1. Prerequisites

To follow this guide, you will need to:

​
2. Install and initialize the Dub TypeScript SDK

1

Install

Install the Dub TypeScript SDK using your preferred package manager:

npm install dub
2

Initialize

Then, initialize the Dub TypeScript SDK with your API key.

lib/dub.ts
import { Dub } from "dub";

export const dub = new Dub({
  token: process.env.DUB_API_KEY, // optional, defaults to DUB_API_KEY env variable
});

You can now use the dub object to interact with the Dub API.

import { dub } from "./lib/dub";

Let’s create a short link using the Dub TypeScript SDK.

server/api/links.post.ts
export default defineEventHandler(async () => {
  try {
    const result = await dub.links.create({
      url: "https://www.google.com",
    });

    return result;
  } catch (error) {
    console.error(error);
    return error;
  }
});

Optionally, you can also pass an externalId field which is a unique identifier for the link in your own database to associate it with the link in Dub’s system.

server/api/links.post.ts
export default defineEventHandler(async () => {
  try {
    const result = await dub.links.create({
      url: "https://www.google.com",
      externalId: "12345",
    });

    return result;
  } catch (error) {
    console.error(error);
    return error;
  }
});

This will let you easily update the link or retrieve analytics for it later on using the externalId instead of the Dub linkId.

Dub TypeScript SDK provides a method to upsert a link – where an existing link is updated if it exists, or a new link is created if it doesn’t. so you don’t have to worry about checking if the link already exists.

server/api/links.put.ts
export default defineEventHandler(async () => {
  try {
    const result = await dub.links.upsert({
      url: "https://www.google.com",
    });

    return result;
  } catch (error) {
    console.error(error);
    return error;
  }
});

This way, you won’t have to worry about checking if the link already exists when you’re creating it.

Let’s update an existing link using the Dub TypeScript SDK.

You can do that in two ways:

  • Using the link’s linkId in Dub’s system.
  • Using the link’s externalId in your own database (prefixed with ext_).
server/api/links.patch.ts
export default defineEventHandler(async () => {
  try {
    // Update a link by its linkId
    const { shortLink } = await dub.links.update(
      "link_rWOKByP0bRMrstK8e4HPjprJ",
      {
        url: "https://www.google.uk", // new URL
      }
    );

    // Update a link by its externalId
    const { shortLink } = await dub.links.update("ext_12345", {
      url: "https://www.google.uk", // new URL
    });

    return { shortLink };
  } catch (error) {
    console.error(error);
    return error;
  }
});

Dub allows you to retrieve analytics for a link using the Dub TypeScript SDK.

server/api/analytics.get.ts
import { ClicksTimeseries } from "dub/models/components";

export default defineEventHandler(async () => {
  try {
    // Retrieve the timeseries analytics for the last 7 days for a link
    const response = await dub.analytics.retrieve({
      linkId: "clv3o9p9q000au1h0mc7r6l63",
      interval: "7d",
      groupBy: "timeseries",
    });

    const timeseries = response as ClicksTimeseries[];

    return timeseries;
  } catch (error) {
    console.error(error);
    return error;
  }
});

Similarly, you can retrieve analytics for a link using the externalId field.

server/api/analytics.get.ts
// Retrieve the timeseries analytics for the last 7 days for a link
const response = await dub.analytics.retrieve({
  externalId: "ext_12345",
  interval: "7d",
  groupBy: "timeseries",
});

const timeseries = response as ClicksTimeseries[];
