# One TypeScript SDK

This is the One TypeScript SDK built on the Sui
[JSON RPC API](https://github.com/MystenLabs/sui/blob/main/docs/content/references/sui-api.mdx). It
provides utility classes and functions for applications to sign transactions and interact with the
Sui network.

WARNING: Note that we are still iterating on the RPC and SDK API before TestNet, therefore please
expect frequent breaking changes in the short-term. We expect the API to stabilize after the
upcoming TestNet launch.

## Working with Devnet

The SDK will be published to [npm registry](https://www.npmjs.com/package/@onelabs/sui) with the same
bi-weekly release cycle as the Devnet validators and
[RPC Server](https://github.com/MystenLabs/sui/blob/main/docs/content/references/sui-api.mdx). To
use the SDK in your project, you can do:

```bash
$ npm install @onelabs/sui
```

You can also use your preferred npm client, such as yarn or pnpm.

## Working with local network

Note that the `latest` tag for the [published SDK](https://www.npmjs.com/package/@onelabs/sui) might
go out of sync with the RPC server on the `main` branch until the next release. If you're developing
against a local network, we recommend using the `experimental`-tagged packages, which contain the
latest changes from `main`.

```bash
npm install @onelabs/sui@experimental
```

Refer to the
[JSON RPC](https://github.com/MystenLabs/sui/blob/main/docs/content/references/sui-api.mdx) topic
for instructions about how to start a local network and local RPC server.

## Building Locally

To get started you need to install [pnpm](https://pnpm.io/), then run the following command:

```bash
# Install all dependencies
$ pnpm install

# Run `build` for the TypeScript SDK if you're in the `sdk/typescript` project
$ pnpm run build

# Run `sdk build` for the TypeScript SDK if you're in the root of `sui` repo
$ pnpm sdk build
```

> All `pnpm` commands below are intended to be run in the root of the Sui repo.

## Type Doc

You can view the generated [Type Doc](https://typedoc.org/) for the
[current release of the SDK](https://www.npmjs.com/package/@onelabs/sui) at
http://typescript-sdk-docs.s3-website-us-east-1.amazonaws.com/.

For the latest docs for the `main` branch, run `pnpm doc` and open the
[doc/index.html](doc/index.html) in your browser.

## Testing

To run unit tests

```
pnpm --filter @onelabs/sui test:unit
```

To run E2E tests against local network

```
pnpm --filter @onelabs/sui prepare:e2e

// This will run all e2e tests
pnpm --filter @onelabs/sui test:e2e

// Alternatively you can choose to run only one test file
npx vitest txn-builder.test.ts
```

Troubleshooting:

If you see errors like `ECONNRESET or "socket hang up"`, run `node -v` to make sure your node
version is `v18.x.x`. Refer to this
[guide](https://blog.logrocket.com/how-switch-node-js-versions-nvm/) to switch node version.

Some more follow up here is if you used homebrew to install node, there could be multiple paths to
node on your machine.
https://stackoverflow.com/questions/52676244/node-version-not-updating-after-nvm-use-on-mac

To run E2E tests against Devnet

```
VITE_FAUCET_URL='https://faucet.devnet.sui.io:443/gas' VITE_FULLNODE_URL='https://fullnode.devnet.sui.io' pnpm --filter @onelabs/sui exec vitest e2e
```

## Connecting to Sui Network

The `SuiClient` class provides a connection to the JSON-RPC Server and should be used for all
read-only operations. The default URLs to connect with the RPC server are:

- local: http://127.0.0.1:9000
- Devnet: https://fullnode.devnet.sui.io

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';

// create a client connected to devnet
const client = new SuiClient({ url: getFullnodeUrl('devnet') });

// get coins owned by an address
await client.getCoins({
	owner: '0xcc2bd176a478baea9a0de7a24cd927661cc6e860d5bacecb9a138ef20dbab231',
});
```

For local development, you can run `cargo run --bin --with-faucet --force-regenesis` to spin up a
local network with a local validator, a fullnode, and a faucet server. Refer to
[this guide](https://docs.sui.io/build/sui-local-network) for more information.

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';

// create a client connected to devnet
const client = new SuiClient({ url: getFullnodeUrl('localnet') });

// get coins owned by an address
await client.getCoins({
	owner: '0xcc2bd176a478baea9a0de7a24cd927661cc6e860d5bacecb9a138ef20dbab231',
});
```

