Remix makes it so easy to get the json abi code.
Does anyone have any recommendation on how best to get he json abi code after successfully deploying a contract using truffle without having to leverage Remix?
Thank you in advance!
when you run
$ truffle compile
truffle creates and saves a json file per contract in
/yourProjectPath/build/contracts. In this json file you'll find the abi, the bytecode, the topics (if you have any
event in your smart contract), the function definitions etc (you get the point I guess, I encourage you to spend some time understanding that file - just to get a broad understanding).
personally I use python for my projects. Here is how I automatically load my abi into my scripts for transacting with my contracts (using web3py)
import json PATH_TRUFFLE_WK = '/home/myUserName/Projects/myEthereumProjet/' truffleFile = json.load(open(PATH_TRUFFLE_WK + '/build/contracts/myContractName.json')) abi = truffleFile['abi'] bytecode = truffleFile['bytecode']
You can do the same with your favorite programming language or simply copying-pasting your abi by hand.
I wrote a simple tool that does exactly what @salanfe suggested. It's handy when you have multiple contract definitions:
# Install it from npm $ npm install -g truffle-export-abi # Run it in your truffle project $ truffle-export-abi ABI extracted and output file wrote to: build/ABI.json
