Project could be tested with command (start) from the user namespace.

Please don't forget to:

• add to root data/dev folder or configure your XTDB connection
• install npm packages, eg yarn

before open your REPL.

Installation

From source

Rocksdb Installation on Ubuntu 18.04, based on https://docs.desmos.network/fullnode/rocksdb-installation/

sudo apt install liblz4-dev
sudo apt-get install -y libgflags-dev libsnappy-dev zlib1g-dev libbz2-dev libzstd-dev
git clone https://github.com/facebook/rocksdb.git
sudo apt-get install g++
sudo apt-get install build-essential
cd rocksdb/
PORTABLE=1 make all

• Clone RocksDB git clone https://github.com/facebook/rocksdb.git && cd rocksdb
• Build Rocks DBDEBUG_LEVEL=0 make shared_lib
• Install RocksDB so that Desmos can access it sudo make install-shared
• Make sure the newly built library is linked correctly sudo ldconfig

make install DB_BACKEND=rocksdb
sudo apt install librocksdb-dev

Add to root folder in the .env XTDB_ENABLE_BYTEUTILS_SHA1="true" OR Edit ~/.zshrc and add the line export XTDB_ENABLE_BYTEUTILS_SHA1=true.

More info at: https://docs.xtdb.com/administration/1.22.0/configuring/ -> Environment Variables

Important: I need to start the repl from terminal (outside of IntelliJ), because that is just a simulated terminal and will not pick up the env correctly, as confirmed by Cursive's author. So, that is the "best practice" for using XTDB.
