mesh-sdk-go generates a Golang server and client package for the Mesh Data API using the OpenAPI 3.0 Mesh API Spec. To get started with the SDK, we recommend taking a look at the mesh-cli repository, which provides extensive usage examples.

​
Packages

mesh-sdk-go contains a lot of additional functionality that Coinbase built to make interacting with Mesh Data API implementations easier. If you have ideas for other packages, please open an issue!

​
Types

Types contains all generated Mesh Data API types.

​
Client

Client is the standard generated client for the Mesh Data API. The fetcher package builds on the low-level client to provide automatic retries and multi-threaded block fetching.

​
Server

Server makes implementation of the Mesh Data API as easy as implementing an interface. All boilerplate code to validate and route requests is provided out-of-the-box.

​
Fetcher

Simplified and validated communication with any Mesh server

​
Asserter

Asserter is used by the server and fetcher packages to validate that requests and responses, respectively, are well-formed.

​
Parser

Parser provides a collection of helpers to make block parsing easier. The parser can calculate all balance changes in a block, group related operations, and match an operation description with an operation in a transaction.

​
Syncer

Syncer is a blockchain-agnostic tool used to serially sync blocks from a Mesh Data API implementation (automatically handles re-orgs). For example, you could use the syncer to build a block explorer for any blockchain and not need to write any of your own logic to fetch blocks from a Mesh Data API implementation. The syncer is not tightly coupled to a storage backend or block-handling logic so it is possible for any developer to bring their own database for syncing and write their own logic to handle synced blocks.

​
Reconciler

Reconciler is used (often in conjunction with syncer) to compare the balance computed exclusively from transaction operations with the balance returned by a Data API implementation at various heights (erroring if the “computed” and “live” balance differ).

​
Keys

Keys provides an implementation of cryptographic operations for Mesh-supported curves.

​
SDKs in Other Languages

Currently, we support the Golang SDK.
If you build an SDK for a different language while implementing the Mesh APIs, reach out to rosetta@coinbase.com so that we can feature it in the mesh-ecosystem repository.
