Node SDK

Node 18+. Uses the built-in fetch; WebSocket hot-reload is powered by ws, its only dependency. Source lives in sdk/node.

Usage

import { PromptOpsClient } from '@promptops/client'

const client = new PromptOpsClient({
  server: 'http://localhost:8080',
  namespace: 'prod',
  token: 'promptops-dev-token',
})

// Fetch a prompt by key (locally cached)
const prompt = await client.getPrompt('sql.generator')

// Render template variables
const text = await client.render('sql.generator', { question: 'list all users' })

// Subscribe to hot-reload: the cache refreshes when the prompt changes
client.on('update', (e) => console.log('hot-reloaded:', e.key))
client.watch()
