Users can only do as much as is allowed by the developerįor example, we might want to limit the number of requests an unsubscribed user can make to a public API to 1,000 requests per month.There is a reduced risk of attack, i.e., improved security.Thus, it is a technique that allows us to handle user requests based on some specified constraint such that: In this context, network refers to the line of communication between a client (e.g., a web browser) and our server (e.g., an API).
Rate limiting is a technique used to control the amount of incoming or outgoing traffic within a network.
#FLEXIHUB NODE LIMIT REACHED HOW TO#
How to implement rate limiting in Node.js.We will make sure to break things down as much as possible so that you can easily understand every concept we end up exploring. If you’re lacking some or all of these, do not feel intimidated. Experience working with middleware in Node.Working knowledge of how to build REST APIs in Node.Working knowledge of how servers handle requests.In order to follow along effectively as you read through this article, you should have the following: We will also get practical by implementing a selected approach in Node.js. In this article, we will examine the different approaches to implementing rate limiting, as well as the pros and cons of each. In general terms, it allows us to control the rate at which user requests are processed by our server. Rate limiting is a very powerful feature for securing backend APIs from malicious attacks and for handling unwanted streams of requests from users. Understanding and implementing rate limiting in Node.jsĮditor’s note: This article was updated on 22 June, 2022 to align with the most recent version of Node.js and include more up-to-date information about rate limiting.
