Error Handling
Some methods specify known errors which can be thrown. All the known errors are enumerated in the models/errors/errors.ts
module. The known errors for a method are documented under the Errors tables in SDK docs. For example, the create
method may throw the following errors:
Error Type | Status Code | Content Type |
---|
errors.BadRequest | 400 | application/json |
errors.Unauthorized | 401 | application/json |
errors.Forbidden | 403 | application/json |
errors.NotFound | 404 | application/json |
errors.Conflict | 409 | application/json |
errors.InviteExpired | 410 | application/json |
errors.UnprocessableEntity | 422 | application/json |
errors.RateLimitExceeded | 429 | application/json |
errors.InternalServerError | 500 | application/json |
errors.SDKError | 4XX, 5XX | */* |
If the method throws an error and it is not captured by the known errors, it will default to throwing a SDKError
.
import { Dub } from "dub";
import {
BadRequest,
Conflict,
Forbidden,
InternalServerError,
InviteExpired,
NotFound,
RateLimitExceeded,
SDKValidationError,
Unauthorized,
UnprocessableEntity,
} from "dub/models/errors";
const dub = new Dub({
token: "DUB_API_KEY",
});
async function run() {
let result;
try {
result = await dub.links.create();
console.log(result);
} catch (err) {
switch (true) {
case (err instanceof SDKValidationError): {
console.error(err.pretty());
console.error(err.rawValue);
return;
}
case (err instanceof BadRequest): {
console.error(err);
return;
}
case (err instanceof Unauthorized): {
console.error(err);
return;
}
case (err instanceof Forbidden): {
console.error(err);
return;
}
case (err instanceof NotFound): {
console.error(err);
return;
}
case (err instanceof Conflict): {
console.error(err);
return;
}
case (err instanceof InviteExpired): {
console.error(err);
return;
}
case (err instanceof UnprocessableEntity): {
console.error(err);
return;
}
case (err instanceof RateLimitExceeded): {
console.error(err);
return;
}
case (err instanceof InternalServerError): {
console.error(err);
return;
}
default: {
throw err;
}
}
}
}
run();
Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError
that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue
. Additionally, a pretty()
method is available on this error that can be used to log a nicely formatted multi-line string since validation errors can list many issues and the plain error string may be difficult read when debugging.
In some rare cases, the SDK can fail to get a response from the server or even make the request due to unexpected circumstances such as network conditions. These types of errors are captured in the models/errors/httpclienterrors.ts
module:
HTTP Client Error | Description |
---|
RequestAbortedError | HTTP request was aborted by the client |
RequestTimeoutError | HTTP request timed out due to an AbortSignal signal |
ConnectionError | HTTP client was unable to make a request to a server |
InvalidRequestError | Any input used to create a request is invalid |
UnexpectedClientError | Unrecognised or unexpected error |
Server Selection
Override Server URL Per-Client
The default server can also 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.create();
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 { Dub } from "dub";
import { HTTPClient } from "dub/lib/http";
const httpClient = new HTTPClient({
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 Dub({ 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.create();
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 { Dub } from "dub";
const dub = new Dub({
token: "DUB_API_KEY",
});
async function run() {
const result = await dub.links.create({
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 { 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.create();
console.log(result);
}
run();
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.
To read more about standalone functions, check FUNCTIONS.md.

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 });

While we value open-source contributions to this SDK, this library is generated programmatically.
Feel free to open a PR or a Github issue as a proof of concept and we'll do our best to include it in a future release!
