Impossible to work with Json in TypeScript without as any

[eladb]

Use Case

In our SDK TypeScript code and in Wing code written in TypeScript, every API that accepts/returns Json is awkward to use because it basically requires as any.

For example:

import { cloud, lift, main } from "@wingcloud/framework";

main((root, test) => {
  const b = new cloud.Bucket(root, "Bucket");

  const fn = new cloud.Function(
    root,
    "Function",
    lift({ b }).grant({ b: ["putJson"]}).inflight(async (ctx) => {
      await ctx.b.putJson("hello", "world");
//                                 ^^^^^^^ Argument of type 'string' is not assignable to parameter of type 'Json'.ts(2345)

      return undefined;
    })
  );
});

Proposed Solution

Not ideal but at least it will keep things within the framework and not escape the type system: perhaps we can offer some utility methods on the Json type to make it easy to construct:

Json.fromString("hello");
Json.fromNumber(123);
Json.fromObject({ df: 123 });

Json.toString(myJsonString)
// ...
