Running hREA Backend
These are instructions for doing set up, and running, of a holochain runtime on your device containing the hREA hApp, for the sake of a development environment.
Before trying to develop a user interface or service on top of hREA, you need to be running the hREA backend, within a holochain runtime.
You need to install some packages to your command line, which you can do manually, or via the nix-shell dev environment manager. There are instructions for either way that you choose right below this, just click to expand the section you would like to follow.
Install the following to your system, via Rusts package manager "cargo".
The following installs a holochain developer tools binary to your system, accessible as the binary
hc on your system.cargo install holochain_cli --version 0.1.3 --locked
The following installs the core holochain runtime to your system, accessible as the binary
holochain on your system. It can be used directly, or implicitly via the hc sandbox calls that we make next.cargo install holochain --version 0.1.3 --locked
The following is the secure private key enclave that
holochain uses for cryptography. It is available as a binary on your path lair-keystore, but holochain manages these subprocesses automatically on your behalf.cargo install lair_keystore --version 0.2.3 --locked
Set up a holochain development "sandbox". A temporary directory on your file system that will store all your keys and data for the hREA happ that you are about to install and run.
network quic is there to instruct holochain to use a specific kind of networking, known as quic.echo \"pass\" | hc sandbox --piped create -n 1 -d hrea_tester network quic
Install the hREA hApp to your holochain sandbox. Make sure you use the right path to wherever on your filesystem you have
hrea_suite.happ file that you downloaded.echo \"pass\" | hc sandbox --piped call install-app ./hrea_suite.happ
Start your holochain "sandbox" runtime, attaching ports for admin level websocket server on port 4001 and for an app level websocket server on port 4000.
echo \"pass\" | hc sandbox --piped -f=4001 run --all --ports 4000
You can safely stop and restart this particular process, and don't have to rerun the other steps. This is the process that you must have running in order to develop a user interface or service with an hREA backend.
