Template Kit
This kit contains two nodes: promptTemplate and urlTemplate. Both are intended to facilitate the often-necessary string-munging when working with LLMs or accessing APIs.
The promptTemplate node
Use this node to populate simple handlebar-style templates. It takes a string template that can contain zero or more placeholders that will be replaced with values from inputs.
Specify placeholders in the handlebar-style in format -- like `` in the template. The placeholders in the template will pop up as input ports for the node, ready to be wired in. The node will replace all placeholders with values from the wired in input ports and pass the result along as output.
Input ports
The promptTemplate node has a variable number of input ports.
-
Template (id:
template) -- the template to fill out. Required. -
Placeholder input ports -- zero or more additional ports that will be used to replace placeholders in the template.
Output ports
The promptTemplate node has a single output:
- Prompt (id:
prompt) -- a string that contains the result of replacing placeholders in the Template with values from the placeholder input ports.
Example
If we set our Prompt to:
Question: {{question}}
Thought: {{thought}}
And then send "How old is planet Earth" to the question input port along with "I wonder how old planet Earth is?" to the thought input port, we will get this Result:
Question: How old is planet Earth?
Thought: I wonder how old planet Earth is?Tip
This example is captured in the board above.
Implementation:
The urlTemplate node
Use this node to safely construct URLs. It's similar in spirit to the promptTemplate node, except it ensures that the handlebar parameters are properly encoded as part of the URL. This node relies on the URI template specification to construct URLs, so the syntax is using single curly braces instead of double curly braces.
Input ports
The urlTemplate node has a variable number of input ports.
-
Template (id:
template) -- required, a template for the URL. It can contain zero or more placeholders that will be replaced with values from the input property bag. Specify placeholders as{propertyName}in the template. -
Placeholder input ports -- zero or more inputs that will be used to replace placeholders in the template.
Outputs ports
The urlTemplate node has a single output port.
urla string that contains the result of replacing placeholders in the template with values from the inputs.
Example
If we set the Template to:
https:/books/v1/volumes?q={query}&orderBy=relevanceAnd send "utopian sci-fi" to the query input, we will see this at the URL output:
https:/books/v1/volumes?q=utopian%20sci-fi&orderBy=relevance
