The Fetcher package provides a simplified client interface to communicate with a Rosetta server. It also provides automatic retries and concurrent block fetches.
If you want a lower-level interface to communicate with a Rosetta server, check out the Client.
go get github.com/coinbase/rosetta-sdk-go/fetcherCreating a basic Fetcher is as easy as providing a context and Rosetta server URL:
fetcher := fetcher.New(ctx, serverURL)It is also possible to provide a series of optional arguments that override default behavior. For example, it is possible to override the concurrency for making block requests:
fetcher := fetcher.New(ctx, serverURL, fetcher.WithBlockConcurrency(10))Check out the examples to see how easy it is to connect to a Rosetta server.
