httpc VS hedera-json-rpc-relay

If you don't use any framework, I recommend you look httpc which allows you to write functions as API calls. And comes with nice centralized error handling.

Would you like to give a look at httpc?

If you more keen on natural or functional JavaScript, you can checkout httpc which integrates natively with a validator so you can define your models to have input parameters validated. Checkout the validation page and the section class-validator where you can define models and properties with any validation.

I would like to integrate the validator with httpc, an API framework with pluggable validators. I need some guidance, as it seems it doesn't support generic calls: ts validate(object: unknown): T { // validate here } Is there a way to define a schema or something, or you need to be explicit with the exact type with any validation call?

httpc is a framework for building function-based API with minimal code and end-to-end type safety. In addition to rpc-style requests, an httpc server can treat any http request as a function call, allowing to handle browser forms, webhooks callbacks and so on.

If you have time you can check httpc, that I recently released to build API with a function-based approach. The docs show how to use JWT too. Any feedback is appreciated.

For now documentation covers initial steps and basic scenarios. Full documentation is working in progress, as there're lots of areas to cover. Head to issues or discussions for any info or requests.

For developers to utilize the relay, Swirlds Labs released a beta implementation called Hashio. It lets you make RPC calls to the Hedera network and run EVM-based applications. Developer tools, such as Hardhat, Truffle, Web3.js and Ethers, as well as Metamask, can be used with the relay — tools available to use with the relay can are found here.
