description: Type-safe JS client for opencode server.
|
||
---
|
||
|
||
import config from "../../../config.mjs"
|
||
export const typesUrl = `${config.github}/blob/dev/packages/sdk/js/src/gen/types.gen.ts`
|
||
|
||
The opencode JS/TS SDK provides a type-safe client for interacting with the server.
|
||
Use it to build integrations and control opencode programmatically.
|
||
|
||
[Learn more](/docs/server) about how the server works. For examples, check out the [projects](/docs/ecosystem#projects) built by the community.
|
||
|
||
---
|
||
|
||
## Install
|
||
|
||
Install the SDK from npm:
|
||
|
||
```bash
|
||
npm install @opencode-ai/sdk
|
||
```
|
||
|
||
---
|
||
|
||
## Create client
|
||
|
||
Create an instance of opencode:
|
||
|
||
```javascript
|
||
import { createOpencode } from "@opencode-ai/sdk"
|
||
|
||
const { client } = await createOpencode()
|
||
```
|
||
|
||
This starts both a server and a client
|
||
|
||
#### Options
|
||
|
||
| Option | Type | Description | Default |
|
||
| ---------- | ------------- | ------------------------------ | ----------- |
|
||
| `hostname` | `string` | Server hostname | `127.0.0.1` |
|
||
| `port` | `number` | Server port | `4096` |
|
||
| `signal` | `AbortSignal` | Abort signal for cancellation | `undefined` |
|
||
| `timeout` | `number` | Timeout in ms for server start | `5000` |
|
||
| `config` | `Config` | Configuration object | `{}` |
|
||
|
||
---
|
||
|
||
## Config
|
||
|
||
You can pass a configuration object to customize behavior. The instance still picks up your `opencode.json`, but you can override or add configuration inline:
|
||
|
||
```javascript
|
||
import { createOpencode } from "@opencode-ai/sdk"
|
||
|
||
const opencode = await createOpencode({
|
||
hostname: "127.0.0.1",
|
||
port: 4096,
|
||
config: {
|
||
model: "anthropic/claude-3-5-sonnet-20241022",
|
||
},
|
||
})
|
||
|
||
console.log(`Server running at ${opencode.server.url}`)
|
||
|
||
opencode.server.close()
|
||
```
|
||
|
||
## Client only
|
||
|
||
If you already have a running instance of opencode, you can create a client instance to connect to it:
|
||
|
||
```javascript
|
||
import { createOpencodeClient } from "@opencode-ai/sdk"
|
||
|
||
const client = createOpencodeClient({
|
||
baseUrl: "http://localhost:4096",
|
||
})
|
||
```
|
||
|
||
#### Options
|
||
|
||
| Option | Type | Description | Default |
|
||
| --------------- | ---------- | -------------------------------- | ----------------------- |
|
||
| `baseUrl` | `string` | URL of the server | `http://localhost:4096` |
|
||
| `fetch` | `function` | Custom fetch implementation | `globalThis.fetch` |
|
||
| `parseAs` | `string` | Response parsing method | `auto` |
|
||
| `responseStyle` | `string` | Return style: `data` or `fields` | `fields` |
|
||
| `throwOnError` | `boolean` | Throw errors instead of return | `false` |
|
||
|
||
---
|
||
|
||
## Types
|
||
|
||
The SDK includes TypeScript definitions for all API types. Import them directly:
|
||
|
||
```typescript
|
||
import type { Session, Message, Part } from "@opencode-ai/sdk"
|
||
```
|
||
|
||
All types are generated from the server's OpenAPI specification and available in the <a href={typesUrl}>types file</a>.
|
||
|
||
---
|
||
|
||
## Errors
|
||
|
||
The SDK can throw errors that you can catch and handle:
|
||
|
||
```typescript
|
||
try {
|
||
await client.session.get({ path: { id: "invalid-id" } })
|
||
} catch (error) {
|
||
console.error("Failed to get session:", (error as Error).message)
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## APIs
|
||
|
||
The SDK exposes all server APIs through a type-safe client.
