This tutorial aims giving an EOSIO dApp developer clear guidelines how to set up a blockchain server and start collecting data for an application. This includes historical and real-time data, such as transaction traces and contract table contents.

Examples in this tutorial are made for telos mainnet. Users of other EOSIO blockchains need to adapt their setup accordingly.

This development is sponsored by Telos blockchain community as part of Worker Proposal #95.

Chronicle is a software package for receiving and decoding the data flow that is exported by state_history_plugin of nodeos, the blockchain node daemon developed by Block One.

chronicle-consumer NPM is a Node.js module for a server-side application that needs to receive blockchain updates from Chronicle. It comes along with a number of examples that illustrate how to collect data for some dApps on Telos.
