Error Handling

DubError 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 { Dub } from "dub";
import * as errors from "dub/models/errors";

const dub = new Dub({
  token: "DUB_API_KEY",
});

async function run() {
  try {
    const result = await dub.links.list();

    for await (const page of result) {
      console.log(page);
    }
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof errors.DubError) {
      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.BadRequest) {
        console.log(error.data$.error); // errors.ErrorT
      }
    }
  }
}

run();

Error Classes

Primary errors:

• DubError: The base class for HTTP error responses.
  • BadRequest: The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing). Status code 400.
  • Unauthorized: Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response. Status code 401.
  • Forbidden: The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource. Unlike 401 Unauthorized, the client's identity is known to the server. Status code 403.
  • NotFound: The server cannot find the requested resource. Status code 404.
  • Conflict: This response is sent when a request conflicts with the current state of the server. Status code 409.
  • InviteExpired: This response is sent when the requested content has been permanently deleted from server, with no forwarding address. Status code 410.
  • UnprocessableEntity: The request was well-formed but was unable to be followed due to semantic errors. Status code 422.
  • RateLimitExceeded: The user has sent too many requests in a given amount of time ("rate limiting"). Status code 429.
  • InternalServerError: The server has encountered a situation it does not know how to handle. Status code 500.

Less common errors (6)

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 DubError:

• 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 { Dub } from "dub";

const dub = new Dub({
  serverURL: "https://api.dub.co",
  token: "DUB_API_KEY",
});

async function run() {
  const result = await dub.links.list();

  for await (const page of result) {
    console.log(page);
  }
}

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 { Dub } from "dub";
import { ProxyAgent } from "undici";
import { HTTPClient } from "dub/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 Dub({ httpClient: httpClient });

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
token	http	HTTP Bearer

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

import { Dub } from "dub";

const dub = new Dub({
  token: "DUB_API_KEY",
});

async function run() {
  const result = await dub.links.list();

  for await (const page of result) {
    console.log(page);
  }
}

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 { Dub } from "dub";

const dub = new Dub({
  token: "DUB_API_KEY",
});

async function run() {
  const result = await dub.links.list(undefined, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  for await (const page of result) {
    console.log(page);
  }
}

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 { Dub } from "dub";

const dub = new Dub({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  token: "DUB_API_KEY",
});

async function run() {
  const result = await dub.links.list();

  for await (const page of result) {
    console.log(page);
  }
}

run();

Pagination

Some of the endpoints in this SDK support pagination. To use pagination, you make your SDK calls as usual, but the returned response object will also be an async iterable that can be consumed using the for await...of syntax.

Here's an example of one such pagination call:

import { Dub } from "dub";

const dub = new Dub({
  token: "DUB_API_KEY",
});

async function run() {
  const result = await dub.links.list();

  for await (const page of result) {
    console.log(page);
  }
}

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.

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 { Dub } from "dub";

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