The SDK is provided in both CommonJS and ESM formats, and it's compatible with bundlers such as Webpack, Rollup, and ESbuild. Utilize the appropriately named exports provided by this SDK's package.json based on your project's configuration. Refer to the examples directory to see how to use the SDK in various environments.
CommonJS:
import { TurboFactory } from '@ardrive/turbo-sdk';
const turbo = TurboFactory.unauthenticated();
const rates = await turbo.getFiatRates();
Warning
Polyfills are not provided by default for bundled web projects (Vite, ESBuild, Webpack, Rollup, etc.) . Depending on your apps bundler configuration and plugins, you will need to provide polyfills for various imports including crypto
, process
, fs
and buffer
. Refer to your bundler's documentation for how to provide the necessary polyfills.
ESM:
import { TurboFactory } from '@ardrive/turbo-sdk/<node/web>';
const turbo = TurboFactory.unauthenticated();
const rates = await turbo.getFiatRates();
<script type="module">
import { TurboFactory } from 'https://unpkg.com/@ardrive/turbo-sdk';
const turbo = TurboFactory.unauthenticated();
const rates = await turbo.getFiatRates();
</script>
Example available in the examples/typescript/cjs.
Example available in the examples/typescript/esm.
The SDK provides TypeScript types. When you import the SDK in a TypeScript project:
import { TurboFactory } from '@ardrive/turbo-sdk/<node/web>';
Types are exported from ./lib/types/[node/web]/index.d.ts
and should be automatically recognized, offering benefits such as type-checking and autocompletion.
Examples are available in the examples directory. To run examples:
yarn example:web
- opens up the example web pageyarn example:cjs
- runs example CJS node scriptyarn example:esm
- runs example ESM node script
The SDK uses winston for logging. You can set the log level using the setLogLevel
method.
TurboFactory.setLogLevel('debug');

},
],
// no timeout or AbortSignal provided
},
});
uploadFolder({ folderPath, files, dataItemOpts, signal, maxConcurrentUploads, throwOnFailure, manifestOptions })
Signs and uploads a folder of files. For NodeJS, the folderPath
of the folder to upload is required. For the browser, an array of files
is required. The dataItemOpts
is an optional object that can be used to configure tags, target, and anchor for the data item upload. The signal
is an optional AbortSignal that can be used to cancel the upload or timeout the request. The maxConcurrentUploads
is an optional number that can be used to limit the number of concurrent uploads. The throwOnFailure
is an optional boolean that can be used to throw an error if any upload fails. The manifestOptions
is an optional object that can be used to configure the manifest file, including a custom index file, fallback file, or whether to disable manifests altogether. Manifests are enabled by default.
const folderPath = path.join(__dirname, './my-folder');
const { manifest, fileResponses, manifestResponse } = await turbo.uploadFolder({
folderPath,
dataItemOpts: {
// optional
tags: [
{
// User defined content type will overwrite file content type
name: 'Content-Type',
value: 'text/plain',
},
{
name: 'My-Custom-Tag',

Tops up the connected wallet with Credits by submitting a payment transaction for the token amount to the Turbo wallet and then submitting that transaction id to Turbo Payment Service for top up processing.
- The
tokenAmount
is the amount of tokens in the token type's smallest unit value (e.g: Winston for arweave token type) to fund the wallet with. - The
feeMultiplier
(optional) is the multiplier to apply to the reward for the transaction to modify its chances of being mined. Credits will be added to the wallet balance after the transaction is confirmed on the given blockchain. Defaults to 1.0, meaning no multiplier.
const turbo = TurboFactory.authenticated({ signer, token: 'arweave' });
const { winc, status, id, ...fundResult } = await turbo.topUpWithTokens({
tokenAmount: WinstonToTokenAmount(100_000_000), // 0.0001 AR
feeMultiplier: 1.1, // 10% increase in reward for improved mining chances
});
const turbo = TurboFactory.authenticated({ signer, token: 'ethereum' });
const { winc, status, id, ...fundResult } = await turbo.topUpWithTokens({
tokenAmount: ETHToTokenAmount(0.00001), // 0.00001 ETH
});
const turbo = TurboFactory.authenticated({ signer, token: 'pol' });
const { winc, status, id, ...fundResult } = await turbo.topUpWithTokens({
tokenAmount: POLToTokenAmount(0.00001), // 0.00001 POL
});
const turbo = TurboFactory.authenticated({ signer, token: 'solana' });
const { winc, status, id, ...fundResult } = await turbo.topUpWithTokens({
tokenAmount: SOLToTokenAmount(0.00001), // 0.00001 SOL
});
const turbo = TurboFactory.authenticated({ signer, token: 'kyve' });
const { winc, status, id, ...fundResult } = await turbo.topUpWithTokens({
tokenAmount: KYVEToTokenAmount(0.00001), // 0.00001 KYVE
});

Users can share their purchased Credits with other users' wallets by creating Credit Share Approvals. These approvals are created by uploading a signed data item with tags indicating the recipient's wallet address, the amount of Credits to share, and an optional amount of seconds that the approval will expire in. The recipient can then use the shared Credits to pay for their own uploads to Turbo.
Shared Credits cannot be re-shared by the recipient to other recipients. Only the original owner of the Credits can share or revoke Credit Share Approvals. Credits that are shared to other wallets may not be used by the original owner of the Credits for sharing or uploading unless the Credit Share Approval is revoked or expired.
Approvals can be revoked at any time by similarly uploading a signed data item with tags indicating the recipient's wallet address. This will remove all approvals and prevent the recipient from using the shared Credits. All unused Credits from expired or revoked approvals are returned to the original owner of the Credits.
To use the shared Credits, recipient users must provide the wallet address of the user who shared the Credits with them in the x-paid-by
HTTP header when uploading data. This tells Turbo services to look for and use Credit Share Approvals to pay for the upload before using the signer's balance.
For user convenience, during upload the Turbo CLI will use any available Credit Share Approvals found for the connected wallet before using the signing wallet's balance. To instead ignore all Credit shares and only use the signer's balance, use the --ignore-approvals
flag. To use the signer's balance first before using Credit shares, use the --use-signer-balance-first
flag. In contrast, the Turbo SDK layer does not provide this functionality and will only use approvals when paidBy
is provided.
The Turbo SDK provides the following methods to manage Credit Share Approvals:
shareCredits
: Creates a Credit Share Approval for the specified wallet address and amount of Credits.revokeCredits
: Revokes all Credit Share Approvals for the specified wallet address.listShares
: Lists all Credit Share Approvals for the specified wallet address or connected wallet.dataItemOpts: { ...opts, paidBy: string[] }
: Upload methods now accept 'paidBy', an array of wallet addresses that have provided credit share approvals to the user from which to pay, in the order provided and as necessary, for the upload.
The Turbo CLI provides the following commands to manage Credit Share Approvals:
share-credits
: Creates a Credit Share Approval for the specified wallet address and amount of Credits.revoke-credits
: Revokes all Credit Share Approvals for the specified wallet address.list-shares
: Lists all Credit Share Approvals for the specified wallet address or connected wallet.paidBy: --paid-by <paidBy...>
: Upload commands now accept '--paid-by', an array of wallet addresses that have provided credit share approvals to the user from which to pay, in the order provided and as necessary, for the upload.--ignore-approvals
: Ignore all Credit Share Approvals and only use the signer's balance.--use-signer-balance-first
: Use the signer's balance first before using Credit Share Approvals.
