import corenlp-ts from 'corenlp-ts';

function printDepParse(g: DependencyGraph, relation = 'root', depth = 0, visited = new Set<DependencyGraph>()): void {
  console.log(`${'  '.repeat(depth)}${relation}: ${g.token.word} (${g.token.index})`);
  if (!visited.has(g)) {
    visited.add(g);
    for (const dep of g.dependents) {
      printDepParse(dep.dependent, dep.relation, depth + 1, visited);
    }
  }
}

const nlp = new CoreNLP('http://localhost:9000');
const res = await nlp.annotate('She flew to Bali or to Turkey', { annotators: ['depparse'] });
printDepParse(res.sentences[0].toDependencyGraph());
