Automating API Documentation: A Journey from TypeScript to OpenAPI and Schema Governence with Optic
3. Generate JSON schemas with the ts-json-schema-generator package

Is using zod as the primary source of truth for Typescript types sensible/sustainable?
We user ts-json-schema-generator to create the schemas directly from TS types.

Validating JSON parser that uses TS as the spec format?
I’ve been using this one: https://github.com/vega/ts-json-schema-generator most recently and it’s been great

Transpiling Typescript into Rust
Maybe this vscode extension can work for you. It can turn Json samples into structs. this can help you turn typescript to Json. Maybe you can automate it.

Game engine in web - part 2 - data oriented system
Now we have to parse the JSON containing our scene and validate that this JSON is valid according to what we expect. For that we are going to use the JSON Schema along with ts-json-schema-generator to generate said schema automatically and ajv to validate JSON against the generated schema.

Is there a tool to visualize all of the value-types of a highly abstracted interface/type?
If the output format isn’t important you could use ts-json-schema-generator - it doesn’t work with everything but it’s pretty good at outputting a json schema structure for interfaces and types.

6 Reasons why JSON Schema is worth your time
In the JavaScript ecosystem you can use the excellent AJV package to validate any JavaScript object against a JSON schema. This is especially useful to ensure that API contracts are maintained when communicating with other services.

Migrate Your Express Application to Fastify
Since Fastify supports schema validation with Ajv, the validate module is no longer required on the /shorten route, and we can specify the JSON schema directly on the route. The controllers for both routes will largely remain the same, except that the res parameter is renamed to reply as before:

Has anybody used Typia library?
There's a ton of schema validators out there and most devs have their personal favorite. Mine was zod and is now typebox + ajv.

Accept only specific keys in JSON or form-data format in express?

Advanced Fastify: Hooks, Middleware, and Decorators
Fastify uses JSON schema to define the validation rules for each route's input payload, which includes the request body, query string, parameters, and headers. The JSON schema is a standard format for defining the structure and constraints of JSON data, and Fastify uses Ajv, one of the fastest and most efficient JSON schema validators available.

Getting Started with Fastify for Node.js
In Fastify, JSON schema validation is a built-in feature that allows you to validate the payload of incoming requests before the handler function is executed. This ensures that incoming data is in the expected format and meets the required criteria for your business logic. Fastify's JSON schema validation is powered by the Ajv library, a fast and efficient JSON schema validator.

How can we map data from JSON to typescript object efficiently?
I think you're looking for a json schema validator like Ajv or Zod.

5 useful JSON tools to improve your productivity
We can use JSON Schema to validate that our data adheres to a specific structure. Ajv is one popular validator tool for JavaScript applications that allows us to create a schema and then validate JSON against that schema. Here's an example of using Ajv to validate one of the above JSON examples against a schema:

Ask HN: JSON API object type definitions and validation in 2023?
Hey HN,
We're designing a new system and have been kicking the can about JSON object definitions and validation. Soon we need to settle on a system to validate API request bodies and provide helpful error messages.
In the past, I've used JSON Schema ( https://json-schema.org/ ) to define definitions and ajv ( https://ajv.js.org/ ) to validate, but it's a bit verbose and ajv validation errors are more cryptic than I'd like to deal with.
TypeSchema looks interesting. It seems solid (and perhaps stable?), but development hasn't been active for 2 years. It also looks like we'd still need to generate JSON Schema and choose a validation library
Anyway, I'm very curious how others are approaching this problem. How do you organize and generate validations for your type definitions? What libraries do you use to validate and provide human readable error messages?
Thank you!
