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();

TypeDocs

See typedocs.

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.

1. Run a local Haveno test network and then shut down the arbitrator, Alice, and Bob or run them as daemons, e.g. make alice-daemon. You may omit the arbitrator registration steps since it is 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. In a new terminal, start envoy with the config in haveno-ts/config/envoy.test.yaml (change absolute path for your system): docker run --rm --add-host host.docker.internal:host-gateway -it -v ~/git/haveno-ts/config/envoy.test.yaml:/envoy.test.yaml -p 8079:8079 -p 8080:8080 -p 8081:8081 -p 8082:8082 -p 8083:8083 -p 8084:8084 -p 8085:8085 -p 8086:8086 envoyproxy/envoy-dev:8a2143613d43d17d1eb35a24b4a4a4c432215606 -c /envoy.test.yaml
4. In a new terminal, start the funding wallet. This wallet will be automatically funded in order to fund Alice and Bob during the tests.
   For example: cd ~/git/haveno && make funding-wallet.
5. Install protobuf compiler v3.19.1 or later for your system:
   mac: brew install protobuf
   linux: apt install protobuf-compiler NOTE: You may need to upgrade to v3.19.1 manually if your package manager installs an older version.
6. Download protoc-gen-grpc-web plugin and make executable as shown here.
7. cd haveno-ts
8. npm install
9. npm test to run all tests or npm run test -- -t 'my test' to run tests by name.
