nuts-node #########

Distributed registry for storing and querying health care providers their vendors and technical endpoints.

See the documentation <https://nuts-node.readthedocs.io/en/latest/>_ for how to set up, integrate and use the Nuts node.

Hello, World! ^^^^^^^^^^^^^

The simplest way to spin up the Nuts stack is by using the setup provided by nuts-network-local <https://github.com/nuts-foundation/nuts-network-local>_. The setup is meant for development purposes and starts a Nuts node, "Demo EHR", "Registry Admin Demo" for administering your vendor and care organizations and a HAPI server to exchange FHIR data.

To get started, clone the repository and run the following commands to start the stack:

.. code-block:: shell

cd single
docker compose pull
docker compose up

After the services have started you can try the following endpoints:

  • Nuts Node status page <http://localhost:1323/status/diagnostics/>_.
  • Registry Admin Demo login <http://localhost:1304/>_ (default password: "demo").
  • Demo EHR login <http://localhost:1303/>_ (default password: "demo").

Development ^^^^^^^^^^^

Go >= 1.18 is required.

Building


Just use go build.

Building for exotic environments

You can build and run the Nuts node on more exotic environments, e.g. Raspberry Pis:

  • 32-bit ARMv6 (Raspberry Pi Zero): env GOOS=linux GOARCH=arm GOARM=6 go build

Running tests


Tests can be run by executing

.. code-block:: shell

go test ./...

Code Generation


Code generation is used for generating mocks, OpenAPI client- and servers, and gRPC services. Make sure that GOPATH/bin is available on PATH and that the dependencies are installed

Install protoc:

| MacOS: brew install protobuf | Linux: apt install -y protobuf-compiler

Install Go tools:

.. code-block:: shell

make install-tools

Generating code:

To regenerate all code run the run-generators target from the makefile or use one of the following for a specific group

================ ======================= Group Command ================ ======================= Mocks make gen-mocks OpenApi make gen-api Protobuf + gRCP make gen-protobuf All make run-generators ================ =======================

Docs Generation


To generate the documentation, you'll need python3, sphinx and a bunch of other stuff. After you have installed python3 (and pip3 if this not already installed) run

.. code-block:: shell

pip3 install -r docs/requirements.txt

README

The readme is auto-generated from a template and uses the documentation to fill in the blanks.

.. code-block:: shell

make gen-readme

Documentation

The documentation can be build by running the following command from the /docs directory:

.. code-block:: shell

make html

Configuration ^^^^^^^^^^^^^

The Nuts node can be configured using a YAML configuration file, environment variables and commandline params.

The parameters follow the following convention: $ nuts --parameter X is equal to $ NUTS_PARAMETER=X nuts is equal to parameter: X in a yaml file.

Or for this piece of yaml

.. code-block:: yaml

nested:
    parameter: X

is equal to $ nuts --nested.parameter X is equal to $ NUTS_NESTED_PARAMETER=X nuts

Config parameters for engines are prepended by the engine.ConfigKey by default (configurable):

.. code-block:: yaml

engine:
    nested:
        parameter: X

is equal to $ nuts --engine.nested.parameter X is equal to $ NUTS_ENGINE_NESTED_PARAMETER=X nuts

While most options are a single value, some are represented as a list (indicated with the square brackets in the table below). To provide multiple values through flags or environment variables you can separate them with a comma (,).

Ordering


Command line parameters have the highest priority, then environment variables, then parameters from the configfile and lastly defaults. The location of the configfile is determined by the environment variable NUTS_CONFIGFILE or the commandline parameter --configfile. If both are missing the default location ./nuts.yaml is used.

Server options


The following options can be configured on the server:

.. marker-for-config-options

It is used to identify the node on the network.

This table is automatically generated using the configuration flags in the core and engines. When they're changed the options table must be regenerated using the Makefile:

.. code-block:: shell

$ make update-docs

CLI options ^^^^^^^^^^^

The following options can be supplied when running CLI commands:

======= ============== ===================================================================================================================================================================== Key Default Description ======= ============== ===================================================================================================================================================================== address localhost:1323 Address of the remote node. Must contain at least host and port, URL scheme may be omitted. In that case it 'http://' is prepended. timeout 10s Client time-out when performing remote operations, such as '500ms' or '10s'. Refer to Golang's 'time.Duration' syntax for a more elaborate description of the syntax. ======= ============== =====================================================================================================================================================================
