# deploy

The deploy function stores an ES6 module on the blockchain and returns an identifier for that module. This identifier can be passed into the functions computer.new, computer.encode, computer.encodeNew, and computer.encodeCall to make the exports of the module available there.

The advantage of deploying your code is that it can save transaction fees: A large piece of code can be deployed once and then used to create or update many smart objects.

(module: string) => Promise<string>

const rev = await computer.deploy(exp)

A string encoding an ES6 module.

A string encoding the location where the module is stored. The format is <transaction id>:<output number>.

const revA = await computer.deploy(
  `export class A extends Contract {}`
)

const revB = await computer.deploy(`
  import { A } from '${revA}'
  export class B extends A {}
`)

const transition = { exp: `new B()`, mod: revB }
const tx = await computer.encode(transition)
