## Features
- **Fully tree-shakeable**: import and bundle only the modules you need
- **Framework agnostic**: integrate with any web framework (React, Vue, Svelte, Solid, etc.)
- **Lightweight and minimal**: 153 KB gzipped to connect a React app to Keplr via browser extension or WalletConnect, 10x smaller than Cosmos Kit V2 (see [benchmarks](#benchmarks))
- **Uses modern web APIs**: no dependencies on Node.js and minimal dependencies on third-party libraries where possible
- **Supports modern bundlers**: works with Vite, SWC, Rollup, etc.
- **Fully typed**: written in TypeScript and ships with type definitions
## Installing
For Cosmos SDK v0.47 and below:
```sh
npm install @sonr.io/es
pnpm add @sonr.io/es
yarn add @sonr.io/es
```
For Cosmos SDK v0.50, install using the `sdk50` tag:
```sh
npm install @sonr.io/es@sdk50
pnpm add @sonr.io/es@sdk50
yarn add @sonr.io/es@sdk50
```
> [!IMPORTANT]
> The bump from v0.47 to v0.50 introduces significant breaking changes and is not recommended to be used unless necessary. To reduce the impact on consumers, the `main` branch and the published package on npm with the `latest` tag will continue to target v0.47 until the majority of live chains have migrated to v0.50.
>
> The [`parallel/sdk50`](https://github.com/coinhall/@sonr.io/es/tree/parallel/sdk50) branch targetting v0.50 will be developed and maintained in parallel with the `main` branch, where the same patch version number should have feature parity (eg. `@sonr.io/es@0.0.69` should have the same features as `@sonr.io/es@0.0.69-sdk50.0`).
### Using with TypeScript
This library only exports ES modules. To ensure imports from this library work correctly, the following configuration is required in `tsconfig.json`:
```ts
{
"compilerOptions": {
"moduleResolution": "bundler", // recommended if using modern bundlers
// or "node16"
// or "nodenext"
// but NOT "node"
}
}
```
### Using with Vite
If you are using Vite, the following configuration is required in `vite.config.ts`:
```ts
export default defineConfig({
define: {
global: "window",
},
});
```
> This can be removed once support for WalletConnect v1 is no longer required.
### Using Station wallet
The Station wallet currently relies on WalletConnect v1. If you want to import and use `StationController`, a polyfill for `Buffer` is required:
```ts
// First, install the buffer package
npm install buffer
// Then, create a new file 'polyfill.ts'
import { Buffer } from "buffer";
(window as any).Buffer = Buffer;
// Finally, import the above file in your entry file
import "./polyfill";
```
See [`examples/solid-vite`](./examples/solid-vite) for a working example.
> This can be removed once support for WalletConnect v1 is no longer required.
## Examples
### Using the ESM Autoloader (Browser/CDN)
The library includes an autoloader that automatically initializes all modules and makes them available globally via `window.Sonr`. This is perfect for quick prototyping or when you want to use the library without a build system.
#### Method 1: Load from CDN
```html
Sonr ES Example
```
#### Method 2: Import as ES Module
```html
```
#### Method 3: Using in Node.js/Build Systems
```javascript
// Import specific modules (tree-shakeable)
import { registerWithPasskey, loginWithPasskey } from '@sonr.io/es/client/auth';
import { createMotorPlugin } from '@sonr.io/es/plugins';
import { bech32 } from '@sonr.io/es/codec';
// Or import the entire autoloader
import Sonr from '@sonr.io/es/autoloader';
// Initialize and use
async function main() {
// Initialize Sonr
await Sonr.init({
enableMotor: true,
enableVault: false
});
// Use WebAuthn
if (await Sonr.webauthn.isAvailable()) {
const result = await Sonr.webauthn.register({
username: 'bob',
displayName: 'Bob Smith',
rpId: 'example.com',
rpName: 'Example App'
});
console.log('Registered:', result);
}
// Access plugins
const motor = await Sonr.createMotorPlugin();
console.log('Motor plugin ready:', motor);
// Use codec utilities
const address = Sonr.codec.bech32.encode('sonr', [1, 2, 3, 4]);
console.log('Encoded address:', address);
}
main();
```
#### Autoloader API Reference
The autoloader exposes the following on `window.Sonr`:
```javascript
window.Sonr = {
