"Google Labs Breadboard" Useful nodes by Paul Kinlan Kit

This is a collection of Breadboard nodes that are helpful for building LLM-based (Generative AI) applications.

Installing

This Kit requires Node version >=v19.0.0. To install:

npm install @paulkinlan/breadboard-utils-kit

Node Types

Here are all node handlers that are included in the OpenAI Breadboard Kit

The undefinedGuard node

Takes an input and if the value is defined (!undefined) then outputs the input on the false. If the value is undefined outputs true on "true"

Inputs:

• input optional. The value to be checked if undefined.

Outputs:

• true - "true" if the input is undefined.
• false - value of the input if the input is not undefined.

The headTail node

Takes a list as input and returns the first item as the head, and the rest of the list as tail.

Inputs:

• input optional. The array to split in to 1 head and the remaining nodes.

Outputs:

• head - the first item in the list
• tail - the rest of the input list (slice(1))

Example graph

%%{init: 'themeVariables': { 'fontFamily': 'Fira Code, monospace' }}%%
graph TD;
inputprompt[/"input
id='input-prompt'"/]:::input -- "input->input" --> headTail1["headTail
id='headTail-1'"]
headTail1["headTail
id='headTail-1'"] -- "tail->input" --> undefinedGuard1["undefinedGuard
id='undefinedGuard-1'"]
headTail1["headTail
id='headTail-1'"] -- "head->text" --> output{{"output
id='output'"}}:::output
undefinedGuard1["undefinedGuard
id='undefinedGuard-1'"] -- "false->input" --> headTail1["headTail
id='headTail-1'"]
messageinputprompt[message]:::config -- "message->message" --o inputprompt
classDef default stroke:#ffab40,fill:#fff2ccff,color:#000
classDef input stroke:#3c78d8,fill:#c9daf8ff,color:#000
classDef output stroke:#38761d,fill:#b6d7a8ff,color:#000
classDef passthrough stroke:#a64d79,fill:#ead1dcff,color:#000
classDef slot stroke:#a64d79,fill:#ead1dcff,color:#000
classDef config stroke:#a64d79,fill:#ead1dcff,color:#000
classDef secrets stroke:#db4437,fill:#f4cccc,color:#000
classDef slotted stroke:#a64d79

Which will output [ { text: 1 }, { text: 2 }, { text: 3 }, { text: 4 } ]

The take node

Takes a list as input and returns the first count items.

Inputs:

• input required, the array to have count items taken from it.
• count required, the number of items to take from the input array.

Outputs:

• output - the first count items in the list

The take node

Takes a list as input and removes the first count items.

Inputs:

• input required, the array to have count items taken from it.
• count required, the number of items to take from the input array.

Outputs:

• output - length - count items in the list, starting at count
