Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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.

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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";

const paxscanSDK = new PaxscanSDK();

async function run() {
  const result = await paxscanSDK.search.execute({
    q: "USDT",
  }, {
    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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";

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

async function run() {
  const result = await paxscanSDK.search.execute({
    q: "USDT",
  });

  console.log(result);
}

run();

Error Handling

PaxscanSDKError 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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";
import * as errors from "@paxeer-network/paxscan-sdk/models/errors";

const paxscanSDK = new PaxscanSDK();

async function run() {
  try {
    const result = await paxscanSDK.tokens.refetchInstanceMetadata({
      addressHash: "<value>",
      id: 748746,
      body: {
        recaptchaResponse: "123",
      },
    });

    console.log(result);
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof errors.PaxscanSDKError) {
      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.ForbiddenError) {
        console.log(error.data$.message); // string
      }
    }
  }
}

run();

Error Classes

Primary error:

Network errors:

Inherit from PaxscanSDKError:

  • ForbiddenError: Invalid reCAPTCHA response. Status code 403. Applicable to 1 of 56 methods.*
  • 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.

* Check the method documentation to see if the error is applicable.

Server Selection

Server Variables

The default server http://{server}/api/v2/ contains variables and is set to http://paxscan.paxeer.app/api/v2/ by default. To override default values, the following parameters are available when initializing the SDK client instance:

| Variable | Parameter | Default | Description | | -------- | ---------------- | ---------------------- | ----------- | | server | server: string | "paxscan.paxeer.app" | |

Example

import { PaxscanSDK } from "@paxeer-network/paxscan-sdk";

const paxscanSDK = new PaxscanSDK({
  serverIdx: 0,
  server: "paxscan.paxeer.app",
});

async function run() {
  const result = await paxscanSDK.search.execute({
    q: "USDT",
  });

  console.log(result);
}

run();

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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";

const paxscanSDK = new PaxscanSDK({
  serverURL: "http://paxscan.paxeer.app/api/v2/",
});

async function run() {
  const result = await paxscanSDK.search.execute({
    q: "USDT",
  });

  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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";
import { HTTPClient } from "@paxeer-network/paxscan-sdk/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 PaxscanSDK({ 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 { PaxscanSDK } from "@paxeer-network/paxscan-sdk";

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

You can also enable a default debug logger by setting an environment variable PAXSCANSDK_DEBUG to true.
