Environment Setup

The following instructions for how to setup your development environment for NEO Tracker are known to work on Mac, but should work on any Unix-like system.

Requirements

• Postgres 10.3
• Node 9.11.1
• NEO•ONE

Setup Postgres

We will use the $PGDATA environment variable in the following examples. You may set this variable with export PGDATA=<directory to store database> if it's not set. For example, on Mac you can use the default data directory with export PGDATA=/usr/local/var/postgres

• initdb $PGDATA (initialize the data directory)
• pg_ctl -D $PGDATA start (start postgres)
• createdb neotracker_priv (create the database for NEO Tracker)

Start a NEO•ONE private network

NEO Tracker is best developed against a private network, which we can setup easily with NEO•ONE.

• yarn global add @neo-one/cli (install NEO•ONE)
• neo-one create network priv (create the private network)
• neo-one bootstrap --network priv (bootstrap the private network with test data)

By default, NEO•ONE will create a private network with the RPC url http://localhost:40200/rpc, but in case it's different on your setup, you can look it up with neo-one describe network priv for use in the next step.

Start NEO Tracker

• yarn develop:scrape (start the scraper which populates postgres with blockchain data)
• yarn develop:web (start the webserver on http://localhost:1340)

In both of the above commands, prefix with NEOTRACKER_RPC_URL=<rpc_url> where rpc_url is the one you found with neo-one describe network priv if it's different from the default. E.g. NEOTRACKER_RPC_URL=http://localhost:40200/rpc yarn develop:scrape.

General Tips

• List wallets on the private network using neo-one get wallet --network priv. Grab the private key for a wallet to use for testing with neo-one describe wallet <wallet_name> --network priv.
• Start from a clean slate by deleting the NEO•ONE network and dropping the postgres tables
  • neo-one delete network priv (delete the NEO•ONE private network)
  • yarn develop:drop-tables (drop the NEO Tracker tables)
