Flow v5.1

This minor update of Total.js Flow brings a few great features and small UI improvements. Just download Flow package and update your project.

Applying changes

VERY IMPORTANT CHANGE: Applying changes in flow designer is now done in much more efficient way. Instead of sending all the flows at once only changes are sent to the server. This also means the server doesn't need to proccess all the flows but only process the changes. Great work done by Martin Smola.

Enable / Disable IO

Martin Smola also added this missing and very helpful feature which you are gonna love. Now you can very simply enable/disable any input and output of all the components.

Input/Output enable/disable


Icons (Font-Awesome) are parts of designer and they are defined in components.

Pause Flow

This version supports pausing of the entire Flow processing.

Pause Flow


Variables form contains a better input field / codemirror with Total.js config syntax highlighter. It's much nicer and cleaner than before, example:

Flow variables


This version brings a simple logging of events into a plain text file. By default it's disabled but enabling is very easy, just edit config file as shown bellow:

package#flow       (Object)  : { logging: true }

Example of output:

Tab change indicator

In this version Flow indicates a change in tabs. Now you can see which tabs were changed.

New version of jComponent (UI components)

New version of jComponent brings new hidden features which will create Total.js Flow better than ever before. All forms like Components, Export, Import, etc. are loaded dynamically just like they used to but now they will be removed when they are inactive for more than 5 minutes. Another feature is called LAZY components which inits/loads components like Calendar, SnackBar, Confirm, etc. when the component is required. This feature saves memory and CPU consumption of your device.

It's easy, just set e.g. `res.status = 404`.
