wavelet-client


A developer-friendly stateless HTTP client for interacting with a Wavelet node. Wrriten in JavaScript.

$3

Starting from v2, wavelet-client will support the new version of Wavelet (Himitsu).

For support of older Wavelet please use v1.

The entire source code of this client was written to just fit within a single JavaScript file to make
the underlying code simple and easy to understand. The client has a _very_ minimal set of dependencies
that are well-audited.

The client has been tested to work on both NodeJS alongside on the browser. As a warning, the client uses
some newer language features such as big integers which may require a polyfill.

Setup

``shell
yarn add wavelet-client
`

Usage

`javascript
const {Wavelet, Contract, TAG_TRANSFER, JSBI} = require('wavelet-client');

const BigInt = JSBI.BigInt;
