Mastering CRUD Operations with Knex.js and PostgreSQL
https://www.reddit.com/r/programming/comments/1la77oe/mastering_crud_operations_with_knexjs_and/
<!-- SC_OFF -->Knex.js is a powerful, open-source SQL query builder for Node.js that simplifies database interactions by allowing developers to write database queries using JavaScript. In this article, we'll explore how to perform CRUD (Create, Read, Update, Delete) and various other operations using Knex.js with a PostgreSQL database. <!-- SC_ON --> submitted by /u/ram-foss (https://www.reddit.com/user/ram-foss)

Execute code snippets in isolated containers.
https://www.reddit.com/r/programming/comments/1l9ptba/execute_code_snippets_in_isolated_containers/
<!-- SC_OFF -->I wanted to share a project I've been working on called Taylored Snippets Web. It's an Angular-based web application that lets you create, manage, and run code snippets in a worksheet-style interface. The main goal was to create a secure and isolated environment for code execution for each user. Key Features Isolated Execution: The application has two distinct modes that can be launched using Docker Compose profiles: Multitenant Mode: This is the core feature. It uses a Node.js orchestrator service to spin up a dedicated, isolated Docker container for each user session. This ensures that one user's code can't interfere with another's. Singletenant Mode: A simpler mode for local development that uses a single, shared runner instance for all users. Broad Language Support: The runner can execute code in a wide variety of languages using shebangs, including python3, node, bash, java, ruby, php, and more. Snippet Management: Users can add both text snippets (for annotations) and compute snippets (for executable code) to a worksheet. These can be reordered on the page via drag-and-drop. Live Output: Standard output and errors from code execution are displayed directly in the UI. Tech Stack Frontend: Built with modern Angular using standalone components, zoneless change detection, and Angular Material for the UI. Backend: A Node.js/Express Orchestrator that uses dockerode to manage the lifecycle of runner containers. A Node.js Runner that executes code snippets and communicates results. Communication: Real-time communication between the frontend and the runner is handled with Socket.IO. Deployment: The entire stack is defined in a docker-compose.yml file, making it easy to launch with either the multitenant or singletenant profile. I've put a lot of work into the architecture and would love to hear your thoughts or answer any questions about the implementation. The repo has all the source code, including the CI workflow and Docker setup. <!-- SC_ON --> submitted by /u/sasizza (https://www.reddit.com/user/sasizza)

Secret to 100% Type-Safe TypeScript - tRPC eliminated our API type hell
https://www.reddit.com/r/programming/comments/1l9dcsc/secret_to_100_typesafe_typescript_trpc_eliminated/
<!-- SC_OFF -->After years of fighting with the disconnect between my frontend and backend types, I finally discovered tRPC, and it's been a complete game-changer for me. Before tRPC, I tried everything: Manual type synchronization (tedious and error-prone) REST with OpenAPI/Swagger (clunky build steps and generated code) GraphQL with code generation (powerful but complex for our needs) With tRPC, I've eliminated 100% of our API type errors. No more runtime surprises, no more manual type duplication, just seamless end-to-end type safety. The developer experience is incredible - full autocomplete, instant feedback when backend types change, and virtually no runtime overhead. I wrote about how technical frustrations like API type hell contribute to developer burnout in my article The tRPC Secret to 100% Type-Safe TypeScript : Stop API Type Hell (https://beyondit.blog/blogs/The-tRPC-Secret-to-100-Type-Safe-TypeScript). Has anyone else here made the switch to tRPC? What's been your experience? For those who haven't tried it yet, what's your current approach to the TypeScript API type problem? <!-- SC_ON --> submitted by /u/WillingnessFun7051 (https://www.reddit.com/user/WillingnessFun7051)
