Practical overview

When it fits

Use it when a browser or Node.js application needs a JavaScript or TypeScript connection to Stellar Horizon or Soroban RPC, or needs Stellar transaction construction and signing facilities.

Who it is for

  • JavaScript and TypeScript developers building Stellar applications.
  • Teams creating browser interfaces or Node.js services for Stellar.
  • Developers building Soroban clients through JSON-RPC.

Documented uses

  • Query Stellar Horizon data and network history.
  • Communicate with Horizon REST endpoints and Soroban JSON-RPC.
  • Construct and sign Stellar transactions.
  • Submit transactions through a Stellar Horizon instance.
  • Generate TypeScript bindings for Stellar smart contracts through the CLI.
Before you choose

Requirements & limits

The public repository identifies the project as open source under the Apache-2.0 license. The package is available through npm, pnpm, yarn, Deno's npm support and a documented browser CDN path.

  • Choose the full package when the application needs Horizon, Soroban RPC or related networking features.
  • Use the /base subpath when only offline primitives such as StrKey, Keypair, TransactionBuilder or XDR are needed.
  • Consider the native-fetch default or documented Axios build according to the application's HTTP transport needs.
  • Review version and protocol compatibility before using an older SDK release; the repository identifies version 16 and version 17 as the relevant choices described in its documentation.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add Stellar JS SDK to a JavaScript project

Install the SDK and import its JavaScript or TypeScript modules.

Before you start

  • A JavaScript or TypeScript project using npm, pnpm, yarn or Deno's npm support.

Steps

  1. Install @stellar/stellar-sdk with npm, pnpm, yarn or Deno's npm support.

  2. Import the SDK with CommonJS or ES module syntax.

  3. For browser use, add the documented CDN bundle instead of a package-manager installation.

Expected outcome

The project has access to Stellar SDK modules for Horizon, Soroban RPC and Stellar transaction operations.

Guide limitations

  • The guide covers installation and importing; it does not document a complete application workflow or transaction submission sequence.
  • The CDN requires a specific SDK version number from the releases page.
