A sample node js api for finding cars and accounts for a dealership,its used here to demonstrate the steps to extend API/ML with your own rest api.


Only rest api with https support can be deployed behind API/ML, make sure to enable https support in your rest api.
This sample express app, has https enabled already.

PART I: Download & Build on local

Method 1: From github

1) Clone the repository, install node packages and verify routes locally

//on local
git clone
cd sample-node-api
npm install
npm start

Open your local browser and verify the sample-node-api is working by accessing:

2) Transfer project files from local to remote host

The node_modules folder will not be transferred, we can do npm install later on remote server itself to pull down required node packages

cd sample-node-api
npm run build
scp -r dist</usr/lpp/extender>/sample-node-api

For the next step, ensure that you have node installed on z/OS and your PATH includes nodejs/bin directory.

. ~/.profile - (Skip if you can already run "npm" on z/OS)
cd </usr/lpp/extender>/sample-node-api
npm install

Method 2: From Artifactory

1) Download latest pax from artifactory

Get latest package from artifactory

Choose the latest pax build provided from the link above and download it into your local storage.

2) Transfer and unpax on z/OS

put <pax-name>.pax

PART II: Deploy with Zowe on server

1) login


2) install component using script

./<zowe-runtime-dir>/bin/ -d <zowe-extensions-dir> -i <zowe-instance-dir> -o <component-file-path> -l <log-folder>
<zowe-extensions-dir> - Directory that will hold all external extensions installed onto zowe
<zowe-instance-dir> - Current installed Zowe's instance directory
<component-file-path> - The path to the component being installed (the component file transferred from local to z/OS in PART I)
<log-file> - Directory that will hold the logs of the component installation

3) Lifecycle scripts of the component

We expect following in service folder In our case its bin folder with relevant scripts. starts node app on configured port its custom script use to configure port for our node app, feel free to use your desired way

4) Access newly deployed webservice

Please see static definition file sample-node-api.yml
It configures service endpoint as sample-node-api with property serviceId
We also provide api gateway base path api\v1 with property gatewayUrl in same file.

In effect, service can be accessed with following url:

where GATEWAY_PORT is configured in $INSTANCE_DIR/instance.env

Verify by accessing following:

5) Registered With API Catalog
