Using Proxies with node-fetch
- Import the necessary modules
javascript
Copy code
const fetch = require(‘node-fetch’);
const HttpsProxyAgent = require(‘https-proxy-agent’);
- Define your proxy server
javascript
Copy code
const proxy = ‘http://your-proxy-server:port’;
const proxyAgent = new HttpsProxyAgent(proxy);
- Make a request using node-fetch with the proxy agent
javascript
Copy code
fetch(‘https://example.com’, {
agent: proxyAgent
})
