JSON-to-Go VS quicktype

That site likely uses Matt's lib for that functionality: https://github.com/mholt/json-to-go

https://mholt.github.io/json-to-go/ is a nice tool for generating a struct definition to fit some sample JSON.

json-to-go is your friend.

JSON to struct. I use this about 100 times a day, no joke.

Do your best to get static types on everything. Play a game with yourself where interface{} is banned and try to do your work. One of the most common sources of such loosely-typed values in JSON, so I'll point out this automatic struct generator for instance. If you have questions about a specific place you don't see how to avoid interface, feel free to ask. Every once in a while I do have to reach for something like this, but it should be rare.

But given we know ChatGPT can't accurately generate structs from even moderately complex json objects why bother doing all of that legwork of verifying and chiding chatgpt, when you can just drop it into a tool like https://mholt.github.io/json-to-go/ and get a correct struct in a fraction of the time?

I use https://marketplace.visualstudio.com/items?itemName=maracko.json-to-go, which is an extension version of https://mholt.github.io/json-to-go/

I think using struct in such cases is almost always the right approach. There are tools which generates go structs from json this.

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
