For example, the gRPC function to get offers is implemented by [`GrpcServer`](https://github.com/haveno-dex/haveno/blob/master/daemon/src/main/java/haveno/daemon/grpc/GrpcServer.java) > [`GrpcOffersService.getOffers(...)`](https://github.com/haveno-dex/haveno/blob/b761dbfd378faf49d95090c126318b419af7926b/daemon/src/main/java/haveno/daemon/grpc/GrpcOffersService.java#L104) > [`CoreApi.getOffers(...)`](https://github.com/haveno-dex/haveno/blob/b761dbfd378faf49d95090c126318b419af7926b/core/src/main/java/haveno/core/api/CoreApi.java#L128) > [`CoreOffersService.getOffers(...)`](https://github.com/haveno-dex/haveno/blob/b761dbfd378faf49d95090c126318b419af7926b/core/src/main/java/haveno/core/api/CoreOffersService.java#L126) > [`OfferBookService.getOffers()`](https://github.com/haveno-dex/haveno/blob/b761dbfd378faf49d95090c126318b419af7926b/core/src/main/java/haveno/core/offer/OfferBookService.java#L193).
6. Update the gRPC client in haveno-ts: `npm install`
7. Add the corresponding typescript method(s) to [haveno.ts](https://github.com/haveno-dex/haveno-ts/blob/master/src/haveno.ts) with clear and concise documentation.
8. Add clean and comprehensive tests to [haveno.test.ts](https://github.com/haveno-dex/haveno-ts/blob/master/src/haveno.test.ts), following existing patterns.
9. Run the tests with `npm run test -- -t 'my test'` to run tests by name and `npm test` to run all tests together. Ensure all tests pass and there are no exception stacktraces in the terminals of Alice, Bob, or the arbitrator.
