Most of those free proxies services publicly display the IP addresses they are using, making it trivial for any website to block them. By definition, they have access to all the HTTP traffic you send them. It would be best if you used those with cautions. Some proxies, such as the one used in this example, are free. Now that you know how to use web proxies with node-fetch, there are a couple of things to know before using them.įirst, not all proxy providers are equal. By using the node-https-proxy-agent, you will be able to easily forward all your requests through an HTTPS proxy.Ĭonst HttpsProxyAgent = require( 'https-proxy-agent') Ĭonst proxyAgent = new HttpsProxyAgent( '') Ĭonst response = await fetch( '',, bingo ! Things you should know about proxies. Unfortunately, Node-fetch does not natively support proxies. Most websites don't really like being scraped, and using proxies if one of the many tools you can use to scrape the web without getting blocked.Īnd as you will see, this is not as straight-forward as it seems. Web-scraping is the fact of programmatically fetching web page without opening a real-browser. However, on the server-side of things, there are many more use-cases. This API is primarily used to make asynchronous requests to load content on the browser side. Node-fetch's primary motivation was to implement a server-side API similar to window.fetch, a client-side one since it is implemented in the browser.
There are further settings which may need to be added that might be discussed in a future post.Node-fetch is a popular HTTP client library, with around twenty million downloads per week according to NPM, it is also one of the most downloaded NPM packages of all-time. In this example we’re simply telling NPM to ignore the errors, this is less secure importing your proxy certificate but a quicker way of working. Most proxies use SSL interception and replace the hosts SSL certificate with one of their own, you can have the URLs required added to any SSL Bypass policy by your proxy server admin, import your proxy servers CA into your NPM setup or tell NPM to ignore errors with SSL certificates Set the https proxy – Rememebr to replace the URL and port number with your specific values. Set the http proxy – Rememebr to replace the with your specific values. You can set each command globally by adding a -g at the end of the line. Using the command line to set NPM proxy variables.
