TypeScript Tooling

Topics

Buildinfo

Manage TypeScript incremental build cache — enable, disable, clear, and warm worktree cache for tsbuildinfo files.

•Overview

Exploring Packages

Get npm package source code locally using npm pack for reading APIs, types, and implementation.

•Overview

Benchmarking Types

Measure TypeScript type instantiations using @ark/attest — baseline expressions, type caching, and instantiation costs.

•Overview

Writing Tests

Testing conventions and TDD practices — file organization, test quality, grouping, and mandatory TDD for bug fixes.
