Node.js, a popular JavaScript runtime, enables the creation of server-side and network applications and can fetch data from remote APIs using a web proxy server to bypass restrictions and access geo-blocked content. Node-fetch is a library that extends the Fetch API in Node.js, allowing HTTP requests through proxies by working with HTTP agents like HttpsProxyAgent, which manages connections and supports HTTPS proxies. The article explains how to set up a Node.js project to use node-fetch and https-proxy-agent libraries for proxy requests, and highlights the limitations of simple proxy usage, which can be mitigated by more advanced proxy services like Bright Data. Bright Data offers a range of proxy types, such as residential, datacenter, ISP, and mobile proxies, which help in web scraping by providing features like geo-targeting, IP rotation, and session control, ensuring that your application remains unblocked. The Bright Data proxy service also includes a Proxy Manager and APIs to simplify proxy management and integration for various web scraping needs, promoting seamless access to websites or APIs without getting blocked or throttled.
