Day 15

Today I implemented full user registration with email verification.
Registration creates an inactive account and sends a verification link with a JWT token.
Verification activates the account if the token is valid and not expired,
and assigns the user to the default trial subscription […]

Day 13 (oh, really? ;))

Registration Form Implementation
I've just finished implementing a registration form with validation and language switching using Next.js and React Hook Form. Now users can register with dynamic language support (English/Polish) and data validation (email, password […]

Day 12
version 0.6.0 released
Scoped access is now enforced across all core modules. Each repository operation is tenant-aware via a shared ScopedRepository base class.

Key facts:

12 modules refactored
96 updated tests
1 shared base class (ScopedRepository) used across the board

subscriberId […]

Implemented password reset functionality using JWT:

/auth/remind-password generates a short-lived token and sends it via email

/auth/reset-password verifies the token and updates the password using bcrypt

Validation handled with class-validator.
Endpoints documented with Swagger.
Token secret […]

Day#2: Designing a Reliable Backend: Lessons from Early Infrastructure Work Building new software from scratch means making foundational decisions early — decisions that shape how maintainable, scalable, and consi...

Day 2:

Wrestled for hours with TS `project references` and `paths` in a Turbo monorepo (NestJS, ESM).
If you want global aliases like `@my-lib/foo` to *just work* across apps — skip `composite: true` and `tsc --build`.

Day#1: Building Clean, Breaking Things: The Unexpected Cost of a Global Exception Filter The goal seemed trivial: create a global ExceptionFilter to unify error responses across the backend. A quick win. A small boost in DX. W...

Day 1:
tl;dr: ESM + TS + NestJS + TypeORM is possible, but not recommended for the impatient.

Successfully bootstrapped NestJS + TypeORM + PostgreSQL stack using ESM.

Day#0: Building a Modular System from Scratch Starting a new software project from the ground up is always an exercise in balancing ambition with reality. Over the past two days, I’ve...

Day 0:
TL;DR: Set up the basic foundations for a new system: database schema finalized, core backend modules scaffolded, and initial API contracts defined.Key points:
Microservices architecture
PostgreSQL
TypeScript with ESM

#TypeScript #NestJS #Nextjs #codingdays #programming

TL;DR: Yesterday I took a break. Today I’m back – and permissions are under control :)

Spent the day designing a fine-grained permission model.
I now support 96 distinct permissions across 8 modules, 4 CRUD operations, and 3 scopes: self, group, global.

Three system roles bind these into […]

Day 7
✅ 24 test suites, 153 tests passing.

Solid coverage across service and controller layers in our modular monorepo. Strict typing (TypeScript), full DTO validation, and realistic mocks across complex relations (TypeORM).

Next: fine-tuning error handling & exploring e2e strategies […]

Day 6
TL;DR: Groups, memberships, hierarchy — all dynamic now.

Released backend v0.3.0 🎉

✅ Users can belong to multiple groups with typed roles
✅ Groups can form hierarchical or overlapping structures
✅ Roles are normalized via reference types

Built with NestJS + TypeORM. Documented via […]

Day 5
TL;DR: Continued work on backend security — role-based access is now fully wired up.

✅ Got fine-grained role-based access control fully working today.

• Roles loaded from PostgreSQL
• Injected into JWT during login
• Validated via custom `@Roles()` + `RolesGuard`
• Authenticated via […]

Throwback to when I was learning to code—I built a text-to-speech tool with the Web TTS API. Just React, no frameworks, and AI was still new.

Wonder how it’d turn out now with AI and a framework. Drop your throwback projects below! ⬇️

Course: Ansible Masterclass *Infrastructure as code* is one of the central mantras of the Devops movement. Adhering to this philosophy means that we facilitate best practices, supporting and encouraging developers to become more involved in defining configuration, thus allowing the operations team to get involved earlier in the development process. Ansible is a boon to any organisation as it is the simplest way to manage configuration by leveraging native Linux/Unix technologies such as ssh and python, but it is flexible enough to handle complex processes. Linux administrators can use their existing skills to quickly and easily begin using Ansible straight away.
