Node zosconnect

A wrapper service for z/OS® Connect EE, enabling node applications to discover and access zSystems resources that are service enabled by z/OS® Connect. Version 2 of this module pre-reqs z/OS Connect EE V3.0.8 or later.

Services and APIs are identified by name that is unique within the scope of the target z/OS® Connect instance (or cluster). The node application uses pre-existing knowledge of the service or API name, or discovers it dynamically by retrieving a list of available services or APIs. The z/OS® Connect node wrapper provides access to JSON request and response schemas for the specific z/OS® Connect service and the Swagger document for APIs, enabling the node application to invoke that service and process the response.

Installing

npm install zosconnect-node

Usage

Connecting to z/OS Connect

var ZosConnect = require('zosconnect-node');
var options = {
  uri:'http://mainframe:8080'
}
var zosconnect = new ZosConnect(options);

The options object matches exactly the options described by the request/request module. The uri or url parameter must be specified.

HTTPs Support

Create the options object with locations for the CA certificate file and optionally the client certificate and client private key (if using client authentication). If the strictSSL option is set to false then invalid SSL certificates can be used which may be of use in development environments.

var fs = require('fs');
var path = require('path');
var caFile = path.resolve(__dirname, 'ca.pem');
var certFile = path.resolve(__dirname, 'cert.pem');
var keyFile = path.resolve(__dirname, 'key.pem');
var options = {
  uri:'https://mainframe:9443',
  ca: fs.readFileSync(caFile),
  cert: fs.readFileSync(certFile),
  key: fs.readFileSync(keyFile),
  passphrase: 'passw0rd',
  strictSSL: true
}

Basic Authentication

Add the authentication credentials to the options object.

var options = {
  uri: 'http://mainframe:9080',
  auth: {
    user: 'userId',
    pass: 'password'
  }
}

APIs

Retrieve a list of APIs

zosconnect.getApis().then(console.log);

Get an API

zosconnect.getApi('healthApi').then(console.log);

Create an API

zosconnect.createApi(fs.readFileSync('api.aar')).then(console.log);

Call an API

zosconnect.getApi('healthApi').then((api) => {
  api.invoke('patient/12345', 'GET', null).then((response) => {
    if(response.statusCode != 200) {
      console.log('Invoke failed with respCode = ' + response.statusCode);
    } else {
      console.log(response.body);
    }
  }).catch(console.log);
});

Get the Swagger document for an API

zosconnect.getApi('healthApi').then((api) => {
  api.getApiDoc('swagger').then(console.log);
});

Start or Stop an API

zosconnect.getApi('healthApi', function(error, api){
  api.stop().catch(console.log);
  api.start().catch(console.log);
})

Update an API

zosconnect.getApi('healthApi').then((api) => {
  api.update(fs.readFileSync('healthApi.aar')).catch(console.log);
});

Delete an API

zosconnect.getApi('healthApi').then((api) => {
  api.delete().catch(console.log);
})

Services

Retrieve a list of services

zosconnect.getServices().then(console.log);

Create a Service

zosconnect.createService(fs.readFileSync('dateTimeService.sar')).then(console.log);

Get a service

zosconnect.getService('dateTimeService').then(console.log);
//normally this would then go on and work with the service

Invoke a service

zosconnect.getService('dateTimeService').then((service) => {
  service.invoke({input:'data'}).then((response) => {
    if(response.statusCode != 200) {
      console.log('Invoke failed with respCode = ' + response.statusCode);
    } else {
      console.log(response.body);
    }
  }).catch(console.log);
});

Get the request schema

zosconnect.getService('dateTimeService').then((service) => {
  service.getRequestSchema().then(console.log).catch(console.log);
});

Get the response schema

zosconnect.getService('dateTimeService').then((service) => {
  service.getResponseSchema().then(console.log).catch(console.log);;
});

Update a Service

zosconnect.getService('dateTimeService').then((service) => {
  service.update(fs.readFileSync('dateTimeService.sar')).catch(console.log);
});

Delete a Service

zosconnect.getService('dateTimeService').then((service) => {
  service.delete().catch(console.log);
})
