Truffle – How to Get the Contract JSON Interface?

contract-developmentjson-rpctruffle

I'm developing smart contracts using Truffle. I got the contract's bytecode through truffle compile. This produced a large json file and it wasn't too ahrd to find the bytecode. Now, how can I find the Contract JSON Interface for easy testing of the contract, especially those that import from multiple files and so on?

Look for the object called abi: {}. It might be huge.

I agree with Mikko Ohtamaa. Do it through an API that wraps the JSON-RPC calls for you. However, to answer your question, I believe "eth_getTransactionReceipt" is the RPC call your looking for. It delivers an Array "logs" which should contain the fired events.

[Ethereum] How to specify a different Solidity version in a Truffle contract

In Truffle version 5.0.0 (currently in Beta) you can specify a Solidity version in the truffle.js config file eg

module.exports = {
  networks: {
    ... etc ...
  },
  compilers: {
     solc: {
       version: <string>  // ex:  "0.4.20". (Default: Truffle's installed solc)
     }
  }
};
