js-stellar-sdk vs js-stellar-base-react-native
js-stellar-sdk is a high-level library that serves as client side API for Horizon. This library makes extensive use of the lower-level js-stellar-base-react-native and exposes js-stellar-base-react-native classes via its export object. js-stellar-base-react-native can be used as a standalone library for creating Stellar primitive constructs via XDR helpers and wrappers. js-stellar-base-react-native doesn't depend on connecting to Horizon.
js-stellar-sdk exposes all js-stellar-base-react-native classes so you don't have to install js-stellar-base-react-native along js-stellar-sdk.
Using npm to include js-stellar-sdk in your own project:
npm install --save stellar-sdk
For browsers, use Bower to install js-stellar-sdk. It exports a
StellarSdk. The example below assumes you have

To use as a module in a Node.js project
- Install it using npm:
npm install --save stellar-sdk
var StellarSdk = ;
Help! I'm having trouble installing the SDK on Windows
Unfortunately, the Stellar platform development team mostly works on OS X and Linux, and so sometimes bugs creep through that are specific to windows. When installing stellar-sdk on windows, you might see an error that looks similar to the following:
error MSB8020: The build tools
To resolve this issue, you should upgrade your version of nodejs, node-gyp and then re-attempt to install the offending package using
npm install -g --msvs_version=2015 ed25519. Afterwards, retry installing stellar-sdk as normal.
If you encounter the error: "failed to find C:\OpenSSL-Win64", You need to install OpenSSL. More information about this issue can be found here.

To self host for use in the browser
- Install it using bower:
bower install stellar-sdk
- Include it in the browser:
If you don't want to use install Bower, you can copy built JS files from the bower-js-stellar-sdk repo.

- Instruct the browser to fetch the library from cdnjs, a 3rd party service that hosts js libraries:
Note that this method relies using a third party to host the JS library. This may not be entirely secure.
Make sure that you are using the latest version number. They can be found on the releases page in Github.
To develop and test js-stellar-sdk itself
- Clone the repo:
git clone https://github.com/stellar/js-stellar-sdk.git
