Das offizielle TypeScript/JavaScript SDK für Sim bietet vollständige Typsicherheit und unterstützt sowohl Node.js- als auch Browser-Umgebungen, sodass Sie Workflows programmatisch aus Ihren Node.js-Anwendungen, Webanwendungen und anderen JavaScript-Umgebungen ausführen können.
Das TypeScript SDK bietet vollständige Typsicherheit, Unterstützung für asynchrone Ausführung, automatische Ratenbegrenzung mit exponentiellem Backoff und Nutzungsverfolgung.Installieren Sie das SDK mit Ihrem bevorzugten Paketmanager:
<Tabs items={['npm', 'yarn', 'bun']}>
```bash
npm install simstudio-ts-sdk
```
```bash
yarn add simstudio-ts-sdk
```
```bash
bun add simstudio-ts-sdk
```
Hier ist ein einfaches Beispiel für den Einstieg:
import { SimStudioClient } from 'simstudio-ts-sdk';
// Initialize the client
const client = new SimStudioClient({
apiKey: 'your-api-key-here',
baseUrl: 'https://sim.ai' // optional, defaults to https://sim.ai
});
// Execute a workflow
try {
const result = await client.executeWorkflow('workflow-id');
console.log('Workflow executed successfully:', result);
} catch (error) {
console.error('Workflow execution failed:', error);
}new SimStudioClient(config: SimStudioConfig)Konfiguration:
config.apiKey(string): Ihr Sim API-Schlüsselconfig.baseUrl(string, optional): Basis-URL für die Sim API (standardmäßighttps://sim.ai)
Führt einen Workflow mit optionalen Eingabedaten aus.
const result = await client.executeWorkflow('workflow-id', {
input: { message: 'Hello, world!' },
timeout: 30000 // 30 seconds
});Parameter:
workflowId(string): Die ID des auszuführenden Workflowsoptions(ExecutionOptions, optional):input(any): Eingabedaten, die an den Workflow übergeben werdentimeout(number): Timeout in Millisekunden (Standard: 30000)stream(boolean): Streaming-Antworten aktivieren (Standard: false)selectedOutputs(string[]): Block-Ausgaben, die imblockName.attributeFormat gestreamt werden sollen (z.B.["agent1.content"])async(boolean): Asynchron ausführen (Standard: false)
Rückgabewert: Promise<WorkflowExecutionResult | AsyncExecutionResult>
Wenn async: true, wird sofort mit einer Task-ID zum Abfragen zurückgegeben. Andernfalls wird auf den Abschluss gewartet.
Den Status eines Workflows abrufen (Bereitstellungsstatus usw.).
const status = await client.getWorkflowStatus('workflow-id');
console.log('Is deployed:', status.isDeployed);Parameter:
workflowId(string): Die ID des Workflows
Rückgabewert: Promise<WorkflowStatus>
Überprüfen, ob ein Workflow für die Ausführung bereit ist.
const isReady = await client.validateWorkflow('workflow-id');
if (isReady) {
// Workflow is deployed and ready
}Parameter:
workflowId(string): Die ID des Workflows
Rückgabewert: Promise<boolean>
Den Status einer asynchronen Job-Ausführung abrufen.
const status = await client.getJobStatus('task-id-from-async-execution');
console.log('Status:', status.status); // 'queued', 'processing', 'completed', 'failed'
if (status.status === 'completed') {
console.log('Output:', status.output);
}Parameter:
taskId(string): Die Task-ID, die von der asynchronen Ausführung zurückgegeben wurde
Rückgabewert: Promise<JobStatus>
Antwortfelder:
success(boolean): Ob die Anfrage erfolgreich wartaskId(string): Die Task-IDstatus(string): Einer der Werte'queued','processing','completed','failed','cancelled'metadata(object): EnthältstartedAt,completedAtunddurationoutput(any, optional): Die Workflow-Ausgabe (wenn abgeschlossen)error(any, optional): Fehlerdetails (wenn fehlgeschlagen)estimatedDuration(number, optional): Geschätzte Dauer in Millisekunden (wenn in Bearbeitung/in der Warteschlange)
Einen Workflow mit automatischer Wiederholung bei Rate-Limit-Fehlern unter Verwendung von exponentiellem Backoff ausführen.
