Web Streams are part of the Web’s foundation. But they’ve been out of reach for Embedded JavaScript. Until now. 🔥Moddable found a way to run streams efficiently on microcontrollers.🎉 Our blog tells the story of this huge step forward for embedded devs. moddable.com/blog/web-stream…

Web Serial was invented so PCs could talk to microcontrollers. Now microcontrollers can talk back using Web Serial, thanks to Moddable's new Web Streams.

Our Guides are a new kind of documentation, designed for Embedded JavaScript developers and their LLMs. Their code-first approach pairs small code snippets paired with concise explanations. They show how to perform common tasks simply. moddable.com/blog/guides/

Grok one-shotted the JavaScript driver for this Alphanumeric display run over Qwiic (I2C). It's shown running on the qtpys3, but since it is written to the ECMA-419 spec, it can run on nRF52840, Pico, other ESP32 variants without change. Thanks @grok @moddabletech

At Moddable, we believe industry standards can transform software development. Our latest blog post shows how ECMA-419 simplifies Bluetooth Low Energy development by a couple orders of magnitude and reduces DNS-SD integration to a few lines of JavaScript. moddable.com/blog/ecma-4/
