Installation

yarn add -D @horizonx/aptos-codegen
yarn add @horizonx/aptos-module-client

or

npm install --save-dev @horizonx/aptos-codegen
npm install @horizonx/aptos-module-client

Usage

CLI

aptos-codegen -m {module(s)} -o {output-dir} -u {node-url}

or

aptos-codegen -c {configuration-file}

Options

| Option(*Required) | Description | Examples | | ------------------ | ------------------------------------------------------------------------ | ------------------------------------------------------ | | -m* | Module identifier(s). | 0x1::coin, 0x1::coin 0x1::account | | -o* | Output generated code to this directory. | __generated__ | | -u* | Aptos node URL. | https://fullnode.devnet.aptoslabs.com/v1 | | -f | ABI file path pattern(s) (glob). (*1) | abi/**/*.json | | -a | Directory name alias(es) of an address for duplicate name modules. (*2) | 0x1=framework | | -t | Generation target(s) of code. entryFunctions/getters/utilities | entryFunctions, entryFunctions utilities | | --minify-abi | Minify ABI output to factory. | - | | -c | Read options from this configuration file. (*3) | ./aptos-codegen.json (example) |

*1: ABIs loaded from files are referenced in preference to those loaded from the chain.

*2: By default, files are output to address dir if a duplicate name module is included.

*3: Configuration can be overwritten by arguments.

Factory of Module Interface

| Function | Description | Arguments | | -------- | ---------------------------------- | -------------------------------------------- | | connect | creates the module client instance | signerOrClient: AptosClient or Signer(*1) |

*1 Signer is a implementation of signAndSubmitTransaction: (payload, options) => Promise<string | { hash: string }>,
such as aptos-wallet-connector or aptos-wallet-adapter.

import { CoinModuleFactory } from './__generated__/CoinModuleFactory'

const coin = CoinModuleFactory.connect(signerOrClient)

// You can overwrite address of module
const coin = CoinModuleFactory.connect(signerOrClient, "0xAnotherAddress")

Utils of Module

| Function | Description | Arguments | | -------- | ---------------------------- | ------------------------ | | isXXX | a type guard of the resource | resource: MoveResource |

Common Utils

| Function | Description | Arguments | | --------------------- | --------------------------------------------------- | ------------------------- | | extractTypeParameters | extract type parameters string of the resource type | type: MoveResource.type | | typeToString | convert parsed type to string | type: ParsedType | | parseTypeStr | parse type str | type: MoveResource.type |
