It has been a while since we have developed the first version of the developer api where we have supported creating and editing Upstash redis databases and Upstash teams. Since then we have brought many great features to Upstash including a whole new product, the Serverless Kafka!

User feedback is important to guide product decisions. We built a widget to help you get feedback from your users. It is a React component which calls Next.js API as its backend. The backend API simply sends the feedback data to Upstash Redis database. Also, you will be able to see and manage the submitted data in Upstash Console Integrations Page

When you add the component to your Next.js page, an icon will be displayed on bottom right corner. When clicked, feedback form will be visible. Check the demo to see how it works.

Next.js enables developers to build full stack applications with the Server Side Rendering capability. Vercel and Netlify help them to write the backend API with serverless functions. So the next question is what is the ideal database for Next.js apps. In this post, I will review the databases which are popular among the Next.js community. I will comment on how they fit the serverless model. Two things to check:

  • Serverless pricing: Is the price pay-per-use? When the database is not in use, do you still have to pay?
  • Serverless connections: Is there support for HTTP based connections? So there should not be any connection problems which are common with serverless functions.

In this post, we will show how to push Stripe events to Apache Kafka using Upstash Webhook API. Once data is in Kafka there are many use cases how you can use it:

  • Processing payment events (with Apache Flink or Spark) to notify your business and sales team.
  • Trigger processes such as sending Slack messages or email if a payment fails.
  • Using a Kafka connector to move the data to a database or data warehouse to feed reporting and analytics applications.
  • Feeding new payment activity data to your CRM.

In a mobile application, there may be a need to send some information, warnings or guidance to the end-users in the app. One way to do this is sending in-app announcements to the users.

In this blog post, we will develop a mobile application to show how to send announcements to the users with serverless Redis. We will use React Native to develop a mobile application and Upstash for a serverless Redis, which is directly connected to the app.

Next.js is one of the most popular frontend frameworks with React at its core. It can generate static HTML or render dynamically on the client and server. This makes it a versatile tool for applications and websites of every type. And the best thing is, it’s open-source, and you can use it free of charge!

NextAuth is a third-party library for Next.js that helps you integrate different identity providers and databases. You can save your users time at sign up and still have all their essential account information in your chosen database. NextAuth comes with support for over 50 authentication providers, including GitHub, Google, Facebook, Coinbase, and many more.

Nowadays, it is hard to image the IT world without Redis databases. In Stackoverflow's Developer Survey published in 2021, the in-memory database enjoyed great popularity and was chosen as the most loved database by over 70000 developers. As an in-memory database, Redis delivers strong performance, making it ideal in scenarios that require short response times and minimal latency. However, the use cases of Redis are often wrongly understood as being limited to caching and message-brokering. Today we'll look at why this is wrong and use Redis in the role of a primary database.

In this post, we will showcase how to send Github events to Kafka. We will use Vercel functions as a webhook to send events to Upstash Kafka.

You can send all types of repository events to Kafka. We will use Kafka as a persistent hub for our data thanks to its replication and durability capability. Storing Github events in Kafka opens possibilities for both streaming and batching use cases. You can replicate the events to a database for analytical purposes. At the same time, you can run real time processes to trigger alerts for your security team.

As full stack web framework Remix provides APIs to deal with common web server use cases. This post will focus on sessions and why and how you can use Upstash to store them.

What is a session?

The Remix docs have a very good introduction to sessions

In a few words - sessions are a mechanism that allows the server and the client to share user data / state. Example of session uses are tracking user authentication state, shopping carts status, flash messages etc.

Remix is a new take on what it means to be a fullstack React framework, focusing on existing web standards and tying the frontend closely to the backend. This tight coupling is a breath of fresh air when you see how simple it is to load data into your React components or how to process data submitted from a form.

In this article we will see Remix's power by creating a simple Feature Flag management system using Upstash Redis as the database.
