truffle-conflux-artifactor

This package saves contract artifacts into JSON files

const Artifactor = require("truffle-conflux-artifactor");
const artifactor = new Artifactor(__dirname);
artifactor.save({/*...*/}); // => a promise saving MyContract.json to a given destination

👏

Features

• Manages contract ABIs, binaries and deployed addresses, so you don't have to.
• Packages up build artifacts into .json files, which can then be included in your project with a simple require.
• Manages library addresses for linked libraries.

The artifactor can be used with truffle-conflux-contract, which provides features above and beyond web3:

• Synchronized transactions for better control flow: transactions won't be considered finished until you're guaranteed they've been mined.
• Promises. No more callback hell. Works well with ES6 and async/await.
• Default values for transactions, like from address or gas.
• Returning logs, transaction receipt and transaction hash of every synchronized transaction.

Install

$ npm install truffle-conflux-artifactor

Example

Here, we'll generate a .json files given a JSON object like truffle-conflux-contract-schema. This will give us a file which we can later require into other projects and contexts.

const Artifactor = require("truffle-conflux-artifactor");
const artifactor = new Artifactor(__dirname);

// See truffle-schema for more info: https://github.com/trufflesuite/truffle/tree/develop/packages/truffle-conflux-contract-schema
const contractData = {
  contractName: "...",        // String; optional.
  abi: ...,                   // Array; required.
  metadata: "...",            // String; optional.
  bytecode: "...",            // String; optional.
  "x-some-dependency": ...    // String, Number, Object, or Array: optional.
};

artifactor.save(contractData);
// The file ./MyContract.json now exists, which you can
// import into your project like any other Javascript file.

API

artifactor.save(contractData)

Save contract data as a .json file. Returns a Promise.

• contractData: Object. Data that represents this contract:

  {
    contractName: "MyContract",   // String; optional. Defaults to "Contract".
    abi: ...,                     // Array; required.  Application binary interface.
    metadata: "...",              // String; optional. Contract metadata.
    bytecode: "...",              // String; optional. Contract-creation binary without resolve library links.
    deployedBytecode: "...",      // String; optional. On-chain deployed binary without resolve library links.
    sourceMap: "...",             // String; optional. Source mapping for bytecode.
    deployedSourceMap: "...",     // String; optional. Source mapping for deployedBytecode.
    source: "...",                // String; optional. Uncompiled source code for contract.
    sourcePath: "...",            // String; optional. File path for uncompiled source code.
    ast: ...,                     // Object; optional. JSON representation of contract source code, as output by compiler.
    legacyAST: ...,               // Object; optional. Legacy JSON representation of contract source code, as output by compiler.
    compiler: ...,                // Object; optional. Compiler "type" and "properties".
    networks: ...,                // Object; optional. Mapping of network ID keys to network object values (address information, links to other contract instances, and/or contract event logs).
    schemaVersion: "...",         // String; optional. Schema version used by contract object representation.
    updatedAt: "...",             // String; optional. Time contract object representation was generated/most recently updated.
    devdoc: "...",                // String; optional. Developer documentation.
    userdoc: "...",               // String; optional. User documentation.
    "x-custom-property": ...      // String, Number, Object, or Array: optional. Custom property. Keys must be prefixed with "x-".
  }
  

artifactor.saveAll(contracts)

Save many contracts to the filesystem at once. Returns a Promise.

• contracts: Object. Keys are the contract names and the values are contractData objects, as in the save() function above:

  {
    "MyContract": {
      "abi": ...,
      "bytecode": "..."
    }
    "AnotherContract": {
      // ...
    }
  }
