Abitty 👌

Abitty cherry-picks specific functions from your Solidity ABIs and saves them for individual importing. Stop using thicc JSON files, start shaking that tree.

Configuration

Create abitty.config.json in your project directory.

{
    "outputDir": "./src/types",
    "organize": true,
    "contracts": [
        {
            "name": "foo",
            "abiPath": "../out/Foo.sol/Foo.json",
            "pick": ["someFunction", "someOtherFunction", "amazingFunction"]
        },
        {
            "name": "bar",
            "abiPath": "../out/Bar.sol/Bar.json",
            "pick": ["excellentFunction"]
        }
    ]
}

Config spec

key		required
outputDir	Relative path where the generated files will go	Yes
organize	If true, organizes contract files in folders and creates a single entrypoint	No
contracts	An array of Contracts 👇	Yes
Contract.name	Used for generating folder names, required if organize is set to true	Sometimes
Contract.abiPath	Path to your Solidity build artifact's JSON file	Yes
Contract.pick	Functions you want to use	Yes

Generating your files

Install as a dev dependency and add to your package scripts

npm install abitty --save-dev

"scripts": {
    "gimme-them-abis": "abitty"
},

or skip this above and run with npx

npx abitty

The script will output an individual .ts file for each function, plus a helper type you can use to ensure arguments passed to that function satisfy the ABI.

If you are using a different configuration file, pass it to Abitty with the --config-file flag.

Using your exports

They work great with Viem / Wagmi which you should definitely be using.

import { doTheFooAbi, DoTheFooArgs } from 'yourOutputDir/foo/doTheFoo';

await publicClient.simulateContract({
    abi: [doTheFooAbi],
    address: fooAddress,
    functionName: 'doTheFoo',
    args: [myArg1, myArg2, myArg3],
    account: userAccount,
});

// You can use the generated argument typings like so:
const myArgs = [myArg1, myArg2, myArg3] satisfies DoTheFooArgs;
