Building a Real-Time Chat App with Firebase and Next.js
In this project, we take a code-first approach when working with Firestore. Instead of relying on Firestore rules or ad-hoc validation, we define the shape and structure of a valid message directly in our application code using Zod.

Build a RAG Chat App with Firebase Genkit and Astra DB
The next thing to do is write our first Genkit flow to ingest data from a URL into the collection. Flows are functions that you can run via the Genkit UI or through code. Flows have strongly defined input and output schemas using zod.

Leveraging the TS type system with APIs: Validation, error handling and free OpenAPI specs
Zod seems to be the go-to validation library, and is very useful in some contexts, for example if you need to do more complex or nested runtime validation. But this won't generate API docs or give you error handlers or API controllers.

TypeScript Types Lie & How to Improve Them
Leveraging type narrowing helper libraries like Zod or ArcType can significantly both reduce the type narrowing you need to do know parsing outside data, reduce lots of boilerplate type narrowing code, and increase type safety. Many of the type lies TypeScript tells are from JSON.parse, converting Errors typed as unknown, or when reading local configuration files. This is where Zod/ArcType can really make a huge positive impact.

Generating & Building The OpenAI SDK With Stainless & Speakeasy
While Speakeasy also includes unit tests, they're organized at the root of the /tests directory with less granular separation. Its approach emphasizes documentation and type definitions, with extensive model documentation in /docs/models/. The SDK uses runtime validation through zod, which requires developers to carefully handle error objects when the API returns invalid data. This creates a different balance between compile-time and runtime type safety.

Build a Datadog alternative in 5 minutes
I used zod-bird to integrate Tinybird APIs (pipes and events) with Next.js. It's a wrapper around the Tinybird APIs that validates pipe results using zod schemas.

JavaScript schema library from the Future 🧬
One of the most basic applications of ReScript Schema is parsing - Accepting unknown JavaScript data, validating it, and returning the result of your desired type. There are dozens of such libraries, and the most popular ones are Zod, Valibot, Runtypes, Arktype, Typia, Superstruct, Effect Schema, and more. Also, even though this is slightly different, validation libraries like Ajv, Yup, and others also stand really close.

Error Handling for fetch in TypeScript
…but that’s a lot of no fun, dangerous work. Better to use a library that has already solved this problem like Zod or ArkType. It’ll ensure the types match up, and if not, give you an error response that _somewhat_ gives you a clue as to why the decoding went wrong, way more thorough and verbose than JSON.parse’s not so great runtime error messages.

Encoders and Decoders in TypeScript
As you can see, encoding and decoding in TypeScript can make your code safer, reduce the amount of type narrowing you need to do, especially if you use Zod. For consumers of your code and api’s, it gives them the flexibility of utilizing your API’s while providing their own types which includes their own encoders and decoders in a type-safe way. TypeScript can safely ensure all erros are typesafe, and those error scenarios are handled in developers who use your code.
