blgc stands for BuiLder.Group Community, chosen because similar names like blg, bldr and bgc were already taken.
Maintaining all libraries in a single repository keeps things simple and efficient. A monorepo allows for shared tooling, consistent versioning, and streamlined CI/CD workflows, while making cross-library changes easier. This approach simplifies collaboration and reduces overhead, ensuring all libraries remain in sync.
The only disadvantage is that it’s harder to discover individual libraries via SEO since they’re all part of one repo. However, the benefits far outweigh this limitation.
