Technical Reflection: Building the Impextech Database Architecture 🏗️

The completion of the data modeling phase for Impextech represents a significant shift from standard JavaScript scripting to robust, type-safe backend engineering. Here is a breakdown of the architectural decisions and technical milestones achieved. 1. Implementing Strict Type Safety (TypeScript) The primary goal for this phase was to eliminate runtime data errors by moving to TypeScript . Schema Inference : Instead of manually maintaining separate interfaces and schemas, I utilized Mongoose's InferSchemaType . This ensures that the TypeScript compiler and the MongoDB validation rules are always in sync, providing 100% type coverage for our product and user data. IDE Support : This transition has significantly improved the development experience, offering real-time autocomplete and catching property mismatch bugs before they ever reach the execution phase. 2. Migration to ES Modules (ESM) I successfully migrated the project from the legacy CommonJS ( require ) system to modern ES Modul
