Practical guides for modern devs. ### [Zod: TypeScript-First Schema Validation for Any Runtime](https://devtoolsguide.hashnode.dev/zod-typescript-first-schema-validation-for-any-runtime?utm_source=hashnode&utm_medium=feed) TypeScript gives you static type checking at compile time. Zod solves the complementary problem: validating data at runtime that comes from outside TypeScript's control — HTTP request bodies, API responses, environment variables, user input, and conf... 5 min read · [devtoolsguide.hashnode.dev](https://devtoolsguide.hashnode.dev/zod-typescript-first-schema-validation-for-any-runtime?utm_source=hashnode&utm_medium=feed) [Mar 4](https://hashnode.com/posts/zod-typescript-first-schema-validation-for-any-runtime/69a826ba709cf06761a2a1b2) ### [WezTerm: A GPU-Accelerated Terminal Configured in Lua](https://devtoolsguide.hashnode.dev/wezterm-a-gpu-accelerated-terminal-configured-in-lua?utm_source=hashnode&utm_medium=feed) WezTerm is a terminal emulator that takes the approach that your terminal should be as configurable as your text editor — using code, not a settings panel. Configuration is written in Lua, every behavior is programmable, and the multiplexer (tabs, pa... 5 min read · [devtoolsguide.hashnode.dev](https://devtoolsguide.hashnode.dev/wezterm-a-gpu-accelerated-terminal-configured-in-lua?utm_source=hashnode&utm_medium=feed) [Mar 4](https://hashnode.com/posts/wezterm-a-gpu-accelerated-terminal-configured-in-lua/69a826b9187dd2342a00373f) ### [Vitest: Fast Unit Testing for Vite-Based JavaScript Projects](https://devtoolsguide.hashnode.dev/vitest-fast-unit-testing-for-vite-based-javascript-projects?utm_source=hashnode&utm_medium=feed) Jest has been the default JavaScript test runner for years. But it was designed for CommonJS and requires significant configuration to handle modern ESM, TypeScript, and Vite projects. Vitest was built from the start for the modern JavaScript ecosyst... 5 min read · [devtoolsguide.hashnode.dev](https://devtoolsguide.hashnode.dev/vitest-fast-unit-testing-for-vite-based-javascript-projects?utm_source=hashnode&utm_medium=feed) [Mar 4](https://hashnode.com/posts/vitest-fast-unit-testing-for-vite-based-javascript-projects/69a826b8709cf06761a2a1b0) ### [TypeSpec: API Design Before Code](https://devtoolsguide.hashnode.dev/typespec-api-design-before-code?utm_source=hashnode&utm_medium=feed) Most teams design APIs one of two ways: write code first and extract OpenAPI from annotations, or write OpenAPI YAML directly and generate types from it. Both have the same problem — you end up maintaining two things (schema + code) that need to stay... 4 min read · [devtoolsguide.hashnode.dev](https://devtoolsguide.hashnode.dev/typespec-api-design-before-code?utm_source=hashnode&utm_medium=feed) [Mar 4](https://hashnode.com/posts/typespec-api-design-before-code/69a826b6187dd2342a00373d) ### [tRPC: End-to-End Type-Safe APIs Without the Ceremony](https://devtoolsguide.hashnode.dev/trpc-end-to-end-type-safe-apis-without-the-ceremony?utm_source=hashnode&utm_medium=feed) tRPC: End-to-End Type-Safe APIs Without the Ceremony Most API architectures have a type safety gap: your backend has TypeScript types, your frontend has TypeScript types, but the wire between them is untyped.
