REPL

About

This repository contains javascript console for waves blockchain. It is built on top of jsconsole and have predefined functions to work with waves

Builtin functions

JS lib

Console uses waves-transactions library. Top level library functions are bound to console global scope. The difference is that in console, seed argument is equal to env.SEED by default. You need to pass null explicitly if you only want to create transaction and not to sign it E.x.:

Console

constsignedTx=transfer({amount: 100,recipient: '3MyAGEBuZGDKZDzYn6sbh2noqk9uYHy4kjw',senderPublicKey: '8ViwGfvyyN1teUKV4Uvk2orK6XiYB4S4VuM2DqJ9Mj5b'},null)//returns tx with no proofs{"type": 4,"version": 2,"fee": 100000,"senderPublicKey": "8ViwGfvyyN1teUKV4Uvk2orK6XiYB4S4VuM2DqJ9Mj5b","timestamp": 1542640481876,"proofs": [],"id": "CveeKH16XQcshV5GZP2RXppg3snxcKqRsM4wE5gxcuzc","chainId": "T","amount": 100,"recipient": "3MyAGEBuZGDKZDzYn6sbh2noqk9uYHy4kjw"}

Additional functions

Broadcast signed tx using node from global variable

constresp=awaitbroadcast(signedTx)

Deploy current open contract using node from global variable

constresp=deploy()

Sign arbitrary transaction

consttx=transfer({amount: 100,recipient: '3MyAGEBuZGDKZDzYn6sbh2noqk9uYHy4kjw',senderPublicKey: '8ViwGfvyyN1teUKV4Uvk2orK6XiYB4S4VuM2DqJ9Mj5b'},null)constsignedTx=signTx(tx)

Compile contract. Returns base64

constcompiled=compile(contractText)

Get contract text by tab name. Used inside web-ide or vscode plugin

constcontractText=file(tabName)

Get contract text from currently open tab. Used inside web-ide or vscode plugin

constcontractText=contract()

Keys

address(seed=env.SEED)// Address from seed. keyPair(seed=env.SEED)// Keypair from seedpublicKey(seed=env.SEED)// Public key from seedprivateKey(seed=env.SEED)// Private key from seed

Global object env

env.SEED// Default seedenv.CHAIN_ID// Default network byteenv.API_BASE// Node url env.editors// Open editor tabs info

Usage

Dev server:

npm start
