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 { Novu } from "@novu/api";

const novu = new Novu({
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.subscribers.list();

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

run();

Error Handling

All SDK methods return a response object or throw an error. By default, an API error will throw a errors.SDKError.

If a HTTP request fails, an operation my also throw an error from 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

In addition, when custom error responses are specified for an operation, the SDK may throw their associated Error type. You can refer to respective Errors tables in SDK docs for more details on possible error types for each operation. For example, the trigger method may throw the following errors:

Error Type	Status Code	Content Type
errors.SDKError	4XX, 5XX	*/*

import { Novu } from "@novu/api";
import { SDKValidationError } from "@novu/api/models/errors";

const novu = new Novu({
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  let result;
  try {
    result = await novu.trigger({
      name: "workflow_identifier",
      to: [
        {
          topicKey: "<value>",
          type: "Topic",
        },
        {
          topicKey: "<value>",
          type: "Topic",
        },
      ],
    });

    // Handle the result
    console.log(result);
  } catch (err) {
    switch (true) {
      case (err instanceof SDKValidationError): {
        // Validation errors can be pretty-printed
        console.error(err.pretty());
        // Raw value may also be inspected
        console.error(err.rawValue);
        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 string since validation errors can list many issues and the plain error string may be difficult read when debugging.

Server Selection

Select Server by Index

You can override the default server globally by passing a server index to the serverIdx: number optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

#	Server
0	https://api.novu.co
1	https://eu.api.novu.co

Example

import { Novu } from "@novu/api";

const novu = new Novu({
  serverIdx: 1,
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.trigger({
    name: "workflow_identifier",
    to: [
      {
        topicKey: "<value>",
        type: "Topic",
      },
      {
        topicKey: "<value>",
        type: "Topic",
      },
    ],
  });

  // Handle the result
  console.log(result);
}

run();

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 { Novu } from "@novu/api";

const novu = new Novu({
  serverURL: "https://api.novu.co",
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.trigger({
    name: "workflow_identifier",
    to: [
      {
        topicKey: "<value>",
        type: "Topic",
      },
      {
        topicKey: "<value>",
        type: "Topic",
      },
    ],
  });

  // Handle the result
  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 { Novu } from "@novu/api";
import { HTTPClient } from "@novu/api/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 Novu({ httpClient });

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
apiKey	apiKey	API key

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

import { Novu } from "@novu/api";

const novu = new Novu({
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.trigger({
    name: "workflow_identifier",
    to: [
      {
        topicKey: "<value>",
        type: "Topic",
      },
      {
        topicKey: "<value>",
        type: "Topic",
      },
    ],
  });

  // Handle the result
  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 { Novu } from "@novu/api";

const novu = new Novu({
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.trigger({
    name: "workflow_identifier",
    to: [
      {
        topicKey: "<value>",
        type: "Topic",
      },
      {
        topicKey: "<value>",
        type: "Topic",
      },
    ],
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  // Handle the result
  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 { Novu } from "@novu/api";

const novu = new Novu({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  apiKey: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await novu.trigger({
    name: "workflow_identifier",
    to: [
      {
        topicKey: "<value>",
        type: "Topic",
      },
      {
        topicKey: "<value>",
        type: "Topic",
      },
    ],
  });

  // Handle the result
  console.log(result);
}

run();

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 { Novu } from "@novu/api";

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

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. 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!