const result = await client.executeWithRetry('workflow-id', {
input: { message: 'Hello' },
timeout: 30000
}, {
maxRetries: 3, // Maximum number of retries
initialDelay: 1000, // Initial delay in ms (1 second)
maxDelay: 30000, // Maximum delay in ms (30 seconds)
backoffMultiplier: 2 // Exponential backoff multiplier
});Parameter:
workflowId(string): Die ID des auszuführenden Workflowsoptions(ExecutionOptions, optional): Gleich wieexecuteWorkflow()retryOptions(RetryOptions, optional):maxRetries(number): Maximale Anzahl von Wiederholungen (Standard: 3)initialDelay(number): Anfängliche Verzögerung in ms (Standard: 1000)maxDelay(number): Maximale Verzögerung in ms (Standard: 30000)backoffMultiplier(number): Backoff-Multiplikator (Standard: 2)
Rückgabe: Promise<WorkflowExecutionResult | AsyncExecutionResult>
Die Wiederholungslogik verwendet exponentielles Backoff (1s → 2s → 4s → 8s...) mit ±25% Jitter, um den Thundering-Herd-Effekt zu vermeiden. Wenn die API einen retry-after Header bereitstellt, wird dieser stattdessen verwendet.
Ruft die aktuellen Rate-Limit-Informationen aus der letzten API-Antwort ab.
const rateLimitInfo = client.getRateLimitInfo();
if (rateLimitInfo) {
console.log('Limit:', rateLimitInfo.limit);
console.log('Remaining:', rateLimitInfo.remaining);
console.log('Reset:', new Date(rateLimitInfo.reset * 1000));
}Rückgabe: RateLimitInfo | null
Ruft aktuelle Nutzungslimits und Kontingentinformationen für Ihr Konto ab.
const limits = await client.getUsageLimits();
console.log('Sync requests remaining:', limits.rateLimit.sync.remaining);
console.log('Async requests remaining:', limits.rateLimit.async.remaining);
console.log('Current period cost:', limits.usage.currentPeriodCost);
console.log('Plan:', limits.usage.plan);Rückgabe: Promise<UsageLimits>

runWorkflow();Behandeln Sie verschiedene Fehlertypen, die während der Workflow-Ausführung auftreten können:
import { SimStudioClient, SimStudioError } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
async function executeWithErrorHandling() {

console.error('Invalid JSON in request body');
break;
default:
console.error('Workflow error:', error.message);
}
} else {
console.error('Unexpected error:', error);
}
throw error;
}
}Konfigurieren Sie den Client mit Umgebungsvariablen:
<Tabs items={['Development', 'Production']}>
```typescript
import { SimStudioClient } from 'simstudio-ts-sdk';
// Development configuration
const apiKey = process.env.SIM_API_KEY;
if (!apiKey) {
throw new Error('SIM_API_KEY environment variable is required');
}
const client = new SimStudioClient({
apiKey,
baseUrl: process.env.SIM_BASE_URL // optional
});
```
```typescript
import { SimStudioClient } from 'simstudio-ts-sdk';
// Production configuration with validation
const apiKey = process.env.SIM_API_KEY;
if (!apiKey) {
throw new Error('SIM_API_KEY environment variable is required');
}
const client = new SimStudioClient({
apiKey,
baseUrl: process.env.SIM_BASE_URL || 'https://sim.ai'
});
```
Integration mit einem Express.js-Server:
import express from 'express';
import { SimStudioClient } from 'simstudio-ts-sdk';
const app = express();
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
app.use(express.json());
app.post('/execute-workflow', async (req, res) => {
try {
const { workflowId, input } = req.body;
const result = await client.executeWorkflow(workflowId, {
input,
timeout: 60000
});
res.json({
success: true,
data: result
});
} catch (error) {
console.error('Workflow execution error:', error);
res.status(500).json({
success: false,
error: error instanceof Error ? error.message : 'Unknown error'
});
}
});
app.listen(3000, () => {
console.log('Server running on port 3000');
});Verwendung mit Next.js API-Routen:
// pages/api/workflow.ts or app/api/workflow/route.ts
import { NextApiRequest, NextApiResponse } from 'next';
import { SimStudioClient } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
export default async function handler(
req: NextApiRequest,
res: NextApiResponse
) {
if (req.method !== 'POST') {
return res.status(405).json({ error: 'Method not allowed' });
}
try {
const { workflowId, input } = req.body;
const result = await client.executeWorkflow(workflowId, {
input,
timeout: 30000
});
res.status(200).json(result);
} catch (error) {
console.error('Error executing workflow:', error);
res.status(500).json({
error: 'Failed to execute workflow'
});
}
}Verwendung im Browser (mit korrekter CORS-Konfiguration):
import { SimStudioClient } from 'simstudio-ts-sdk';
// Note: In production, use a proxy server to avoid exposing API keys
const client = new SimStudioClient({
apiKey: 'your-public-api-key', // Use with caution in browser
baseUrl: 'https://sim.ai'
});
async function executeClientSideWorkflow() {
try {
const result = await client.executeWorkflow('workflow-id', {
input: {
userInput: 'Hello from browser'
}
});
console.log('Workflow result:', result);
// Update UI with result
document.getElementById('result')!.textContent =
JSON.stringify(result.output, null, 2);
} catch (error) {
console.error('Error:', error);
}
}Datei-Objekte werden automatisch erkannt und in das Base64-Format konvertiert. Fügen Sie sie in Ihrem Input unter dem Feldnamen ein, der dem API-Trigger-Inputformat Ihres Workflows entspricht.
