SDK Example Usage

Example

import { Daydream } from "daydream-sdk";

const daydream = new Daydream({
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  const result = await daydream.streams.create({
    pipeline: "streamdiffusion",
    params: {
      modelId: "stabilityai/sdxl-turbo",
    },
  });

  console.log(result);
}

run();

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

| Name | Type | Scheme | Environment Variable | | -------- | ---- | ----------- | -------------------- | | bearer | http | HTTP Bearer | DAYDREAM_BEARER |

To authenticate with the API the bearer parameter must be set when initializing the SDK client instance. For example:

import { Daydream } from "daydream-sdk";

const daydream = new Daydream({
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  const result = await daydream.streams.create({
    pipeline: "streamdiffusion",
    params: {
      modelId: "stabilityai/sdxl-turbo",
    },
  });

  console.log(result);
}

run();

Available Resources and Operations

Public

• create - Create a new stream
• getAll - Get all streams for user
• delete - Delete a stream
• update - Update a stream
• getById - Get stream by ID

Streams

• create - Create a new stream
• getAll - Get all streams for user
• delete - Delete a stream
• update - Update a stream
• getById - Get stream by ID

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.

• streamsCreate - Create a new stream
• streamsCreate - Create a new stream
• streamsDelete - Delete a stream
• streamsDelete - Delete a stream
• streamsGetAll - Get all streams for user
• streamsGetAll - Get all streams for user
• streamsGetById - Get stream by ID
• streamsGetById - Get stream by ID
• streamsUpdate - Update a stream
• streamsUpdate - Update a stream

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { Daydream } from "daydream-sdk";

const daydream = new Daydream({
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  const result = await daydream.streams.create({
    pipeline: "streamdiffusion",
    params: {
      modelId: "stabilityai/sdxl-turbo",
    },
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { Daydream } from "daydream-sdk";

const daydream = new Daydream({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  const result = await daydream.streams.create({
    pipeline: "streamdiffusion",
    params: {
      modelId: "stabilityai/sdxl-turbo",
    },
  });

  console.log(result);
}

run();

Error Handling

DaydreamError is the base class for all HTTP error responses. It has the following properties:

| Property | Type | Description | | ------------------- | ---------- | --------------------------------------------------------------------------------------- | | error.message | string | Error message | | error.statusCode | number | HTTP response status code eg 404 | | error.headers | Headers | HTTP response headers | | error.body | string | HTTP body. Can be empty string if no body is returned. | | error.rawResponse | Response | Raw HTTP response | | error.data$ | | Optional. Some errors may contain structured data. See Error Classes. |

Example

import { Daydream } from "daydream-sdk";
import * as errors from "daydream-sdk/models/errors";

const daydream = new Daydream({
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  try {
    const result = await daydream.streams.create({
      pipeline: "streamdiffusion",
      params: {
        modelId: "stabilityai/sdxl-turbo",
      },
    });

    console.log(result);
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof errors.DaydreamError) {
      console.log(error.message);
      console.log(error.statusCode);
      console.log(error.body);
      console.log(error.headers);

      // Depending on the method different errors may be thrown
      if (error instanceof errors.BadRequestError) {
        console.log(error.data$.success); // boolean
        console.log(error.data$.error); // string
        console.log(error.data$.code); // string
        console.log(error.data$.status); // number
        console.log(error.data$.details); // any
      }
    }
  }
}

run();

Error Classes

Primary error:

• DaydreamError: The base class for HTTP error responses.

Network errors:

* Check the method documentation to see if the error is applicable.

Server Selection

Override Server URL Per-Client

The default server can be overridden globally by passing a URL to the serverURL: string optional parameter when initializing the SDK client instance. For example:

import { Daydream } from "daydream-sdk";

const daydream = new Daydream({
  serverURL: "https://api.daydream.live",
  bearer: process.env["DAYDREAM_BEARER"] ?? "",
});

async function run() {
  const result = await daydream.streams.create({
    pipeline: "streamdiffusion",
    params: {
      modelId: "stabilityai/sdxl-turbo",
    },
  });

  console.log(result);
}

run();

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { Daydream } from "daydream-sdk";
import { HTTPClient } from "daydream-sdk/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new Daydream({ httpClient: httpClient });

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

[!WARNING] Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

import { Daydream } from "daydream-sdk";

const sdk = new Daydream({ debugLogger: console });

You can also enable a default debug logger by setting an environment variable DAYDREAM_DEBUG to true.

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
