# identity-service-api

![Build](https://github.com/NHSDigital/identity-service-api/workflows/Build/badge.svg?branch=master)

This is a RESTful HL7® FHIR® API specification for the *Identity Service API*.

* `specification/` This [Open API Specification](https://swagger.io/docs/specification/about/) describes the endpoints, methods and messages exchanged by the API. Use it to generate interactive documentation; the contract between the API and its consumers.
* `scripts/` Utilities helpful to developers of this specification.
* `proxies/` The Apigee API Proxy

Consumers of the API will find developer documentation on the [NHS Digital Developer Hub](https://emea-demo8-nhsdportal.apigee.io/).

## Development

### Requirements
* make
* nodejs + npm/yarn
* [poetry](https://github.com/python-poetry/poetry)

### Install
To setup
```
$ make install
```

### Environment Variables
Various scripts and commands rely on environment variables being set. These are documented with the commands.

:bulb: Consider using [direnv](https://direnv.net/) to manage your environment variables during development and maintaining your own `.envrc` file - the values of these variables will be specific to you and/or sensitive.

### Make commands
There are `make` commands that alias some of this functionality:
* `lint` -- Lints the spec and code
* `publish` -- Outputs the specification as a **single file** into the `build/` directory
* `serve` -- Serves a preview of the specification in human-readable format

### Running tests
For detailed instructions see `/e2e`.

### VS Code Plugins

* [openapi-lint](https://marketplace.visualstudio.com/items?itemName=mermade.openapi-lint) resolves links and validates entire spec with the 'OpenAPI Resolve and Validate' command
* [OpenAPI (Swagger) Editor](https://marketplace.visualstudio.com/items?itemName=42Crunch.vscode-openapi) provides sidebar navigation

### Emacs Plugins

* [**openapi-yaml-mode**](https://github.com/esc-emacs/openapi-yaml-mode) provides syntax highlighting, completion, and path help

### Speccy

> [Speccy](http://speccy.io/) *A handy toolkit for OpenAPI, with a linter to enforce quality rules, documentation rendering, and resolution.*

Speccy does the lifting for the following npm scripts:

* `test` -- Lints the definition
* `publish` -- Outputs the specification as a **single file** into the `build/` directory
* `serve` -- Serves a preview of the specification in human-readable format

(Workflow detailed in a [post](https://developerjack.com/blog/2018/maintaining-large-design-first-api-specs/) on the *developerjack* blog.)

:bulb: The `publish` command is useful when uploading to Apigee which requires the spec as a single file.

### Caveats

#### Swagger UI
Swagger UI unfortunately doesn't correctly render `$ref`s in examples, so use `speccy serve` instead.

### Platform setup

Successful deployment of the API Proxy requires:

1. A *Key-Value Map* named identity_service_variables
2. An encrypted *Key-Value Map* named identity-service-variables-encrypted

The Key-Value maps need to be specified within the [api-management-infrastructure repository](https://github.com/NHSDigital/api-management-infrastructure) to be able to be used with the API proxy.
:bulb: For Sandbox-running environments (`test`) these need to be present for successful deployment but can be set to empty/dummy values.
