# lws minimal secure streams binance

This is a Secure Streams version of minimal-ws-client-binance.

"policy.json" contains all the information about endpoints, protocols and
connection validation, tagged by streamtype name.

The example tries to load it from the cwd, it lives in
./minimal-examples/secure-streams/minimal-secure-streams-binance dir, so
either run it from there, or copy the policy.json to your cwd.  It's also
possible to put the policy json in the code as a string and pass that at
context creation time.

The secure stream object represents a nailed-up connection that outlives any
single socket connection, and can manage reconnections / retries according to
the policy to keep the connection nailed up automatically.

Secure Streams provides the same simplified communication api without any
protocol dependencies.

## build

Lws must have been built with `LWS_ROLE_WS=1`, `LWS_WITH_SECURE_STREAMS=1`, and
