@laborx/typechain-truffle-target v0.2.6

Truffle typechain target

Custom target plugin for TypeChain or other origin at gitlab.

Details

Provides generation of typescript interfaces for Ethereum smart contracts. Basic types are mostly standing on @machinomy/types-web3 and @truffle-types/web3 packages for Truffle 4 or @types/web3 and @truffle-types/typescript-types packages for Truffle 5.

Configuration

To use this target etheir from CLI or configuration file you should at first create a script file with content

Truffle 4

const { Truffle } = require("typechain-truffle-target");

module.exports = ctx => {
  return new Truffle(ctx);
};

Truffle 5

const { TruffleV5 } = require("typechain-truffle-target");

module.exports = ctx => {
  return new TruffleV5(ctx);
};

There you could perform any presetup or preconfiguration as you like.

CLI

Then using:

typechain --target=[path to previous script] [glob]

For example:

typechain --target=./load-custom-plugin --outDir types typescript-contracts './build/contracts/*.json'

Config file

Then create or append to file ts-generator.json the next object:

[
	{
		"generator": "typechain",
		"target": "./load-custom-plugin",
		"files": "./build/contracts/*.json",
		"outDir": "./types",
		"declareModule": "truffle-contracts",
		"bigNumberType": "BigNumber"
	}
]

where

• "generator" - name of typechain generator;
• "target - created custom script file with target instantiation;
• "files" - glob pattern where to look for input files (contract artifacts in our case);
• "declareModule" - name of module declaration for created interfaces. By default uses truffle-contracts module name; it is also influences out directory name for contracts interfaces;
• "outDir" - place where results will be saved. By default it will save into ./types with two subdirectories: truffle-contracts and truffle;
• "bigNumberType" - (only for Truffle 5) type of bignumber "BigNumber" or "BN";

Then run

ts-generator ./ts-generator.json

# or

npx ts-generator ./ts-generator.json

Module name renaming works **ONLY** with configuration file.

And do not forget to add created directory either to include or typeRoots in tsconfig.json.
