feat: implement npm workspaces

[ygrishajev]

This PR ensures a proper monorepo approach utilizing npm workspaces. This way we have a consistent approach to directory structure separating packages and apps.

Key Changes

1. Dockerfile Relocation for Indexer and API:

   • Dockerfiles for the indexer and api are moved to the root directory. These Dockerfiles only work in the context of workspaces with common local package dependencies. They are not transferable within the app context.

2. Transferrable Dockerfiles for Other Apps:

   • Dockerfiles for other apps remain in their respective app contexts as they are fully transferable. These can be copied elsewhere and will work independently.

3. Staged Builds for Dockerfiles:

   • Implemented staged builds in Dockerfiles for api and indexer to ensure proper Docker cache utilization and reduced image size.

Benefits

1. Dependency Unification:

   • Ensures consistent dependency versions across all apps and packages. For example, using the same TypeScript version across apps/packages allows for a single base config. This unification extends to other tools like Jest (with centralized configuration and coverage), Prettier, ESLint, and more.

2. Dependency Sharing and Deduplication:

   • Another crucial benefit is dependency sharing and deduplication, which was previously an issue.

3. Framework for Future Enhancements:

   • Provides a solid foundation for moving forward with other improvements like CI/CD. This unified approach will also streamline deployments.

4. Monorepo Orchestration Tools:

   • On top of this, we can utilize monorepo orchestration tools like Turborepo if needed.

Notes

• Next.js Builds: I haven't tested deploy-web Next.js builds as it fails for me locally due to an OS architecture mismatch. It would be helpful if someone else could try building and running these locally to ensure they work as expected.
