DevBentoConvert REST API Response to TypeScript
Generate TypeScript types from a typical REST API JSON response. Paste your API JSON output and get complete typed interfaces for your TypeScript app.
// Generated by DevBento — json-to-typescript
interface RootAddress {
street: string;
city: string;
zip: string;
}
interface RootPostsItem {
title: string;
likes: number;
}
interface Root {
id: number;
name: string;
email: string;

}Convert REST API Response to TypeScript
This example shows how to generate TypeScript types from a typical REST API response. The pre-filled JSON represents a user object with nested address, array of roles, and array of post objects.
What You Get
The tool produces:
- A
Rootinterface with all top-level fields typed - A
RootAddressinterface for the nested address object - A
RootPostsIteminterface for each post in the array - Correct types:
stringfor text,numberfor IDs and counts,booleanfor flags,string[]for string arrays
How to Use
- The example loads with a sample user API response already filled in
- Toggle between Interface and Type output modes to see both styles
- Copy the generated types and paste them into your TypeScript project
- Replace the sample data with your actual API response to generate types for your specific endpoint
Real-World Pattern
Most REST APIs return objects with nested structures and arrays. This example covers the common pattern: flat fields at the top level, a nested object for related data, and arrays for collections. The generated types give you full IntelliSense support when working with API responses in TypeScript.
