WebSockets look to be supported reasonably well in Cache. I have yet to use them in production so I am wondering how well it has worked for other developers.

In particular what happens when the browser does not support WebSockets, or when a firewall blocks the connection.

Have you had to write your own long polling fall-back?

I've read the documentation and found this interesting article...

I cannot connect to Cache from node.js  

I have installed in Windows 10 the following: CACHE 2016, node.js v 4.4.7 and  express .

-  where can I get cache.node? The link in the Intersystmes documentation  http://globalsdb.org/downloads/  doesn't work. I found cache0100.node and cache0120.node  in my Cache instance's  \bin directory. But I am not sure if I can use them or not.

 - how to install cache.node ? Where do I place it exactly? 

Can anyone recommend any tutorial or code example with installation instructions?

Does anyone know where to find a cache.node that works with Cache version 2016.1.1.108.0? I am currently getting  this:

Error: Unable to load shared library C:\InterSystems\TryCache\bin\cache.node''

I am using Windows 7 Pro + SP1.

Thanks!

HI,

I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.

1. It has to be Secure

2. It has to be fast

3. It has to be Non CSP / Non Zen

4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource

5. Version 2018 Ensemble

My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018

iris.node download

Hi,

I want to test the node.js interface to iris with trial sandbox. The node.js documentation refers to get de node package from the instance bin directory. As I'm trying to use the trial sandbox I don't have access to the directory. Please let me know where I could download iris.node package.

Thanks,

Fabian

Searching the developer community for the string "node.js" leads to navigating to the following URL: https://community.intersystems.com/search/all/node.js for which the browser receives the "404 NOT FOUND" error response. The behavior is consistent for any search string ending on ".js" or ".css" (not sure whether there any other suffixes affected). Please fix the DC to handle such search strings appropriately.

Node.js fails to open database

Hi,

My attempt to run a node.js command fails at the open command with a "Error loading Cache Library: C:/InterSystems/Cache2018/bin/cache.dll; Error Code 126 (The specified module could not be found.)" result. I can't argue with the error message as the cache.dll file doesn't exist. Apparently I missed an installation step. Could somebody point out what it might be please.
