​
Package Manager Installation

Install near-api-ts using your preferred package manager: 
npm install near-api-ts

​
Requirements

Node.js Version: The library requires Node.js version 24 or higher when running in Node.js environments.
The library also has a peer dependency on Zod for schema validation: 
npm install zod
Zod Version: Requires Zod version 4.3.0 or higher (but less than 5.0.0)

​
Platform Support

The near-api-ts library is designed to work across multiple JavaScript environments:

Node.js

Full support for Node.js 24+ with ESM modules

Browser

Complete browser support with IndexedDB key storage

TypeScript

First-class TypeScript support with full type definitions

Modern Build Tools

Compatible with Vite, Webpack, and other modern bundlers

​
Import Paths

The library provides different entry points for different environments:

​
Universal (Default)

Works in both Node.js and browser environments: 
import { createTestnetClient, createMemorySigner } from 'near-api-ts';

​
Node.js Specific

Includes file-based key service for server environments: 
import { createFileKeyService } from 'near-api-ts/node';

​
Browser Specific

Includes IndexedDB-based key service for browser environments: 
import { createIdbKeyService } from 'near-api-ts/browser';

​
Package Structure

The package exports are configured as follows: 
{
  "exports": {
    ".": {
      "browser": "./dist/browser/index.js",
      "node": "./dist/node/index.js",
      "default": "./dist/universal/index.js"
    },
    "./browser": "./dist/browser/index.js",
    "./node": "./dist/node/index.js"
  }
}
This ensures that your bundler or runtime automatically selects the correct version based on your environment.

​
Verify Installation

After installation, verify that the library is working correctly: 
import { createTestnetClient } from 'near-api-ts';

const client = createTestnetClient();
console.log('NEAR API client created successfully!');
If this runs without errors, you’re ready to start building with NEAR!
