Command line tool to create a TypeScript strictly typed interface from an Ethereum ABI. This is a a developer tool for typ3 to allow for type inferencing.

To install typ3-cli use npm install -g typ3-cli

To use this development tool, compile an Ethereum contract into an ABI, then call typ3-cli -f ./path/to/file -o ./output/file to generate the typed interface file. The interface in this file can then be imported to provide type-inferencing.

typ3-cli -f ./dist/auction.json

or with optional -o

typ3-cli -f ./auction.json -o ./auctionTypes.ts

Then to import the typed interface,

import { IAuction, IConnectedAuction } from './auctionTypes'

This will allow your code editor to auto generate the functions and properties from your ABI

An additional filename.output.ts file can be placed in the same folder as the ABI file to map names to unnamed output results from the ABI. The file should look like this:

// auction.output.ts
module.exports = {
    resolver: ["resolverAddress"],
    owner: ["ownerAddress"],
    ttl: ["timeToLive"]
};

where each key is the name of a function, and the value is the name to map to the result.

Multiple output files can be specified when there are multiple input files, to print each type definition to a specific file. Example usage:

typ3-cli -f ./testABIs/auction.json ./testABIs/ERC20.json -o ./auction.ts ./erc20.ts
