name: namespace-sandbox description: Guide for creating and managing Namespace sandboxes using ComputeSDK. Use when building applications that need Namespace cloud container instances with customizable CPU/RAM resources for code execution or isolated development environments.

Namespace Sandboxes with ComputeSDK

Run code on Namespace's cloud container instances through ComputeSDK's unified API. Namespace provides ephemeral containers with customizable CPU and memory allocation — ideal when you need control over compute resources, specific architectures, or lightweight isolated environments.

Setup

npm install computesdk

# .env
COMPUTESDK_API_KEY=your_computesdk_api_key
NSC_TOKEN=your_namespace_nsc_token

Get your ComputeSDK key at https://console.computesdk.com/register

Quick Start

import { compute } from 'computesdk';
// Auto-detects Namespace from environment variables

const sandbox = await compute.sandbox.create();

const result = await sandbox.runCode('print("Hello from Namespace!")');
console.log(result.output);

await sandbox.destroy();

Explicit Configuration

For multi-provider setups or when you want to be explicit:

import { compute } from 'computesdk';

compute.setConfig({
  computesdkApiKey: process.env.COMPUTESDK_API_KEY,
  provider: 'namespace',
  namespace: {
    token: process.env.NSC_TOKEN,
  }
});

const sandbox = await compute.sandbox.create();

Custom Resources

Namespace lets you customize the compute resources for your sandboxes:

compute.setConfig({
  computesdkApiKey: process.env.COMPUTESDK_API_KEY,
  provider: 'namespace',
  namespace: {
    token: process.env.NSC_TOKEN,
    virtualCpu: 4,
    memoryMegabytes: 8192,
  }
});

Namespace Configuration Options

interface NamespaceConfig {
  token?: string;              // Uses NSC_TOKEN env var if not set
  virtualCpu?: number;         // CPU cores (default: 2)
  memoryMegabytes?: number;    // RAM in MB (default: 4096)
  machineArch?: string;        // Architecture (default: 'amd64')
  os?: string;                 // Operating system (default: 'linux')
}

Full API

ComputeSDK provides the same API across all providers: filesystem operations, shell commands, managed servers, overlays, terminals, and client access.
