Flux API JavaScript SDK for RunAPI

The flux api JavaScript SDK is the language-specific package for Flux 2 on RunAPI. Use this flux api package for text-to-image, image-to-image, edit, and creative production flows when your application needs JSON request bodies, task status lookup, and consistent RunAPI errors in JavaScript.

This flux api README is the JavaScript package guide inside the public flux2-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/flux-2; for API reference, use https://runapi.ai/docs#flux-2; for SDK docs, use https://runapi.ai/docs#sdk-flux-2.

Install

npm install @runapi.ai/flux2

Quick start

import { Flux2Client } from '@runapi.ai/flux2';

const client = new Flux2Client();
const task = await client.generations.create({
  // Pass the Flux 2 JSON request body from https://runapi.ai/docs#flux-2.
});
const status = await client.generations.get(task.id);

Use create when you want to submit a task and return quickly, get when you need the latest task state, and run when a script should create and poll until completion. In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

Language notes

Use the TypeScript types in src/types.ts and the resource classes under src/resources when building image applications. The available resources include generations. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
