Compile JSONSchema to TypeScript type declarations

Nice! Lots of tricky edge cases to do this right: there’s ambiguity in the JSON Schema spec, version-to-version changes, many popular community conventions that don’t adhere to the spec, etc. Feel free to check out the tests to understand some of these: https://github.com/bcherny/json-schema-to-typescript (shameless plug — I have maintained this library for a number of years).

jsonnet is my go-to language for anything related to configuration, after having tried json, yaml, TS, edn, and tasting dhall and toml. It addresses all problems in the article and more.

the composition strikes a good balance between extensiveness and ease of use.

the generated json leads to easy and portable data, and if you write jsonschemas from jsonnet, tools like json-schema-to-typescript [1] make it easy to import a consistent interface, and almost every language has a reasonably up-to-date validation library.

Take a look at https://github.com/bcherny/json-schema-to-typescript, too. I used it successfully at a previous job. IIRC, I had to write some code to convert OpenAPI to JSON Schema but it wasn’t onerous

If you're using OpenAPI, you could use this to generate TypeScript interfaces:

It works really well

I'm messing around with a process to convert JSON schemas to TypeScript interfaces using json-schema-to-typescript. I have a little under 900 JSON files each containing a schema, totaling about 3.5 MB.

I grab the response off of the network tab. Either make a structure manually or use something like QuickType

2. Quicktype

I have the library demo linked from the homepage bookmarked: https://app.quicktype.io/ I use it every time I need to go from a pile of JSON to TypeScript types or zod declarations.

This is a very intriguing problem!

Not trying to steal thunder, but quicktype (https://github.com/quicktype/quicktype) does all of this–JSON schema or TypeScript definitions to de/serializers and types in nearly 30 languages at this point. Try it here: https://app.quicktype.io

I usually use this tool: https://app.quicktype.io

Grab the json, paste it into https://app.quicktype.io/ and see if the structure matched your struct.

I usually use https://app.quicktype.io/ , they also have a VSCode plugin and then fieldaligment to make sure it's as compact as possible.

Just paste your json inside app.quicktype.io or it's vscode

P.S. This could be more efficient to generate Codable code than ChatGPT
