Zowe API Mediation Layer

API Mediation Layer

Build Status

The home of Zowe API Mediation Layer

Prerequisites

Following platform is required to run the API Mediation Layer:

• Oracle or IBM Java SE Development Kit 8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html or https://www.ibm.com/developerworks/java/jdk/), Java 10 is not supported

Other development prerequisites

Following tools are required to build and develop API Mediation Layer:

• Node.js and npm are required to be installed globally to be able to build the API Catalog UI

Quick start

1. Install the package manager pnpm globally in order to build the project:

   npm add -g pnpm

2. Install npm packages for the UI:

   cd api-catalog-ui/frontend/; pnpm install; cd ../..

3. Install concurrently globally:

   npm install -g concurrently

4. Build all modules:

   ./gradlew build

5. Run all service on local machine:

   npm run api-layer

Authentication service

The API Mediation Layer uses a dummy authentication provides as a default security provider for the development purposes. To log in, use user as username and password.

(Optional) z/OSMF Authentication

Perform the following steps to use the real authentication service:

1. Configure a valid z/OSMF instance using the following sample configuration config/local/api-defs/zosmf-sample.yml.

2. Modify gateway-service.yml with a z/OSMF configuration

apiml:
    security:
        auth:
            provider: zosmf
            zosmfServiceId: zosmfId  # Replace me with the z/OSMF service id

Ensure that the z/OSMF certificate is trusted by APIML. You have two options:

1. Import the certificate to the APIML keystore using scripts/apiml_cm.sh --action trust as described at Trust certificates of other services The apiml_cm.sh script has been moved to zowe-install-packaging repository

2. Disable certificate validation. For more information, see Disabling certificate validation on localhost

Run unit tests

Unit tests for Java and TypeScript modules are executed as a part of the build process.

Measure code coverage

For the code coverage of all modules, run:

    ./gradlew coverage

The code coverage for new code should be higher that 60% and should not be decreased for existing code.

The reports in HTML format are stored build/reports/jacoco/test/html/index.html for each Java module.

For the code coverage of a single Java module (for example discovery-service), run:

    ./gradlew :discovery-service:jacocoTestReport

You can an individual test class by:

    ./gradlew :discovery-service:test --tests org.zowe.apiml.discovery.staticdef.ServiceDefinitionProcessorTest

Run integration tests

Follow the instructions in Integration Tests to run integration tests.

Security

For more information about how the certificates between APIML services are setup, see TLS Certificates for localhost.

Contributor guidelines

Follow the guidelines in Contributing to add new functionality.

Local configuration of services

Follow the guidelines in Local Configuration to set local environment properties for testing on your local machine include HTTPS setup.

Also if you use IntelliJ IDEA, see learn how to configure Run Dashboard to use these local configurations.

If you use Visual Studio Code, see how to configure it to develop and debug local configurations.

Adding services that does not support API Mediation Layer natively

See Adding Services to API Gateway without Code Changes.

API Catalog UI

For more information about the UI of the Catalog see its README.
