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
``ts
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 =

my-counter blob:

Hex:

${hex}

Buffer:

${blobBuf}

Base64:

${base64Data}

Hash:

${hash}

}

const app = document.querySelector('#app')!
startWasiTask(app)
`

* Disassemble contract example
`ts
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 =

disassemble status: ${ok}

disassembled code:

${data}

})
}

const app = document.querySelector('#app')!
startDisassembleTask(app)
`

Supported Rust Versions

@movefuns/move-js supports the version of Rust (toolchain and targets) specified

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

Build the source

`
yarn install
yarn build
`
