kurdcoin-sdk v7.0.1
js-kurdcoin-sdk is a Javascript library for communicating with a Stellar Horizon server. It is used for building Stellar apps either on Node.js or in the browser.
It provides:
- a networking layer API for Horizon endpoints.
- facilities for building and signing transactions, for communicating with a Stellar Horizon instance, and for submitting transactions or querying network history.
kurdcoin-sdk vs kurdcoin-base
kurdcoin-sdk is a high-level library that serves as client-side API for Horizon. kurdcoin-base is lower-level library for creating Stellar primitive constructs via XDR helpers and wrappers.
Most people will want kurdcoin-sdk instead of kurdcoin-base. You should only use kurdcoin-base if you know what you're doing!
If you add kurdcoin-sdk
to a project, do not add kurdcoin-base
! Mis-matching
versions could cause weird, hard-to-find bugs. kurdcoin-sdk
automatically
installs kurdcoin-base
and exposes all of its exports in case you need them.
Important! The Node.js version of the
kurdcoin-base
(kurdcoin-sdk
dependency) package uses thesodium-native
package as an optional dependency.sodium-native
is a low level binding to libsodium, (an implementation of Ed25519 signatures). If installation ofsodium-native
fails, or it is unavailable,kurdcoin-base
(andkurdcoin-sdk
) will fallback to using thetweetnacl
package implementation.If you are using
kurdcoin-sdk
/kurdcoin-base
in a browser you can ignore this. However, for production backend deployments you should be usingsodium-native
. Ifsodium-native
is successfully installed and working theKurdCoinSdk.FastSigning
variable will returntrue
.
Quick start
Using npm to include js-kurdcoin-sdk in your own project:
npm install --save kurdcoin-sdk
Alternatively, you can use cdnjs in a browser:
<script src="https://cdnjs.cloudflare.com/ajax/libs/kurdcoin-sdk/{version}/kurdcoin-sdk.js"></script>
Install
To use as a module in a Node.js project
- Install it using npm:
npm install --save kurdcoin-sdk
- require/import it in your JavaScript:
var KurdCoinSdk = require('kurdcoin-sdk');
To self host for use in the browser
- Install it using bower:
bower install kurdcoin-sdk
- Include it in the browser:
<script src="./bower_components/kurdcoin-sdk/kurdcoin-sdk.js"></script>
<script>
console.log(KurdCoinSdk);
</script>
If you don't want to use install Bower, you can copy built JS files from the bower-js-kurdcoin-sdk repo.
To use the cdnjs hosted script in the browser
- Instruct the browser to fetch the library from cdnjs, a 3rd party service that hosts js libraries:
<script src="https://cdnjs.cloudflare.com/ajax/libs/kurdcoin-sdk/{version}/kurdcoin-sdk.js"></script>
<script>
console.log(KurdCoinSdk);
</script>
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-kurdcoin-sdk itself
- Clone the repo:
git clone https://github.com/stellar/js-kurdcoin-sdk.git
- Install dependencies inside js-kurdcoin-sdk folder:
cd js-kurdcoin-sdk
npm install
- Install Node 10.16.3
Because we support earlier versions of Node, please install and develop on Node 10.16.3 so you don't get surprised when your code works locally but breaks in CI.
Here's out to install nvm
if you haven't: https://github.com/creationix/nvm
nvm install
# if you've never installed 10.16.3 before you'll want to re-install yarn
npm install -g yarn
If you work on several projects that use different Node versions, you might it helpful to install this automatic version manager: https://github.com/wbyoung/avn
- Observe the project's code style
While you're making changes, make sure to run the linter-watcher to catch any linting errors (in addition to making sure your text editor supports ESLint)
node_modules/.bin/gulp watch
If you're working on a file not in src
, limit your code to Node 6.16 ES! See
what's supported here: https://node.green/ (The reason is that our npm library
must support earlier versions of Node, so the tests need to run on those
versions.)
How to use with React-Native
- Add the following postinstall script:
yarn rn-nodeify --install url,events,https,http,util,stream,crypto,vm,buffer --hack --yarn
yarn add -D rn-nodeify
- Uncomment
require('crypto')
on shim.js react-native link react-native-randombytes
- Create file
rn-cli.config.js
module.exports = {
resolver: {
extraNodeModules: require("node-libs-react-native"),
},
};
- Add
import "./shim";
to the top ofindex.js
yarn add kurdcoin-sdk
There is also a sample that you can follow.
