 # felles-openapi-customizer-lib
-felles-openapi-customizer-lib eies og forvaltes av team-rettighet
+
+Takes an OpenAPI specification and customizes all paths with the standard
+security scheme and headers typically used in SPK.
+
+These headers are normally omitted from the OpenAPI specification for
+practical purposes and provided to the client and consumed by the server
+using implicit infrastructure libraries such as `felles-outbound-lib`. This
+class allows adding these headers back in, in order for the server to show a
+complete specification using SwaggerUI.
+
+There are two standard security schemes typically supported in SPK:
+
+1. Token based authentication using a security token.
+2. Basic authentication using the employee's username and password.
+
+There are three standard headers supported in SPK:
+
+1. `X-Application-Id` which contains the caller's application identity.
+2. `X-Correlation-Id` which correlates the invocation across systems.
+3. `X-Request-Origin` which contains the origin's application identity.
+
+## Usage
+
+### Maven
+
+Add the following dependency to your project:
+
+```xml
+<!-- add this to your pom.xml -->
+<dependency>
+    <groupId>no.spk.felles</groupId>
+    <artifactId>felles-openapi-customizer-lib</artifactId>
+    <version>0.0.1-SNAPSHOT</version>
+</dependency>
+```
+
+### Customize an existing OpenAPI-spec (contract-first)
+
+Takes the filename of an OpenAPI specification on classpath as input,
+reads the file, customizes it with the given security schemes and
+headers, and returns it as an `OpenAPI` object.
+
+The `OpenAPI` object can be provided to Spring as a `@Bean` in order for
+documentation providers such as Springdoc to show the specification on
+the server using SwaggerUI.
+
+```kotlin
+@Bean
+fun createOpenAPI() {
+    val customizer = OpenAPICustomizer(
+        customizeWithSecuritySchemes = true,
+        customizeWithStandardHeaders = true,
+    )
+    return customizer.readAndCustomizeOpenAPI("/openapi/openapi.yaml")
+}
+```
+
+Note that the above requires the OpenAPI specification to be unpacked
+into `/openapi/openapi.yaml` on the classpath.
+
+This is well-suited for OpenAPI specifications written contract-first,
+where the specification is available as a file.
+
+If using Springdoc, it is also advisable to disable scanning of packages
+adding `springdoc.packages-to-scan=none` to Spring Boot's configuration,
+otherwise annotated resources might show up twice in the specification.
+
+### Customize a generated OpenAPI-spec (code-first)
+
+Customizes an existing OpenAPI specification with the given security
+schemes and headers.
+
+The `OpenAPI` object can be provided to Spring as a `@Bean` in order for
+documentation providers such as Springdoc to show the specification on
+the server using SwaggerUI.
+
+```kotlin
+@Bean
+fun createOpenAPI() {
+    val customizer = OpenAPICustomizer(
+        customizeWithSecuritySchemes = true,
+        customizeWithStandardHeaders = true,
+    )
+    val generatedOpenAPI = OpenAPI()
+    return customizer.customizeOpenAPI(generatedOpenAPI)
+}
+```
+
+This is well-suited for OpenAPI specifications that are generated from
+annotated source code, after which these customizations are applied.
+
