Omnis_JSnode_Zip

Omnis Studio 10.22 Demo interface to the JS worker using Node jszip functions.

JavaScript Worker Object

The JavaScript Worker Object allows you to execute JavaScript methods inside node.js by making the request in Omnis code by calling a Worker Object method, and receiving the results via a worker callback.

Adding ZIP support

To add support for ZIP files. To do this, install the node.js jszip module by running the npm command in the jsworker folder:

npm i jszip
(the npm command is installed with node.js, available on the web)

Edit omnis_modules.js by adding an entry to the 'moduleMap' object for the zip module:

const moduleMap = {
zip: require('./omnis_zip.js'),
... // Other modules
};

Once the above has been installed, then the demo library will work for you.

This library is demo bringing all the methodMapClass function calls specified within omnis_zip.js into an Omnis object.
