Valibot v1 – The 1 kB schema library for TypeScript (valibot.dev)
I am excited to announce the release of Valibot v1. Valibot is a modular and fully tree-shakable schema library that helps you describe and validate your data with a type-safe and easy-to-remember API. As a 1 kB alternative to Zod, Valibot is perfect for validating forms and securing backend-frontend communication with a single source of truth.

Why Go? (github.com/microsoft)
Language choice is always a hot topic! We extensively evaluated many language options, both recently and in prior investigations. We also considered hybrid approaches where certain components could be written in a native language, while keeping core typechecking algorithms in JavaScript. We wrote multiple prototypes experimenting with different data representations in different languages, and did deep investigations into the approaches used by existing native TypeScript parsers like swc, oxc, and esbuild.

Bundling MCP Servers in Every OpenAPI –> TypeScript SDK (speakeasy.com)
It’s no longer enough for businesses to make their services available to developers. A great development experience also hinges on the ability for AI to access and integrate with available APIs. That’s why starting today, every TypeScript SDK generated by Speakeasy now bundles a runnable Model Context Protocol (MCP) (opens in a new tab) server enabling you to expose your API to the growing landscape of AI agents.

How to Implement a Cosine Similarity Function in TypeScript (alexop.dev)
To understand how an AI can understand that the word “cat” is similar to “kitten,” you must realize cosine similarity. In short, with the help of embeddings, we can represent words as vectors in a high-dimensional space. If the word “cat” is represented as a vector [1, 0, 0], the word “kitten” would be represented as [1, 0, 1]. Now, we can use cosine similarity to measure the similarity between the two vectors.

Node just added TypeScript support (deno.com)
Node.js recently added native TypeScript support in version 22.6 (stabilized in 23.6), a welcome enhancement simplifying setups for TypeScript users. This has sparked questions within the community about how Node’s new capabilities compare with Deno’s existing TypeScript integration.

An ode to TypeScript enums (disintegrator.dev)
It’s official, folks. TypeScript 5.8 is out bringing with it the --erasableSyntaxOnly flag and the nail in the coffin for many of the near-primordial language features like Enums and Namespaces. Node.js v23 joined Deno and Bun in adding support for running TypeScript files withouth a build step. The one true limitation is that only files containing erasable TypeScript syntax are supported. Since Enums and Namespaces (ones holding values) violate that rule since they are transpiled to JavaScript objects.
