Puter SDK

---

The Unofficial JavaScript SDK for interacting with the Puter Cloud Platform. If you don't have an account you can Signup from here for free (You'll get a free 1Gb from this link). This SDK provides a simple and consistent interface for working with Puter's APIs, including file management, app deployment, AI services, and more.

Features

- File Management
- List, upload, download, and manage files
- Create and manage directories
- File operations (copy, move, rename, delete)

- App Management
- Create, update, and delete apps
- Manage app configurations (WIP)
- Deploy static sites

- Key-Value Store
- Basic Operations: Set, get, and delete key/value pairs
- Handle various data types (strings, numbers, objects, arrays)
- Increment/Decrement: Atomic increment/decrement operations with support for custom amounts
- upport for custom amounts: Flush all keys, list keys with glob pattern support

- Sites Management
- Create, update, and delete sites
- Deploy static sites from existing directory

- AI Services
- Chat completions (streaming and non-streaming)
- Image generation
- Optical Character Recognition (OCR)
- Text-to-Speech (TTS)

- User Management
- Authentication (login/logout)
- User information
- Session management

- Subdomain Management

Usage

$3

`javascript
import PuterClient from 'puter-sdk';

// Initialize the client
const puter = new PuterClient({
token: 'your-api-token', // Optional, can be set later
baseURL: 'https://api.puter.com' // Optional
});
`

$3

`javascript
// Login using your credentials:
const puter = await puter.auth.signIn('username', 'password');
console.log('Logged in with token:', puter.token);

// or just create a new instance:
const puter = new PuterClient();
// P.S. The client will look for PUTER_API_KEY in .env file name or provide as a variable environnement.

// Get current user
const userInfo = await puter.auth.getUser();
console.log('User info:', userInfo);

// Logout
await puter.auth.signOut();
`

$3

`javascript
// List directory contents
const files = await puter.fs.readdir('/');
console.log('Files:', files);

// Upload a file
const file = new Blob(['Hello, Puter!'], { type: 'text/plain' });
const uploadResult = await puter.fs.upload({
file,
path: '/uploads',
name: 'hello.txt'
});
console.log('Upload result:', uploadResult);

// Create a directory
const dirResult = await puter.fs.mkdir({
path: '/new-directory'
});
console.log('Directory created:', dirResult);
`

$3

`javascript
// List all apps
const apps = await puter.apps.list();
console.log('Apps:', apps);
`

$3

`javascript
// Create a key/value pair
const result = await puter.kv.set('testKey', 'testValue');
const value = await puter.kv.get('testKey');

console.log(value set: ${value});

// Deleting by key
const result = await puter.kv.del('testKey');
console.log(result of delete operation: ${result});
`

$3

`javascript
// Basic chat completion
const chatResponse = await puter.ai.chat([{
role: 'user',
content: 'What is Puter?'
}]);
console.log('AI response:', chatResponse.message.content);

// Chat completion with a simple string prompt
const simpleResponse = await puter.ai.chat('Tell me about cloud computing');
console.log('Simple response:', simpleResponse.message.content);

// Chat completion in test mode
const testResponse = await puter.ai.chat('Generate a test response', true);
console.log('Test mode response:', testResponse.message.content);

// Chat completion with parameters
const customResponse = await puter.ai.chat(
[{
role: 'user',
content: 'Write a short poem about technology'
}],
{
model: 'gpt-4o-mini', // Specify model
temperature: 0.7, // Control randomness
max_tokens: 150 // Limit response length
}
);
console.log('Custom AI response:', customResponse.message.content);

// List available AI models
const models = await puter.ai.listModels();
console.log('Available models by provider:', models);
// Example output: { 'openai-completion': ['gpt-4o', 'gpt-4o-mini', ...], ... }

// List models for a specific provider
const openaiModels = await puter.ai.listModels('openai-completion');
console.log('OpenAI models:', openaiModels);

// List all available AI model providers
const providers = await puter.ai.listModelProviders();
console.log('Available providers:', providers);
// Example output: ['openai-completion', 'anthropic', 'openrouter', ...]

// Streaming chat completion
const stream = await puter.ai.chat(
[{
role: 'user',
content: 'Explain quantum computing'
}],
{
stream: true,
temperature: 0.5,
max_tokens: 500
}
);

// Process the stream
let buffer = '';
const processLine = (line) => {
const trimmed = line.trim();
if (!trimmed) return;
const payload = trimmed.startsWith('data:') ? trimmed.slice(5).trim() : trimmed;
try {
const data = JSON.parse(payload);
if (data.success && data.result?.message?.content) {
process.stdout.write(data.result.message.content);
return;
}
if (data.type === 'text' && data.text) {
process.stdout.write(data.text);
}
} catch (_) {
// Ignore parse errors for partial chunks
}
};
stream.on('data', (chunk) => {
buffer += chunk.toString();
const lines = buffer.split(/\r?\n/);
buffer = lines.pop();
for (const line of lines) processLine(line);
});
stream.on('end', () => {
if (buffer) processLine(buffer);
process.stdout.write('\n');
});

// Image generation
const image = await puter.ai.txt2img({
prompt: 'A futuristic cityscape'
});
console.log('Generated image:', image.url);

// OCR
const ocrResult = await puter.ai.img2txt('file-id-123');
console.log('Extracted text:', ocrResult.text);

// Text-to-Speech
const audioStream = await puter.ai.txt2speech({
text: 'Hello, world!',
voice: 'voice-1'
});
// Handle the audio stream...
`

$3

`javascript
// List web sites
const sites = await puter.hosting.list();
console.log('sites:', sites);
`

Error Handling

The SDK uses custom error classes for consistent error handling:

`javascript
try {
await puter.fs.delete('/protected-file.txt');
} catch (error) {
if (error.code === 'PERMISSION_DENIED') {
console.error('Permission denied:', error.message);
} else {
console.error('An error occurred:', error.message);
}
}
``
