I have a requirement where the product needs to implement undo-redo functionality.
Currently I hold a huge Object which comes from a single mongo collection.
Pseudo structure:
{
cart:{
products:[
{
name: "Watch",
quantity: 1,
shippingDate: 123456782,
text: "lorem ipsum....",
prices:[
{
currency: "USD",
price: 300
},
{
currency: "GBP",
price: 220
}
]
}
],
...someMoreKeyValuePair
}
}
Now the update can happen on any node, eg: product getting added/modified/removed, cart level data getting added/modified/removed.
And the structure is huge, now how do I maintain undo-redo actions on any change happening on the entire structure.
What data-structure or design pattern should I read to get a better approach on solving this.
