+In this tutorial, we will guide you through the process of configuring the OpenAI Reverse Proxy. The OpenAI Reverse Proxy allows you to securely integrate OpenAI API calls into your applications while maintaining control over the requests and responses. We will cover the necessary steps to set up and configure the reverse proxy effectively.
+
+Here we will use a simple Node.js script for reverse proxy and deploy it in Hugging Face. We can also deploy it in our local computer manually with Node.js. But we are using Hugging Face, so that we can get the OpenAI Reverse Proxy URL. We can then use that API url on Janitor AI API or other services.

+Openai Reverse Proxy Setup
+Space Name: Enter the name for your space (openai-reverse-proxy).
+
+Select Space SDK: Docker (We will use Docker to deploy).
+
+
+Choose Docker Template: Blank
+
+Everything else can be default.
+
+Click Create Space.
+
+
+Now a new machine with 2vCPU 16GB RAM will get provisioned for free.
+
+Create Dockerfile
+Once you have created your space, you will be redirected to the App page. This page contains all details about your deployment.
+
+
+Scroll a little below to see where it says “(Hint: Create the Dockerfile file right in your browser alternatively)”
+
+Openai Reverse Proxy Dockerfile
+Click Create to add our Dockerfile configurations.
+
+Copy the below code and add it to the Edit section input box.
+
+Dockerfile
+FROM node:18
+
+WORKDIR /app
+
+RUN npm install express express-http-proxy
+
+COPY . .
+
+EXPOSE 7860
+
+CMD [ "node", "server.js" ]
+The above configuration configures a Debian 11 machine with Node.js 18. Then installs the required packages and deploys the application to run on port 7860.
+
+Openai Reverse Proxy Dockerfile
+Click Commit new file to main.
+
+This will create a new Dockerfile inside your space.
+
+Configure OpenAI API Secret
+Now go to your space settings and scroll down to find Repository secrets.
+
+Openai Api Secret
+Click New Secret.
+
+In the popup box, enter the following.
+
+Name: OPENAI_KEY
+
+Secret value: Your API Key from OpenAI
+
+Openai Api As Secret Key
+Click Add new secret.
+
+Now you have added your OpenAI API key as a secret.
+
+Create Node.js file
+Now you need to create a server.js file with the reverse proxy configurations that can be used with your OpenAI API key.
+
+Go to Files in your space.
+
+Click Add file and then click Create a new file.
+
+Name your file: server.js
+
+Copy the below in your Edit section.
+
+server.js
+const express = require('express');
+const proxy = require('express-http-proxy');
+const app = express();
+const targetUrl = 'https://api.openai.com';
+const openaiKey = process.env.OPENAI_KEY
+const port = 7860;
+const baseUrl = getExternalUrl(process.env.SPACE_ID);
+
+app.use('/api', proxy(targetUrl, {
+  proxyReqOptDecorator: (proxyReqOpts, srcReq) => {
+    // Modify the request headers if necessary
+    proxyReqOpts.headers['Authorization'] = 'Bearer '+openaiKey;
+    return proxyReqOpts;
+  },
+}));
+
+app.get("/", (req, res) => {
+  res.send(`This is your OpenAI Reverse Proxy URL: ${baseUrl}`);
+});
+
+function getExternalUrl(spaceId) {
+  try {
+    const [username, spacename] = spaceId.split("/");
+    return `https://${username}-${spacename.replace(/_/g, "-")}.hf.space/api/v1`;
+  } catch (e) {
+    return "";
+  }
+}
+
+app.listen(port, () => {
+  console.log(`Reverse proxy server running on ${baseUrl}`);
+});
