You may need to write much of what you need yourself, depending on what you are trying to accomplish - although we have some libraries available, if you download the SDK, you'll see there are some libraries in there, for example, urlUtils.brs, and anything beginning with NWM_
Many roku channels are built as minor modifications of the examples in our SDK.
On the device itself there are a few built in brightscript libraries to help with sprite based graphics and some hex number functions.
For other online resources, look at
LibRokuDev.In addition to the examples in the SDK, many of which are out of date, please see our newer examples on
SourceForge.
There are also plenty of independent Roku based open source projects posted on GitHub which you might find of use or of interest, as well as various useful functions floating around on this forum.