Das SDK konvertiert Datei-Objekte in dieses Format:
{
type: 'file',
data: 'data:mime/type;base64,base64data',
name: 'filename',
mime: 'mime/type'
}Alternativ können Sie Dateien manuell im URL-Format bereitstellen:
{
type: 'url',
data: 'https://example.com/file.pdf',
name: 'file.pdf',
mime: 'application/pdf'
}<Tabs items={['Browser', 'Node.js']}>
```typescript
import { SimStudioClient } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.NEXT_PUBLIC_SIM_API_KEY!
});
// From file input
async function handleFileUpload(event: Event) {
const input = event.target as HTMLInputElement;
const files = Array.from(input.files || []);
// Include files under the field name from your API trigger's input format
const result = await client.executeWorkflow('workflow-id', {
input: {
documents: files, // Must match your workflow's "files" field name
instructions: 'Analyze these documents'
}
});
console.log('Result:', result);
}
```
```typescript
import { SimStudioClient } from 'simstudio-ts-sdk';
import fs from 'fs';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
// Read file and create File object
const fileBuffer = fs.readFileSync('./document.pdf');
const file = new File([fileBuffer], 'document.pdf', {
type: 'application/pdf'
});
// Include files under the field name from your API trigger's input format
const result = await client.executeWorkflow('workflow-id', {
input: {
documents: [file], // Must match your workflow's "files" field name
query: 'Summarize this document'
}
});
```
Erstellen Sie einen benutzerdefinierten React-Hook für die Workflow-Ausführung:
import { useState, useCallback } from 'react';
import { SimStudioClient, WorkflowExecutionResult } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
interface UseWorkflowResult {
result: WorkflowExecutionResult | null;
loading: boolean;
error: Error | null;
executeWorkflow: (workflowId: string, input?: any) => Promise<void>;
}
export function useWorkflow(): UseWorkflowResult {
const [result, setResult] = useState<WorkflowExecutionResult | null>(null);
const [loading, setLoading] = useState(false);
const [error, setError] = useState<Error | null>(null);
const executeWorkflow = useCallback(async (workflowId: string, input?: any) => {
setLoading(true);
setError(null);
setResult(null);
try {
const workflowResult = await client.executeWorkflow(workflowId, {
input,
timeout: 30000
});
setResult(workflowResult);
} catch (err) {
setError(err instanceof Error ? err : new Error('Unknown error'));
} finally {
setLoading(false);
}
}, []);
return {
result,
loading,
error,
executeWorkflow
};
}
// Usage in component
function WorkflowComponent() {
const { result, loading, error, executeWorkflow } = useWorkflow();
const handleExecute = () => {
executeWorkflow('my-workflow-id', {
message: 'Hello from React!'
});
};
return (
<div>
<button onClick={handleExecute} disabled={loading}>
{loading ? 'Executing...' : 'Execute Workflow'}
</button>
{error && <div>Error: {error.message}</div>}
{result && (
<div>
<h3>Result:</h3>
<pre>{JSON.stringify(result, null, 2)}</pre>
</div>
)}
</div>
);
}Führen Sie Workflows asynchron für lang laufende Aufgaben aus:
import { SimStudioClient, AsyncExecutionResult } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
async function executeAsync() {
try {
// Start async execution
const result = await client.executeWorkflow('workflow-id', {
input: { data: 'large dataset' },
async: true // Execute asynchronously
});
// Check if result is an async execution
if ('taskId' in result) {
console.log('Task ID:', result.taskId);
console.log('Status endpoint:', result.links.status);
// Poll for completion
let status = await client.getJobStatus(result.taskId);
while (status.status === 'queued' || status.status === 'processing') {
console.log('Current status:', status.status);
await new Promise(resolve => setTimeout(resolve, 2000)); // Wait 2 seconds
status = await client.getJobStatus(result.taskId);
}
if (status.status === 'completed') {
console.log('Workflow completed!');
console.log('Output:', status.output);
console.log('Duration:', status.metadata.duration);
} else {
console.error('Workflow failed:', status.error);
}
}
} catch (error) {
console.error('Error:', error);
}
}
executeAsync();Automatische Behandlung von Rate-Limits mit exponentiellem Backoff:
import { SimStudioClient, SimStudioError } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