// Core modules
auth: {...}, // Authentication utilities
client: {...}, // Blockchain client
codec: {...}, // Encoding/decoding utilities
wallet: {...}, // Wallet management
registry: {...}, // Chain registry
plugins: {...}, // WASM plugins (motor, vault)
// WebAuthn shortcuts
webauthn: {
register: registerWithPasskey,
login: loginWithPasskey,
isSupported: isWebAuthnSupported,
isAvailable: isWebAuthnAvailable,
isConditionalAvailable: isConditionalMediationAvailable,
bufferToBase64url: bufferToBase64url,
base64urlToBuffer: base64urlToBuffer
},
// Plugin shortcuts
motor: {...}, // Motor plugin namespace
vault: {...}, // Vault plugin namespace
// Factory functions
createMotorPlugin: Function,
createVaultClient: Function,
// Utilities
init: async (config) => {...}, // Initialize with config
getEnvironment: () => {...}, // Get environment info
isBrowser: Boolean, // Check if running in browser
isNode: Boolean, // Check if running in Node.js
version: String // Library version
}
```
#### Events
The autoloader dispatches the following events:
- `sonr:ready` - Fired when the library is fully loaded and initialized
```javascript
window.addEventListener('sonr:ready', (event) => {
const Sonr = event.detail;
console.log('Sonr is ready!', Sonr);
});
```

## Modules
This package is split into multiple subdirectories, with each subdirectory having their own set of functionalities. The root directory does not contain any exports, and all exports are exported from the subdirectories. Thus, imports must be done by referencing the subdirectories (ie. `import { ... } from "@sonr.io/es/client"`).
### `@sonr.io/es/client`
This directory contains models and helper functions to interact with Cosmos SDK via the [CometBFT RPC](https://docs.cosmos.network/v0.50/core/grpc_rest#cometbft-rpc).
### `@sonr.io/es/codec`
This directory contains various encoding and decoding functions that relies solely on [Web APIs](https://developer.mozilla.org/en-US/docs/Web/API) and has no dependencies on Node.js. For modern browsers and Node v16+, this should work out of the box.
### `@sonr.io/es/protobufs`
This directory contains the auto-generated code for various Cosmos SDK based protobufs. See `scripts/gen-protobufs.mjs` for the script that generates the code.
### `@sonr.io/es/registry`
This directory contains various APIs, data, and types needed for wallet interactions (ie. Keplr). Some types are auto-generated, see `scripts/gen-registry.mjs` for the script that generates the types.
### `@sonr.io/es/wallet`
This directory is a [Cosmos Kit](https://cosmoskit.com) alternative to interact with wallets across all Cosmos SDK based blockchains. See [`examples/solid-vite`](./examples/solid-vite) for a working example.
**Wallets supported**:
- [Station](https://docs.terra.money/learn/station/)
- [Keplr](https://www.keplr.app/)
- [Leap](https://www.leapwallet.io/)
- [Cosmostation](https://wallet.cosmostation.io/)
- [OWallet](https://owallet.dev/)
- [Compass](https://compasswallet.io/) (for Sei only)
- [MetaMask](https://metamask.io/) (for Injective only)
- [Ninji](https://ninji.xyz/) (for Injective only)
**Features**:
- Supports both browser extension (desktop) and WalletConnect (mobile)
- Unified interface for connecting, signing, broadcasting, and event handling
- Signing of arbitrary messages (for wallets that support it)
- Simultaneous connections to multiple WalletConnect wallets
## Benchmarks
See the [`benchmarks`](./benchmarks) folder, where the bundle size of SonrES is compared against Cosmos Kit. The following are adhered to:
- Apps should only contain the minimal functionality of connecting to Osmosis via Keplr using both the browser extension and WalletConnect wallets
- Apps should be built using React 18 (as Cosmos Kit has a [hard dependency](https://docs.cosmoskit.com/get-started)) and Vite
- Use the total sum of all generated bundles as reported by Vite after running the `vite build` command, including the size of all other dependencies like React/HTML/CSS/etc. (note: this is crude and not 100% accurate, but is the simplest method)

// Store enclave data
const enclaveData = {
publicKey: 'ed25519:...',
privateKeyShares: ['share1', 'share2', 'share3'],
