connect()

This chapter describes the functions and properties related to the connect family of features.

Where the name Flowee is used, this is the variable which results from a call similar to:

const FloweeServices = require('floweejs');
var Flowee = new FloweeServices();

Functions

Flowee.connect()

This function starts a (new) connect to a Flowee server-pair. It is implicitly calling both a connectHub() and a connectIndexer().

Parameters

  • Hostname (optional)
    This is the hostname or IP address to connect to. If none is provided then the connection will be opened to api.flowee.org.

Return-value

This function returns a promise. Notice that the promise in some cases requires at least NodeJS v12.6

Flowee.connectHub()

This function starts a (new) connect to Flowee the Hub, which is the main database for transaction and block-data and is able to receive new transaction you may have created.

Parameters

  • Hostname (optional)
    This is the hostname or IP address to connect to. If none is provided then the connection will be opened to api.flowee.org.
  • port (optional)
    The port that the server is listening on. By default this is 1235.

Return-value

This function returns a promise. Notice that the promise in some cases requires at least NodeJS v12.6

Flowee.connectIndexer()

This function starts a (new) connect to Flowee Indexer, which hosts one or more indexes which allow fast lookup. Things like finding the transaction matching a txid, or which transactions deposited funds in a certain address.

Parameters

  • Hostname (optional)
    This is the hostname or IP address to connect to. If none is provided then the connection will be opened to api.flowee.org.