You can also construct your own in custom connections, with the URL for your own fullnode

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';

// create a client connected to devnet
const client = new SuiClient({
	url: 'https://fullnode.devnet.sui.io',
});

// get coins owned by an address
await client.getCoins({
	owner: '0xcc2bd176a478baea9a0de7a24cd927661cc6e860d5bacecb9a138ef20dbab231',
});
```

## Getting coins from the faucet

You can request sui from the faucet when running against devnet, testnet, or localnet

```typescript
import { getFaucetHost, requestSuiFromFaucetV0 } from '@onelabs/sui/faucet';

await requestSuiFromFaucetV0({
	host: getFaucetHost('testnet'),
	recipient: '0xcc2bd176a478baea9a0de7a24cd927661cc6e860d5bacecb9a138ef20dbab231',
});
```

## Writing APIs

For a primer for building transactions, refer to
[this guide](https://docs.sui.io/build/prog-trans-ts-sdk).

### Transfer Object

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';
import { Ed25519Keypair } from '@onelabs/sui/keypairs/ed25519';
import { Transaction } from '@onelabs/sui/transactions';

// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const client = new SuiClient({
	url: getFullnodeUrl('testnet'),
});

const tx = new Transaction();
tx.transferObjects(
	['0xe19739da1a701eadc21683c5b127e62b553e833e8a15a4f292f4f48b4afea3f2'],
	'0x1d20dcdb2bca4f508ea9613994683eb4e76e9c4ed371169677c1be02aaf0b12a',
);
const result = await client.signAndExecuteTransaction({
	signer: keypair,
	transaction: tx,
});
console.log({ result });
```

### Transfer Sui

To transfer `1000` MIST to another address:

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';
import { Ed25519Keypair } from '@onelabs/sui/keypairs/ed25519';
import { Transaction } from '@onelabs/sui/transactions';

// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const client = new SuiClient({
	url: getFullnodeUrl('testnet'),
});

const tx = new Transaction();
const [coin] = tx.splitCoins(tx.gas, [1000]);
tx.transferObjects([coin], keypair.getPublicKey().toSuiAddress());
const result = await client.signAndExecuteTransaction({
	signer: keypair,
	transaction: tx,
});
console.log({ result });
```

### Merge coins

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';
import { Ed25519Keypair } from '@onelabs/sui/keypairs/ed25519';
import { Transaction } from '@onelabs/sui/transactions';

// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const client = new SuiClient({
	url: getFullnodeUrl('testnet'),
});

const tx = new Transaction();
tx.mergeCoins('0xe19739da1a701eadc21683c5b127e62b553e833e8a15a4f292f4f48b4afea3f2', [
	'0x127a8975134a4824d9288722c4ee4fc824cd22502ab4ad9f6617f3ba19229c1b',
]);
const result = await client.signAndExecuteTransaction({
	signer: keypair,
	transaction: tx,
});
console.log({ result });
```

### Move Call

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';
import { Ed25519Keypair } from '@onelabs/sui/keypairs/ed25519';
import { Transaction } from '@onelabs/sui/transactions';

// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const client = new SuiClient({
	url: getFullnodeUrl('testnet'),
});
const packageObjectId = '0x...';
const tx = new Transaction();
tx.moveCall({
	target: `${packageObjectId}::nft::mint`,
	arguments: [tx.pure.string('Example NFT')],
});
const result = await client.signAndExecuteTransaction({
	signer: keypair,
	transaction: tx,
});
console.log({ result });
```

### Publish Modules

To publish a package:

```typescript
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';
import { Ed25519Keypair } from '@onelabs/sui/keypairs/ed25519';
import { Transaction } from '@onelabs/sui/transactions';

const { execSync } = require('child_process');
// Generate a new Ed25519 Keypair
const keypair = new Ed25519Keypair();
const client = new SuiClient({
	url: getFullnodeUrl('testnet'),
});
const { modules, dependencies } = JSON.parse(
	execSync(`${cliPath} move build --dump-bytecode-as-base64 --path ${packagePath}`, {
		encoding: 'utf-8',
	}),
);
const tx = new Transaction();
const [upgradeCap] = tx.publish({
	modules,
	dependencies,
});
tx.transferObjects([upgradeCap], keypair.toSuiAddress());
const result = await client.signAndExecuteTransaction({
	signer: keypair,
	transaction: tx,
});
console.log({ result });
```
