TypeScript Community Chooses Best Libraries of the Year: 2024 Awards Results

The annual «TypeScript Community Awards» has announced the voting results, with over 15,000 developers from around the world participating. This year, the community recognized libraries that significantly simplify TypeScript development, improve performance and code safety. We have compiled the top 5 winners that everyone working with this language should explore.

1. Zod — Best Library for Data Validation

Zod confidently took first place in the «Schemas and Validation» category. This library allows you to declaratively describe data structures and automatically check their compliance with TypeScript types. The main advantage is full integration with the type system: when the schema changes, types update automatically. Developers noted that Zod makes code more predictable and eliminates many runtime errors.

Support for complex nested schemas
On-the-fly TypeScript type generation
Works with both frontend and backend

2. tRPC — Best Tool for API

tRPC received the «Library of the Year» award for its revolutionary approach to building APIs. Instead of REST or GraphQL, tRPC offers fully typed function calls between client and server. This means TypeScript types are automatically synchronized between backend and frontend, eliminating mismatches. According to reviews, tRPC reduces API development time by 40%.

Automatic typing of requests and responses
Support for React, Next.js, Express
No need to write schemas or documentation

3. Prisma — Best ORM for TypeScript

Prisma once again confirmed its status as a favorite among ORMs. It provides a declarative language for describing database models and automatically generates a typed client. Developers highlighted convenient migrations, IDE autocompletion, and support for PostgreSQL, MySQL, SQLite. Prisma also offers the Prisma Studio visual editor for working with data.

Type-safe database queries
Built-in support for relations and aggregations
Client generation for a specific schema

4. Vitest — Best Testing Framework

Vitest surpassed Jest and Mocha in the «Testing» category. This library uses Vite under the hood, providing lightning-fast test execution and hot reload on changes. Vitest supports TypeScript out of the box and is compatible with most existing test suites. The community appreciated its ease of setup and CI/CD integration.

Up to 10x faster than Jest
Support for ESM and CommonJS
Built-in coverage report

5. Effect — Best Library for Functional Programming

Effect was the discovery of the year. This library provides tools for working with side effects, error handling, and concurrency in a functional style. Developers noted that Effect makes code more predictable and testable, especially in complex systems with asynchronous operations.
