  **Tip:** There is a [.env.defaults](https://github.com/bennycode/coinbase-pro-node/blob/main/.env.defaults) file which serves as a template. Just remove its `.defaults` extension and enter your credentials to get started. Do not commit this file (or your credentials) to any repository!
  +### Web Frontend Applications
  +
  +The "coinbase-pro-node" library was built to be used in Node.js environments BUT you can also make use of it in web frontend applications (using React, Vue.js, etc.). However, due to the [CORS restrictions](https://developer.mozilla.org/docs/Web/HTTP/CORS) of modern web browser, you will have to use a proxy server.
  +
  +A proxy server can be setup with webpack's [DevServer proxy configuration](https://webpack.js.org/configuration/dev-server/#devserverproxy) or [http-proxy-middleware](https://www.npmjs.com/package/http-proxy-middleware).
  +
  +Here is an example:
  +
  +**Backend**
  +
  +```typescript
  +import {createProxyMiddleware} from 'http-proxy-middleware';
  +import express from 'express';
  +
  +const app = express();
  +
  +app.use(
  + '/api-coinbase-pro',
  + createProxyMiddleware({
  + target: 'https://api.pro.coinbase.com',
  + changeOrigin: true,
  + pathRewrite: {
  + [`^/api-coinbase-pro`]: '',
  + },
  + })
  +);
  +```
  +
  +Later on, you can use the proxy URL (`/api-coinbase-pro` from above) in your web application to initialize "coinbase-pro-node" with it:
  +
  +**Frontend**
  +
  +```typescript
  +const client = new CoinbasePro({
  + httpUrl: '/api-coinbase-pro',
  + apiKey: '',
  + apiSecret: '',
  + passphrase: '',
  + useSandbox: false,
  +});
  +```
  +
