JSForce is an isomorphic JavaScript library that provides a comprehensive interface to Salesforce APIs. It works seamlessly in both Node.js environments and web browsers, enabling developers to build powerful Salesforce integrations with JavaScript.

​

TypeScript Ready

Full TypeScript support with comprehensive type definitions for type-safe development.

Developer Friendly

Intuitive API design with promises, async/await, and an interactive CLI/REPL for exploration.

​

JSForce provides access to all major Salesforce APIs:
  • REST API - CRUD operations, SOQL queries, SOSL searches, and metadata
  • Bulk API (v1 & v2) - Large-scale data operations with millions of records
  • Streaming API - Real-time event notifications using Bayeux/CometD
  • Metadata API - Deploy and retrieve metadata components
  • Tooling API - Developer tools and IDE integration
  • Apex REST - Custom Apex REST endpoints
  • Analytics API - Salesforce Reports and Dashboards

Quick Example

Here’s how simple it is to connect to Salesforce and query data: 
import jsforce from 'jsforce';

const conn = new jsforce.Connection({
  loginUrl: 'https://login.salesforce.com'
});

await conn.login('[email protected]', 'password');

const accounts = await conn.query('SELECT Id, Name FROM Account LIMIT 10');
console.log(`Found ${accounts.totalSize} accounts`);
