It's a great place to get started - All the samples in this repository are built with JS code and demonstrate primary usage in the API. The io-sample - Demonstrates how to open and load a file to your app, Display it, Add some content, and Write it back to the file.In our APIs sample apps repository, you can find and download a sample app that demonstrates the usage in the IO API: overwolf.io.ReadBinaryFileResult Object.overwolf.io.ReadFileContentsResult Object.overwolf.io.enums.fileListenerState enum.In addition, the simple I/O plugin offers several more general I/O features that are not available through the APIs.
