Band Protocol JS Library

Official Javascript Client for Band Chain

Code Style: prettierTypeScriptMIT LicenceDependency StatusdevDependency Status

The library allows Web, Node.js and React Native environment to connect with Band Chain. The code itself is written in TypeScript, but deployed as older ES5 ia Browserify to support older browser and React Native environments.

Dependencies

Installation

NPM

npm i --save bandprotocol

Basic Usage

importBandProtocolClientfrom'bandprotocol'import{secretKey}from'./config'constclient=newBandProtocolClient({httpEndpoint: 'http://localhost:26657',keyProvider: secretKey,})

Key Generation

This library supports secure key generations using ED25519 algorithm.

const{
mnemonic,// Array<string x 12> of Mnemonic phrase
secretKey,// 64-byte hex string secret key
verifyKey,// 32-byte hex string public key
address,// IBAN-style address}=BandProtocolClient.generateRandomKey()

Transaction Generation

Every transaction is created on the remote node via JSON-RPC protocol and signed on the client. This design allows higher portability comparing to client-generated transactions, while the client keeps its secret keys secured.

See BandProtocol's Gitbook for documentation on transaction formats.

importBandProtocolClientfrom'bandprotocol'// Initialize clientconstclient=newBandProtocolClient({httpEndpoint: 'http://localhost:26657',keyProvider: '<secretKey>',})// Generate unsigned transaction from nodeconstunsignedTx=awaitclient.blockchain.txgen({msgid: 1,vk: '6ddb22994b551f4da5818e7a257d467e9af753348194f31dddc5f9aa489d3da1',dest: 'AX62 ECTZ WZZ5 XVTG N8NL 6EVB 9TPH TELJ ZBRL',token: 'BX63 AAAA AAAA AAAA AAAA AAAA AAAA AAAA AAAA',value: '200000',})// Sign the transactionconstsignedTx=client.key.sign(unsignedTx)// Broadcast the signed transactionconstresult=awaitclient.blockchain.broadcastTxn(signedTx)

Encrypted Secret Key (SecretBox)

The client supports secret key encryption via Libsodium's Secret-key encryption. Application server can store the secretbox without exposing the risk of leaking user's secret keys, given that the passcodes are strong enough.

To create secretbox from secret key, you'll need to initialize the client with secret key:

constpasscode='<some_user_defined_passcode>'constclient=newBandProtocolClient({keyProvider: '<secretKey>'})constsecretbox=client.encrypt(passcode)

To restore client instance and secret key:

constclient=newBandProtocolClient({keyProvider: {secretbox: '<encrypted_secretbox>',passcode: '<user_passcode>',},})constsecretKey=client.getSecretKey()

Development

Make sure you have Node.js v8+ installed. Then run:

yarn install

Test

Only Unit Tests are implemented for now. Integration tests with testnet can be possible, and we highly encourage you to contribute to make this happen.

yarn test

Build

To make it compatible with React Native, the TypeScript code is compiled and shimmed to avoid direct call of Node.js libraries. compile.js takes care of compilation process using Browserify.

yarn build

Band Protocol JS Library

Official Javascript Client for Band Chain
Code Style: prettierTypeScriptMIT LicenceDependency StatusdevDependency Status
The library allows Web, Node.js and React Native environment to connect with Band Chain. The code itself is written in TypeScript, but deployed as older ES5 ia Browserify to support older browser and React Native environments.
Dependencies
Installation
NPM
npm i --save bandprotocol

Basic Usage
importBandProtocolClientfrom'bandprotocol'import{secretKey}from'./config'constclient=newBandProtocolClient({httpEndpoint: 'http://localhost:26657',keyProvider: secretKey,})
Key Generation
This library supports secure key generations using ED25519 algorithm.
const{
mnemonic,// Array<string x 12> of Mnemonic phrase
secretKey,// 64-byte hex string secret key
verifyKey,// 32-byte hex string public key
address,// IBAN-style address}=BandProtocolClient.generateRandomKey()
Transaction Generation
Every transaction is created on the remote node via JSON-RPC protocol and signed on the client. This design allows higher portability comparing to client-generated transactions, while the client keeps its secret keys secured.
See BandProtocol's Gitbook for documentation on transaction formats.
importBandProtocolClientfrom'bandprotocol'// Initialize clientconstclient=newBandProtocolClient({httpEndpoint: 'http://localhost:26657',keyProvider: '<secretKey>',})// Generate unsigned transaction from nodeconstunsignedTx=awaitclient.blockchain.txgen({msgid: 1,vk: '6ddb22994b551f4da5818e7a257d467e9af753348194f31dddc5f9aa489d3da1',dest: 'AX62 ECTZ WZZ5 XVTG N8NL 6EVB 9TPH TELJ ZBRL',token: 'BX63 AAAA AAAA AAAA AAAA AAAA AAAA AAAA AAAA',value: '200000',})// Sign the transactionconstsignedTx=client.key.sign(unsignedTx)// Broadcast the signed transactionconstresult=awaitclient.blockchain.broadcastTxn(signedTx)
Encrypted Secret Key (SecretBox)
The client supports secret key encryption via Libsodium's Secret-key encryption. Application server can store the secretbox without exposing the risk of leaking user's secret keys, given that the passcodes are strong enough.
To create secretbox from secret key, you'll need to initialize the client with secret key:
constpasscode='<some_user_defined_passcode>'constclient=newBandProtocolClient({keyProvider: '<secretKey>'})constsecretbox=client.encrypt(passcode)
To restore client instance and secret key:
constclient=newBandProtocolClient({keyProvider: {secretbox: '<encrypted_secretbox>',passcode: '<user_passcode>',},})constsecretKey=client.getSecretKey()
Development
Make sure you have Node.js v8+ installed. Then run:
yarn install

Test
Only Unit Tests are implemented for now. Integration tests with testnet can be possible, and we highly encourage you to contribute to make this happen.
yarn test

Build
To make it compatible with React Native, the TypeScript code is compiled and shimmed to avoid direct call of Node.js libraries. compile.js takes care of compilation process using Browserify.
yarn build
