Decode Messages(Event)

How to decode messages with ABI

SDK can decode ABI-compatible External Inbound, External Outbound and Internal messages.
Types of messages
ABI-compatible contracts generate abi-compatible messages, or, to be exact, abi-compatible message bodies :)
So, if you have ABI on hands, you can decode these messages.
You can use both full message boc for decoding and only message body for decoding.
Let's decode!
Core SDK provides 
decode_message method for full boc of message decoding 
decode_message_body method for only message body decoding.
Usage
const decoded = (await client.abi.decode_message({
        abi: abiContract(HelloEventsContract.abi),
        message: boc,
    }));
switch (decoded.body_type) {
case MessageBodyType.Input:
    log_.push(`External inbound message, function "${decoded.name}", fields: ${JSON.stringify(decoded.value)}` );
    break;
case MessageBodyType.Output:
    log_.push(`External outbound message (return) of function "${decoded.name}", fields: ${JSON.stringify(decoded.value)}`);
    break;
case MessageBodyType.Event:
    log_.push(`External outbound message (event) "${decoded.name}", fields: ${JSON.stringify(decoded.value)}`);
    break;
}
