AutoblocksPromptManager

Below are the arguments that can be passed when initializing the prompt manager:

namerequireddefaultdescription
appNametrueThe name of the app that contains the prompt.
idtrueThe ID of the prompt.
version.majortrueMust be pinned to a specific major version.
version.minortrueCan be one of: a specific minor version or the string "latest".
apiKeyfalseAUTOBLOCKS_API_KEY environment variableYour Autoblocks API key.
refreshIntervalfalse{ seconds: 10 }How often to refresh the latest prompt. Only relevant if the minor version is set to "latest".
refreshTimeoutfalse{ seconds: 30 }How long to wait for the latest prompt to refresh before timing out. A refresh timeout will not throw an uncaught error. An error will be logged and the background refresh process will continue to run at its configured interval.
initTimeoutfalse{ seconds: 30 }How long to wait for the prompt manager to be ready (when calling init()) before timing out.
import { AutoblocksPromptManager } from '@autoblocks/client/prompts';

const mgr = new AutoblocksPromptManager({
  appName: 'my-app',
  id: 'text-summarization',
  version: {
    major: '1',
    minor: '0',
  },
});

​
exec

Starts a prompt execution context by creating a new PromptExecutionContext instance.

const response = await mgr.exec(async ({ prompt }) => {
  ...
});

​
PromptExecutionContext

An instance of this class is created every time a new execution context is started with the exec function. It contains a frozen copy of the prompt manager’s in-memory prompt at the time exec was called. This ensures the prompt is stable for the duration of an execution, even if the in-memory prompt on the manager instance is refreshed mid-execution.

​
params

An object with the prompt’s parameters.

const response = await mgr.exec(async ({ prompt }) => {
  const params: ChatCompletionCreateParamsNonStreaming = {
    model: prompt.params.model,
    temperature: prompt.params.temperature,
    ...
  };
});

​
renderTemplate

The renderTemplate function accepts a template ID and parameters and returns the rendered template as a string.

namerequireddescription
templatetrueThe ID of the template to render.
paramstrueThe parameters to pass to the template. These values are used to replace the template parameters wrapped in double curly braces.
const response = await mgr.exec(async ({ prompt }) => {
  // Use `prompt.renderTemplate` to render a template
  console.log(prompt.renderTemplate(
    {
      template: 'util/language',
      params: {
        // Replaces "{{ language }}" with "Spanish"
        language: 'Spanish',
      },
    },
  ));
  // Logs "Always respond in Spanish."
});

​
renderTool

The renderTool function accepts a tool name and parameters and returns the rendered tool as an object in the JSON schema format that OpenAI expects.

namerequireddescription
tooltrueThe name of the tool to render.
paramstrueThe parameters to pass to the tool. These values are used to replace the tool parameters wrapped in double curly braces.
const response = await mgr.exec(async ({ prompt }) => {
  // Use `prompt.renderTool` to render a tool
  console.log(prompt.renderTool(
    {
      tool: 'MyTool',
      params: {
        // Replaces "{{ language }}" with "Spanish"
        language: 'Spanish',
      },
    },
  ));
});
