tsconfig/bases is a collection of shareable TypeScript configuration presets tuned for specific runtime environments.
The project solves the problem of TypeScript configuration fragmentation by providing centralized, community-maintained base configurations that developers can extend in their projects. Rather than each project crafting its own tsconfig.json from scratch, developers inherit a vetted baseline appropriate to their target environment—whether Node.js, browser, or other runtimes. This approach mirrors the model of Definitely Typed for type definitions, applying the same community-driven curation to compiler configuration.
Developers should adopt this tool if they want to avoid reinventing TypeScript configuration for common deployment targets. It suits any project that benefits from alignment with established best practices for its runtime, particularly teams that value consistency across multiple codebases. The project targets the latest stable version of TypeScript and coordinates its versioning with the target runtimes it supports, which means version numbers may not follow semantic versioning strictly.
The project maintains active community engagement, with configuration presets regularly reviewed and updated to reflect evolving TypeScript and runtime capabilities. Development follows a deliberate approach to versioning that prioritizes alignment with the ecosystems it targets over strict semver compliance.
