📚 Satori Node.js SDK

Welcome to the official documentation for Satori Node.js SDK! 🚀
This library allows you to interact easily and efficiently with the Satori database via WebSockets, supporting CRUD operations, real-time notifications, and advanced queries.

✨ Main Features

• Ultra-fast CRUD operations ⚡
• Advanced queries using field_array 🔍
• Real-time notifications 📢
• Graph-like relations (vertices and references) 🕸️
• Data encryption and decryption 🔐

🚀 Installation

npm install satori-node

🏁 Basic Usage

import { Satori } from 'satori-node';

const client = new Satori({
  username: 'user',
  password: 'password',
  host: 'ws://localhost:2310'
});

await client.connect();

If you are inserting a vector you must specify data to a [f32] and type to vector

🗃️ CRUD Operations

Create Data

await client.set({
  key: 'user:123',
  data: { name: 'John', email: '[email protected]' },
  type: 'user' 
});

If you are inserting a vector you must specify data to a [f32] and type to vector

Read Data

const user = await client.get({ key: 'user:123' });

Modify a Field

await client.put({
  key: 'user:123',
  replace_field: 'name',
  replace_value: 'Peter'
});

Delete Data

await client.delete({ key: 'user:123' });

🧩 Advanced Queries with field_array 🔍

You can perform operations on multiple objects that meet certain conditions using the field_array field:

await client.get({
  field_array: [
    { field: 'email', value: '[email protected]' }
  ],
});

• field_array is an array of conditions { field, value }.
• You can combine it with one: true to get only the first matching result.

🔔 Real-time Notifications

Receive automatic updates when an object changes!

client.notify('user:123', data => {
  console.log('User updated!', data);
});

🕸️ Relations and Graphs

You can create relationships between objects (vertices):

await client.setVertex({
  key: 'user:123',
  vertex: 'friend:456',
  relation: 'friend',
  encryption_key: 'secret'
});

And traverse the graph with DFS:

await client.dfs({ node: 'user:123', encryption_key: 'secret' });

🔐 Encryption and Security

Easily encrypt and decrypt data:

await client.encrypt({ key: 'user:123', encryption_key: 'secret' });
await client.decrypt({ key: 'user:123', encryption_key: 'secret' });

🧰 Schema Class (Data Model)

You can use the Schema class to model your data in an object-oriented way:

import Schema from 'satori-node/schema';

class User extends Schema {
  // Define your fields here
}

const user = new User({ name: 'Anna' }, client, 'user');
await user.set();

It includes useful methods such as:

• set, delete, encrypt, setVertex, getVertex, deleteVertex, dfs
• Array methods: push, pop, splice, remove

📦 Array Manipulation Methods

Below are the available methods to manipulate arrays in the Satori database using the Node.js client:

🔹 push

Adds a value to an existing array in an object.

await client.push({ key: 'user:123', array: 'friends', value: 'user:456' });

• key: Object key.
• array: Name of the array.
• value: Value to add.

🔹 pop

Removes the last element from an array in an object.

await client.pop({ key: 'user:123', array: 'friends' });

• key: Object key.
• array: Name of the array.

🔹 splice

Modifies an array in an object (for example, to cut or replace elements).

await client.splice({ key: 'user:123', array: 'friends' });

• key: Object key.
• array: Name of the array.

🔹 remove

Removes a specific value from an array in an object.

await client.remove({ key: 'user:123', array: 'friends', value: 'user:456' });

• key: Object key.
• array: Name of the array.
• value: Value to remove.

🤖 AI Methods

Satori has AI features integrated that boost developers productivity.

🔹 set_middleware

Make the LLM analyze incoming querys and decide if it must reject them, accept them or modify them.

await client.set_middleware({
    "operation": "SET",
    "middleware": "Only accept requests that have the amount field specified, and convert its value to dollars"
});

🔹 ann

Perform an Aproximate Nearest Neighbors search

await client.ann({'key' : 'user:123', 'top_k' : '5'});

• key: Source object key.
• vector: Vector of f32 instead of key
• top_k: Number of nearest neighbors to return

🔹 query

Make querys in natural language

await client.query({'query' : 'Insert the value 5 into the grades array of user:123', 'backend' : 'openai:gpt-4o-mini'|);

• query: Your query in natural language.
• ref: The LLM backend. Must be openai:model-name or ollama:model-name, if not specified openai:gpt-4o-mini will be used as default. If you're using OpenAI as your backend you must specify the OPENAI_API_KEY env variable.

🔹 ask

Ask question about your data in natural language

await client.ask({'question' : 'How many user over 25 years old do we have. Just return the number.', 'backend' : 'openai:gpt-4o-mini'});

• question: Your question in natural language.
• ref: The LLM backend. Must be openai:model-name or ollama:model-name, if not specified openai:gpt-4o-mini will be used as default. If you're using OpenAI as your backend you must specify the OPENAI_API_KEY env variable.

Analytics

🔹 get_operations

Returns all operations executed on the database.

🔹 get_access_frequency

Returns the number of times an object has been queried or accessed.

await client.get_access_frequency({'key' : 'jhon'})

Responses

All responses obbey the following pattern:

{
  data: any //the requested data if any
  message: string //status message
  type: string //SUCCESS || ERROR
}

AI responses obbey a different patern:

ask

{
  response: string //response to the question
}

query

{
  result: string //response from the operation made in the db
  status: string //status
}

ann

{
  results: array //response from the operation made in the db
}

🧠 Key Concepts

• key: Unique identifier of the object.
• type: Object type (e.g., 'user').
• field_array: Advanced filters for bulk operations.
• notifications: Subscription to real-time changes.
• vertices: Graph-like relationships between objects.
