Meteor

This library is universal: outside of environment-specific features (parsing DOM tables in the browser, streaming write in nodejs), the core is ES3/ES5 and can be used in any reasonably compliant JS implementation. It should play nice with meteor out of the box.

This demonstration

You can split the work between the client and server side as you see fit. The obvious extremes of pure-client code and pure-server code are straightforward. This demo tries to split the work to demonstrate that the workbook object can be passed on the wire.

The read demo:

• accepts files from the client side
• sends binary string to server
• processes data on server side
• sends workbook object to client
• renders HTML and adds to a DOM element

The write demo:

• generates workbook on server side
• sends workbook object to client
• generates file on client side
• triggers a download.

This demo uses the FileSaver.js library for writing files, installed through the pfafman:filesaver wrapper:

meteor add pfafman:filesaver

Setup

This tree does not include the .meteor structure. Rebuild the project with:

meteor create .
npm install babel-runtime meteor-node-stubs xlsx
meteor add pfafman:filesaver
meteor

Environment-specific features

File-related operations (e.g. XLSX.readFile and XLSX.writeFile) will not be available in client-side code. If you need to read a local file from the client, use a file input or drag-and-drop.

Browser-specific operations (e.g. XLSX.utils.table_to_book) are limited to client side code. You should never have to read from DOM elements on the server side, but you can use a third-party virtual DOM to provide the required API.
