NexApi/Use case

React development

Build a mock API for React without maintaining a temporary backend

Give a React app stable REST endpoints for development, demos, and integration testing, then inspect requests from the NexApi dashboard.

What this workflow solves

Go from idea to a stable HTTP contract without building every backend layer first.

React development moves faster when components can integrate with real HTTP behavior early. NexApi gives your team shared endpoints instead of local fixture files, so loading states, errors, requests, and response contracts can be tested against something closer to production.

Replace hard-coded component fixtures with shared HTTP endpoints.

Test loading, success, validation, and authentication flows.

Keep API response shapes consistent across the React team.

Use request logs to debug integration issues.

How it works

A short path from data model to usable endpoint.

01

Model the React data contract

Start with the TypeScript interface or JSON shape your components already consume.

02

Create matching endpoints

Build resource routes in NexApi with the expected method and response fields.

03

Swap the base URL

Point fetch, Axios, React Query, or another HTTP client at the NexApi endpoint.

04

Iterate against real requests

Use logs to see exactly what the React application sent while you refine the integration.

Request
const res = await fetch(
  "https://nexapi.run/r/demo/users"
);
const users = await res.json();
Response
{
  "data": [
    { "id": 1, "name": "Maya", "role": "admin" },
    { "id": 2, "name": "Noah", "role": "member" }
  ]
}

Fetch users from React

The client code stays ordinary HTTP code, so migrating away from a local mock does not require a custom SDK.

Built into NexApi

The API operations layer is already there.

Start small, then add the controls normally scattered across backend code, gateway config, webhook workers, and observability tools.

Visual endpoint builder

Configure methods, paths, request schemas, and response mappings from one interface.

API keys and access

Add API-key based access rules and keep public endpoints under control.

Rate limits and caching

Apply endpoint-level runtime controls without rebuilding the surrounding backend.

Webhooks and connectors

Connect REST APIs with Google Sheets, Slack, Discord, webhooks, Postgres, MySQL, and external REST APIs.

OpenAPI output

Keep the API contract consumable by documentation and developer tooling.

Logs and analytics

Inspect requests and usage from the same dashboard used to configure the API.

Good fit for

Teams that want to ship the API contract first.

React developers building before backend completion
Design-system teams creating data-driven examples
Frontend interview or portfolio projects
QA teams validating React API behavior

Frequently asked

Do I need a NexApi-specific React library?

No. React can call NexApi endpoints with standard fetch, Axios, React Query, SWR, or any other HTTP client.

Can the same endpoint be used by other clients?

Yes. Because the interface is HTTP and JSON, the same API can be consumed by mobile apps, scripts, or another web framework.

Can I protect the mock with an API key?

Yes. API access rules can be added when a shared demo or test endpoint should not be completely open.

Build it in NexApi

Turn this use case into a working endpoint.

Start with the contract you need now, then add keys, connectors, webhooks, analytics, and OpenAPI as the project grows.
