Developer releases OTI, an open-source one-time secret sharing app built with AdonisJS 6

·1 views

A developer named Oguzhan Karacabay has released OTI, a free open-source app that lets users share messages or small text files via a one-time-use link. The message is encrypted in the browser, with only encrypted data stored on the server and the private key embedded in the link itself. Key features include password protection, QR sharing, encrypted .txt file support up to 100 KB, an expiry countdown, and a confirmation step to prevent chat previews from accidentally consuming the link. The project was built using AdonisJS 6, TypeScript, MySQL, Redis, and Vite, with an AI coding assistant used for parts of the implementation. The code is MIT licensed and available on GitHub, though the developer notes it has not undergone a professional security audit.

Developer Builds Immersive Scroll Narrative Landing Page for Fictional Indonesian Restaurant

A developer has completely redesigned a fictional Indonesian comfort food restaurant landing page called Rasa Kenangan, meaning 'Flavor of Memories', set in Yogyakarta. The project was built using only vanilla HTML, CSS, and JavaScript with no frameworks or backend, and is deployed statically on Cloudflare Pages. The redesign replaced a generic hero-and-grid layout with an immersive scroll-driven experience featuring parallax animations, sticky storytelling sections, and a draggable horizontal menu. Design inspiration was drawn from Awwwards-winning restaurant websites such as BALANS KITCHEN and CAÍN, with a warm amber and charcoal color palette using modern oklch color space. The finished page achieved a perfect Lighthouse score of 100 across performance, accessibility, best practices, and SEO.

How Angular Developers Can Build Smart Objects Using NgRx SignalStore Enrichment

A technical guide published on DEV Community explains how Angular developers can move beyond passive data containers by transforming raw API responses into Smart Objects using a Factory Mixin pattern called Object Enrichment. The approach involves extending plain TypeScript data interfaces with domain methods such as fullName() and hasRole(), making business logic self-contained and immediately discoverable via IDE autocomplete. The article argues that enriching data at write time—when it enters the NgRx SignalStore—is architecturally safer than enriching it at read time via computed() signals, since the latter still exposes raw state to components that bypass the enriched layer. Angular's Dependency Injection constraints within the store are addressed using the runInInjectionContext utility. A working implementation is available on both GitHub and StackBlitz for developers to explore directly.

Dart Developers Can Now Build ADK Agents and MCP Servers Without Python or Node.js

A new open-source project demonstrates how Dart developers can build AI agents and Model Context Protocol (MCP) servers using the unofficial adk_dart library and the Shelf HTTP framework, without relying on Python or Node.js. The repository, adk-hello-world-dart, includes two examples: a CLI agent using ADK's LlmAgent with a registered function tool, and a Shelf server exposing an MCP-compatible greeting tool over Server-Sent Events. The server handles JSON-RPC routing through a SessionService component and supports core MCP methods such as initialize, tools/list, and tools/call. The project targets Dart 3.5 or later and is intended as a practical workaround, as no official Dart ADK had been released as of July 2026. The author notes that the transport and JSON-RPC implementation are intentionally minimal and not designed as a general-purpose MCP server.

GTM Engineering Is Systems Design — and Most Teams Are Building It Wrong

Go-to-market (GTM) engineering, a role that barely existed two years ago, is now a staple in growth team hiring plans, with US salaries commonly ranging from $110,000 to $180,000. At its core, the role involves building automated pipelines that convert raw prospect data into sales conversations with minimal human intervention, using tools like Clay, n8n, and increasingly LLM agents. According to Daria, a 12-year developer-tools GTM veteran and founder of GTM Labs, the standard high-volume outreach architecture fails when targeting developer audiences, who are technically savvy, distrust marketing language, and readily identify templated messages. She argues that effective GTM systems for technical buyers should prioritize high-quality behavioral signals over contact volume, and distribute trusted artifacts like benchmarks and documentation rather than automated email sequences. Developers considering a career pivot into GTM engineering hold a natural advantage, she notes, because they already understand how these systems work and can judge which automations are genuinely useful.
