# Notes
We need three major components to work together. I would love it if the node-store and the runtime are super loosely coupled so that they could be replaced by at will. So for example i could use the “server-runtime” that executes the node-graph on the server, or the “local” runtime that executes the node-graph locally.
**NODE_INTERFACE**
This is where the user interacts with the node graph. The frontend loads a node-system. Then fetches all the relevant nodes from the node-store.
**NODE_REGISTRY**
The node-store stores all the nodes. For each node it stores a definition and the wasm blob that executes that node.
**[[Projects/bachelor/RUNTIME_EXECUTOR|RUNTIME_EXECUTOR]]**
The runtime gets a node-graph and returns the result after executing the node-graph. It fetches the relevant nodes from the node-store.
# How to store nodes in the registry?
The nodes need:
## ID: string/string/string
I could imagine something like jimfx/nature/branch
## INPUTS:
We need a way to define how the UI should render the input ui. Could be something like:
```json
{
"inputs": [
“a”: {
“type”: “select”,
“options”: [
“curly”,
“straight”
]
},
"b": {
"type":"float",
"value": 0.5,
"max": 10.0,
"min": 0
},
"res":{
"type": "integer",
"value": 5,
"setting":"leaves/resolution"
}
]
}
```
## OUTPUTS
The nodes output, could look something like this:
```json
{
"outputs": ["stem","float"]
}
```
# How to store serialized nodes
```json
{
"id":"jimfx/nature/branch",
"inputs": [0,8.4],
"position": [0.6, 10]
"meta": {
"title":"Branch Node"
}
}
```

# RUNTIME_EXECUTOR
This component receives a serialized node_graph and returns the output. I generally love the idea that a node is a pure function which just receives its own inputs and then calculates them. BUT! there is always a but, there are some things that the nodes needs that are not its own inputs. These are in my experience:
**run_seed**
Some nodes generate random values, and to generate random values we generally need a seed value.
**settings**
There are some values that are kind-of global inputs. That means they are inputs to the node, but each node receives the same input. For example for the plant nodes, they are the resolution of each leave.
After some thinking, my idea is to model these inputs as *hidden* inputs to the node. So they are not gonna be visible in the **NODE_INTERFACE**.
But they are gonna be passed to the nodes as normal inputs. This could be super useful to allow easy memoization of the nodes, because if none of the inputs changed, we can return the previously computed output.
## Linking/Importing of Nodes
**WebAssembly Components**
\- only works in wasmtime / jco at the moment
For this the runtime_executor needs to be wasm aswell.
**No linking**
\+ Very easy to implement, works everywhere
\- Probably not as fast as components

# Rust Notes
## Options
So options are things that maybe contain values.
```rust
let option_a: Option<u8> = Some(8);
let option_b: Option<u8> = None;
```
To get at the value of a Options you have a few options;
```rust
let res:u8 = option_a.unwrap(); // using option.unwrap -> panics if value is none
if let Some(unwrapped1) = option_a {
println!("Unwrapped1 {}", unwrapped1);
}else {
println!("None Unwrapped1");
}
match option_a {
None => println!("None Unwrapped"),
Some(unwrapped1) => {
println!("Unwrapped1 {}", unwrapped1)
},
}
```