async function executeWithRetryHandling() {
try {
// Automatically retries on rate limit
const result = await client.executeWithRetry('workflow-id', {
input: { message: 'Process this' }
}, {
maxRetries: 5,
initialDelay: 1000,
maxDelay: 60000,
backoffMultiplier: 2
});
console.log('Success:', result);
} catch (error) {
if (error instanceof SimStudioError && error.code === 'RATE_LIMIT_EXCEEDED') {
console.error('Rate limit exceeded after all retries');
// Check rate limit info
const rateLimitInfo = client.getRateLimitInfo();
if (rateLimitInfo) {
console.log('Rate limit resets at:', new Date(rateLimitInfo.reset * 1000));
}
}
}
}Überwachen Sie Ihre Kontonutzung und -limits:
import { SimStudioClient } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
async function checkUsage() {
try {
const limits = await client.getUsageLimits();
console.log('=== Rate Limits ===');
console.log('Sync requests:');
console.log(' Limit:', limits.rateLimit.sync.limit);
console.log(' Remaining:', limits.rateLimit.sync.remaining);
console.log(' Resets at:', limits.rateLimit.sync.resetAt);
console.log(' Is limited:', limits.rateLimit.sync.isLimited);
console.log('\nAsync requests:');
console.log(' Limit:', limits.rateLimit.async.limit);
console.log(' Remaining:', limits.rateLimit.async.remaining);
console.log(' Resets at:', limits.rateLimit.async.resetAt);
console.log(' Is limited:', limits.rateLimit.async.isLimited);
console.log('\n=== Usage ===');
console.log('Current period cost: $' + limits.usage.currentPeriodCost.toFixed(2));
console.log('Limit: $' + limits.usage.limit.toFixed(2));
console.log('Plan:', limits.usage.plan);
const percentUsed = (limits.usage.currentPeriodCost / limits.usage.limit) * 100;
console.log('Usage: ' + percentUsed.toFixed(1) + '%');
if (percentUsed > 80) {
console.warn('⚠️ Warning: You are approaching your usage limit!');
}
} catch (error) {
console.error('Error checking usage:', error);
}
}
checkUsage();Führen Sie Workflows mit Echtzeit-Streaming-Antworten aus:
import { SimStudioClient } from 'simstudio-ts-sdk';
const client = new SimStudioClient({
apiKey: process.env.SIM_API_KEY!
});
async function executeWithStreaming() {
try {
// Enable streaming for specific block outputs
const result = await client.executeWorkflow('workflow-id', {
input: { message: 'Count to five' },
stream: true,
selectedOutputs: ['agent1.content'] // Use blockName.attribute format
});
console.log('Workflow result:', result);
} catch (error) {
console.error('Error:', error);
}
}Die Streaming-Antwort folgt dem Server-Sent Events (SSE) Format:
data: {"blockId":"7b7735b9-19e5-4bd6-818b-46aae2596e9f","chunk":"One"}
data: {"blockId":"7b7735b9-19e5-4bd6-818b-46aae2596e9f","chunk":", two"}
data: {"event":"done","success":true,"output":{},"metadata":{"duration":610}}
data: [DONE]
React Streaming Beispiel:
import { useState, useEffect } from 'react';
function StreamingWorkflow() {
const [output, setOutput] = useState('');
const [loading, setLoading] = useState(false);
const executeStreaming = async () => {
setLoading(true);
setOutput('');
// IMPORTANT: Make this API call from your backend server, not the browser
// Never expose your API key in client-side code
const response = await fetch('https://sim.ai/api/workflows/WORKFLOW_ID/execute', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': process.env.SIM_API_KEY! // Server-side environment variable only
},
body: JSON.stringify({
message: 'Generate a story',
stream: true,
selectedOutputs: ['agent1.content']
})
});
const reader = response.body?.getReader();
const decoder = new TextDecoder();
while (reader) {
const { done, value } = await reader.read();
if (done) break;
const chunk = decoder.decode(value);
const lines = chunk.split('\n\n');
for (const line of lines) {
if (line.startsWith('data: ')) {
const data = line.slice(6);
if (data === '[DONE]') {
setLoading(false);
break;
}
try {
const parsed = JSON.parse(data);
if (parsed.chunk) {
setOutput(prev => prev + parsed.chunk);
} else if (parsed.event === 'done') {
console.log('Execution complete:', parsed.metadata);
}
} catch (e) {
// Skip invalid JSON
}
}
}
}
};
return (
<div>
<button onClick={executeStreaming} disabled={loading}>
{loading ? 'Generating...' : 'Start Streaming'}
</button>
<div style={{ whiteSpace: 'pre-wrap' }}>{output}</div>
</div>
);
