| 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 the SDK from npm: |
|
|
| ```bash |
| npm install @opencode-ai/sdk |
| ``` |
|
|
| --- |
| |
| |
|
|
| Create an instance of opencode: |
|
|
| ```javascript |
| import { createOpencode } from "@opencode-ai/sdk" |
|
|
| const { client } = await createOpencode() |
| ``` |
|
|
| This starts both a server and a client |
|
|
| |
|
|
| | 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 | `{}` | |
|
|
| --- |
| |
| |
|
|
| 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() |
| ``` |
|
|
| |
|
|
| 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", |
| }) |
| ``` |
|
|
| |
|
|
| | 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` | |
|
|
| --- |
| |
| |
|
|
| 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>. |
|
|
| --- |
| |
| |
|
|
| 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) |
| } |
| ``` |
|
|
| --- |
| |
| |
|
|
| You can request structured JSON output from the model by specifying an `format` with a JSON schema. The model will use a `StructuredOutput` tool to return validated JSON matching your schema. |
|
|
| |
|
|
| ```typescript |
| const result = await client.session.prompt({ |
| path: { id: sessionId }, |
| body: { |
| parts: [{ type: "text", text: "Research Anthropic and provide company info" }], |
| format: { |
| type: "json_schema", |
| schema: { |
| type: "object", |
| properties: { |
| company: { type: "string", description: "Company name" }, |
| founded: { type: "number", description: "Year founded" }, |
| products: { |
| type: "array", |
| items: { type: "string" }, |
| description: "Main products", |
| }, |
| }, |
| required: ["company", "founded"], |
| }, |
| }, |
| }, |
| }) |
|
|
| // Access the structured output |
| console.log(result.data.info.structured_output) |
| // { company: "Anthropic", founded: 2021, products: ["Claude", "Claude API"] } |
| ``` |
|
|
| |
|
|
| | Type | Description | |
| | ------------- | ------------------------------------------------------ | |
| | `text` | Default. Standard text response (no structured output) | |
| | `json_schema` | Returns validated JSON matching the provided schema | |
|
|
| |
|
|
| When using `type: 'json_schema'`, provide: |
|
|
| | Field | Type | Description | |
| | ------------ | --------------- | ---------------------------------------------------------- | |
| | `type` | `'json_schema'` | Required. Specifies JSON schema mode | |
| | `schema` | `object` | Required. JSON Schema object defining the output structure | |
| | `retryCount` | `number` | Optional. Number of validation retries (default: 2) | |
|
|
| |
|
|
| If the model fails to produce valid structured output after all retries, the response will include a `StructuredOutputError`: |
|
|
| ```typescript |
| if (result.data.info.error?.name === "StructuredOutputError") { |
| console.error("Failed to produce structured output:", result.data.info.error.message) |
| console.error("Attempts:", result.data.info.error.retries) |
| } |
| ``` |
|
|
| |
|
|
| 1. **Provide clear descriptions** in your schema properties to help the model understand what data to extract |
| 2. **Use `required`** to specify which fields must be present |
| 3. **Keep schemas focused** - complex nested schemas may be harder for the model to fill correctly |
| 4. **Set appropriate `retryCount`** - increase for complex schemas, decrease for simple ones |
