• pause - Pauses the continuous execution of specified sync(s) for a given connection or all applicable connections if no connection is specified.
• status - Get the status of specified sync(s) for a given connection or all applicable connections if no connection is specified.
• updateConnectionFrequency - Override a sync's default frequency for a specific connection or revert to the default frequency.

action

• createTrigger - Triggers an action for a connection.

proxy

• get - Make a GET request with the Proxy.

• update - Make a PUT request with the Proxy.
• patch - Make a PATCH request with the Proxy.

Error Handling

All SDK methods return a response object or throw an error. If Error objects are specified in your OpenAPI Spec, the SDK will throw the appropriate Error type.

| Error Object | Status Code | Content Type | | ------------------ | ------------------ | ------------------ | | errors.Response400 | 400 | application/json | | errors.SDKError | 4xx-5xx | / |

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.

import { Nango } from "@simplesagar92/nango";
import * as errors from "@simplesagar92/nango/models/errors";

const nango = new Nango();

async function run() {
    let result;
    try {
        result = await nango.integrations.create({});
    } catch (err) {
        switch (true) {
            case err instanceof errors.SDKValidationError: {
                // Validation errors can be pretty-printed
                console.error(err.pretty());
                // Raw value may also be inspected
                console.error(err.rawValue);
                return;
            }
            case err instanceof errors.Response400: {
                console.error(err); // handle exception
                return;
            }
            default: {
                throw err;
            }
        }
    }

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

run();

Server Selection

Select Server by Name

You can override the default server globally by passing a server name to the server 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 names associated with the available servers:

| Name | Server | Variables | | ----- | ------ | --------- | | prod | https://api.nango.dev | None | | local | http://localhost:3003 | None |

import { Nango } from "@simplesagar92/nango";

const nango = new Nango({
    server: "local",
});

async function run() {
    const result = await nango.getEnvironmentVariables();

    // 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 optional parameter when initializing the SDK client instance. For example:

import { Nango } from "@simplesagar92/nango";

const nango = new Nango({
    serverURL: "https://api.nango.dev",
});

async function run() {
    const result = await nango.getEnvironmentVariables();

    // 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 { Nango } from "@simplesagar92/nango";
import { HTTPClient } from "@simplesagar92/nango/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 Nango({ httpClient });

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!
