move-js

Javascript version of the move language compiler and disassemble

Features

  • Compiling move package into blob
  • Disassemble contract

Example

  • Compiling move package into blob example
import { WasmFs } from '@wasmer/wasmfs'
import { Git, MovePackage } from '@movefuns/move-js'

const startWasiTask = async (app: HTMLDivElement) => {
  const wasmfs = new WasmFs()
  const git = new Git(wasmfs)

  await git.download("/data/framework.zip", "/workspace/framework")
  await git.download("/data/my-counter.zip", "/workspace/my-counter")

  const mp = new MovePackage(wasmfs, {
    packagePath: "/workspace/my-counter",
    test: false,
    alias: new Map([
      ["AptosFramework", "/workspace/framework/aptos-framework"]
    ]),
    initFunction: "0xABCDE::MyCounter::init"
  })

  await mp.build()

  const blobBuf = wasmfs.fs.readFileSync("/workspace/my-counter/target/aptos/release/package.blob")
  const hash = wasmfs.fs.readFileSync("/workspace/my-counter/target/aptos/release/hash.txt")
  const base64Data = blobBuf.toString("base64")

  // get hex of blob buf with 0x prefix
  const hex = blobBuf.toString("hex").replace(/^/, "0x")

  app.innerHTML = `
      <h1>my-counter blob:</h1>
      <dl>
        <dt>Hex:</dt><dd>${hex}</dd>
        <dt>Buffer:</dt><dd>${blobBuf}</dd>
        <dt>Base64:</dt><dd>${base64Data}</dd>
        <dt>Hash:</dt><dd>${hash}</dd>
      </dl>
    `
}

const app = document.querySelector<HTMLDivElement>('#app')!
startWasiTask(app)
  • Disassemble contract example
import { WasmFs } from '@wasmer/wasmfs'
import { Disassemble } from '@movefuns/move-js'

const startDisassembleTask = async (app: HTMLDivElement) => {
  const wasmfs = new WasmFs()

  const dp = new Disassemble(wasmfs)

  //Chain code
  const account_scripts = "your code"

  dp.disassemble("account_scripts", account_scripts, (ok: boolean, data: string) => {
    app.innerHTML = `
      <h1>disassemble status: ${ok}</h1>
      <h1>disassembled code:</h1>
      ${data}
    `
  })
}

const app = document.querySelector<HTMLDivElement>('#app')!
startDisassembleTask(app)

Supported Rust Versions

@movefuns/move-js supports the version of Rust (toolchain and targets) specified in rust-toolchain.toml. At the time of writing, we are using version 1.77.0. However, this can change at any time if one of our dependencies changes MSRV or through a new patch version.

Building from source

Note: You will need rust installed also for this. https://www.rust-lang.org/tools/install or

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Then get @movefuns/move-js source:

git clone https://github.com/movefuns/move-js
cd move-js
git checkout aptos

Build the source

yarn install
yarn build

Testing

my-counter (Compiling move package into blob)

cd example/my-counter/
yarn install
yarn dev

disassemble (Disassemble contract from bytecode)

cd example/disassemble
yarn install
yarn dev

Unit test

yarn test
