NEO Tracker is a Neo blockchain explorer and wallet.

Welcome to the NEO Tracker community! We're always looking for more contributors and are happy to have you. Documentation on how to contribute can be found here.

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.

• Node 10.16.0
• NEO•ONE

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

• yarn install (install dependencies, including @neo-one/cli)
• yarn neo-one start network (starts a private network)

By default, NEO•ONE will create a private network with the RPC url http://localhost:9040/rpc, but this can be configured in a NEO•ONE configuration file. Note for this purpose, only the network option is relevant.

• yarn install (install dependencies)
• yarn develop (starts a watched instance of NEO Tracker for development)

By default, yarn develop sets up a SQLite database in the neotracker root directory. If you'd prefer to work with Postgres 10.3, this and other options can be configured in a .neotrackerrc file. See below for the full list of configurable options.

If you'd like to use Postgres 10.3, here are some instructions for getting started.

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 macOS you can use the default data directory with export PGDATA=/usr/local/var/postgres. To make this a "permanent" environment variable, for use in other sessions, you'll want to add export PGDATA="/usr/local/var/postgres" to your .bashrc or .zshrc file(s).

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

To connect this database with neotracker, in the .neotrackerrc file, set dbClient to pg and dbPort to the port the postgres server was started on (defaults to 5432).

• To reset the local database, simply run yarn develop --resetDB.

The full list of configurable options in the .neotrackerrc file. These can be added to the file or passed in as cli arguments.

      "filename": "db.sqlite" // local sqlite database filename
    }
  },

    "googleAnalyticsTag": "", // Google Analytics Tag
  }
}

with a postgres db we have two connection options, a connection string or connection object.

connection string configuration:

{
  "db": {
    "client": "pg",
    "connection": "postgresql://localhost:5432/neotracker_priv"
  }
}

connection object configuration:

{
  "db": {
    "client": "pg",
    "connection": {
      "host": "localhost",
      "port": 5433,
      "user": "admin" // optional username
      "password": "password" // optional password
      "database": "neotracker_priv" // optional database name
    }
  }
}
