libp2p Demos

Demo 1: DHT Peer & Content with Go and JS Nodes

Directory: content-dht-provide-find

What it demonstrates: A new DHT is created by the Go program dht-interop. In a separate terminal or machine, a Node.js program connects to this DHT. One connected, each verifies that it can find the other's content via the DHT.

First terminal:

cd content-dht-provide-find
make
./dht-interop

Second terminal: run the command printed out by dht-interop, replacing 127.0.0.1 with the IP of the server where dht-interop is listening. Example:

First time only:

cd js-dht-test
npm install

Running the Node.js program:

node js-dht-test/index.js /ip4/127.0.0.1/tcp/9876/ipfs/QmehVYruznbyDZuHBV4vEHESpDevMoAovET6aJ9oRuEzWa

Note that the node ID of dht-interop is always Qm...6aJ9oRuEzWa because it is being read in from util/private_key.bin (a private key marshalled to X.509 generated by util/private-key-gen). This is to keep the peer id of the bootstrap server stable across invocations.

Demo 2: PubSub

Directory: pubsub

What it demonstrates: Two Go nodes are created and run a chat server using a shared PubSub topic. TODO: Should be a Go node and a JS node, once I get the two Go nodes version working.

TODO: show how to run
