. New articles are posted regularly.
To receive a notification as soon as a new release of the Moddable SDK is available, Click the "Watch" button on the Moddable SDK repository. Each releases is accompanied by detailed release notes that summarize the additions, enhancements, and fixes.
Even with all the great resources available to support developers working with the Moddable SDK, there are times when the solution to a problem just isn't apparent. The Moddable community provides many ways to interact with other developers to ask questions, discuss ideas, and share knowledge.
To ask questions about the Moddable SDK, GitHub Discussions is a good place to start. Questions and ideas can be posted to the Moddable community. The Moddable team monitors Github Discussions and often answers questions there.
Every month we get together for an informal community call to talk about embedded JavaScript news including Moddable SDK updates, ECMA-419, events, and interesting projects. This is a community event so bring your announcements to share and questions to ask.
To report a bug in the Moddable SDK, use GitHub Issues. Reporting bugs is very helpful, even if there's a workaround, because it ensures the problem can be fixed for all developers using the Moddable SDK.
The Moddable community uses Gitter for realtime conversations. This is a good place to ask a quick question before opening a Discussion or Issue.
While a little unusual, some questions can be answered with a tweet. Mention @moddabletech in the tweet to make sure Moddable is notified.
