stellar-js-node-crawler

Crawl the Stellar Network. Identify the nodes and determine their validating
status, version, lag,....

How does it work?

See readme in src/README.md for an overview of the functionality and
architecture.

install

pnpm install

build code

pnpm build: builds code in lib folder

Usage

$3

``
let myCrawler = createCrawler({
nodeConfig: getConfigFromEnv(),
maxOpenConnections: 25,
maxCrawlTime: 900000
});
`

The crawler is itself a
node and needs to be
configured accordingly. You can limit the number of simultaneous open
connections to not overwhelm your server and set the maxCrawlTime as a safety if
the crawler should be stuck.

$3

`
let result = await myCrawler.crawl(
nodes, // [[ip, port], [ip, port]]
trustedQSet, //a quorumSet the crawler uses the determine the latest closed ledger
latestKnownLedger //a previous detected ledger the crawler can use to ignore older externalize messages
);
`

Check out examples/crawl.js for an example on how to crawl the network. You
can try it out using the bundled seed file with the following command:
pnpm examples:crawl seed/nodes.json

Another example is the
Stellarbeat backend

Uses the np package and semantic
versioning.
