Question 1

How to securely sign transactions with eosjs in a production environment?

Accepted Answer

Avoid the JsSignatureProvider and integrate with secure external solutions like hardware wallets or server-side key management systems, as the README warns it's for development only. This requires additional setup and security audits.

Question 2

eosjs vs ethers.js for blockchain development?

Accepted Answer

eosjs is specifically for EOSIO blockchains, while ethers.js targets Ethereum; choose eosjs if you're building on EOSIO, but for multi-chain projects, you'll need separate libraries or a more generic solution.

Question 3

How to set up eosjs with TypeScript in a Node.js project?

Accepted Answer

Install eosjs and @types/text-encoding as dev dependencies, then update your tsconfig.json to include the 'dom' lib, as detailed in the README. This ensures proper type definitions and avoids compilation errors.

Question 4

Can eosjs be used with React for building dApp frontends?

Accepted Answer

Yes, but you must handle the browser build step or use a bundler like webpack, and implement secure signing outside the client, such as through wallet integrations, to prevent key exposure.

Question 5

How does eosjs handle RPC errors when transactions fail?

Accepted Answer

It provides an RpcError class for structured error handling; catch exceptions and use JSON.stringify on e.json to get detailed error information, as shown in the Error Handling example for debugging.

Question 6

What are the alternatives to eosjs for EOSIO development?

Accepted Answer

Community libraries like eosjs-ng or direct RPC calls exist, but eosjs is the official option with comprehensive features and documentation. Evaluate based on your project's needs for stability and support.
