PubNub MCP Server

# How to Write a PubNub App Checklist The following checklist outlines the steps to create a PubNub-powered application without needing to rely on any third-party services or libraries. This guide is designed for developers who want to build a real-time application using PubNub’s Data Stream Network and their SDKs and custom code where needed. • PubNub Account Setup and API Key Configuration - Create a PubNub account: – Go to PubNub’s official website and sign up with a valid email address. – Verify your account if prompted, and log in to the PubNub dashboard. - Create a new application on PubNub: – In the dashboard, navigate to the “Apps” section and create a new app. – Provide a descriptive name for your app to easily identify it later. - Generate PubNub API keys: – From within your newly created app, click on the “Keyset” section. – Obtain the publish and subscribe keys for both development and production environments. – (Optional) Create multiple keysets for separate environments or microservices. - Configure key properties: – Assign secure permissions or tokens (using PubNub Access Manager if needed). – Enable PubNub features (e.g., Presence, Storage & Playback, Functions) that match your project requirements. - Store and manage your keys securely: – Do not embed API keys in publicly visible repositories. – Use environment variables or secure configuration management to protect your credentials. • Project Scope Definition - Clearly define the purpose and objectives of the PubNub-powered application. - Enumerate the specific real-time communication features and functionalities (e.g., messaging, presence, push notifications). - Decide on the platforms (web, mobile, desktop) the application will target, using PubNub exclusively. - Outline success criteria, performance requirements (e.g., latency, concurrency limits), and key deliverables. • Technology Stack Selection - Confirm PubNub as the sole real-time data stream network provider. - Choose programming languages, frameworks, or libraries that integrate well with PubNub (e.g., React, Vue, Angular, Swift, Kotlin). - Ensure all required functionalities (authentication, backend, etc.) can be built without needing to add extra third-party services. - Evaluate PubNub SDK versions for compatibility and up-to-date features. • User Interface (UI) and User Experience (UX) Design - Define design guidelines and layout, emphasizing a seamless real-time experience (e.g., chat updates, presence indicators). - Outline user flows, focusing on interactions with real-time events (e.g., notifications, live feed updates). - Incorporate accessibility features such as keyboard navigation and screen reader support. - Plan for handling disconnections or offline states gracefully in the UI. • Data Design - Determine if a local or on-device storage solution is needed for caching or offline mode. - For persistent data, plan whether you will use PubNub Storage & Playback or another self-hosted solution. - Devise naming conventions for channels and handle real-time data streams effectively. - Ensure data integrity and performance requirements without introducing additional third-party data services. • Backend Development - Assess whether you need additional server-side logic beyond PubNub’s Data Stream Network and Functions. - Utilize PubNub Functions or your own infrastructure to handle custom message manipulation or routing. - Define the channels, events, and triggers that orchestrate the app’s workflows. - Document any server-side APIs needed (e.g., for user authentication) that rely solely on your own systems or built-in PubNub features. • Testing - Establish unit tests to verify PubNub message payload formats, channel connections, and presence events. - Develop integration tests ensuring the UI responds correctly to real-time events (e.g., newly received messages). - Use separate PubNub development keysets for staging and production environments. - Conduct load testing to evaluate performance under high traffic and concurrency scenarios. • Deployment - Choose your hosting solution for any required server (e.g., self-managed servers, cloud VM). - Configure PubNub production keys and environment variables. - Define a continuous integration and deployment (CI/CD) process for code updates and fixes. - Document build steps or containerization (e.g., Docker) if applicable. • Security Measures - Use PubNub Access Manager (PAM) to control access and permissions for channels. - Ensure secure connections with TLS/SSL and consider message encryption if needed. - Implement a token-based authentication flow or your own sign-in process without needing external identity providers - Apply secure coding practices for any server or client logic to safeguard against potential vulnerabilities. • Maintenance and Support - Monitor PubNub library updates and stay informed on new releases or security patches. - Devise an internal logging and analytics approach (e.g., your own tools) to track errors, usage metrics, and performance. - Establish a feedback loop for users to report issues and request features. - Maintain comprehensive documentation so developers, administrators, and end-users can understand and support the PubNub-powered features.
