HB.js

The HostBridge JavaScript Engine (HB.js) VS Code extension modernizes the way you interact with HB.js and offers a friendly and convenient way to work with HB.js Primitives, the Cobol CopyBook to Javascript object generation tool, and the Application Explorer.

How can we improve the HB.js VSCode Extension? Let us know on our Git repository

The extension includes the following features:

  • Execution of HB.js Primitives (Make/Put/Run)
  • Access to the Integrated Application Explorer
  • Native generation of a JavaScript object from a COBOL copybook

Table of Contents

Prerequisites

Ensure that you meet the following prerequisites before you use the HostBridge JavaScript Engine VS Code extension:

  • Access to HostBridge JavaScript Engine

Getting Started

Set a VS Code Workspace

The HB.js extension requires a VSCode Workspace for full functionality. To associate a folder with a workspace, open a folder in the Explorer view.

Set a Workspace

Add New Host Connection

To add a new host connection, click the + (plus) icon in the HB.JS: HOSTS window. A host connection requires the following information:

  • HB.js Host URL, including the port number. For example: http://example.com:9000
  • A Host Name and a Region Name to help you identify the connection in the Hosts window.
  • A Default User ID, which is a user ID already defined in CICS on the host. When you connect to the host, you'll be prompted to enter the password for this user ID.

Add New Host Connection

Select a Default Repository

Host > Region > [Right Click] Chosen Repository > Set Default Repository

Set Default Repository

Execute Primitives

  • Navigate to the HBJS Terminal, which shows HB.js command output and messages
  • Open a file in the explorer window ("right-click > Get" or double click a Host file)
  • Right-click in explorer window and select HB.js Commands > (Make|Put|Run) (there are also listed keyboard shortcuts for each)

Execute Primitive

Access the Integrated Application Explorer

To access the Application Explorer:

  • Click the Application Explorer icon next to the region where you want to run the Application Explorer.
  • In the Application Explorer tab, enter the transaction ID for the initial transaction that you want to analyze.

For information about using the Application Explorer, see Analyzing Applications in the HB.js documentation.

Application Explorer

Generate a JavaScript object from a COBOL copybook

  • Right-click on a COBOL file in the editor or in the explorer window and select HB.js Commands > Generate JS Object.
    Note: You can select either COBOL field names to use COBOL-style field names or JavaScript field names to use JavaScript-style field names in the generated file.

The generated HB.js JavaScript function is opened in the editor and saved to the workspace folder using a filename similar to filename_(COBOL|JavaScript)_JSOBJ.hbx

  • filename is the filename of the original COBOL file
  • (COBOL | JavaScript) indicates whether the HB.js function is created using COBOL-style or JavaScript-style field names for the object.

JS Object Generation

List of Limitations

The following features exist in the HB.js Eclipse plugin that have not yet been added to this extension.

  • Application Explorer Playback
  • Hex dump view
  • Worklog view
