Let's do some future-proofing

We talked a lot about how awesome libp2p is as a modular and future-proof network stack. So, let's see it in action.

Try it yourself

• Install the correct version of the multiaddr library: ^6.1.0 or above
• Add (/ip4/0.0.0.0/tcp/0) tcp and (/ip4/0.0.0.0/tcp/0/ws) websocket multi address to the nodes.

  Note that using 0 as port automatically takes any available port

• Console log all the multiaddress associated to the node
• Run the code, do you see a multiaddress with tcp and ws ? If so, congratulations, you have just demonstrated future-proofing and modularity!

Hints

• libp2p.peerInfo.multiaddrs() gives the list of all the multiaddress associated to the libp2p node
• libp2p.peerInfo.multiaddrs.add(addressString) can be used to add multiaddress
