VSKI SDK

The VSKI SDK is a runtime-agnostic client for interacting with the VSKI RocketBase platform. It supports standard database operations, realtime subscriptions, and provides a powerful engine for durable workflows.

Installation

Node.js / Bun (via GitHub)

This package can be installed directly from the GitHub repository.

Note: Ensure you are installing from a repository where this package is at the root, or use a tool that supports subdirectory installation.

# npm
npm install github:vski-ai/sdk

# bun
bun add github:vski-ai/sdk

Deno (via GitHub)

For Deno, you can import the exports.ts file directly via raw GitHub URL:

// Import from raw GitHub content
import { RocketBaseClient } from "https://raw.githubusercontent.com/vski-ai/sdk/main/exports.ts";

Or configure it in your deno.json imports:

{
  "imports": {
    "@vski/sdk": "https://raw.githubusercontent.com/vski-ai/sdk/main/exports.ts"
  }
}

Quick Start

import { RocketBaseClient } from "@vski/sdk";

const client = new RocketBaseClient("http://localhost:3001");

// Authenticate as Admin
await client.admins.authWithPassword("admin@example.com", "password123");

// Or as a regular user
await client.collection("users").authWithPassword(
  "user@example.com",
  "password123",
);

Database Operations

Collections & Records

const posts = client.collection("posts");

// Create a record
const record = await posts.create({
  title: "Hello World",
  content: "This is my first post",
  status: "draft",
});

// List records
const { items, totalItems } = await posts.getList(1, 30, {
  filter: 'status = "published"',
  expand: "author",
});

// Update
await posts.update(record.id, { status: "published" });

// Delete
await posts.delete(record.id);

// Bulk operations
await posts.bulkUpdate(["id1", "id2"], { status: "archived" });
await posts.bulkDelete(["id1", "id2"]);

Realtime Subscriptions

const unsubscribe = client.collection("messages").subscribe((event) => {
  console.log(event.action); // "create", "update", or "delete"
  console.log(event.record);
}, {/* optional: lastId, group */});

// Later
unsubscribe();

Durable Workflows

RocketBase supports "Code as Infrastructure" durable workflows. They survive restarts, handle retries automatically, and can wait for days for external signals.

1. Functional Style (Recommended)

import { step, workflow } from "@vski/sdk";

// Define reusable steps
const notifyUser = step("notify", async (email: string) => {
  // This logic is durable and retried on failure
  return await sendEmail(email, "Welcome!");
});

// Define the workflow
workflow("welcome-flow").run(async (ctx, email: string) => {
  await ctx.sleep("1h"); // Durable sleep
  await notifyUser(email);

  // Wait for an external signal (e.g. user clicking a link)
  const confirmation = await ctx.waitForSignal("user-confirm");
  return { confirmed: confirmation.success };
});

2. Class-Based Style (Decorators)

import { Step, Workflow, WorkflowBase } from "@vski/sdk";

@Workflow("order-process")
class OrderWorkflow extends WorkflowBase {
  @Step("payment", { retries: 3 })
  async processPayment(amount: number) {
    return await stripe.charge(amount);
  }

  async run(orderId: string, amount: number) {
    await this.processPayment(amount);
    await this.sleep("1d");
    // ...
  }
}

3. Running a Worker

Workers connect to RocketBase via WebSockets and execute the workflow logic.

import { WorkflowWorker } from "@vski/sdk";

const worker = new WorkflowWorker(client);
await worker.start("welcome-flow");

4. Triggering a Workflow

const run = await client.workflow.trigger("welcome-flow", ["user@example.com"]);
console.log(run.runId);

// Send a signal later
await client.workflow.sendSignal(run.runId, "user-confirm", { success: true });

API Reference

RocketBaseClient

• auth: General user authentication methods.
• admins: Admin-specific authentication and management.
• collection(name): CRUD and Realtime for a specific collection.
• workflow: Trigger, signal, and monitor durable workflows.
• settings: Manage databases and collection schemas.
• migrations: Run and track schema migrations.
• cron: Manage recurring jobs.

WorkflowContext (Functional ctx or Class this)

• sleep(duration): Suspend execution for a duration (e.g., "1h", "2d", 5000).
• waitForSignal<T>(name): Suspend until an external signal is received.
• parallel(steps[]): Execute multiple steps concurrently with durability.
• runId: The unique ID of the current execution.
• history: Map of completed step results.

Browser

When building with webpack for browsers omit node depenedencies:

{
  webpack: (config, { isServer }) => {
    if (!isServer) {
      config.plugins.push(
        new webpack.NormalModuleReplacementPlugin(/^node:/, (resource) => {
          resource.request = resource.request.replace(/^node:.*/, "noop");
        }),
      );
    }
    return config;
  },
}
