Manage Variables Context Storage - austral-electronics/Austral_Support GitHub Wiki

• Storing variables
• Node-Red Context and Persisting Data
• Backing up and restoring global variables in Node Red

To erase a persistant context :

 context.set('contextName',undefined, 'storeInFile');

To initialise a persistant context :

 var cont = context.get('contextName', 'storeInFile');
 if (cont===undefined) {
    cont={};
    cont.myVariable=0;
    context.set('contextName',cont, 'storeInFile');
 }

The context is stored in a json file in ~/.node-red/context/ directory every 30s by default
