@aeternity/contract-builder

This package simplifies contract preparation to be used in production by providing:

• a webpack loader to import .aes files directly to JavaScript modules;
• a CLI tool called ae-contract-builder to be used if webpack is not available or not configurable.

Usage guide

Installation

Firstly, you need to add this package to your project

$ npm install @aeternity/contract-builder --save-dev

To use aesophia_cli (enabled by default), escript needs to be available in PATH.

Setup as a webpack loader

Add the loader to your webpack config. For example:

webpack.config.js

module.exports = {
  module: {
    rules: [{
+      test: /\.aes$/,
+      use: [{
+        loader: `@aeternity/contract-builder`,
+        options: {
+          compilerType: 'http', // or 'cli'
+          compilerPath: './foo/aesophia_cli',
+          compilerUrl: 'http://localhost:3080/',
+          // the above is optional, uses CLI compiler by default
+        },
      }],
    }],
  },
};

And run webpack via your preferred method.

Use as a separate tool

To build a smart contract into JavaScript module use

$ npx ae-contract-builder <path-to-contract-source.aes>

Also, you can add --watch flag to watch for smart contract changes, specify multiple contracts one by one, or add this script to package.json.

The output file will be located in the same directory with .js extension instead of .aes.

Output format

In both cases, you would get a Contract's child class with inlined ACI and compiled bytecode. It can be used the same as Contract class but not needed to provide aci, bytecode, or sourceCode.

import MyContract from './MyContract.aes';
// or import MyContract.js in case using ae-contract-builder

const myContract = await MyContract.initialize(aeSdk._getOptions());
await myContract.$deploy()
await myContract.foo('arg1', 'arg2')

Examples

• webpack loader in Vue CLI
• ae-contract-builder in bare Node project
