This page is useful when you have one representative JSON object and want a quick TypeScript interface draft for inspection, prototyping, or contract discussion. It is not a project-wide model generator, and it should not be treated as if one sample can capture every variant your API might return.
The current implementation expects a top-level JSON object for this route. It generates interface names from nested keys and infers array structure from the first item only.
The browser creates one interface block for the root object and additional interface blocks for nested objects. Primitive arrays and optional fields are not deeply analyzed, so the output is best treated as a draft you will review and tighten manually.
| Example | Value |
|---|---|
| Input | One JSON object representing the payload shape you want to inspect. |
| Output | One TypeScript interface sketch with nested interfaces inferred from that sample. |
Check optional-looking fields, array item assumptions, unions, and naming cleanup. The page helps most when it gets you to a first interface draft quickly, not when it is mistaken for a final typing system.
No. The current TypeScript route expects a top-level object.
The page creates additional interfaces named from the nested keys.
Array shape is inferred from the first item only, so you should review it manually.
When you need a full project-ready model layer or many-sample reconciliation.
Generate lightweight TypeScript interfaces from a sample JSON object using browser-side shape inference.
