YouValidateMe JSON Schema library server project built on this library

[crowdwave]

Hello I thought you might be interested, I built a JSON schema library server and it is using your library for its core.

https://github.com/crowdwave/youvalidateme

I started with a different JSON Schema library for Go but I switched to yours as your has more features and seems more actively maintained.

Thanks!

@crowdwave happy to hear that

you might want to try v6.0.0-beta1 from https://github.com/santhosh-tekuri/jsonschema/tree/boon

this has some new features. note that api is slightly different since it is major version bump

Thanks.

Yes I'm having some trouble getting schemas to valid against any of the drafts is there documentation for the new syntax?

What I would really appreciate is this example extended further to show how to validate schemas against the various Draft specs and also how to Compliler.LoadURL and validate.

https://github.com/santhosh-tekuri/jsonschema/blob/boon/example_regexp_test.go

All I need to do is use version 6 with the ECMA regex plus, valid schemas against drafts and valid JSON against schemas.

Is there an example that ties all that together into some example code?

thanks!

as per specification $schema keyword specifies which draft to be used for the schema.

if the schema does not has $schema then the library is free to chose whatever draft it wants to. Currently this library default to latest draft in such cases. In case you want to force to use draft6 you can do compiler.DefaultDraft(jsonschema.Draft6)

in your project you run the server:

./youvalidateme --port 8080 --schemas-dir=/path/to/schemas

so you want to read all schema files only from the path specified by user and you don't want to expose any system file path to user. with 6.0.0-beta1 you can do it as follows:

we want to introduce custom url for this; for example schemas:///dir1/dir2/test.json will translate to /path/to/schemas/dir1/dir2/test.json

type dirLoader string

func (l dirLoader) Load(url string) (any, string) {
    path, ok := strings.CutPrefix(url, "schemas:///")
    if !ok {
        return nil, fmt.Errorf("unsupported url: %v", url)
    }
    path = filepath.join(string(l), path)
    f, err := os.Open(path)
    if err!=nil {
        return nil, err
    }
    defer f.Close()
    return jsonschema.UnmarshalJSON(f)
}

func testLoader() {
       c := jsonschema.NewCompiler()
       c.DefaultDraft(jsonschema.Draft6)
       c.useLoader(dirLoader("/path/to/schemas"))

      // to compile a particular schema
      c.Compile("schemas:///dir1/dir2/test.json")
}
