Tech Stack

Twenty primarily uses NestJS for the backend.

Prisma was the first ORM we used. But in order to allow users to create custom fields and custom objects, a lower-level made more sense as we need to have fine-grained control. The project now uses TypeORM.

Here's what the tech stack now looks like.

Core

• NestJS
• TypeORM
• GraphQL Yoga

Database

• Postgres

Third-party integrations

• Sentry for tracking bugs

Testing

• Jest

Tooling

• Yarn
• ESLint

Development

• AWS EKS
