# HSN JavaScript Library
*Transplant from [Cosmostation](https://github.com/cosmostation/cosmosjs) and Developing by [HSN](https://www.hsn.link/)*
## Installation
### NPM
```shell
npm install hsnjs
```
### Import
```javascript
const HSN = require('hsnjs');
```
### Usage
#### local
1. Generate mnemonic
```javascript
const HSN = require('hsnjs');
...
const hsn = HSN.network("https://hsn.link","hsn");
let mnemonic = hsn.genMnemonic();
console.log(mnemonic)
//entry age emotion elbow output paper nut pumpkin eagle fancy indicate inspire
```
2. Get address from mnemonic
```javascript
const HSN = require('hsnjs');
...
const hsn = HSN.network("https://hsn.link","hsn");
let address = hsn.getAddress(mnemonic);
console.log(address);
//hsn1jqs9tu58ws7n0h9sxg0qjaurcskmyrjcqn72je
```
3. Get Prikey from mnemonic
```javascript
const HSN = require('hsnjs');
...
const hsn = HSN.network("https://hsn.link","hsn");
let priKey = hsn.getECPairPriv(mnemonic)
//other code
```
Get account infomation from HSN LCD
```javascript
const HSN = require('hsnjs');
...
const hsn = HSN.network("https://hsn.link","hsn");
hsn.getAccounts(address).then(data =>{
console.log("the account_number is ",data.value.account_number);
console.log("the sequence is ",data.value.sequence);
//more data.value
})
```
