Node-based

BP is based on nodes. Node is a simple function that accepts set of streams and returns set of stream. Someone calls it "pipe".

Define your node

To make bp know what is you node you should provide a descriptor of you node's sources, sinks and function. Source and sinks are descriptors of you input and output stream types. Function is you node's function exactly. It should accept

BP Result

In result you have generated stream-pipe application like:

const node1Result = node1({});

const node2Source = {streamName: node1Result.name};
const node2Result = node2(node2Source);

There are no helping streams or such a thing. Minimal overhead.

Design

• Add node to scene
• Convert descriptor to node
• Validate lines (check that needed ports existed and remove line if not)
• Remove node from scene
• Move node (ui)
• Connect ports if possible
  • check set of rules like maxLineNumber, same group etc
• Add port if possible
• Remove port if possible
