@libp2p/bootstrap

Peer discovery via a list of bootstrap peers

Install

$ npm i @libp2p/bootstrap

Browser `<script>` tag

Loading this module through a script tag will make it's exports available as Libp2pBootstrap in the global namespace.

<script src="https://unpkg.com/@libp2p/bootstrap/dist/index.min.js"></script>

Usage

The configured bootstrap peers will be discovered after the configured timeout. This will ensure there are some peers in the peer store for the node to use to discover other peers.

They will be tagged with a tag with the name 'bootstrap' tag, the value 50 and it will expire after two minutes which means the nodes connections may be closed if the maximum number of connections is reached.

Clients that need constant connections to bootstrap nodes (e.g. browsers) can set the TTL to Infinity.
