I will migrate your expressjs API to nestjs
Charles A
About this gig
Do you have an existing Express.js API that you want to migrate to NestJS?
I will migrate your Express.js backend to NestJS while preserving your existing API functionality and working with your current database setup.
What I can migrate:
- Express.js routes and endpoints
- Controllers and business logic
- Middleware and authentication
- Database integration
- API validation and error handling
- Project structure and configuration
The goal is to give your existing backend a cleaner, organized NestJS structure without unnecessarily changing how your API works.
Please message me before ordering so I can review your project and confirm the migration scope.

FAQ
Can you migrate any Express.js API to NestJS?
I can migrate most standard Express.js APIs, but project complexity varies. Please contact me before ordering so I can review your project and confirm the scope.
Will my existing API functionality be preserved?
Yes. The goal of the migration is to move your existing API functionality to NestJS while keeping the existing behavior and endpoints working as agreed.
Can you work with my existing database?
Yes. I can connect the migrated NestJS application to your existing database setup. Database redesign or data migration between database systems may require a custom offer.
Does the endpoint limit include all API routes?
Yes. The package endpoint limit applies to the API endpoints included in the migration. Additional endpoints can be discussed if your project exceeds the selected package.
What do you need before starting the migration?
I will need access to the Express.js project source code and relevant setup information such as the package configuration, environment variables, database details, and any specific requirements for the migration.
