Developer Releases Angular 21 + .NET 10 Auth Template with Live Demo and Multi-Channel 2FA

·1 views

A developer has published an open-source authentication starter template combining Angular 21 and .NET 10, featuring local auth and multi-channel two-factor authentication via TOTP, email, and SMS out of the box. The template includes a live demo deployed on Google Cloud Run, allowing users to test registration, 2FA setup, and password reset using the exact code shipped in the template. To keep reusable logic maintainable across generated projects, core authentication and notification functionality was extracted into two dedicated NuGet packages that receive updates independently. Local development requires no real third-party messaging accounts, as mock servers for SendGrid, Postmark, and Twilio are provided as public container images. The entire demo runs at zero cost using Aiven's free MySQL tier and scale-to-zero Cloud Run services, avoiding any paid infrastructure or expiring trial credits.

Queue Depth-Based Router Proposed to Stop Secret Prompts Leaking to Cloud

A workflow proposal suggests that AI coding agents on shared workstations need a router that classifies prompts before deciding where to send them. The problem arises when local GPU queues become congested, prompting developers to redirect all requests — including those containing sensitive data like API keys — to remote hosted endpoints. The proposed router uses four signals — secret classification, local queue depth, offline status, and a wait-time budget — to determine whether a prompt should be processed locally or remotely. Only prompts classified as non-secret are permitted to leave the machine, and only when local waiting would exceed a defined time threshold. The design prioritises explainability and auditability, with each routing decision stored as serialisable JSON so incident reviews can trace exactly why a prompt was sent off-device.

How to Spot and Fix Fail-Open Defaults in AI-Generated Code PRs

AI agent-generated pull requests can introduce unverified default values — such as hardcoded URLs and timeout figures — that have no traceable source in the existing codebase. A key risk is 'fail-open' behavior, where error-handling code silently returns a success response even when a critical service like billing is unreachable. Reviewers are advised to audit every new environment variable, endpoint, and return shape introduced by an agent patch, building a provenance table that cites a verified source for each default or strips it entirely. Automated scanning scripts and targeted regex searches can help surface swallowed errors and invented fallback values that visual review might miss. The recommended standard is fail-closed behavior by default, meaning errors should throw exceptions rather than return false success signals, unless a written SLA explicitly permits deferral.

JSON.stringify Edge Cases That Silently Break Production JavaScript Apps

JavaScript's JSON.stringify is widely used but carries several silent failure modes that can cause hard-to-trace production bugs. Undefined values, functions, and Symbols are quietly dropped from objects or converted to null in arrays, with no error or warning thrown. Special numeric values like NaN and Infinity are all serialized as null, erasing their original meaning, while Map and Set objects serialize as empty objects by default. Dates serialize correctly only because they implement a toJSON method, a hook developers can use in their own classes. BigInt values are the exception, triggering an outright TypeError rather than a silent conversion, making them easier to catch but still a common stumbling block.

Developer Builds Open-Source Library for Particle-Based DOM Element Animations

A developer has released Vanilla Disintegrate, an open-source JavaScript library that animates the removal and restoration of DOM elements using particle effects, inspired by the so-called 'Thanos snap' effect seen in messaging apps. The library is framework-agnostic and works directly with standard DOM elements, requiring no special markup or mandatory CSS files. It ships with ready-to-use presets and an interactive web playground where developers can fine-tune particle movement, timing, and sound before copying the generated configuration into their code. The project grew out of a real-world 'remove from favorites' interaction problem the developer encountered at work, where common fade and scale animations felt too familiar to be memorable. Custom rendering support is also available for developers who need to go beyond the built-in particle renderer.
