Acurast SDK

Programmatic SDK for interacting with the Acurast Cloud.

@acurast/sdk is the main entry point for developers who want to deploy and manage deployments on Acurast from TypeScript/JavaScript. It bundles everything needed to upload a project to IPFS, register a job on-chain, match it with processors, and manage deployments.

Installation

$ npm install @acurast/sdk

The SDK relies on @polkadot/* packages as peer dependencies:

$ npm install @polkadot/api @polkadot/api-augment @polkadot/keyring \
              @polkadot/types @polkadot/types-codec @polkadot/util \
              @polkadot/util-crypto @polkadot/wasm-crypto

Modules

The SDK is split into subpath exports so you can import only the parts you need.

@acurast/sdk/deploy

High-level deployment utilities. Zip a local project, upload it to IPFS, and register the job on the Acurast chain in a single call.

import { deployProject, loadAcurastConfig } from '@acurast/sdk/deploy'

const config = await loadAcurastConfig('./acurast.json')
await deployProject({ config /* ... */ })

Also exports zipFolder, createManifest, checkIsFolder, and a Logger interface with a NOOP_LOGGER default.

@acurast/sdk/chain

Direct access to the Acurast chain: wallets, balances, job registration, assignments, environment variables, and app versions.

import {
  walletFromMnemonic,
  getBalance,
  registerJob,
  jobAssignments,
  AcurastService,
  setEnvVars
} from '@acurast/sdk/chain'

Helpers include convertConfigToJob, duration constants (second, minute, hour, day), sensible defaults (DEFAULT_REWARD, DEFAULT_REPLICAS, ...), the JobEnvironmentService for encrypted env vars, and an InMemoryKeyStore.

@acurast/sdk/ipfs

Upload deployment scripts to IPFS.

import { uploadScript } from '@acurast/sdk/ipfs'

const cid = await uploadScript({
  /* IpfsUploadOptions */
})

@acurast/sdk/matcher

Pricing and matching helpers for jobs: check whether a job has matching processors, analyze fees, and get pricing advice.

import {
  checkMatch,
  checkMatchWithReward,
  getAveragePrice,
  getPriceDistribution,
  getProcessorCount,
  suggestCostPerExecution,
  getFeeAnalysis,
  analyzePricing,
  fetchPricingAdvice
} from '@acurast/sdk/matcher'

@acurast/sdk/types

Shared TypeScript types used across the SDK.

Runtimes

Set runtime on AcurastProjectConfig to pick the execution environment:

• DeploymentRuntime.NodeJSWithBundle (default) — Node.js, bundled file deployment.
• DeploymentRuntime.NodeJS — Node.js, single-file deployment.
• DeploymentRuntime.Shell — native binary inside a Linux distro image (PRoot-isolated). Requires image: { url, sha256 } on the config; the SDK auto-adds RequiredModules.Shell to requiredModules and embeds the image reference in manifest.json.

import { DeploymentRuntime } from '@acurast/sdk/types'

const config = {
  runtime: DeploymentRuntime.Shell,
  entrypoint: 'acurast.sh',
  image: {
    url: 'https://github.com/termux/proot-distro/releases/download/v4.30.1/ubuntu-questing-aarch64-pd-v4.30.1.tar.xz',
    sha256: '5ab35b90cd9a9f180656261ba400a135c4c01c2da4b74522118342f985c2d328',
  },
  // ...
}
