Convert an ABI to a Solidity interface
$ npm install --save abi2solidity
# OR
$ yarn add abi2solidityIf you want to use the cli, you can install it globally:
$ npm install --global abi2solidity
# OR
$ yarn global add abi2solidity$ abi2solidity -h
Usage: abi2solidity [options]
Options:
-V, --version output the version number
-i, --input <file> JSON ABI Input file (default: "")
-o, --output <file> Solidity output file (default: "")
-e, --header <string> Set the header (default: "")
-n, --interface-name <string> Set the interface name (default: "GeneratedInterface")
-h, --help display help for command
# Examples
$ abi2solidity -i abi.json -o export.sol
$ abi2solidity --header "" --interface-name McNulty < test/abi/SmolTest.abi
$ abi2solidity --header "" --interface-name McNulty < test/abi/SmolTest.abi
$ abi2solidity --header "`printf "// SPDX-License-Identifier: MIT\\npragma solidity >=0.1.0 <0.9.0;\n "`" --interface-name McNulty < test/abi/SmolTest.abiimport ABI2solidity from "abi2solidity";
