Continua
Async Iterator that ongoingly re-runs an iterable-producing function, yielding unseen entries
Example
This project was built to serve an SSDP implementation, which needs to listen on all network interfaces.
Node offers a os.networkInterfaces() call to read the list of interfaces. But which interfaces are available changes over time, and we needed a way to detect & bind to new interfaces as they become available.
continua neatly knits together a way to consume both the initial interfaces and ongoing updates in a unified interface:
for await(const netIf of continua(os.networkInterfaces)){
// bind interface
}
