// }Usage
The SDK is provided in both CommonJS and ESM formats and is 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.
Web

The SDK provides TypeScript types. When you import the SDK in a TypeScript project types are exported from ./lib/types/[node/web]/index.d.ts and should be automatically recognized by package managers, offering benefits such as type-checking and autocompletion.
ArIO Contract
APIs
connect(signer)
Connects an ArweaveSigner or ArConnectSigner instance to the client for performing writeInteraction calls.
Supported only on clients configured with a WarpContract instance.
NOTE: if you have a client configured with a RemoteContract instance, it will be overriden with a WarpContract instance using the existing configuration of the RemoteContract instance when connect is executed.

// }Custom Contracts
The ArIO contract client class exposes APIs relevant to the ar.io contract. It can be configured to use any contract ID that adheres to the spec of the ar.io contract. In the default case, it will automatically build and utilize a contract data provider interface that is configured to point the the known mainnet contract ID at construction time. You can provide custom contract data provider or, alternatively, a contractTxId to the ArIO constructor to use a different, ar.io-spec-compatible contract.
// provide a custom contractTxId to the client and default to remote evaluation
const remoteCustomArIO = new ArIO({
contractTxId: 'TESTNET_CONTRACT_TX_ID',
});
// provide a custom contract to the client, and specify local evaluation using warp
const localCustomArIO = new ArIO({
contract: new WarpContract<ArIOState>({
contractTxId: 'TESTNET_CONTRACT_TX_ID',
}),
});
// provide a custom contract to the client, and specify local evaluation using remote cache
const remoteCacheCustomArIO = new ArIO({
contract: new RemoteContract<ArIOState>({
contractTxId: 'TESTNET_CONTRACT_TX_ID',
}),
});Arweave Name Tokens (ANT's)
The ANT contract client class exposes APIs relevant to compliant Arweave Name Token contracts. It can be configured to use any contract ID that adheres to the ANT contract spec. You must provide either a custom contract data provider or a contractTxId to the ANT class constructor to use.
APIs
connect(signer)
Connects an ArweaveSigner or ArConnectSigner instance to the client for performing writeInteraction calls.
Supported only on clients configured with a WarpContract instance.
NOTE: if you have a client configured with a RemoteContract instance, it will be overriden with a WarpContract instance using the existing configuration of the RemoteContract instance when connect is executed.
const ant = new ANT();
const browserSigner = new ArConnectSigner(window.arweaveWallet);
ant.connect(browserSigner);
const nodeSigner = new ArweaveSigner(JWK);
ant.connect(nodeSigner);getOwner({ evaluationOptions })
Returns the owner of the configured ANT contract.
const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
const ant = new ANT({ contractTxId });
const owner = await ant.getOwner();
// output: "bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM"getControllers({ evaluationOptions })
Returns the controllers of the configured ANT contract.
const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
const ant = new ANT({ contractTxId });
const controllers = await ant.getControllers();
// output: ["bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM"]getRecords({ evaluationOptions })
Returns all records on the configured ANT contract, including the required @ record that resolve connected ArNS names.
const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
const ant = new ANT({ contractTxId });
const records = await ANT.getRecords();
// output
// {
// "@": {
// "transactionId": "nOXJjj_vk0Dc1yCgdWD8kti_1iHruGzLQLNNBHVpN0Y",

// },
// "cn": {
// "transactionId": "_HquerT6pfGFXrVxRxQTkJ7PV5RciZCqvMjLtUY0C1k",
// "ttlSeconds": 3300
// }
// }Configuration
ANT clients can be configured to use custom contract evaluator. By default they will use the remote evaluator that leverages the arns-service.
// provide a contractTxId to the client and default to remote evaluation
const remoteANT = new ANT({
contractTxId: 'ANT_CONTRACT_TX_ID',
});
// provide a custom contract to the client, and specify local evaluation using warp
const warpEvaluatedANT = new ANT({
contract: new WarpContract<ANTState>({
contractTxId: 'ANT_CONTRACT_TX_ID',
}),
});
// provide a custom contract to the client, and specify local evaluation using remote cache
const remoteANTContract = new ANT({
contract: new RemoteContract<ANTState>({
contractTxId: 'ANT_CONTRACT_TX_ID',
// the remote api that returns warp compliant contract evaluation
url: 'https://api.arns.app/v1/contract',
}),
});Developers
