SDK Example Usage

Example

import { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.credentials.listCredentials({});

  console.log(result);
}

run();

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

| Name | Type | Scheme | Environment Variable | | ------------ | ---- | ----------- | ------------------------- | | apiKeyAuth | http | HTTP Bearer | CONTINUOUS_API_KEY_AUTH |

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

import { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.credentials.listCredentials({});

  console.log(result);
}

run();

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.

File uploads

Certain SDK methods accept files as part of a multi-part request. It is possible and typically recommended to upload files as a stream rather than reading the entire contents into memory. This avoids excessive memory consumption and potentially crashing with out-of-memory errors when working with very large files. The following example demonstrates how to attach a file stream to a request.

[!TIP]

Depending on your JavaScript runtime, there are convenient utilities that return a handle to a file without reading the entire contents into memory:

• Node.js v20+: Since v20, Node.js comes with a native openAsBlob function in node:fs.
• Bun: The native Bun.file function produces a file handle that can be used for streaming file uploads.
• Browsers: All supported browsers return an instance to a File when reading the value from an <input type="file"> element.
• Node.js v18: A file stream can be created using the fileFrom helper from fetch-blob/from.js.

import { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.simulators.buildSimulator({
    request: {
      filter: [],
      instructions: "Return stable example data for every operation.",
      model: "claude-fable-5-1",
      name: "billing-api",
      specKind: "openapi",
    },
  });

  console.log(result);
}

run();

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 { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.credentials.listCredentials({}, {
    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 { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.credentials.listCredentials({});

  console.log(result);
}

run();

Error Handling

ContinuousError 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 { Continuous } from "@continuous-labs/sdk";
import * as errors from "@continuous-labs/sdk/models/errors";

const continuous = new Continuous({
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  try {
    const result = await continuous.credentials.listCredentials({});

    console.log(result);
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof errors.ContinuousError) {
      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.ErrorT) {
        console.log(error.data$.code); // string
        console.log(error.data$.detail); // string
        console.log(error.data$.validation); // models.SpecificationValidation
      }
    }
  }
}

run();

Error Classes

Primary errors:

• ContinuousError: The base class for HTTP error responses.
  • ErrorT: Generic error.

Network errors:

• ConnectionError: HTTP client was unable to make a request to a server.
• RequestTimeoutError: HTTP request timed out due to an AbortSignal signal.
• RequestAbortedError: HTTP request was aborted by the client.
• InvalidRequestError: Any input used to create a request is invalid.
• UnexpectedClientError: Unrecognised or unexpected error.

Inherit from ContinuousError:

• ResponseValidationError: Type mismatch between the data returned from the server and the structure expected by the SDK. See error.rawValue for the raw value and error.pretty() for a nicely formatted multi-line string.

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 { Continuous } from "@continuous-labs/sdk";

const continuous = new Continuous({
  serverURL: "https://api.continuouslabs.ai",
  apiKeyAuth: process.env["CONTINUOUS_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await continuous.credentials.listCredentials({});

  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:

• route requests through a proxy server using undici's ProxyAgent
• use the "beforeRequest" hook to add a custom header and a timeout to requests
• use the "requestError" hook to log errors

import { Continuous } from "@continuous-labs/sdk";
import { ProxyAgent } from "undici";
import { HTTPClient } from "@continuous-labs/sdk/lib/http";

const dispatcher = new ProxyAgent("http://proxy.example.com:8080");

const httpClient = new HTTPClient({
  // 'fetcher' takes a function that has the same signature as native 'fetch'.
  fetcher: (input, init) =>
    // 'dispatcher' is specific to undici and not part of the standard Fetch API.
    fetch(input, { ...init, dispatcher } as RequestInit),
});

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 Continuous({ 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 { Continuous } from "@continuous-labs/sdk";

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

You can also enable a default debug logger by setting an environment variable CONTINUOUS_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.
