Haveno TypeScript Library

TypeScript library for using Haveno.

Install

1. Start a Haveno daemon (see installing.md).
2. Install haveno-ts in your project: npm install haveno-ts

Sample code

import { HavenoClient } from "haveno-ts";

// create client connected to Haveno daemon
const alice = new HavenoClient("http://localhost:8080", "apitest");

// use Haveno daemon
const balances = await alice.getBalances();
const paymentAccounts = await alice.getPaymentAccounts();
const myOffers = await alice.getMyOffers("ETH");
const offers = await alice.getOffers("ETH", "BUY");
const trade = await alice.takeOffer(offers[0].getId(), paymentAccounts[0].getId());

// disconnect client
await alice.disconnect();

Run tests

Running the API tests is the best way to develop and test Haveno end-to-end. HavenoClient.ts provides the client interface to Haveno's backend daemon.

You first need to start a local Haveno network which can be done manually or using docker.

Start local Haveno network manually

This workflow is useful for local development of haveno and haveno-ts

1. Run a local Haveno test network and then shut down the arbitrator, user1, and user2 or run them as daemons, e.g. make user1-daemon-local. You may omit the arbitrator registration steps since it's done automatically in the tests.
2. Clone this project to the same parent directory as the haveno project: git clone https://github.com/haveno-dex/haveno-ts
3. Install envoy proxy from your package manager of choice, for example brew install envoy.
4. In a new terminal, start envoy with the config in haveno-ts/config/envoy.local.yaml: envoy -c config/envoy.local.yaml
5. In a new terminal, start the funding wallet. This wallet will be funded automatically in order to fund the tests.
   For example: cd ~/git/haveno && make funding-wallet-local.

Start local Haveno network with docker

Alternatively use this wokflow to develop haveno-ts or run tests with dockerized setup:

Start a local Haveno network with docker:

1. cd ~/git/haveno-ts/docker
2. sudo docker-compose up. This will start docker and initialize the network.

Docker Tips

• Stop: sudo docker-compose stop
• Rebuild: sudo docker-compose build
• Stop and delete contains: sudo docker-compose stop

Run client tests

5. Install protobuf compiler v3.20.3 for your system.
6. Download protoc-gen-grpc-web plugin and make executable as shown here.
7. cd haveno-ts
8. npm install
9. npm run test -- --baseCurrencyNetwork=XMR_LOCAL to run all tests or npm run test -- --baseCurrencyNetwork=XMR_LOCAL -t "Can get the version" to run tests by name.
