v1.1.3 New Version
- Server script - to run a Node script on the server, as a workflow step.
This will be handy if you don’t want to create a plugin of your own for server side code.
Uses
-
Calculations and string expressions, regular expressions.
-
Conversions between types, which has been difficult to do on the server side.
-
Set a value to be used by a subsequent workflow step.
I’ll be putting up some examples soon.
Note that you can run the script from a page workflow, the script will be run on the server, so you’ll notice a delay on the app as the client waits for the result.
Limitations
The script will be stopped with an error after a timeout of 10 seconds.
Global variables aren’t reliably available – you can set them up, but there’s no guarantee that the script will run in the same process when you want to retrieve them.
There are a limited number of Node packages/modules available, Bubble has mentioned they will come up with a process for more to be added.
Caution - if you allow untrusted scripts to run, for example submitted by a user, it could break your app’s server scripting environment, and require intervention by the Bubble team.
