Mainframe APIs with HostBridge JavaScript
IBM z Systems* mainframes are a trove of application and
data assets. Organizations needing to deploy these assets
as RESTful APIs can turn to mainframe-based HostBridge
with its JavaScript*/JSON engine.

D

iscussing ways to improve mobile
app development, an industry
analyst recently recommended
that organizations consider lightweight
RESTful services as a fast, flexible
way to achieve mobile objectives and,
further, that they look into server-side
JavaScript, particularly Node.js, as their
development technology.
We wholeheartedly agree, and we'd
extend the recommendations to two
broader considerations. First, mobile app
development is only one area where the
recommendations are relevant. Using
JavaScript to integrate disparate systems-
enterprise applications, web, mobile, cloud,
SOA, etc.-is a proven approach that has
delivered value for years. And it promises
to do so for years to come, thanks to the
emergent API economy.
Second, organizations that rely on IBM
z Systems mainframes have long been able
to implement server-side JavaScript on the
mainframe-with HostBridge Technology's
JavaScript Engine (HB.js). Think of it as
the (slightly older) Node.js cousin for the
mainframe. We might be biased, but
we believe JavaScript/JSON is the ideal

technology for bringing the mainframe into
the API economy.
Designed specifically for z Systems,
HB.js is an excellent choice for creating
standards-based RESTful APIs from
the widest range of mainframe assets-
databases, COMMAREA programs and
terminal-oriented applications. Uniquely,
HB.js automates even the most complex
CICS* micro-flows as a single, efficient,
low-overhead, high-performance API.
Here's an example. A financial institution
reliant on a terminal-oriented CICS banking
application saw obvious benefits in creating
APIs based on this application, starting with
an account overview API. Built with HB.js,
the API lets users submit a single request
to HB.js, which then navigates dozens of
CICS screens and orchestrates/aggregates
all relevant fields and data in a single
response. Developers incorporated this API
into their mobile banking app and provided
it internally to employees. In just this way,
legacy CICS apps take their rightful place in
the API economy.
HB.js offers all of the benefits of serverside JavaScript: standards-based data
exchange with web and mobile apps, plus

enterprise-level functionality, performance
and scalability. JavaScript is one of the
most widely used languages on the planet,
so developers in-house are likely to know it
already. COBOL programmers tell us that
learning a powerful, flexible new language
makes work fun again. And increased
productivity means faster deployment of new
APIs and services.
Whatever your mainframe integration
objectives-making assets available via web
or mobile apps, creating standards-based
mainframe web services for your SOA, or
creating new, open APIs for employees,
partners, and customers-HB.js offers the
power and agility to achieve them.
