Encore VS JSON-to-Go

In this tutorial you will create a REST API for a URL Shortener service using Encore for TypeScript, a new way of building fully type-safe and production-ready distributed systems in TypeScript using declarative infrastructure.

At Encore, we've made it easier by making Pub/Sub is a native component in Encore's Open Source Infrastructure SDK.

⭐️ Support the project by starring Encore on GitHub.

Very cool. Reminds me of the encore framework, also written in go: https://github.com/encoredev/encore

Need to spend some more time looking into these go based frameworks, they seem great for quick prototyping

package url import ( "context" "testing" ) // TestShortenAndRetrieve - test that the shortened URL is stored and retrieved from database. func TestShortenAndRetrieve(t *testing.T) { testURL := "https://github.com/encoredev/encore" sp := ShortenParams{URL: testURL} resp, err := Shorten(context.Background(), &sp) if err != nil { t.Fatal(err) } wantURL := testURL if resp.URL != wantURL { t.Errorf("got %q, want %q", resp.URL, wantURL) } firstURL := resp gotURL, err := Get(context.Background(), firstURL.ID) if err != nil { t.Fatal(err) } if *gotURL != *firstURL { t.Errorf("got %v, want %v", *gotURL, *firstURL) } }

For something in the same vein but for Go, there is Encore: https://encore.dev / https://github.com/encoredev/encore

The framework is Open Source and the Encore platform provides free cloud hosting for hobby projects.

Encore is a backend framework for creating cloud backend applications where infrastructure is provisioned automatically from business logic.

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.
