The blog post provides a comprehensive guide to building a custom in-app feed using the Knock JavaScript client, inspired by the design of Notion's in-app feed. It details the process using Next.js and shadcn/ui to create a user interface where users can mark items as read, archive them, and switch between different feed views. It further explains setting up the Knock client, configuring in-app channels, and workflows to fetch and manage user feed data. The tutorial includes practical steps for cloning a GitHub repository, installing dependencies, and configuring Knock with API keys and user IDs. Through the implementation of features such as real-time updates, message engagement status management, and conditional rendering of feed items, the post demonstrates the flexibility and customization options available with Knock's tools, while also highlighting design elements that enhance user experience, such as opacity adjustments for read items and the inclusion of a "New" icon for unread items.

The post provides a detailed guide on building a custom in-app feed modeled after Notion's interface using the Knock JavaScript client, Next.js, and shadcn/ui. It walks through configuring an in-app channel and workflow in Knock, fetching and updating a user's feed through the Feed API, and managing message engagement statuses like read and archived. The project emphasizes creating a tabbed feed interface, allowing users to switch views and interact with feed items, with functionalities such as marking all items as read or archived. The guide also highlights aesthetic elements from Notion's feed, such as opacity treatments for read items and a "New" icon for unread items, enhancing user experience. The example project is available on Knock's GitHub, and the post encourages developers to explore the flexibility of Knock's tools by signing up for free.

Knock has launched version 1.0 of its mobile client SDKs, designed to simplify the integration of rich push and in-app notifications into mobile applications. These SDKs, available for iOS, Android, Flutter, and React Native, encapsulate Knock's client APIs and provide streamlined methods for managing push notifications, including device token registration, authentication, and engagement tracking. They facilitate the easy incorporation of in-app notification feeds and inboxes, with future updates promising pre-built UI elements. Additionally, Knock extends its notification services to other channels such as email, SMS, and Slack, offering a comprehensive platform for managing notification templates, workflows, and user preferences. The SDKs are available to all Knock customers, who can begin integrating them by accessing detailed documentation and a free account offering 10,000 notifications monthly.

This text provides a comprehensive guide on building a real-time activity feed for a B2B SaaS application using Node.js and Socket.io, specifically focusing on displaying GitHub repository updates. By harnessing WebSockets and webhooks, it outlines the creation of a Node.js server that listens for GitHub webhook events and updates connected clients in real-time, alongside serving a static HTML client interface. The process involves setting up server endpoints to receive webhook payloads, handling WebSocket connections, and developing a front-end using Socket.io to dynamically update content as new commit data is received. The text highlights the need for additional considerations for a production-level feed, such as component variants, data persistence, and scalability, and suggests using services like Knock for implementing in-app notifications with pre-built components to simplify the process.

Push notifications play a pivotal role in enhancing user engagement and retention in mobile apps by facilitating direct communication between apps and users via the operating system's push notification service, such as Apple Push Notification Service (APNS) for iOS and Firebase Cloud Messaging (FCM) for Android. To initiate push notifications, apps must obtain user consent, which involves generating a unique device token that is used to register the device with the app server. This token allows the server to send notifications to the device through the respective push notification service. The services handle the routing and delivery of notifications, considering device availability and network conditions, while developers manage the creation and management of notification payloads and device tokens on their servers. Ensuring that payloads conform to size limits and securing device tokens are critical for maintaining effective notification systems. Services like Knock further simplify this process by managing connections and allowing for unified messaging across multiple platforms without the need for developers to handle different payload structures or maintain stateful connections with push notification services.

Activity feeds serve as a real-time stream of updates in applications, significantly enhancing user engagement by providing critical information and facilitating collaboration, especially in complex B2B SaaS environments. They act as centralized hubs that keep users informed of relevant changes, improving productivity by reducing the time spent searching for updates. Successful integration of activity feeds requires careful design to ensure relevance and personalization without overwhelming users, thereby supporting seamless information flow and enhancing user success within the application. Examples from companies like HubSpot, Atlassian, and Drift demonstrate how activity feeds can vary in design and functionality, offering personalized content, interactivity, and contextual information, all aimed at boosting user engagement and retention. However, challenges such as scaling, design complexity, and managing the signal-to-noise ratio must be addressed to prevent user frustration and maintain the effectiveness of the feed. Activity feeds, when executed well, provide substantial benefits by promoting efficient workflows and increasing user interaction, which ultimately supports both users and the product.
