11 | Medusa AI Order Returns Assistant 12 |

13 | 14 | 15 | An AI Order Returns Assistant widget for the [Medusa](https://medusajs.com/) admin. You can use natural language to explain the situation, and it will extract all necessary data to create the return order. Built with [Medusa UI](https://docs.medusajs.com/ui), [OpenAI](https://platform.openai.com), and [Vercel AI SDK](https://sdk.vercel.ai). 16 | 17 | Feel free to take this code and use it to create any Medusa AI assistant you need. By editing the system prompt in `src/api/routes/admin/completion/order-returns.ts` and the functions in `src/util/gpt-functions/returns.ts` and `src/admin/widgets/assistants/order-assistant.tsx`, you can change its behavior and give it access to different admin hooks. 18 | 19 | **Disclaimer**: this code is the result of my experimentation, and is by no means optimized or actively maintained. 20 | 21 |

This widget requires an OpenAI platform account and API key. Go to https://platform.openai.com/account/api-keys to set this up. 32 | 2. You need a valid Medusa database. The fastest way to set this up is by using [create-medusa-app](https://docs.medusajs.com/create-medusa-app). 33 | 34 | ## Getting Started 35 | 36 | 1. Clone repo and install dependencies. 37 | 2. In your `.env` file, add an `OPENAI_API_KEY` environment variable containing your API key, and link your database: 38 | 39 | ``` 40 | OPENAI_API_KEY= 41 | DATABASE_URL= 42 | ``` 43 | 44 | 3. Start your dev server and log into the admin. Open any order details page and the widget will appear on the bottom of the page! 45 | -------------------------------------------------------------------------------- /index.js: -------------------------------------------------------------------------------- 1 | const express = require("express") 2 | const { GracefulShutdownServer } = require("medusa-core-utils") 3 | 4 | const loaders = require("@medusajs/medusa/dist/loaders/index").default 5 | 6 | ;(async() => { 7 | async function start() { 8 | const app = express() 9 | const directory = process.cwd() 10 | 11 | try { 12 | const { container } = await loaders({ 13 | directory, 14 | expressApp: app 15 | }) 16 | const configModule = container.resolve("configModule") 17 | const port = process.env.PORT ??
