Definitely an improvement! Left some notes.

Per our discussion, can we just store the whole of core here. I think that's generally more useful.

have exposed a core via kibana_service.ts https://github.com/elastic/kibana/pull/59881/files#diff-9da56dd30eec66800d99e2aa39faf33e

  const decoded = OverviewFiltersType.decode(responseData);

-  ThrowReporter.report(decoded);
+  PathReporter.report(decoded);


Does this do anything? IIRC Throw reporter issues a throw, while PathReporter returns a value like what's shown here: https://github.com/gcanti/io-ts#error-reporters . I don't think we should be making this change, which is unrelated, in this PR.

ThrowReporter is deprecated.

Good to know. That said, I think we'll need throw new Error(PathReporter.report(decoded)) the code as-is just generates a string and throws it away.

we don't need to throw it, because we are not catching it. We are only checking for errors now.

Same comment here, let's stick with the ThrowReporter. Let's not mix too many things into one PR unless there's an issue with separating them out.

Are we trying to make Kibana's fetch more like window.fetch where errors are thrown instead of returned?

have updated this.

Left a comment regarding io-ts usage for api requests.

+    return ApiService.instance;
+  }
+
+  public async get(apiUrl: string, params?: HttpFetchQuery, decodeType?: any) {


I think it would be better to require the decodeType parameter. We could then describe decodeType better than any. If we did something like:

import { Decoder } from 'io-ts'

Suggested change

public async get(apiUrl: string, params?: HttpFetchQuery, decodeType?: any) {

public async get<T>(apiUrl: string, params?: HttpFetchQuery, decoder: Decoder<unknown, T>) {

In this case, T will be the type we get when isRight is truthy, and unknown is the type we specify for the value we give to PathReporter (which is ok, because decode will return an object of type Either<t.Errors, T> anyway, so the reporter will be happy).

Partial, Type, Intersection, etc., all seem to extend the Decoder interface, so I think this would be a safe assumption for us to make here.

Then, if we define a complex type like:

const MyComplexType = t.intersection([ t.partial({ foo: t.string, }), t.type({ bar: t.number, }), ]);

..the usage of the function will remain the same, but our responses will be typed appropriately:

const apiResponse = apiService.get('/api/pathToComplexType', { foo: 'bar' }, MyComplexType);

And the resultant object will be typed like:

If we allow the decodeType parameter to be optional, we can only ever guarantee a return type of any; this is more-or-less what we've always done, but the idea of type safety at runtime and "automatic" typing for all API responses sounds very nice to me.

If we feel it's out of the scope of this PR, a tech debt follow-up issue would be ok by me too, if we are agreed this is something we'd want.

I created #60395 to track the addition of this. I think this will be a nice add when we can get to it.