threshold: 2,
parties: 3,
};
const { cid } = await client.addEnclaveData(
new TextEncoder().encode(JSON.stringify(enclaveData))
);
// Retrieve data
const retrieved = await client.getEnclaveData(cid);
const data = JSON.parse(new TextDecoder().decode(retrieved));

],
apiEndpoints: {
local: 'http://localhost:5001',
testnet: 'https://ipfs.testnet.sonr.io',
mainnet: 'https://ipfs.sonr.io'
}
}
```
#### Environment Variables
The IPFS client automatically detects and uses these environment variables:
- `IPFS_GATEWAY_URL` - Primary gateway URL
- `IPFS_API_URL` - API endpoint URL
- `SONR_ENV` - Environment ('local', 'testnet', 'mainnet')
```bash
# Example .env file
IPFS_GATEWAY_URL=https://my-custom-gateway.com
IPFS_API_URL=https://my-ipfs-api.com:5001
SONR_ENV=testnet
```
#### EnclaveStorageConfig
```typescript
interface EnclaveStorageConfig {
encryptionRequired: boolean // Require encryption for all data
pinningEnabled: boolean // Auto-pin stored data
redundancy: number // Number of redundant copies
maxRetries: number // Max retry attempts
operationTimeout?: number // Operation timeout in ms
}
```
### Usage Examples
#### Basic Configuration
```typescript
import { createIPFSClient, DEFAULT_IPFS_CONFIG } from '@sonr.io/es/ipfs'
// Use defaults
const client = await createIPFSClient()
// Custom configuration
const customClient = await createIPFSClient({
gatewayUrl: 'https://my.gateway.com',
apiUrl: 'https://my.api.com:5001',
environment: 'testnet',
timeout: 60000,
maxRetries: 5
})
// Update configuration dynamically
client.updateConfig({
gatewayUrl: 'https://new.gateway.com',
timeout: 30000
})
// Get current configuration
const config = client.getConfig()
console.log('Using gateway:', config.gatewayUrl)
```
#### Using the API Methods
```typescript
// Add content via HTTP API (requires apiUrl configuration)
const data = new Uint8Array([1, 2, 3, 4])
const cid = await client.addViaAPI(data)
console.log('Added via API:', cid)
// Pin content to prevent garbage collection
await client.pinViaAPI(cid)
// Get IPFS node information
const nodeInfo = await client.getNodeInfoViaAPI()
console.log('Node ID:', nodeInfo.ID)
console.log('Agent:', nodeInfo.AgentVersion)
```
See the [examples directory](./examples/ipfs-enclave-usage.ts) for comprehensive usage examples including:
- Basic IPFS operations
- MPC enclave storage
- Vault integration
- Caching strategies
- Error handling
- Performance optimization
### Performance Best Practices
1. **Use Caching Aggressively**: Enable the cache layer for frequently accessed data
2. **Batch Operations**: Use batch methods when storing/retrieving multiple items
3. **Preload Critical Data**: Use cache preloading for known CIDs
4. **Configure Gateways**: Provide multiple gateway URLs for redundancy
5. **Set Appropriate Timeouts**: Configure timeouts based on your network conditions
6. **Monitor Cache Stats**: Use cache statistics to optimize hit rates
### Troubleshooting
#### Common Issues
**Connection Failed**
```typescript
// Provide fallback gateways
const client = await createIPFSClient({
gateways: [
'http://localhost:5001', // Local node
'https://gateway.pinata.cloud', // Public gateway
'https://ipfs.io' // Fallback
]
});
```
**Slow Retrieval**
```typescript
// Enable caching for better performance
const cache = createIPFSCache({
maxSize: 200,
ttl: 300000, // 5 minutes
enablePersistence: true
});
// Preload frequently used CIDs
await cache.preload(cids, fetchFunction);
```
**Network Timeouts**
```typescript
// Configure retry logic
const manager = new EnclaveIPFSManager(client, {
maxRetries: 5,
operationTimeout: 30000 // 30 seconds
});
```
### Security Considerations
1. **Always Encrypt Sensitive Data**: Use consensus-based encryption for enclave data
2. **Verify CID Integrity**: Always verify retrieved data matches expected CID
3. **Use HTTPS Gateways**: Prefer HTTPS gateways over HTTP
4. **Validate Enclave Structure**: Validate threshold and parties before storage
5. **Implement Access Control**: Use UCAN tokens for authorization
### Testing
Run unit tests:
```bash
pnpm test
```
Run integration tests (requires Docker):
```bash
docker-compose up -d ipfs
pnpm test:integration
```
