    :alt: GitHub go.mod Go version

|gover| or higher is required.

Building
********

Just use ``go build``.

ES256 Koblitz support
=====================

To enable ES256K (Koblitz) support, you need to build with the ``jwx_es256k`` tag:

.. code-block:: shell

    go build -tags jwx_es256k

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``
================ =======================

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
