🧱 Build the Backend First: A Better Way to Start SaaS

Developers often fall into the trap of focusing too much on frontend design before building the backend, which can lead to burnout and delays in launching the actual product.
The 'Backend First' approach suggests starting with building the backend components like API, authentication system, data model, and logic, even before creating a UI.
Backend-First approach offers advantages in terms of speed to MVP, product validation based on logic, stable APIs, and prioritizing value over UI for monetization.
A step-by-step guide is provided for building a SaaS backend in a weekend using tools like Fastify or Express, PostgreSQL, Prisma, and Stripe for monetization.
The example of building a 'SEO Crawler API' in 5 steps is showcased, emphasizing defining core features, building REST API, integrating authentication and billing, and documenting with API docs.
Monetization strategies like usage-based billing through Stripe are recommended to be implemented before focusing on UI design, emphasizing the importance of the backend functionalities.
Starting with a 'No UI SaaS' model can help in validating the product early based on API features, setting different plans based on usage quotas and pricing.
The article suggests delaying frontend development and focusing on delivering value through APIs first, indicating that the frontend can be minimal or added later after backend is established.
Backend-First project ideas are shared, highlighting the importance of an API-first approach and showcasing projects like JSON Optimizer API, AI Summary API, and Cron Job API.
The article advocates for a shift in developer culture towards prioritizing core logic, security, and developer experience over design elements, highlighting the significance of backend development.
The TL;DR emphasizes building the backend first, shipping it as a usable API, and focusing on providing value to users through functionality rather than just aesthetics.

Grow a Dev Knowledge Garden 🌱 Not Just a Toolset

Dev Resources offers a new approach to grow developer tools and tutorials like a garden for increased productivity and knowledge retention.
The Dev Garden concept involves planting, organizing, cultivating, and harvesting knowledge assets to enhance coding skills.
Seeds in this 'knowledge garden' can be code snippets, CLI commands, frameworks, tutorials, or saved solutions.
Tools like Notion, Obsidian, and Dendron aid in capturing, organizing, and structuring the planted ideas.
Regularly revisiting notes, refactoring snippets, and creating from the gathered knowledge are crucial phases for skill enhancement.
One should also compost failed ideas and unused frameworks to learn from mistakes.
By building a 'second brain' and creating reusable mental models, developers can transition from chaos to clarity in their work.
The Dev Garden philosophy advocates for slow, thoughtful, and creative coding practices, emphasizing the importance of craftsmanship.
Emojis are used humorously throughout the article to depict various stages and experiences of tending to a developer's garden.
The article also highlights premium bundles and quick kits for developers seeking financial independence through their creations.

How Languages Hack Your Brain (and What to Do About It)

Programming languages act as thought frameworks and shape problem-solving approaches.
Different languages teach distinct mental models and affect how you reason and code.
Python prioritizes readability, while C focuses on memory management and control.
Go emphasizes simplicity in concurrency, while Haskell values pure functions.
JavaScript embraces diversity, but may lead to chaotic architectures.
Exploring languages you avoid can provide insights into your comfort zones and preferences.
To improve, deliberately learn languages that challenge your current thinking.
Engaging in diverse projects helps in rewiring your mental model with new perspectives.
Creating a language learning map and auditing main stack assumptions aid in intentional growth.
Programming languages are like mental prosthetics that influence your thinking processes.
To enhance problem-solving skills, rotating through different languages intentionally is recommended.

Vibe Coding: ″Feel pain. Accept pain.‶

The author was initially skeptical about vibe coding and only used LLMs for a small portion of the code, but found them helpful for bug fixes, new domains, and quick answers.
When building a Phoenician transliteration tool in ReactJS without prior ReactJS knowledge, the author found success using ChatGPT for crafting prompts and generating code, but faced challenges during deployment.
Issues arose during website deployment as ChatGPT and Cursor couldn't provide a complete list of libraries, leading to manual library installations and debugging.
Despite successfully deploying the site, the author realized the importance of investing time in learning React properly to avoid debugging and improve code structure, highlighting the need to treat LLMs like a Lego toolkit for code generation.
