Package Exports
- abi-decoder-tool
- abi-decoder-tool/dist/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (abi-decoder-tool) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

abi-decoder typescript
Nodejs and Typescript library for decoding data params and events from ethereum transactions
Instantiate
const abiDecoder = new AbiDecoder();Add ABI's
Need to pass the ABI's manually to the library in order to be able to decode params later
